Circular track type cell cutting system for manufacturing flexible OLED (Organic Light Emitting Diode) display panel

Abstract

The invention relates to the technical field of display screens. According to the technical scheme of the invention, a circular track type cell cutting system for manufacturing a flexible OLED (Organic Light Emitting Diode) display panel comprises an annular guide rail and a plurality of positioning jigs arranged on the annular guide rail, wherein a CO2 laser cutting station, a protective film tearing-off station, an UV (ultraviolet) laser cutting station, an IR (infrared) laser cutting station, a splinter station and a discharging station are arranged on the annular guide rail. The circular track type cell cutting system integrates the tearing-off of protective films and the cutting of an OLED display panel master slice with a glass substrate for the first time, and has high degree of automation, high cutting efficiency and high precision.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a ring-track box-forming and cutting system for manufacturing flexible OLED display panels. Background technique [0002] The rapid development of modern electronic technology, especially the display technology, from the mature LCD to the more and more widely used OLED, has now developed into a flexible and bendable OLED display panel, and the preparation of the flexible OLED display panel is the same as that of ordinary OLED displays. The panels are very different, the difficulty of production is high, and the process is also very different from ordinary OLED display panels. [0003] The production of flexible OLED display panels is to make multiple pieces of flexible OLED display panels together on a large glass substrate. At this time, it is generally called a master piece. Followed by laser stripping glass process. The process of cutting the mother chip into single ...

AI Technical Summary

Problems solved by technology

[0005] At present, the mainstream production line has entered the sixth generation (the size of the glass substrate is 1500mm x 1850mm), and even a quarter of it needs to be 750mm x 925mm. The current box cutting is a single process using laser cutting, and the flexible OLED display panel mother After the chip is made, there are several intermediate processes before the box cutting, and the size of the mother chip is relatively large, so it is very inconvenient to handle, and it is easy to be damaged during transportation, resulting in a relatively low box cutting efficiency
