LCD what waste products can be detected by the LCD screen?

Do you know what scrap products can be detected by LCD LCD screens? Today for the specific analysis of everyone, I hope to help you.

 1. box

 Under the dark field (or bright field) there are white (or blue and black) spots appear, which is caused by the dirt inside the liquid crystal box, commonly known as internal dirt. The reason for its formation is that before the glass bonding, the glass surface attached with foreign bodies or powder spraying process powder did not spread out.

 2. fingerprinting

 LCD LCD screen has fingerprint marks in the 3.5 small tft lcd visual observation display area, which is left by the operator's fingers touching the iTO and PI surfaces of the glass before the glass fit.

 3. orientation error/difference

 When the dark field (or bright field) is not observed in visual measurement, this is the trace left by the operator's fingers touching the ITO and PI surfaces of the glass before the glass fits.

 4. border deformation

 Visual inspection found that the width of the border with uneven image called border deformation.
 
 5. Rainbow

 LCD the LCD screen in visual observation of the ring or ribbon uneven color is known as a rainbow.

 6. bubbles

 Bubble refers to LCD liquid crystal screen in the visual process found that the liquid crystal box is not completely filled with liquid crystal, can still see the appearance of bubbles. This is mainly due to errors in the process of pouring liquid crystal.

 7. air leakage

 In the visual table, if a small amount of gas is observed at the seal of the liquid crystal box into the box or the seal is not sealed, the present image is called air leakage.

 8. poor cutting

 Poor cutting is the appearance of irregular glass edges caused by improper cutting or grain breaking.
