You can try the oil with hands-on ability, and the screen scrapping has nothing to do with me.
Modification method: first remove the screen and make it into a bare screen, with the model on the back of the screen. After getting the model, go online to find the screen parameters.
It mainly depends on what interface your screen is, what driver board you need (mainly to get the driver number and then write it), sequence, and what kind of high-voltage bar (the choice of high-voltage bar depends on whether your lamp is a single-port small lamp or a dual-port small lamp). The most important thing is the screen drive line. If you buy the wrong screen driver cable, then your screen will be goodbye.
You can go to Taobao to buy a suit and tell JS the model of your screen, and he will help you finish it all. Just go home and assemble it at last.
PS pay attention to the high-voltage board, and don't touch it when it is energized, otherwise it will smell like burnt pig's feet at home.
