Description

CROSS-REFERENCE

This application claims the benefit of U.S. Provisional Application Nos. 62/031,258, filed 31 Jul. 2014, and 62/190,580, filed 9 Jul. 2015, both of which are incorporated herein in their entireties.

FIELD

The disclosure relates to a systems and methods for conveying content to and displaying content on merchandising communication systems and systems and methods for monitoring various environments, particularly retail environments.

BACKGROUND OF THE INVENTION

There are a variety of retail options for displaying a variety of information in retail environments, including, pricing, labeling, promotions, etc. Traditionally, this information has been provided using print systems, including slide-in paper system, plastic label systems, adhesive label systems, etc. More recently, there has been increased interest in utilizing digital or electronic systems to display such information.

The utilization of high definition display technology, including plasma displays, LCD displays (including those backlit by light emitting diodes (LEDs)), etc., in such applications was considered, but such systems are expensive, limiting their scope of commercial adoption. For example, many retail outlets have large numbers of shelves that require the display of information. Systems described in US 2014/0139548 utilize only a single display strip per aisle for displaying the prices of products on a multiple shelves. This approach may alleviate some of the cost-prohibitive nature of such devices, but leaves a great deal to be desired as the prices are no longer located adjacent the product, resulting in frustrated customers having to search for prices. In addition, such systems utilize displays that are not only expensive to install, but to replace. US 2010/0012600 suggests the use of such displays protrude into the aisles where customers can knock the displays off and/or otherwise damage the displays. The solution there was to provide a large housing below the shelf to secure the electronics and protect them from being damaged. However, these large systems are even more difficult and expensive to transport and install, and do not provide optimal display surface areas.

The utilization of less complex and cheaper displays have also been considered, including e-paper displays (EPD), and thin-film-transistor liquid crystal displays (TFT LCD). However, such solutions are not one continuous strip. Therefore, a retailer cannot manage and communicate with an entire shelf display or multiple shelf displays in a single action. Instead, such digital and print displays, while possibly being adequate for displaying pricing information, product information, etc., they must be managed individually and do not have the ability to display complete aisle cross-branding, customer communication, display true or full-spectrum color, or full motion video and/or animation. Typical TFT displays for such applications are limited to displays that are 480 pixels wide by 272 pixels high, limiting the viability of such solutions. With graphics cards having a 2048 pixel wide by 1152 pixel high capability, such displays would need to be linked together with multiple displays and multiple graphics cards, requiring sophisticated and expensive synchronization software. Further, such systems would be limited to a maximum of twelve displays, equivalent to a five-foot section of tethered displays, through a single display server. In addition, such displays have relatively poor brightness—e.g., generally only up to about 25 NITS—and angle and distance legibility parameters—e.g., generally up to a maximum of about 2-3 feet at a 90 degree viewing angle and about 1-2 feet at a 25 degree viewing angle.

DETAILED DESCRIPTION OF THE INVENTION

In certain embodiments, the light emitting diode displays provided herein is a high aspect ratio light emitting diode display strip, systems comprising the same and components thereof. In specific embodiments, the display strips are useful for and/or configured for retail applications, such as to be integrated with or attached to retail scaffold, such as (e.g., the front surface of) a shelf. In specific applications, the shelf is a retail shelf.

