METHOD FOR DETECTING TOUCH DISPLAY PANEL

摘要

A method for detecting a touch display panel which includes a plurality of conductive lines which are composed of a plurality of data lines and driving lines is used to detect capacitance characteristics of the touch display panel. Between the data lines and ground has at least one first capacitance module, between the driving lines and ground has at least one second capacitance module, and between the data lines and the driving lines has at least one capacitance. The method includes electing one as a detection line in the conductive lines for detecting capacitance characteristic, then inputting a detection voltage wave to the detection line and inputting the detection voltage wave to the conductive lines which are cross the detection line to eliminate capacitance characteristic of the capacitance; detecting capacitance characteristic between the detection line and ground at last.

1. A method for detecting a touch display panel by detecting capacitance characteristics of the touch display panel, wherein the touch display panel is electrically coupled to a driving circuit and includes a plurality of conductive lines which are composed of a plurality of data lines arrayed on the touch display panel along a first direction and a plurality of driving lines arrayed on the touch display panel along a second direction to cross the plurality of data lines with at least one first capacitance module between the data lines and a ground, at least one second capacitance module between the driving lines and the ground, and at least one first capacitance between the data lines and the driving lines, and the method comprising:
(a) electing one of the conductive lines as a detection line for detecting capacitance characteristic; and (b) inputting a detection voltage wave to the detection line and inputting the detection voltage wave to the conductive lines which cross the detection line to eliminate capacitance characteristic of the first capacitance so as to detect capacitance characteristic between the detection line and the ground.
