Step 1: Prepare 5 or 7-inch defective products that need to be disassembled (Note: Pay attention to the surface and environment before assembly to avoid dust or dirt from contaminating the touch screen and display)
Step 2: Disassemble the cable of the touch screen: 1 first tear off the yellow high-temperature glue on the cable pad; if there is no sticker, then ignore it. 2 Use tweezers or other tools to wire the touch screen cable from the display.

Technical point 2:
1. When the knife edge is swiped, be sure not to scratch or double-sided tape to contaminate the display.
2. When the knife edge is swiped for a distance or when changing direction, be sure to isolate the touch screen with a hard object to prevent the touch screen from sticking to the display.
3. The hard object used for isolation should be clean. It is not necessary to go deep into the display screen when it is isolated. It can isolate the touch screen.
Key point: When the knife edge slides, you must control the rhythm, speed, distance, don’t worry, the action should be slow, don’t break the touch screen, because the touch screen is broken, its small debris is easy to fall on the display, it is more difficult to clean up, The most likely to hurt/stain the display.
