DISPLAY SCREEN GROOVING METHOD AND DISPLAY SCREEN

WIPO Patent Application WO/2019/205466

A1

A display screen (100) grooving method and a display screen (100). The display screen (100) grooving method comprises the following steps: subtractively processing the display screen (100) such that the display screen (100) forms a first mounting groove (120), two adjacent side surfaces in the first mounting groove (120) being connected by means of a first curved transition surface (122); subtractively processing the first mounting groove (120) so as to form a second mounting groove (140), two adjacent side surfaces of the second mounting groove (140) being connected by means of a second curved transition surface (142); the display screen (100) comprises an oppositely disposed upper surface (110) and lower surface, the first mounting groove (120) and the second mounting groove (140) penetrating the upper surface (110) and lower surface, and the radius of curvature of an orthographic projection of the second curved transition surface (142) on the plane on which the upper surface (110) is located being smaller than the radius of curvature of an orthographic projection of the first curved transition surface (122) on the plane at which the upper surface (110) is located. The described display screen grooving method reduces processing equipment requirements and processing difficulty, and improves cutting precision and yield rate for a display screen (100).
