Problems solved by technology

In order to avoid the short circuit of the gate shift register 050 caused by the contact between the gold ball 040 and the gate shift register 050 arranged on the side of the lower substrate 020 facing the upper substrate 010, it is required that the gate shift register 050 and the sealing frame containing the gold ball 040 Adhesive 030 must maintain a certain safety distance. This safe distance must at least be guaranteed to be greater than the coating accuracy of sealant 030 to meet the coating requirements of sealant 030. Therefore, it is difficult to realize the narrow frame design of TN-type LCD panels.
