Embodiment Construction

[0017] see figure 1 The display panel according to the first embodiment of the present invention includes an array substrate 100 , and the array substrate 100 includes a plurality of gate lines 110 and a plurality of data lines 120 insulated from and intersecting with the gate lines 110 . The data lines 120 and the gate lines 110 enclose a plurality of pixel areas P, and the minimum area formed by the intersection of the data lines 120 and the gate lines 110 defines a pixel area P. Each pixel region P includes a pixel electrode 130 and a thin film transistor (TFT) 131 connected to the pixel electrode 130 as a switching element. The plurality of pixel regions P constitute a display region D of the display panel.

[0018] The array substrate 100 of the display panel further includes a gate line repair circuit (not shown in the figure), and the gate repair circuit includes a plurality of gate switches 211 and repair lines. The repair line is set outside the display area D and s...

Abstract

A display panel comprises an array substrate, wherein the array substrate comprises an insulation base, multiple grid lines, multiple data lines, a grid repairing circuit and a scanning driver used for providing a scanning signal for the multiple grid lines. The grid repairing circuit comprises multiple grid switches and a repairing line, wherein the multiple grid switches and the multiple grid lines are electrically and correspondingly connected, the repairing line comprises three parts surrounding three lateral edges of the display area of the display panel and is used for transmitting the scanning signal output by the scanning driver to one end of a broken grid line to the other end of the broken grid line under the condition of grid line breaking, one or two parts of the three parts constituting the repairing line are formed by patterning of a first conductive material layer on the insulation base, and the rest parts are formed by patterning of a second conductive material layer. Due to the fact that the repairing line is arranged on the periphery of the display area, pollution to a pixel unit during grind line repairing can be avoided, and the manufacturing technology can be simplified at the same time.

Description

technical field [0001] The invention relates to a display panel, and in particular to a display panel with a gate line repair circuit. Background technique [0002] A liquid crystal display (LCD) has an upper substrate (also called a color filter substrate) and a lower substrate (also called an array substrate). The color filter substrate includes a plurality of common electrodes. The array substrate includes a plurality of gate lines, a plurality of data lines, a plurality of pixel electrodes and a plurality of thin film transistors. The gate lines are arranged along the first direction at regular intervals. The data lines are arranged at regular intervals along a second direction perpendicular to the first direction. The plurality of pixel electrodes are arranged in a matrix structure in a pixel area defined by intersecting gate lines and data lines. The thin film transistors can transmit data signals from the data lines to the pixel electrodes according to the scannin...
