The bright spots on the mobile phone screen are common problems, and they generally follow the national quality standards for LCD displays and will not be replaced within 3 points. For details, you can consult Coolpad after-sales service.

The crystal surface of the LCD screen is a monolithically cut lens, and if there is a slight vibration or dust falling into the crystal structure during processing, then this bright spot will be produced and cannot be repaired. The bright spots are mostly light blue and red, sometimes white, and a few green. It has to do with the ingredients of the highlights.

Usually LCD screens also have the term dead pixels. Bad pixel refers to the crystal lattice that cannot produce changes in crystal structure and cannot produce light in the shed, that is, it cannot emit any light and is black.

About the introduction and guess of the highlight restoration.

However, the mountain should remind me that these methods are still more suitable for products that have passed the warranty period or are not returned by the manufacturer.
