Problems solved by technology

However, there is also a risk of a short circuit between the pixel electrode 106 and the storage capacitor electrode 120
[0007] Therefore, the pixel structure in which the shared electrode is arranged under the signal line cannot be repaired immediately on the storage capacitor electrode by laser cutting, so that the display panel can only be scrapped, resulting in waste of cost

Abstract

The invention discloses a repairing structure and a repairing method for a liquid-crystal display (LCD) panel. The LCD panel is provided with a plurality of shared wirings and a plurality of scanning lines, wherein the shared wirings are parallel to the scanning lines, and the shared wirings and the scanning lines are alternately arranged on a base plate; each shared wiring is provided with a plurality of branches and a plurality of notches; the plurality of branches are parallel to a plurality of signal lines, and are overlapped but separated from the signal lines; and each branch, the corresponding signal line and a pixel electrode are configured to enable the corresponding notch to be exposed, so that an external tool can be provided to cut off the shared wiring from the notch, thereby disconnecting the shared wiring and the branch.

Description

technical field [0001] The present invention is related to the repair structure in the liquid crystal display (TFT-LCD), in particular to a repair structure and repair method of a liquid crystal display panel with a high aperture rate (Aperture rate). Background technique [0002] Liquid Crystal Display (LCD) has been widely used due to its advantages of low radiation, thinness, lightness and small size, and has become the mainstream display in the market. [0003] Since the liquid crystal itself does not emit light, the liquid crystal display needs to use a backlight module as a light source. The light source penetrates through various layers of the liquid crystal display, such as polarizers, color filters, etc. About ten percent of the light source. Also because of insufficient display brightness, if the brightness of the backlight module is increased, although the brightness of the panel can be increased, the power consumption of the backlight module is also increased. ...
