Embodiment Construction

[0041] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0042] The present invention firstly provides a COA type liquid crystal display panel structure. The so-called COA type liquid crystal display panel adopts COA (Color Filter On Array) technology, and the color filter is integrated and manufactured on one side of the TFT array substrate, which can increase the aperture ratio of the liquid crystal display panel. , to reduce the effect of parasitic capacitance.

[0043] Please also see figure 2 and image 3 , The COA liquid crystal display panel structure of the present invention includes a display area A and a peripheral area K outside the display area A. According to the order from near to far from the display area A, the peripheral area B includes an electrostatic protection area K2, a GOA ...

Abstract

The invention provides a COA type liquid crystal display panel structure and a manufacturing method of a COA type liquid crystal display panel structure. The COA type liquid crystal display panel structure sets a color barrier layer (7) in the GOA circuit region (K1) of a peripheral zone (K) and sets a common voltage line (9) above the color barrier (7), the existing the common voltage line paralleling to the GOA circuit region in the peripheral zone of the existing liquid crystal display panel is moved to the top of the GOA circuit, so that the common voltage line no longer occupies the widthof the display border, so that the border width of LCD panel can be reduced which helps to realize the narrow borders of LCD panel products.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a COA type liquid crystal display panel structure and a manufacturing method of the COA type liquid crystal display panel. Background technique [0002] With the development of display technology, liquid crystal display panels (Liquid Crystal Display, LCD) are widely used in mobile phones, TVs, personal digital assistants, Various consumer electronic products such as digital cameras, notebook computers, and desktop computers have become mainstream products in display devices. [0003] Generally, a liquid crystal display panel is composed of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. The rotation of the liquid crystal molecules in the liquid crystal layer is controlled by applying a driving vol...
