In-cell multi-touch display panel system

摘要

An in-cell multi-touch display panel system includes a multi-touch LCD panel and a touch display control subsystem. The multi-touch LCD panel has a TFT layer, a detection electrode layer, and a common-voltage and touch-driving layer. The detection electrode layer has M first conductor lines for performing touch detection by sampling touch detection from the M first conductor lines. The common-voltage and touch-driving layer has N second conductor lines for receiving common voltage in display and touch-driving signal in touch detection. In the detection electrode layer, there are pluralities of detection electrode areas in the intersections of first conductor lines and second conductor lines. Each detection electrode area is connected to a first conductor line by a touch-control transistor. The M×N touch-control transistors are divided in to N sets corresponding to N second conductor lines, respectively.
