Problems solved by technology

However, after the touch panel and the liquid crystal display assembly are assembled into a touch-sensitive liquid crystal display device, there may be a problem that static electricity cannot be discharged.
That is to say, the static electrodes generated by the touch panel in the touch-sensitive liquid crystal display device may be directly introduced into the control circuit board or other data processing devices, thereby damaging the electronic components and making the product inoperable

Embodiment Construction

[0052] refer to figure 2 , which is a schematic cross-sectional view of the touch-sensitive liquid crystal display device according to the first embodiment of the present invention. The touch-type liquid crystal display device 200 is mainly composed of a housing 210 , a liquid crystal display component 220 , a touch panel 230 , a transparent conductive layer 250 , a control circuit board 260 and a conductive buffer 270 . The features of the above-mentioned components will be described below.

[0053]The touch panel 230 is located above the liquid crystal display unit 220 , and has a transparent conductive layer 250 on the touch panel 230 . The material of the transparent conductive layer 250 is, for example, indium tin oxide (ITO) or indium zinc oxide (IZO). In addition, the control circuit board 260 is electrically connected to the liquid crystal display unit 220 and the touch panel 230 for receiving control signals from the touch panel 230 and sending display signals to th...

Abstract

A touch-type liquid crystal display device at least includes a shell, a liquid crystal display component, a touch panel, a transparent conductive layer, a control circuit board and a conductive buffer. There is a transparent conductive layer on the surface of the touch panel, and the conductive buffer is arranged between the shell and the transparent conductive layer. The conductive buffer can be electrically connected with the electrically grounded shell or the conductive component shell in the electrically grounded liquid crystal display assembly, to discharge static electricity. The touch liquid crystal display device can prevent static electricity from being introduced into the control circuit board through the touch panel, and can effectively export static electricity to protect the electronic components in the control circuit board.

Description

technical field [0001] The present invention relates to a touch-sensitive liquid crystal display device, and in particular to a touch-sensitive liquid crystal display device with electrostatic discharge (ESD) protection function. Background technique [0002] With the development of the industry, digital tools such as mobile phones, personal digital assistants, notebook computers and tablet computers are all developing in a more convenient, multi-functional and beautiful direction. . However, the display screens in mobile phones, personal digital assistants, notebook computers, and tablet computers are indispensable human-machine communication interfaces. The display screens of the above products will bring more convenience to users' operations , where most of the display screens are liquid crystal display devices as the mainstream. [0003] In recent years, with the rapid development and application of information technology, wireless mobile communication and information ...
