Problems solved by technology

Although these two peeling methods have improved the peeling effect of flexible substrates and rigid substrates to a certain extent through continuous improvement of process conditions, the problems of unclean peeling of amorphous silicon films and germanium oxide films and damage to flexible substrates still remain. Exist, and the process conditions of stripping are also difficult to control, which is not conducive to the production of high-quality flexible displays

Embodiment Construction

[0017] Figure 1A to Figure 1G It is a schematic flow chart of the manufacturing method of the flexible display according to the first embodiment of the present invention. First, see Figure 1A to Figure 1E , which is the manufacturing process of the substrate 100 for the flexible display. In this embodiment, the FOLED display is taken as an example, and the substrate 100 for making the flexible display is shown as a FOLED panel unit. That is to say, the substrate 100 for making the flexible display can finally form an independent flexible display such as a FOLED display.

[0018] see Figure 1A , providing a rigid substrate 110 . In this embodiment, the rigid substrate 110 is, for example, a quartz substrate or a glass substrate, but is not limited thereto. The rigid substrate 110 is mainly used to provide support during the subsequent manufacturing process of circuits and display elements, so as to prevent the flexible substrate from being broken, wrinkled and deformed. ...

Abstract

A method of manufacturing a flexible display includes forming a silicon sacrificial layer on a rigid base material layer, affixing a flexible base material layer to the silicon sacrificial layer by an adhesive layer, forming a display element layer on the flexible base material layer, and utilizing a fluorine-containing corrosive gas to etch and gasify the silicon sacrificial layer to cause the flexible base material layer to separate from the rigid base material layer. A substrate for manufacturing a flexible display includes a rigid base material layer, a silicon sacrificial layer disposed on the rigid base material layer, an adhesive layer disposed on the silicon sacrificial layer, a flexible base material layer disposed on the adhesive layer, and a display element layer disposed on flexible base material layer.

Description

Technical field [0001] The invention relates to a flexible display, and in particular to a method for manufacturing a flexible display and a substrate for manufacturing a flexible display. Background technique [0002] At present, there are many types of display technologies for flexible displays, such as traditional liquid crystal display technology, bistable liquid crystal display technology, organic light-emitting diode (organic light-emitting diode, OLED) display technology, electrophoretic display technology, electrochromism (electrochromism) , EC) display technology and electroluminescence (electroluminescent, EL) display technology. Among them, flexible organic light-emitting diode (FOLED) displays have more advantages than other flexible displays, such as self-luminous display, fast response speed, high brightness, wide viewing angle, and low cost. Moreover, FOLED displays are based on flexible organic materials, which can be rolled, folded, and even used as a part ...
