Abstract

A cover window (1) for a flexible display device (2) comprises a bendable portion (11) and an unbandable portion (12). The bendable portion (11) has a Young's modulus lower than a Young's modulus of the unbandable portion (12). The bendable portion (11) can pass a bendability test because of the lower Young's modulus while the unbandable portion (12) can pass a pressure test because of the higher Young's modulus. The invention solves a technical problem in the art in which an unbendable portion of a cover window cannot pass a pressure test easily.

Description

technical field [0001] The invention relates to the display field, in particular to a protective cover and a flexible display device. Background technique [0002] In recent years, OLED display technology has been gradually popularized in the mobile phone and TV markets, and the yield rate has been greatly improved. The status of its next-generation display technology is unshakable, and OLED-based flexible display is an important research and development direction of future display technology. [0003] Regardless of whether the flexible screen is curved inward or outward, there is a protective film called a protective cover (Cover Window) on its surface. The purpose is to improve the hardness, scratch resistance and protect the internal film material (such as touch panel or polarizer, etc.). [0004] The cover window is composed of two materials with different Young's modulus. In order to pass the bending test of the bending part in the existing cover window, the Young's mo...
