Problems solved by technology

Generally, the touch-type liquid crystal display frequently used in public places is equipped with an additional touch panel on the surface of the liquid crystal display panel, but this will increase the overall thickness and weight of the display, and cannot meet the demand for thinning. The control panel will reduce the transmittance of the backlight of the LCD display, thus resulting in a decrease in brightness
Furthermore, adding a touch panel to the display panel will also increase the cost due to the addition of parts

Embodiment Construction

[0025] The specific implementation manners according to the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 A schematic diagram of the pixel structure of the first embodiment of the present invention is shown. For clarity, the color filter substrate is omitted from the figure. figure 1 Among them, 31 is a scan line, 32 is a data line, 33 is a storage capacitor electrode line, and 331 is an extension of the storage capacitor electrode line 33 . The scan line 31 and the data line 32 are vertically intersected to define a pixel area, and the pixel electrode 341 is formed in the pixel area, and the pixel electrode 341 and the storage capacitor electrode line 33 form a first storage capacitor Cst. The counter electrode on the substrate (refer to image 3 ) form a liquid crystal capacitor C1c. A first thin film transistor TFT1 is disposed at the intersection of the scan line 31 and the data line 32 .

Abstract

The present invention relates to a touch control type liquid crystal display array base panel which comprises a plurality of scanning beams, a plurality of data wires, pixel electrodes, stored capacitor electrodes and a first switch element; wherein, the data wires are perpendicular to the scanning beams, and are crossed and arranged for limiting pixel areas; the pixel electrodes are formed in the pixel areas; the stored capacitor electrodes and the pixel electrodes form a first stored capacitor; the data wires convey data signals to the pixel electrodes through the first switch element; the array base panel also comprises signal checking wires, touch control electrodes formed in the pixel arrears, a second switch element and a converter; the touch control electrodes and the storing capacitor electrodes form a second stored capacitor; the signal checking wires input or output voltage signals to the touch control electrodes through the signal checking wires; the converter is used for controlling the input or the output of the voltage signals on the signal checking wires. Therefore, the touch control type liquid crystal device of the present invention has the advantages of light weight, small thickness, low cost and high display brightness.

Description

technical field [0001] The present invention relates to a liquid crystal display array substrate and a liquid crystal display device, in particular to a touch-sensitive liquid crystal display panel and a display device thereof. Background technique [0002] With the increasing development of technology, digital tools such as mobile phones, personal digital assistants (PDAs), and notebook computers are all developing in the direction of convenience, multi-function and beauty, and the display screen is an indispensable human-machine communication interface in these devices At present, the mainstream display screen adopts a liquid crystal display device. [0003] In recent years, with the rapid development and application of information technology, wireless mobile communications and information home appliances, in order to achieve more convenient, lighter and more humanized purposes, many information products have been input from traditional keyboards or mice and other devices....
