Abstract
The invention discloses a manufacturing method of an OLED ultra-thin cover plate, a touch screen and a manufacturing method, wherein, the manufacturing method of an OLED ultra-thin cover plate includes: step 1, loading the evaporated OLED screen into a prefabricated jig, and Preheating the evaporation OLED screen; step 2, loading the evaporation material into the evaporation source, heating to vaporize and decompose the evaporation material, and depositing it on the evaporation OLED in a vacuum environment An evaporated layer of predetermined thickness is formed on the surface of the screen. By adopting the method of evaporation, an evaporation layer with a predetermined thickness is evaporated on the OLED screen as a cover plate, instead of using optical glue to bond the OLED screen, which reduces the process and can be thinned without reducing the strength of the change. The thickness of the product is not limited to the shape of 3D TMP, and various required 3D TMP products can be realized with high yield.
Description
technical field [0001] The invention relates to the technical field of display screens, in particular to a manufacturing method of an OLED ultra-thin cover plate, a touch screen and a manufacturing method. Background technique [0002] With the continuous advancement of technology and the rapid growth of demand in the display field, the cost of displays is getting lower and lower, the usage is bigger and bigger, and the applications are becoming more and more extensive. Existing commonly used display screens include liquid crystal display screens and OLED display screens, wherein OLED display screens are display screens made of organic electroluminescent diodes. Due to the excellent characteristics of self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response, flexible panels, wide operating temperature range, and simple structure and manufacturing process, OLED displays are widely used. Think of it as a next-generation flat p...