FIG. 1 illustrates an exemplary high aspect ratio LED display unit 100 provided herein. The exemplary display unit comprises a first LED display component 101 and a second LED display component 102. Each exemplary display unit comprises an array of LED pixels 103, the array comprising 32 LED pixels in a first dimension 104 and 80 LED pixels in a second dimension 105, the display unit as a whole comprising an array of 160 LED pixels by 32 LED pixels. In addition, the exemplary display unit comprises a housing body 106, comprising a front surface 107 and rear surface 108 and having a length 109, a height 110, and a depth 111. The front and rear surfaces are optionally flat or contoured, depending on the specific application. The exemplary display unit further comprises a forward facing (e.g., positioned to face outward from the front surface of the) sensor (e.g., motion detector or camera) 112 situated in an approximately central position along the length of the display unit. In some embodiments, the sensor (e.g., camera) is located in a forward facing position on an upper portion of the display unit (e.g., as displayed in FIG. 1), on a lower portion of the display unit (e.g., if the display unit of FIG. 1 were flipped over), or any other suitable position. In exemplary embodiments, the display unit 100 comprises one or more chaining (e.g., daisy-chaining) connectors 113, e.g., configured to receive and/or convey, provide or transmit display information (e.g., to additional display units—not illustrated). FIG. 14 illustrates the rear surface of an exemplary display unit 1400 provided herein. In some instances, the display unit comprises a power input 1401 and a power output 1402 (e.g., a simple two pin power connector, such as Molex), e.g., configured to daisy chain power to one or more additional display unit. In certain instances, the display unit comprises a display information input 1403 and a display information output, e.g., configured to daisy chain data to one or more additional display unit. In some instances, the display unit further comprises one or more data input and/or output 1404 and 1405 (e.g., a USB type output, such as USB 3.0, USB 2.0, mini USB, micro USB, or the like), such as a sensor information output and/or a sensor information input (e.g., configured to receive and/or convey sensor information from one or more sensor). In specific instances, the two data outputs 1404 and 1405 are data outputs for conveying output signals away from the display unit 1400 from the forward sensor 112 and the rear sensor 1408. In some instances, display units provided herein are integrated with a shelving system, or the like, and in other instances, the display units are configured to be capable of being attached to retail scaffold, such as a shelf (e.g., the front edge thereof), e.g., using one or more bracket or magnet 1407.

As illustrated in the cross-sectional view of FIG. 18, in some embodiments, a display unit 1800 provided herein comprises a display surface 1801 (e.g., comprising an LED array, which is optionally coated 1803, such as with a resin to protect the LED pixels 1804) is configured to face in a first direction 1805 and the camera 1806 (e.g., lens thereof) is configured to face in a second direction 1807 (e.g., a direction about 90 degrees to 180 degrees or about 135 degrees to about 180 degrees opposed to the first direction). In specific embodiments, the first and second directions are parallel and opposed (i.e., 180 degrees opposed), such as illustrated in FIG. 18. In some instances, the camera 1806 has an angle of view 1808 (e.g., any suitable angle 180 degrees or less, such as about 120 degrees), the second direction 1807 bisecting the angle of view 1808. In some embodiments, the display unit further comprises a second camera 1809, configured to face in a third direction 1810 (e.g., a direction 0 degrees to about 90 degrees aligned with the first direction). In some instances, the second camera 1809 has an angle of view 1811 (e.g., any suitable angle 180 degrees or less, such as about 60 degrees), the third direction 1810 bisecting the angle of view 1811. In some embodiments, the first direction and third direction are aligned within 0 degrees of each other (i.e., parallel as illustrated in FIG. 18). In other embodiments, the first and third directions are aligned within 90 degrees of one another (e.g., within 60 degrees, within 45 degrees, within 30 degrees, or the like of one another).

