Bending jig

Abstract

The invention relates to the field of manufacturing of liquid crystal displayers, in particular to a bending jig. The bending jig is used for making the display area of a flexible OLED screen and an outer lead bonding attachment area bent and attached, and comprises a bearing table, a turnover plate, a line pressing plate and observers. The bearing table is connected with the turnover plate through a rotary shaft, a first containing cavity and a second containing cavity are formed in the bearing table and the turnover plate respectively, and the first containing cavity and the second containing cavity are matched to form a containing area which is used for containing the flexible OLED screen. The rotary shaft drives the turnover plate to be overturned towards the bearing table and attachedto the bearing table, sucking discs or air holes are arranged on or formed in the surface, making contact with the flexible OLED screen, of the containing area and used for sucking and fixing the flexible OLED screen. In the bending jig, a negative pressure suction sample is adopted, and the consistency of bending positions is ensured by using the line pressing plate, so that the bending technology is high in efficiency and yield.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacture, in particular to a bending process of a flexible OLED screen. Background technique [0002] With the development of the mobile communication field, major mobile terminal equipment manufacturers have increasingly strong demands for mobile terminal equipment with a high screen-to-body ratio, and mobile terminals are gradually entering the era of full screens. Traditional LCD screens are difficult to further increase the screen-to-body ratio due to their own technical limitations, but with the emergence of flexible OLED screens, full screens have become possible. [0003] In view of the flexible nature of the flexible OLED screen, during the production process, the outer pin bonding area of ​​the screen can be folded under the display area of ​​the screen, so that the frame of the display area can be reduced, or even reduced to zero. Since the outer pin bonding area is usually set ...

AI Technical Summary

Problems solved by technology

[0004] At present, the technology of folding the outer pin bonding area under the flexible OLED screen to the back of the screen display area can be referred to as the screen bending technology for short. This technology is still a new processing topic, and the process is difficult. It is also relatively low, and there is currently a lack of mature special bending equipment on the market to correspond to it. Therefore, it is necessary to design a special fixture for screen bending to correspond to this emerging process.
