Problems solved by technology

However, because digging and slotting of the display screen requires cutting in the display area of ​​the display screen, mechanical cutting or laser cutting is generally used for cutting the display screen in the prior art, and layered cutting along the edge area of ​​the special-shaped opening/groove shape , this cutting method has the following defects: (1) The special-shaped cutting track is close to the display area, and the concentration of thermal stress will cause the material at the edge of the displ

Abstract

The invention discloses a display screen and a cutting method thereof. The display screen is provided with a protecting structure along a cutting area edge of the display screen; the protecting structure covers the side wall of the cutting area edge, is a multi-layer structure and can effectively protect a trepanning area edge and a grooving area edge of the display screen, thus the stress is hierarchically buffered and dispersed, impact force is neutralized stage by stage, the anti-collision capacity of a trepanning area and a grooving area of the display screen is improved, and the overall strength of the display screen is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen, especially an OLED display screen and a cutting method thereof. Background technique [0002] With the advent of the full-screen era, various display forms are blooming. At present, the mainstream full-screen forms that are most accepted by the market include notch screens, water drop screens, and hole-digging screens; A relatively broad definition of mobile phone design, literally means that the front of the mobile phone is all screens. Due to the limitations of current technology, the full-screen mobile phones announced by the industry are only mobile phones with ultra-high screen ratio for the time being. Organic Light Emitting Diode (OLED) technology is a new type of display technology, which is commonly used in mobile phone display screens. [0003] In order to realize full-screen display, it is necessary to dig holes and slots in the display area of ​​t...
