Latest Patents

Hanna's latest patents include "Time-synchronized pixel array and touch array crosstalk mitigation systems and methods." This invention describes systems, methods, and devices that mitigate display pixel and touch crosstalk noise. A touch processing system compensates touch scan data to reduce noise based on a luminance value. An image processing system determines the luminance value based on image data and the display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system can determine the proximity of a capacitive object to at least one touch sense region of the electronic display.

Another significant patent is for a "System for ambient light sensing or compensation." This invention involves an electronic display that includes an ambient light sensor (ALS) located beneath an active area to sense ambient light above the active area. The ALS features multiple response channels to perform fast sensing integration, synchronized with blanking periods of a pixel on the active area. An emission mask and a heat map are generated for the ALS, which are used to create a calibrated heat map for the ALS. This calibrated heat map is then utilized with display content to calculate crosstalk compensation for the ALS.
