LCD SCREEN LASER REPAIR MACHINE
LCD Panel Repair Laser Machine
LCD laser repair machine (referred to as laser machine) on the LCD screen repair industry
accounted for the high-end repair technology, the most high-end technology of LCD screen repair, LCD screen repair industry in addition to the COF loose welding, TAB char (This error can be repaired with a binding machine) Others such as ITO break, short line, bright line, half-line, dotted line, a multi-line laser machine can be used to repair. Laser machine with high efficiency, fixed rate, low cost (the same fault in the laser machine does not need replacement parts, (and do not affect the repair rate), it is widely used as the main device screen repair of large-scale production factory, after sale and service company.
Laser repair purposes, is hoping to further the defective part to be corrected, so that the original
filter out waste products to be discarded, repair to an acceptable product. The current acceptable
product standards—-Firstly is definitely not wired defects; secondly, many products are “no highlights assurance”. So the pixel cannot have been glowing are bright spots, but to some extent accepted few dark spots. Therefore, the object of laser repair, based on the main line defect and highlights.
This “LCD Panel Repair Laser Machine” is equipped state of art control system from research and
development including Laser Head ( HOYA Laser Controller), using MITUTOYO precision optical imaging system (laser processing / observing special microscope, laser processing special optical lens, image observation objective lens), X / Y / Z motor drive system, Electronic control systems, Gas pressure cushioning system, Composed of precision steel base and other .This equipment can be given work piece material layer for short-circuit defect repair process. Work piece to use manual mode.

How Laser Machine Work
The most frequently asked question is what are the faults which can be repaired by a laser machine?
The principle of laser machine is for LCD LED screen inside circuit repairing, that means almost all faults which caused by screen inside circuit are can repaired by a laser machine. And laser machine also can repair some COF/TAB faults (instead of bonding machine).
Laser LCD Repair Machine Introduction:-
- Each Pixel is composited with 3 RGB original colors.
- Each color brightness is controlled by one COF line
LCD 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 functions:
1. Break a wire
2. Connect two wires
Beak a wire
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 will be connected.
Case 1: Repairing a open circuit
Solution: Connect to the same color wire
Case 1: Repair a open circuit
Step 1: Cut spare wire
Case 1: Repair a open circuit
Step 2: Connect main wire and spare wire
Now line 1 is connected to line 2, line will display same as line 2.
Though line 1 display is a little different from the original image, but can not be distinguished by eye.
Case 2: Repair a short circuit
Short circuit between two wires, just cut it with the laser.
Case 3: Repair a pixel
For a broken pixel, just cut the power supply of this pixel, then the the pixel will become dark, and can not be saw by eye.
Case 4: Case share
User laser machine to repair a vertical line on LCD LED screen
Case 5: COF problem repaired by laser machine
When come with a COF wire broken problem:
1. Change a new COF
2. Repair as Case 1
Method 1 advantage:
Perfect display after repairing
Method 2 advantage:
a. Fast repairing
b. No need consumable material, low cost.
