Publication number: 20220223094Abstract: A method and system for programming, calibrating and driving a light emitting device display, and for operating a display at a constant luminance even as some of the pixels in the display are degraded over time. The system may include extracting a time dependent parameter of a pixel for calibration. Each pixel in the display is configured to emit light when a voltage is supplied to the pixel's driving circuit, which causes a current to flow through a light emitting element. Degraded pixels are compensated by supplying their respective driving circuits with greater voltages. The display data is scaled by a compression factor less than one to reserve some voltage levels for compensating degraded pixels. As pixels become more degraded, and require additional compensation, the compression factor is decreased to reserve additional voltage levels for use in compensation.Type: ApplicationFiled: January 24, 2022Publication date: July 14, 2022Inventors: Arokia Nathan, Gholamreza Chaji, Stefan Alexander, Peyman Servati, Richard I-Heng Huang, Corbin Church

Patent number: 10235933Abstract: A display degradation compensation system and method for adjusting the operating conditions for pixels in an OLED display to compensate for non-uniformity or aging of the display.

Patent number: 10126807Abstract: Switching of power modes for touch screens is disclosed. In example embodiments a touch detect mode may be activated for touchscreen operation. The touchscreen may be a projected capacitance screen that includes force sensing based on piezo electric sensors. The touch detect mode may be a low power mode in which at least one channel, but fewer than all channels of the touch screen are monitored. When is determined that a touch event has occurred a switch to a scan mode for touchscreen operation may be performed. Scan mode may be a higher power mode in which all channels of the touch screen are scanned at least for position sensing. The touch detect mode monitoring may be implemented by monitoring the total charge on the at least one channel and providing a voltage signal. When the voltage signal meets predetermined criteria an indication of a touch event may be generated.Type: GrantFiled: February 17, 2015Date of Patent: November 13, 2018Assignee: Cambridge Touch Technologies Ltd.Inventors: Arokia Nathan, Jackson Chi-Sun Lai, Suk-Bae Cha, Corbin Church
