Embodiment Construction

[0041] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0042] The present invention aims at the existing COA substrate, where the parasitic capacitance value at the intersection of the gate line and the data line is relatively high, which increases the signal delay, reduces the effective charging time of the pixel, and further affects the technical problems of the display effect of the liquid crystal display panel. can sol...

Abstract

The invention provides a COA (color filter on array) substrate, comprising a thin-film transistor array, data lines, scanning lines, pixel electrodes and common electrodes; the data lines and the scanning lines interact to define pixel units, the intersections of the data lines above the scanning lines form gaps which cross the scanning lines, two ends of each gap are connected through a jumper, and the jumpers are communicated with the data lines through second via holes. The COA substrate has the advantages that the parts of the data lines overlapping the scanning lines form the gaps, the jumps are added to the top of the substrate to connect the gaps of the data lines, the thickness of the jumpers from the film layer of the scanning lines is increased, parasitic capacitance of overlap portions is reduced, signal delay is decreased, effective charge time of the pixels is extended, and accordingly the display effect of a liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a COA substrate and a liquid crystal display panel with the COA substrate. Background technique [0002] Display devices such as Liquid Crystal Display (LCD for short) and Organic electroluminescent device (OLED for short) have become necessities in people's lives. With the improvement of people's needs, in order to improve the display quality of display devices To avoid the deviation of the array substrate and the color filter substrate when the box is aligned, affecting the aperture ratio of the display device and the problem of light leakage, the integrated technology (Color Filter on Array, COA for short) that integrates the color filter and the array substrate is born. The COA technology is to arrange the color filter on the array substrate. [0003] As the pixel density of the panel becomes higher and higher, the scanning lines of the pixels will also increa...
