General reasons for Lines on Screen:
a. COF problem
b. Glass circuit problem: short circuit, open circuit.
c. Power problem – By PASS ,Jumper etc
d. PCB board problem
- Bonding machine can only solve a. COF problem;
- Laser machine can solve b problem,
- Some times laser machine can also solve a, c,d problem (If just very few lines).
Glass Simple Structure
Each pixel is composited with RGB 3 original colors. Each color brightness is controlled by one COF line.
Principle of Laser machine
The principle of laser machine repairing is using the power of laser to change the circuit connection in glass.
Have two function
1. Break a wire 2. Connect two wires
In glass usually have some spare wires for repairing.
In normal condition, there is a insulating layer between main wire and spare wire, main wire and spare wire is not connected.
If apply a proper laser pulse to the cross, can break the insulating layer, and the main wire and spare wire be connected.
Case 1: Repair a Open Circuit
Case 2: Repair a Short Circuit