In certain embodiments, such as illustratively displayed by way of non-limiting example in FIG. 19, the display unit 1901 comprising a viewable display 1902 (e.g., comprising an array of coated 1903 and viewable LED pixels 1904) is attached to or integrated with a shelf 1911 and is configured to face in a first direction 1905. In some embodiments, provided herein is a shelving system (e.g., retail shelving system) comprising a plurality of shelves comprising one or more display unit attached to or integrated therewith. In some embodiments, the display unit comprises a first sensor configured to detect product in proximity to the display unit. In specific embodiments, the first sensor is a camera 1906 configured to face a second direction 1907, e.g., in a rear facing direction, as discussed herein. In some embodiments, provided herein is a system (e.g., inventorying system) wherein a camera is affixed to or integrated with a shelving unit and is configured to capture and/or convey information about objects (e.g., product or merchandise) situated in proximity to (e.g., on a shelf below) the camera. In specific embodiments, the camera is integrated with a display unit provided herein, the camera being configured to be accepted into the display unit housing on the lower half, e.g., lower third or lower quarter, of the housing. In some embodiments, this configuration allows the camera to hang below the bottom face of a shelf and/or be in a better position to view objects in proximity to the camera. In certain embodiments, the first sensor is configured to detect objects 1912 (e.g., product or merchandise) in proximity to the display unit or first sensor and to send output signals (e.g., to a system controller) conveying information about the objects in proximity to the first sensor. In some embodiments, a system controller (not illustrated in FIG. 19) comprises a module configure to compare sensor information received from the first sensor (e.g., an image of an object captured by a camera) to information (e.g., retrieved from a data store) about an object assigned to be in proximity to the first sensor (e.g., and a module configured to access a data store configured to store accessible information regarding objects assigned to be in proximity to the sensor). In some embodiments, the module is configured to compare images of the objects in proximity to the sensor to images of objects assigned to be in proximity to the sensor. In other specific embodiments, (e.g., wherein the sensor is an RFID sensor) the module is configured to compare RFIDs of objects in proximity to the sensor or display unit to RFIDs of objects assigned to be in proximity to the sensor or display unit. In yet other specific embodiments, (e.g., wherein a sensor film is placed on the shelf to which the display unit is attached or integrated) the module is configured to compare a sensor state (e.g., weight) of the objects present on the shelf to information about the state (e.g., weight of) an object assigned to be on the shelf (and, e.g., a module configured to divide the total weight on the shelf by the weight of an object assigned to be on the shelf to arrive at the number of objects assigned to be on the shelf that are on the shelf). In still other specific embodiments, the module is configured compare the amount of space taken up proximity to the sensor (e.g., on a shelf) compared to the amount of space taken up by each object assigned to be in proximity to the sensor. For example, a module is configured to look for a pattern on the shelf (e.g., markers on a shelf). As an example, when the shelf is empty, each foot of shelving has x (10-1000, such as 216—one by one inch for an 18″ deep shelf per 1′ of shelf) number of markers (e.g., actual markers—such as dots, or a program construct thereof), and none of the markers are obstructed by product. In some instances, the module is configured to compare the number of markers obstructed to the number of markers each object assigned to be at the location would obstruct if located on the shelving. As such, in some embodiments, a controller module herein is configured to count visible markers on a shelf, compare the number of markers assigned to be in proximity to the sensor to the number of markers visible, and further compare the number of non-visible markers to the number of markers obstructed by an object in proximity to the sensor (e.g., in order to make a determination of the number of assigned objects—product or merchandise—in proximity to the sensor). In addition, in some embodiments, the display unit comprises a sensor configured to detect the sensor state of an operable parameter of the content displayed on the display unit, such as, e.g., a motion detector, forward facing camera (e.g., the configuration of which is described herein, particularly facing in a third direction 1910, such as that is within 90 degrees of the first direction), or other sensor suitable for detecting the presence of a person (e.g., customer in a retail environment) in proximity to the display unit.

In some embodiments, provided herein is a display unit comprising a power supply (e.g., a DC/DC converter or an AC/DC converter). In certain embodiments, a display unit provided herein is configured to receive power and display information via a single source, such as over Ethernet. In other embodiments, a display unit provided herein is configured to receive power and display information via different sources. In some embodiments, display units provided herein further comprise power regulators, e.g., to ensure a stable voltage provided to the display unit components. In some embodiments, display units provided herein additionally comprise one or more LED driver, e.g., configured to control the current provided to the LED array, which in some instances reduces the risk of LED failure.

Display units provided herein are configured to receive display information from wired and/or wireless sources. In certain embodiments, the display unit(s) (e.g., strip) comprises a receiver for receiving information (e.g., digital information). In various embodiments, the receiver comprises an input, such as a wired information input (e.g., a port) (e.g., a USB (e.g., USB 1.0, USB 2.0, USB 3.0) input, a modular connector input (e.g., 4 position 4 contact (4P4C), 6P6C, 6P2C, 6P4C, 6P6C, 8P8C, 10P10C, or similar modular connector)), an Ethernet input, a cat5 input, a cat5e input, a cat6 input, a micro USB input, a mini USB input, a registered jack (e.g., rj11) input, a component input, a RCA input, a coaxial input, a digital visual interface (DVI) input, a video graphics array (VGA) input,) a wireless information (e.g., WiFi, 4G, 3G) input, or the like.

