Why does this screen occasionally go black when turned on, and sometimes it displays normally when turned on?I can't find what's wrong.
A: It's a question of setting up the power-on timing.Need to check IC specification to write time sequence according to requirements, optimize the delay.Also can write the second initialization at the same time sent to the motherboard, the first initialization failed, the second will be initialized again, and the second certain initialization is successful, mainly is the mainboard voltage and IC voltage exist range value, the second initialization played a strengthening role.
