We are in the process of maintenance.We often deal with screen changing jobs.
In our screen changing job.We often pay attention to several principles:

1.Dimensional consistency:Same size

2.The panel resolution is consistent.There are two general resolutions:
 A :Standard resolution is 1360*768
 B:Full HD screen is 1920*1080
The two are distinguished at the logic board signal interface.
The software versions of the two are also quite different.It can not be replaced directly.
So we need comfirm the resolution.

3.Screen power consistent:The voltage values are 3.3V.5V.12V.18V ect.
If the power supply does not match.It is likely to cause a screen or burn.

4.The signal interface type is the same:The general interface type is TTL.LVDS.TMDS.RSDS.
