Background technique

The LCD display (Liquid Crystal Display, liquid crystal display) market is highly competitive, and all manufacturers strive to improve various performances and strive to maximize performance indicators. In the production and manufacture of LCD, for the consideration of circuit arrangement and structural strength, it is necessary to reserve some non-display areas around the display panel. These non-display areas are an important source of borders for display modules, and major manufacturers strive to reduce the size of the borders. However, due to the product process, it is impossible to completely eliminate the surrounding borders.

One of the important reasons is that TFT-LCD (Thin film transistor liquid crystal display, thin film transistor liquid crystal display) needs to control the gate driver, which is usually arranged on the left edge of the glass substrate of the screen, which has to take up some space. In order to reduce this part of the space, some developers arrange this part of the IC (Integrated Circuit, integrated circuit) at the lower edge of the display screen. Although all the edge space cannot be completely eliminated, the upper, left and right sides can be reduced. However, the accompanying problem is that due to the change of the IC position, the circuit traces in the display screen that control the TFT (Thinfilm transistor, thin film transistor) switch must be adjusted accordingly. The mutated screen wiring affects the display performance of the relevant position, which will cause uneven display.
