Patent ID: 10963102

Abstract:
System and method for touch sensing and LED control for a touch screen. For example, the system comprises: a control chip including m first multiplexing terminals and n second multiplexing terminals, wherein m and n are integers greater than 2; k LEDs, wherein a rth LED of the k LEDs is connected to an ith first multiplexing terminal of the m first multiplexing terminals and to a jth second multiplexing terminal of the n second multiplexing terminals; wherein: the rth LED is in between the ith first multiplexing terminal and the jth second multiplexing terminal; r is an integer greater than 0 and less than or equal to k; i is an integer greater than 0 and less than or equal to m; j is an integer greater than 0 and less than or equal to n; and (m+n) touch-sensing capacitors.
