Problems solved by technology

[0005] It can be seen from the above that although the existing LCD panel has an electrostatic protection design, the method of guiding static electricity to the VCOM cannot solve the problem of garbled characters on the panel screen due to electrostatic interference, so further review is needed to seek a feasible solution

Embodiment Construction

[0054] Such as figure 1As shown, there is a structural schematic diagram of the first preferred embodiment of the present invention, which is that at least one substrate (10) of a liquid crystal panel is provided with a plurality of drive IC pin pads (11) and soft board connection pads ( 12), wherein the pin pads (11) are electrically connected to each pin of the driver IC (30), and wiring is respectively formed between each pin pad (11) and the corresponding flexible board connection pad (12). 13); make the substrate (10) have a common ground metal layer (20) constituting non-electrical contact on the relative overlapping position of the aforementioned at least one wiring (13), and form a coupling capacitance between the two, and the common ground metal layer (20) is connected to the ground terminal, which means that the aforementioned wiring (13) will form a static discharge path through the coupling capacitor and the ground terminal. When the static surge hits any wiring (...

Abstract

The invention provides a liquid crystal panel with the electrostatic protective effect and a manufacturing method thereof; at least one substrate of the liquid crystal panel is respectively provided with a plurality of driving IC pin pad and a soft sheet connection pad; a wiring is respectively arranged between each pin pad and the corresponding soft sheet connection pad; the substrate is provided with a common-ground metal layer opposite to the wiring so that a static discharge route is respectively formed between the special wiring and the grounding and a surge generated by static influence can be eliminated, therefore, the problem of messy code on the picture caused by static interference can be solved.

Description

technical field [0001] The invention relates to a liquid crystal panel with electrostatic protection effect and its manufacturing method, especially a technology capable of eliminating garbled characters on the screen caused by electrostatic interference. Background technique [0002] Such as Figure 5 Discloses a typical liquid crystal panel control module, which includes a liquid crystal panel (70), a plurality of scanning driver ICs (71) and data driver ICs (72) arranged around the liquid crystal panel (70), one and the aforementioned scanning A frequency driver (73) of the drive IC (71), a frequency controller (74) connected to the aforementioned data drive ICs (72), a VCOM amplifier (75) that provides a stable reference voltage for each pixel in the liquid crystal panel (70) ), a gamma generator (76), a backlight driver module (77), a light sensor (78) and a power supply circuit (79) etc. connected with the aforementioned data driver ICs (72). [0003] Moreover, static...
