Abstract

The invention provides a display module, a preparation method and a display device. The preparation method of the display module comprises the following steps: providing a display panel, wherein the display panel comprises substrate glass, a driving circuit layer, a light-emitting function layer and a packaging layer; attaching a back plate to the packaging layer; thinning the substrate glass, and thinning the substrate glass to a preset thickness to form the ultrathin glass. The substrate glass is processed to obtain the ultrathin glass, a conventional PI flexible film layer supporting panel is replaced, the substrate glass and the PI flexible film layer do not need to be separated through a laser stripping process, and the problems that according to an existing flexible OLED display screen manufacturing process, the substrate glass needs to be stripped through lasers, and the effect is poor are solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module, a manufacturing method and a display device. Background technique [0002] Flexible organic light emitting diode (Organic Light Emitting Diode, OLED) display has the advantages of active light emission, large viewing angle, wide color gamut, high brightness, fast response, low power consumption, and flexible and foldable structure. increasingly popular in the market. Utilizing the bendable and foldable characteristics of the flexible OLED display, various forms of foldable display devices can be prepared, which are convenient to carry and store when going out. [0003] With the development and maturity of flexible OLED display manufacturing technology, the current manufacturing process of flexible OLED display generally includes: using substrate glass as the substrate, coating PI (Polyimide, polyimide) flexible film on the substrate glass layer, and then fabr...