In specific embodiments, the identifier is associated with the location of the display strip. In further embodiments, the one or more processor is configured to execute an identification module configured to determine an identifier associated with the display strip in which the processor is located. In certain embodiments, the one or more processor is configured to execute a content identification module configured to identify local display information to be displayed on the display unit in which the processor is located. In some embodiments, the local display information is a subset of global system display information received by the display unit receiver. In certain embodiments, the one or more processor is configured to decompress global system display information or a subset thereof—such as the identified local display information.

FIG. 2 illustrates an exemplary display unit 200 provided herein, wherein the display unit is configured to receive power and display information over Ethernet (using Ethernet protocols, or using a cat5, cat5e, cat6 or similar Ethernet type cable using other suitable protocols). The display unit comprises an optional power supply or power converter 201 configured to receive integrated display information and power 204, and an optional power regulator 202 configured to provide a suitable power source to the display unit (e.g., various components thereof). In some embodiments, the power supply or power converter is configured to convert received DC voltage to a suitable DC voltage (e.g., about 3 Vdc to about 5 Vdc) and the power regulator is configured to regulate the voltage (e.g., at about 3 Vdc to about 5 Vdc). The exemplary display unit 200 further comprises a display information receiver 203, such as the Ethernet receiver illustrated, and a processor 205, such as the FPGA illustrated. In certain embodiments, the processor 205 is configured to determine the display information to be displayed on the LED array 206. Optional LED drivers 207 are also included.

FIG. 4 illustrates a retail system 400 comprising multiple display units 401 provided herein. The display units are optionally affixed to and/or integrated with retail shelving 402. As is illustrated, given the cost effective nature of the displays, it is possible to utilize the display units 401 provided herein to provide specific display content for each product 403 on the shelves, even when the shelves are in complex configurations. In some embodiments, the system comprises one or more display unit comprising a sensor 404 (e.g., camera) configured to detect a sensor state, such as proximity to the sensor or a display unit comprising the sensor, and/or near a display unit comprising the sensor. In some instances, only a single sensor comprising display unit is needed to detect, for example, proximity to several (e.g., nearby) display units. For example, while each or multiple display units of a system optionally comprise a sensor, FIG. 4 illustrates a single display unit comprising a sensor 404. In some embodiments, by reducing the number of display units comprising a sensor, an even more cost effective system is achieved.

