Window protective glass and manufacturing method

Abstract

The invention provides a window protective glass, which comprises a cover plate, a printing ink layer, a polarizer layer, a compensation film layer and an optical adhesive layer. The invention further provides a manufacturing method, which comprises the steps of: arranging the polarizer layer in a visible region of the cover plate; arranging the compensation film layer on the polarizer layer; arranging a first optical adhesive layer on the compensation film layer; arranging the printing ink layer outside the visible region on one side surface, on which the polarizer layer is arranged, of the cover plate; and arranging a second optical adhesive layer on the printing ink layer. Compared with the prior art, the printing ink layer is arranged on the periphery of one side of the cover plate, and the polarizer layer, the compensation film layer and the optical adhesive layer positioned in the visible region of the cover plate are arranged within the printing ink layer, thereby avoiding the occurrence of the problem of thickness difference between the printing ink layer and the cover plate, and preventing the problem of corrugation which occurs in bending.

Description

technical field [0001] The invention relates to a display technology, in particular to a window protective glass for flexible organic light-emitting devices and a manufacturing method. Background technique [0002] Organic light-emitting (OLED) devices (OLED) have self-illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, and relatively simple structure and manufacturing process And other excellent characteristics, it is considered to be the new application technology of the next generation flat panel display. [0003] The structure of an OLED device is composed of an anode (ITO), a cathode, and an organic functional layer sandwiched between them. The organic functional layers include HIL, HTL, EML, ETL and other layers. [0004] The existing cover plates with ink layer (INK) all have thickness differences. The thickness of the black ink layer is generally 10-15...

AI Technical Summary

Problems solved by technology

[0004] The existing cover plates with ink layer (INK) all have thickness differences. The thickness of the black ink layer is generally 10-15um, and the thickness of the white ink layer is generally 15-20um. However, foldable products have higher requirements on the thickness of the cover plate. After thick bending, severe waviness will be generated, which cannot meet the requirements of flexible display screens
