Problems solved by technology

Increasing the number of data lines, if the length of the data lines is too long will cause display problems such as signal delay; if the line width of the data lines is increased in order to reduce the signal delay, the aperture ratio of the pixel area will decrease, and at the edge of the data lines Also prone to defects that affect display performance
