Touch control type liquid crystal display array substrates and LCD device

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 invention relates to a liquid crystal display array substrate and a liquid crystal display device, and 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. The display screen is an indispensable human-machine communication interface in these devices. At present, the mainstream display screen adopts liquid crystal display device. [0003] In recent years, with the rapid development and application of information technology, wireless mobile communications and information appliances, in order to achieve more convenient, lighter and more user-friendly purposes, many information products have been converted from traditional keyboard or mouse input devices to A touch panel...

AI Technical Summary

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
