Light ：LTS-COX60-W
The scratches on the screen surface are relatively minor, and the glass surface is relatively smooth. Using a coaxial light can inspect the scratches, and the scratched areas can have a high contrast.
Bubble inspection of the middle film on the screen
Light ：LTS-4COXL220-B
There will be bubbles when the middle film of the screen is adhered. Using coaxial light can better highlight the bubbles. Blue can effectively enhance the contrast of the effect and is more conducive to image processing.
Inspection of electroplating circuits on the glass screen
Light：LTS-3SL083-W
For the electroplating circuits on the screen, they cannot be seen under normal conditions. By using point light with a coaxial teleconsteric mirror, the circuits can be clearly seen under high vertical illumination.
Foreign object detection in the screen display layer
Light：LTS-4BR25030-W
There are foreign objects, notches and multiple materials in the screen display layer. Defects are inspected inside the film. The interference of the film needs to be taken into account. Four combined strips of light are used to highlight the defect location, and low-angle light is used to eliminate other interference.
