  • SINGLE SUBSTRATE POLARIZER AND TOUCH SENSOR FOR DISPLAY SCREENS
    Publication number: 20240126116
    Abstract: Methods, apparatus and systems are provided for touch screen displays that utilize a polarizer and a touch sensor circuit that are manufactured on a single substrate, and in which the touch sensor circuitry may be directly printed onto a polarizer substrate to provide a combination of a polarizer and a touch sensor on the same single common substrate.

  • Systems and methods for increasing backlight uniformity for backlit display panels
    Patent number: 11651744
    Abstract: Systems and methods are provided for using logic-based compensation to optimize luminance uniformity of light emitting diode (LED) backlight panels employed for display panel assemblies such as liquid crystal displays (LCDs). These systems and methods may be implemented using a uniformity profile (e.g., uniformity lookup table “U-LUT”) in the LED backlight driving process to provide values to separately control luminance of different backlight segments of a LED backlight panel in order to improve backlight segment luminance uniformity.
