Problems solved by technology

However, as the number of driving electrodes increases, more second connecting lines need to be arranged to transmit driving signals thereto, but the increase in the number of second connecting lines makes panel wiring more difficult, and each second connecting line There must be corresponding pins to connect to the driving signal, and the design of the driving chip is also difficult to complete the scanning of multiple second connecting lines within one frame.
