Abstract: The exemplary embodiments herein provide an electronic display with a display controller in electrical connection with the electronic display and adapted to direct the electronic display to operate per nighttime instructions if the present time is between sunrise and sunset, without accepting any input from an ambient light sensor, and direct the electronic display to operate per daytime instructions if the present time is between sunset and sunrise, without accepting any input from an ambient light sensor. The nighttime instructions may include a first setting for gamma while the daytime instructions may include a second setting for gamma. Sunrise and sunset transition periods can be calculated using Artificial Ambient Sensor Data (AAS), with further settings for gamma chosen based on the AAS data.

Abstract: The exemplary embodiments herein provide a method for environmental adaptation of electronic display characteristics, comprising the steps of determining the sunset and sunrise times for the day and determining whether the present time is between sunrise and sunset or between sunset and sunrise. An exemplary method would then proceed by selecting a gamma for the display based on whether the present time is between sunrise and sunset or between sunset and sunrise, and driving the display at the selected gamma. The gamma can further be selected based on Artificial Ambient Light Sensor (AAS) data, which can be calculated during sunrise and sunset transition times.

Abstract: The exemplary embodiments herein provide a method for controlling the luminance of an electronic display, including the steps of determining the sunset and sunrise times for the day and determining whether the present time is between sunrise and sunset or between sunset and sunrise.

In some embodiments, artificial ambient sensor (AAS) data is used to determine the desired backlight or display luminance. The AAS data may be adjusted for a sunset or sunrise transition time, as well as for an approximate percentage of cloud cover in the sky.

Said microprocessor is adapted to determine the sunset and sunrise times for each day and determine whether the present time is between sunrise and sunset or between sunset and sunrise. The microprocessor is further adapted to direct the power module(s) to drive the backlight at a daytime level if the present time is between sunrise and sunset, and direct the power module(s) to drive the backlight at a nighttime level if the present time is between sunset and sunrise.

Abstract: A system for controlling the cooling fan within an electronic display based on the amount of ambient light present. An ambient light sensor is used to measure the amount of ambient light which is contacting the display. To anticipate a temperature rise and lower the thermal inertia of the display, the fan speed is increased when high ambient light levels are measured at the exterior of the display. The ambient light sensor data may be used to apply a temperature correction factor to a temperature sensor within the display. Alternatively, the ambient light sensor data may be used to apply a fan speed correction factor to a desired fan speed (calculated based on a temperature sensor within the display). Multiple systems or methods can be used simultaneously within the display to cool several components which may heat and cool at different rates relative to one another.

Abstract: A device and method for preventing damage to products in a display case is disclosed. The display case includes a normally black transparent liquid crystal display (LCD) which is positioned between a front and rear glass of the door. A controller is electrically connected to the LCD which drives the LCD according to transparency data. The transparency data comprises various transparency levels for the LCD depending on the time of day.

Abstract: A system and method for remotely-identifying the components and/or software revisions within an electronic display. An electronic storage device may be placed within an electronic display assembly and placed in electrical communication with a network connection. The electronic storage device may contain identification numbers for one or more components or software revisions within the display. A computing device may be in electrical communication with the network connection so that the identification numbers on the electronic storage device may be accessed remotely. If a particular component or software revision is desired, the computing device may be used to search the contents of each electronic storage device at each display to determine which displays contain the desired component or software revision.

Abstract: Embodiments include systems, methods, and apparatus configured to record (A) protocol requests that specify display operations on a screen image and (B) information copied from a display buffer storing the screen image. Such embodiments may also be configured to record states relating to an appearance of an output of the display operations. In some of these embodiments, the copied information is stored in the form of pseudo-protocol requests.

Abstract: Exemplary embodiments provide a system and method for securely transmitting video data to an electronic display. The video data may be transmitted using a wired or wireless application. Raw video data is encoded as a plurality of JPEG frames. A plurality of primary packets are created which may contain one frame or a portion of a frame of video. Each primary packet contains a unique header with information about the packet and a unique security key. A redundant packet and header are created for each primary packet and header. After transmission each packet and header may be analyzed to determine if it was transmitted properly. If the primary packet was not transmitted properly or was an unintended transmission, the system may discard the primary packet and proceed with the redundant packet. If the redundant packet was not transmitted properly or was an unintended transmission, the entire frame may be discarded and the previously accepted frame may be repeated within the video decoder.

Abstract: Disclosed herein is a light emitting diode (LED) backlight assembly having a mounting substrate with a plurality of LEDs where an optically-isolated cavity is positioned near an edge of the mounting substrate. An information block LED is positioned within the optically-isolated cavity so that light emitted from the main LEDs do not interfere with the light emitted by the information block LED. A liquid crystal stack may be positioned above the LEDs where a portion of the liquid crystal stack is designated as an information block which can be measured by a light sensor. The optically-isolated cavity can be formed by light absorbing and/or reflecting material and may contain one or more walls of the backlight cavity.

Abstract: A system and method for displaying images or video on an electronic display. A unique identifier may be embedded within the frames of images or video and detected by a light sensor. The data from the light sensor is analyzed to determine if the proper image or video was actually shown at the display. Some embodiments analyze the data from the light sensor in real time and may stop displaying the image or video if the data is not in the format of a unique identifier. Using this embodiment, the system can prevent unintended images or video from being shown on the display.

Abstract: A system and method for displaying multiple images on a single display. A plurality of unique video sources may be provided where each video source provides video frames having a plurality of vertical lines. A portion of the vertical lines are captured for each video source and transmitted to the display. The partial video frames may then be re-assembled into a single video frame which can be shown on the display. The display contains a masking where only certain vertical lines are viewable at certain angles. The masking may allow two or three images to be simultaneously visible to the observer, depending on the angle of viewing the display. Wireless or wired transmission may be used. Some embodiments also use a sound focusing device which may be synced with the video source so that separate sound messages can also be observed depending on the angle of viewing the display.
