Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a processing technology of an electronic screen. Background technique [0002] Due to its high hardness (hardness of 9 is second only to diamonds), wear resistance, and high transmittance, sapphire has been gradually used in mobile phone camera protection covers, mobile phone fingerprint sensor buttons and mobile phone touch screen covers. The sapphire material is a single crystal with crystal orientation, and different crystal orientations have different physical and chemical properties. The crystal direction of sapphire includes C direction, A direction and R direction, etc. The plane perpendicular to the crystal direction is called C plane, A plane and R plane correspondingly. [0003] At present, the working surfaces of sapphire components used in the electronic product industry mainly use the A and C surfaces of the crystal. The theoretical bending strength of ...
