Problems solved by technology

[0005] For the first Samsung solution, the main disadvantage is that after the CPI as the protective layer of the OLED layer is added with a hardening film, although it can be bent, there will be creases after bending, which is very unfavorable for folding screens.
For the second solution, because a layer of PET is added and an additional layer of OCA is required, the thickness increases a lot, and CPI is also used, which will cause creases
[0006] The applicant's previous application 202010098015.1 records a structure and manufacturing method of a foldable AMOLED display. In this invention, the touch sensing layer is made on the ultra-thin glass. During the experiment, it is found that the ultra-thin glass is slightly less resistant weak

Abstract

The invention discloses a structure of an explosion-proof foldable AMOLED display screen. The structure of the explosion-proof foldable AMOLED display screen sequentially comprises a PI substrate, a circuit driving layer and an OLED layer from bottom to top, a plurality of thin film packaging layers are arranged above the OLED layer; and an ultra-thin glass layer is attached to the upper portion of the multi-layer thin film packaging layer. The ultra-thin glass layer comprises ultra-thin glass and an explosion-proof film on the surface of the ultra-thin glass; a circular polarizer is attachedto the upper portion of the ultra-thin glass layer. A PET layer with a touch sensor is attached to the upper portion of the circular polarizer. According to the AMOLED display screen, the whole AMOLEDdisplay screen can be folded without folding marks when being bent, the whole AMOLED display screen is thinner, bending is facilitated, the ultrathin glass is effectively protected through the explosion-proof film, and the explosion-proof function is achieved.

Description

technical field [0001] The invention belongs to the field of OLED display screens, and more specifically relates to a structure and a manufacturing method of an explosion-proof foldable AMOLED display screen. Background technique [0002] Since the beginning of 2019, companies including BOE have successively exposed fully self-developed foldable self-illuminating flexible screens. According to network news, Samsung, Huawei, and other companies have also made related products. China Unicom even stated in the official Weibo that "folding screen mobile phones are not far away!" [0003] At present, there are many problems with the folding screen mobile phones released on the market. For example, Samsung’s Galaxy Fold has just released the test machine, and there are various problems on the screen. [0004] In addition to the fact that the flexible OLED display panel of a folding screen mobile phone must be foldable, in the entire mobile phone display, there must be some other...
