LCD screen laser repair machine
Product application；
Mainly in the mirror through the high frequency pulse laser beam of the LCD internal semiconductor circuit of the micron size of cutting and trim especially passivation layer (silicon oxide / nitride) and metal interconnection to achieve the role of line maintenance, the device can adjust the laser pulse energy and wavelength for different target materials.
Equipment use
It is mainly caused by the internal line defects of the LCD screen, including LCD screen highlights, vertical line, horizontal line, cross line, half line, black screen, gray screen, screen thickness, picture jitter, uneven display, and a series of screen and internal line problems of the screen substrate.
