Problems solved by technology

However, during the production process of the OLED panel, due to the problem of the laminating process, it is easy to generate fine cracks at the position of the opening of the flexible panel. These cracks lead to the failure of the panel packaging. There will be gradually increasing black clusters and other waste defects

Abstract

The invention relates to an alignment system for detecting a mobile phone screen hole area. The alignment system comprises a first camera assembly, a second camera assembly, a mobile module and a coaxial point light source, the target surface of the first camera assembly faces an area to be detected, and the first camera assembly is mounted on the first mounting plate; the target surface of the second camera assembly faces the to-be-detected area, and the second camera assembly is mounted on the second mounting plate; the first mounting plate and the second mounting plate are both arranged on the moving module, and the moving module drives the first mounting plate and the second mounting plate to get close to each other or get away from each other; coaxial point light sources are installed on the first camera assembly and the second camera assembly. According to the invention, high-precision alignment is carried out on the to-be-detected mobile phone screen, so that subsequent detection is facilitated.

Description

technical field [0001] The invention relates to the field of display panel detection, in particular to an alignment system for detecting the screen hole area of ​​a mobile phone. Background technique [0002] Mobile phone screens are used to display images and colors, and are mainly divided into TFT, TFD, UFB, STN and OLED. [0003] The 2.5D screen refers to the glass that has been specially treated on the display screen. The edge of the ordinary flat glass is curved, but the inner display layer of the screen is still flat. After mobile phone manufacturers adopt 2.5D screens, they shorten the height of the middle frame of the fuselage and make the mobile phone screen protrude outward, creating a visual effect of "water will overflow". Since the concept of 2.5D glass was introduced into mobile phone screens, flat mobile phone screens were classified as 2D screens in the past. The flat structural glass with all points on the glass on the same horizontal plane is collectively...
