Active array base board for plane display and its repair method

Abstract

The invention is concerned with the initiative array plaque of the plane monitor and its repair method. It includes the plaque with the display section, several of the first and the second electric guiding wires, and several of the first and the second repairing wires set on the plaque separately, the first and the second electric guiding wires are interleaving one with another but without connection, the first and the second repairing wires are interleaving with the second electric guiding wires separately, but connecting the two opposite sides outside the display section with electricity, and also several of the third repairing wires outside the display section and connecting the first and the second repairing wires electrically. The class of second electric guiding wires can form several of the second electric guiding wires group classes and they are opposite any one of the third repairing wires.

Description

technical field [0001] The invention relates to an active array substrate for a flat-panel display and a repair method thereof, in particular to an active array substrate suitable for a liquid crystal display, so as to reduce the probability of "weak line" phenomenon caused by excessive load on the repair circuit. Background technique [0002] FIG. 1A is a schematic diagram of an active array substrate for a flat panel display in the prior art. As shown in FIG. 1A , an active array substrate 1 for a flat panel display in the prior art includes: a substrate 11, a plurality of scanning lines 12, a plurality of data lines 13, a plurality of first repair lines 14, a plurality of second repair lines 15 and A plurality of third repair lines 16. The substrate 11 has a display area 111 on which the scan lines 12 and the data lines 13 are arranged; the scan lines 12 and the data lines 13 intersect in the display area 111 but are not electrically connected to each other. On the othe...

[0004] However, since the first repairing line 14 and the second repairing line 15 intersect with the data line 13 respectively on the upper and lower sides of the display area 111, the first and second repairing lines 14 and 15 will intersect each data line 13, Therefore, when the "repair circuit" is in operation, the load of the "repair circuit" will increase due to the capacitance generated at the intersection of the first and second repair lines 14 and 15 and the data line 13.

Therefore, although the thin film transistor (not shown in the figure) of the pixel located below the gap 132 can be re-operated after the repair process, its reaction speed is slower than that of the thin film transistor (not shown in the figure) of other pixels, resulting in an abnormal picture, that is, the so-called "weak line" phenomenon

[0005] Therefore, the industry needs an active array substrate for a flat panel display and a repair method that can reduce the probability of the "weak line" phenomenon caused by the excessive load of the repaired circuit, so that the display screen of the flat panel display can still be maintained after the repair procedure. It is normal, and the response speed of the screen in some areas is not slow
