Touch-control type liquid crystal display device

Abstract

The invention relates to a touch-control type liquid crystal display device comprising a first base plate, a second base plate, a liquid crystal layer, a plurality of scanning lines, a plurality of data lines and a plurality of pixel units, wherein the first base plate and the second base plate are oppositely arranged; each pixel unit comprises a plurality of sub-pixels, each sub-pixel comprises a first common electrode, a second common electrode, a pixel switch element and a pixel electrode, wherein the first common electrode is arranged on the first base plate, the second common electrode is arranged on the second base plate, the pixel switch element is arranged on the first base plate, and the pixel electrode is electrically connected to the pixel switch element. The touch-control type liquid crystal display device also comprises a touch-control structure, a touch position output line and a touch detecting device, wherein the touch position output line is connected with the touch-control structure; the touch detecting device is connected with the touch position output line; the touch-control structure comprises a touch-control switch element and a touch unit, wherein the touch-control switch element is arranged on the first base plate; and when the touch-control type liquid crystal display device is touched, the touch-control switch element is electrically connected with the touch position output line. The touch-control type liquid crystal display device can realize multi-point touch to improve the display quality.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a touch-sensitive liquid crystal display device. Background technique [0002] In today's information society, people's dependence on electronic products is increasing day by day. Mobile phones, palmtop computers, personal digital assistants (PDAs) and other electronic products can be seen everywhere in life. In order to achieve more convenience, smaller size, stronger interaction and more humanization, the display panels provided by many electronic products integrate touch input functions to replace traditional peripheral input devices (such as keyboards or mice, etc.), so that The whole device appears more compact and lightweight. Therefore, the touch display panel with both touch and display functions has become one of the most popular products nowadays. [0003] Taking PDA as an example, its touch-sensitive touch panel is composed of a display (for example: thin film tr...