FIG. 5 illustrates an exemplary segmentation schematic of graphic or sending card display configurations into smaller height segments used in the display units and systems provided herein. As illustrated, an exemplary graphics (or sending) card 501 (e.g., QWXGA graphics card) provides image content to a pixel array 502 (e.g., 2048×1152). In specific instances, a single QWXGA graphics card of 2048×1152 supports 2,359,296 pixels in a system provided herein. Optionally, other graphics (or sending) cards are alternatively utilized to prepare other segmentation schemes. Other graphics cards or sending cards supporting various graphics arrays, such as XGA (1024×768), WXGA (1366×768), XGA+ (1152×864), WXGA+ (1440×900), SXGA (1280×1024), SXGA+ (1400×1050), WSXGA+ (1680×1050), UXGA (1600×1200), WUXGA (1920×1200), and many other types are optionally utilized. In specific embodiments, graphics or sending cards provided herein support a system comprising more pixels. For example, in some embodiments, dual sending cards provided herein support twice as many pixels. Further, in some embodiments, the system is configured to provide failover (e.g., by being configured to provide display information to a first and a last display unit of the system), thereby support half as many pixels. Segmentation of such a 2048×1152 array provides, for example, forty eight (48) segments 503 for display units having a height of 24 pixels. In other examples, using such a segmentation scheme is used to provide content to 36 segments for display units having a height of 32 pixels. In some embodiments, systems provided herein are configured as continuous displays (e.g., limited only by the display size desired), e.g., utilizing such techniques. FIG. 6 illustrates the logical layout on a shelf face of such a segmentation configuration (e.g., to create a width of greater than the pixel array width generally supported by a specific graphics card, such as a width greater than 2048 for QWXGA graphics cards). In some embodiments, provided in a system, e.g., a controller thereof, is a segmentation module configured to segment a graphics array to provide display content for a high aspect ratio system display array (e.g., a system display array of greater than that typically supported by the graphics card). In such embodiments, segmentation allows for a single graphics card to provide display content to a very high aspect ratio system display array of 98,304×24 for displays having a height of 24 pixels (e.g., up to over 900 display units having an LED array of 160×24) or 73,728×32 for displays having a height of 32 pixels (e.g., up to over 450 display units having an LED array of 160×32). Further, as illustrated in FIG. 5, with additional (n) graphics cards 504, additional display content is optionally provided to additional (n) arrays 505 that are similarly segmented. As is illustrated in FIG. 7, however, global and local display content is not limited by the segment or display sizes. In some instances, content segments optionally span two or more adjacently configured display units. Depending on how the products are arranged, for example, segmented content (701-708) is optionally stitched together (e.g., by a stitching module discussed herein) in any suitable manner.

In some embodiments, provided herein is a display system comprising one or more display unit and a controller. FIG. 16 illustrates an exemplary system 1600 comprising a controller 1601 and one or more display unit 1602. A single controller is illustrated comprising a plurality of controller subunits combined to serve the function of the system controller. In some instances, a controller comprises one or more processor configured to execute one or more controller program module. Exemplary program modules comprise, by way of non-limiting example, a sensor state identification modules (e.g., configured to monitor or detect sensor states, including operating parameters thereof), content identification module (e.g., configured to identify predetermined information to be provided to the one or more system display units based on the status of a sensor state), a content stitching module (e.g., configured to stitch the predetermined information (e.g., corresponding to local display information to ultimately be displayed at the display unit(s)) together, such as to form a global system display information, a content compression module (e.g., configured to compress display information), or combinations thereof.

In some embodiments, the process further comprises displaying video, images, and/or text associated with the display information on the one or more display units.

In specific embodiments, the sensor output signal further comprises information that identifies the sensor from which the output signal originated. In some instances, this is useful in system comprising multiple display units and multiple sensors. In certain embodiments, the method further comprises determining the identity of the sensor based on the information that identifies the sensor (a sensor identifier) from which the output signal originated.

In certain embodiments, the global system display unit is stitched in a logical order (e.g., as illustrated in FIG. 5 and FIG. 6) to allow for correlation with the correct display information with the correct display units, e.g., based on which display unit(s) are associated with which sensors, as well as how (e.g., order, location, etc.) the display units are associated with the sensors (which can be determined, e.g., by accessing a display unit registry and/or map).

FIG. 12 illustrates an exemplary retail system 1200 provided herein comprising a first display unit 1211 comprising a first sensor (e.g., camera), a second display unit 1212 comprising a second sensor (e.g., camera), and multiple additional display units 1213. In some instances, the first sensor 1211 is configured to detect multiple sensor states, such as in sensor zones 1201-1205. In some instances, sensor output signals from the sensor in display unit 1211 comprise information regarding sensor states in sensor zones 1201-1205. For example, in the illustration, a person is located in front of the shelving system in sensor zones 1204 and 1205. For example, therefore, the sensor in display unit 1211 is configured to send output signals comprising information about sensor states 1201-1205, and, receiving that information, the controller comprises a module configured (e.g., based on the sensor identity or identifier and the sensor state information) to identify the sensor state of sensor zone 1201 as having no person in sensor zone 1201, identify the sensor state of sensor zone 1202 as having no person in sensor zone 1202, identify the sensor state of sensor zone 1203 as having no person in sensor zone 1203, identify the sensor state of sensor zone 1204 as having a person 1210 in sensor zone 1204, and identify the sensor state of sensor zone 1205 as having a person 1210 in sensor zone 1205. In such examples, the controller is also configured to receive information from a second sensor (in display unit 1212), and one or more module configured to identify the sensor state of sensor zones 1206-1209 as having no person located therein. In some instances, based on such sensor state identification, e.g., using system components and/or modules or processes described herein, specific display information for the various display units in the various sensor zones of the system is identified, retrieved, and stitched into global system display information that is provided to the system display units (e.g., wherein the display units are configured to identify the subset of global display information that is local thereto, and display such local display information). FIG. 13 illustrates an exemplary depiction of a retail store aisle comprising one or more retail display system provided herein.

