Abstract
A touch display driving circuit capable of responding to CPU commands, including: a first interface for receiving pixel data and touch configuration data; a second interface for coupling with a touch display; and a control unit, which drives the touch display via the second interface to show an image according to the pixel data, and executes a touch detection procedure on the touch display via the second interface, wherein the touch detection procedure is determined according to the touch configuration data.
Claims20
A touch display driving circuit capable of responding to CPU commands, comprising:
- a first interface for receiving pixel data and touch configuration data from a CPU, wherein said first interface transmits data in a serial manner or a parallel manner and said touch configuration data includes multiple control bits;
- a second interface for coupling with a touch display module;
- and a control unit, which drives said touch display module via said second interface to show an image according to said pixel data, and executes a touch detection procedure on said touch display module via said second interface, wherein said touch detection procedure is determined according to said touch configuration data;
- and said multiple control bits included in said touch configuration data are used to determine a connection configuration of at least one multiplexer, and a weighting configuration of at least one touch point.
