Abstract

The invention provides a touch screen integrated liquid crystal display panel which comprises an array substrate, a color film substrate, a display drive chip, a touch drive chip and a liquid crystal layer. The array substrate comprises data lines, pixel electrodes and public electrodes; each public electrode comprises a touch drive public electrode and a touch sense public electrode, the touch drive public electrode is connected with a public voltage source through a first switch tube, and the touch sense public electrode is connected with the public voltage source through a second switch tube; when the liquid crystal display panel performs detection on touch signals, the first switch tube and the second switch tube are switched to a connection state, and after time is set, the first switch tube and the second switch tube are switched to disconnection state. The invention further provides a liquid crystal display device. By the touch screen integrated liquid crystal display panel and the liquid crystal display device, display effect of the display panel can be guaranteed.

Description

technical field [0001] The invention relates to the field of displays, in particular to a liquid crystal display panel integrated with a touch screen and a liquid crystal display device. Background technique [0002] With the development of technology, touchable display screens are becoming more and more popular. The touchable display screen includes a touch sensor panel and overlapping display panels. After the display panel is arranged, part of the touch-sensitive elements of the touch sensor panel can be arranged on at least a part of the visible area of ​​the display panel. [0003] In this way, the display panel can complete various display functions, and the touch sensor panel can recognize touch actions on the touchable display screen. The touch sensor panel includes a driving line and a sensing line, and the driving line and the sensing line are generally made of a transparent conductive material (such as indium tin oxide, ITO, etc.). In this way, the touch sensor...