In certain embodiments, display information provided to the display units and systems described herein is any suitable display information, including, by way of non-limiting example, video, images, text, and combinations thereof. As discussed herein, in preferred embodiments, display units provided herein comprise an array of LED pixels, the array having a height of 30 pixels or more. As illustrated in FIG. 15, such array sizing allows for up to at least 4 lines of aesthetically pleasing text, with spacing between the text. In addition, good quality resolution images (such as product logos, QR codes, and the like) and video can also be displayed. In certain embodiments, display units and systems thereof (or processors thereof) are configured to display text fonts having a height of (at least) 7 pixels and a width of up to (at least) 5 pixels 1501. In some embodiments, larger fonts are optionally utilized, such as those having a height of 14 pixels and a width of up to 10 pixels 1503. In some embodiments, QR Codes have a height and width of up to 29 pixels 1502. In certain embodiments, a display unit provided herein provides a single content segment (or tag) that extends along the entire width of the unit (e.g., 160 pixel wide segment 1500 of the unit illustrated in FIG. 15). In other embodiments, a display unit herein is optionally divided into multiple content segments, such as half the display unit (e.g., an 80 pixel wide segment), a quarter (e.g., a 40 pixel wide segment), or any suitable fraction of the display unit.

In various embodiments, display units and systems described herein are configured to alter display content (e.g., alter display information provided to the display units) based on a sensor state of the display unit or system. In some instances, as discussed herein, such sensor states include identifying “motion” or “no motion.” In further embodiments, sensor states include (and/or a sensor, e.g., camera, provided herein is configured to be able to detect), by way of non-limiting embodiment, “motion,” “no motion,” and “captive” (e.g., as determined by identifying a face—i.e., facial recognition). Other exemplary sensor states include, by way of non-limiting example, “in proximity” or “not in proximity.” In some embodiments, exemplary sensor states (e.g., based on information received from a rear facing camera) include “item out of place,” “no item out of place,” “inventory low,” “inventory high,” and/or “inventory acceptable.” In certain embodiments, exemplary sensor states (e.g., based on information received from environmental sensors, such as temperature and/or humidity sensors) include, by way of non-limiting example, “temperature acceptable,” “temperature high,” “temperature low,” “humidity acceptable,” “humidity high,” and/or “humidity low.” Generally, based on such determinations, systems provided herein comprise program modules configured to identify and provide specific display information (content) to the display unit(s) thereof. For example, in some instances, when a sensor state is identified as “no motion” for one or more display unit, the system is configured to provide specific (and predetermined) display information, such as logos or decals of the products located at (e.g., on a shelf at, above, or below) the display units identified as having a sensor state of “no motion,” but when the sensor state is identified as “motion” for the one or more display unit, the system is configured to provide different, specific (and predetermined) display information, such as text describing the product(s), the price of the product(s), and optionally a QR code for the product(s) located at (e.g., on a shelf at, above, or below) the display unit(s) identified as having a sensor state of “motion.” In other exemplary embodiments, when a sensor state is identified as an environmental state being below or above acceptable levels, an inventory state being below an acceptable level, or an item is out of place, the system is configured to provide specific (and predetermined) display information, such as a type of alert—e.g., a generic alert—e.g., that there is an “unacceptable” sensor state, or a specific alert depending on the “unacceptable” state identified.
