  • Patent number: 9019253
    Abstract: Systems and methods for adjusting a color space of a display. In one embodiment, the method for adjusting the color space of the display may include receiving image data to be rendered on the display and receiving an indication of an amount of ambient light impinging on the display. The method may then include rendering the image data in a first color space when the amount of ambient light is less than a threshold. Alternatively, the method may include rendering the image data in an expanded color space when the amount of ambient light is not less than the threshold. As such, the expanded color space may compensate for one or more color shifts in the image data caused by the ambient light.

  • Publication number: 20150103050
    Abstract: Disclosed embodiments relate to a force detection system that detects force exerted on a flexible display based upon changes in resistance and/or capacitance. In one embodiment, a method includes measuring a baseline comprising a baseline resistance or a baseline capacitance or both of a force measurement layer disposed within or overlaid on the display panel. The method further includes detecting a change in the baseline resistance or the baseline capacitance or both and calculating a change location where the change in the baseline resistance or the baseline capacitance or both occurred. The method also includes calculating a magnitude of the change in the baseline resistance or the baseline capacitance or both.

  • Publication number: 20140085213
    Abstract: A force sensor incorporated into a touch device, measuring deflection in a device stack, including compressible elements disposed between the device stack and the frame element. When the device stack is deformed, applied force is measured using the compressible elements, using capacitive sensing or strain measurements. The force sensitive sensor provides an applied force image for the touch device's surface. The applied force location [X, Y] can be determined from measures of cover glass tilt, force at particular points, and capacitive sensing of touch location.

  • Publication number: 20140063074
    Abstract: The present disclosure relates generally systems and methods for controlling current provided to display devices. A method for controlling the current may include receiving drive current values associated with subpixels in a display and receiving information that corresponds to an application type being rendered on the display and/or an indication of image data being rendered on the display. The method may then include reducing at least some of the drive current values based at least in part on the application type. Alternatively, the method may include reducing the at least a portion of the image data corresponding to the at least some of the drive current values has substantially similar luminance and color values. The method may then include supplying the subpixels with drive currents that correspond to the drive current values.

  • Publication number: 20130321361
    Abstract: Thermal sensors are disposed with OLEDs across a display of an electronic device to measure temperatures across the display surface. Thermal sensors may be used to create a temperature map across the display surface due to both the ambient environment and the internal environment of the electronic device. The thermal sensors may be disposed in the OLED layer, on a separate layer, or both. Thermal sensors may be disposed in a substantially 1:1 ratio with OLEDs or with zones of OLEDs. Both the temperature history and usage history for OLEDs may be recorded and processed to determine the age of each OLED. Controllers may adjust the driving strength of OLEDs or adjust the operation of components within the electronic device to compensate for aging or temperature based on the temperature map and age determination. Controllers may move static images from one part of the display to another less-aged part.

  • Publication number: 20130194199
    Abstract: Systems, methods, and devices are provided in which photodetectors disposed throughout a display are used to control the display brightness. The photodetectors are to be used for ambient light sensing, proximity sensing, or to compensate for aging OLEDs. In some embodiments, photodiodes are fabricated with OLEDs during the TFT fabrication process. In some embodiments, the photodetectors may be disposed throughout the display in zones containing OLEDs. The photodetectors are used to control the display brightness and color for the OLEDs in areas around each photodetector based on ambient light, aging, and/or nearby objects. A controller makes driving strength adjustments to the OLEDs in each zone independent of other zones. Photodetectors disposed throughout the display may improve proximity sensing and provide additional functionality to the device.

  • Publication number: 20130083080
    Abstract: A system and methods to extending the overall display area for a device. At or near the borders of a device, pixel pitch between adjacent pixels may be increased such that overall pixel placement may be provided closer to a border of a display of a device. In one embodiment, pixel drive circuitry may be located in the spacing between adjacent pixels. Additionally, various optical systems and techniques may be utilized to provide an appearance of a lack of a border around the display such as decreasing the size of border pixels, overdriving the border pixels, or utilizing a light pipe on a surface above the border pixels.

  • Publication number: 20080284600
    Abstract: A Radio Frequency Identification (RFID) system for managing and identifying locations for an RFID reader is disclosed. An expected location of a fixed radio frequency identification (RFID) reader is determined. A first signal is transmitted from the reader to a first RFID tag to determine whether the reader is at the expected location. The first tag is a fiducial RFID tag fixed at a first location. In one aspect, the reader receives a first response to the first signal from the first tag. The first response identifies the first location of the first tag. The first location is compared to the expected location. If the first location and the expected location are different, an alarm is triggered.
