Abstract

The invention provides a TFT liquid crystal display apparatus having a touch function, including: a first electrode layer, having multiple first electrodes and multiple thin film transistors, wherein each of the multiple thin film transistors has a source coupled to a source control unit, a gate coupled to a gate control unit, and a drain coupled to one of the multiple first electrodes and to one of multiple storage capacitors; a liquid crystal display layer, located above the first electrode layer; a transparent electrode layer, being located above the liquid crystal display layer and having multiple transparent strip electrodes; and multiple switches, of which each has a control end coupled with a mode control signal, a first contact coupled to one of the multiple transparent strip electrodes, a second contact coupled to a common voltage generation unit, and a third contact coupled to a touch detection unit.

Description

technical field [0001] The present invention relates to a touch device, in particular to a thin film transistor liquid crystal display device with a touch function, which can use a liquid crystal display structure to execute a capacitive touch detection process. Background technique [0002] A common touch screen device is a touch module superimposed on a liquid crystal screen. However, this type of touch screen device has a large thickness, which cannot meet the light and thin market demand, and its cost is also high. [0003] In order to solve this problem, there is a design in the prior art that integrates the liquid crystal screen and the homogeneous material layer of the touch module. However, the reduced thickness of the touch screen device still cannot meet the requirements of some high-end products. [0004] There are existing designs that try to realize the touch function on the liquid crystal display, and the general method is to add additional electrodes on the ...
