METHODS AND SYSTEMS FOR DISPLAY DEVICE MULTIPLEXING AND DEMULTIPLEXING

Abstract:

A method may include determining a display control signal for a display pixel in a display device. The method may further include determining a capacitive sensing control signal that corresponds to a capacitive scan for a sensing region. The capacitive scan may detect a location of an input object in a sensing region using various sensing elements disposed in the display device. The method may further include generating a multiplexed signal that includes the display control signal and the capacitive sensing control signal. The multiplexed signal may cause, using a demultiplexer disposed in the display device, the display device to perform the capacitive scan and update the display pixel.
