Problems solved by technology

[0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current flat-panel display market. The actual production Due to factors such as metal residues and foreign objects, the channel of the thin film transistor may be short-circuited, causing it to lose its switching function, resulting in the pixel being displayed as a bright spot. At this time, it is usually necessary to darken the pixel. The wire is short-circuited with the pixel electrode, so that the pixel electrode has a common voltage, so that the voltage difference between the pixel electrode and the common electrode on the side of the color filter substrate is zero, and the electric field is zero, so that the liquid crystal is not deflected, the light cannot pass through, and the pixel is darkened; At present, there are some displays, in order to increase the pixel aperture ratio, the display structure of the gate storage capacitor structure is adopted, that is, the common line is not provided on the array substrate side, and the storage capacitor is formed by partially overlapping the pixel electrode and the gate line.
[0003] However, in such a storage capacitor design, the pixel electrode directly overlaps with the next row of scan lines to form a storage capacitor. Therefore, when the pixel is abnormal, it is impossible to short-circuit the pixel electrode and the common line to achieve dark spots, which seriously reduces the Product yield rate and pixel repair rate
