Problems solved by technology
[0003] In the development process of DF OLED display, it is necessary to replace the traditional rigid cover glass (Cover Glass, CG) (thickness 500-600μm) with non-rigid bendable CG (thickness 50-100μm), but due to the The thickness of the bent CG is relatively thin, and micro-cracks are prone to occur at the edges, and the extension of the micro-cracks can easily cause the entire piece of bendable CG to break, resulting in a low yield rate of DF OLED displays

The invention discloses cover plate glass and a display device with the cover plate glass. The cover plate glass comprises a first section, a second section and a third section, the first section andthe third section are respectively and gently connected with two opposite ends of the second section. The thickness of the first section is gradually increased in the direction from the end connectedwith the second section to the end away from the second section. The thickness of the third section is gradually increased in the direction from the end connected with the second section to the end away from the second section. The thicknesses of the first section and the third section of the cover plate glass are set to be gradually increased from the junction of the first section and the secondsection to the edge of the cover plate glass; when the cover plate glass is applied to the display device, the first section and the third section are arranged to be non-bent sections of the cover plate glass, and due to the fact that the thickness of the non-bent sections of the cover plate glass is increased, the risk that microcracks at the edge of the cover plate glass extend towards the interior of the cover plate glass is reduced, and the yield of the display device is increased.
Description
technical field [0001] The present application relates to the field of display technology, in particular to the field of manufacturing technology of display devices, and in particular to a cover glass and a display device having the cover glass. Background technique [0002] In recent years, flat panel displays such as Liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) displays have gradually replaced cathode ray tube (CathodeRay Tube, CRT) displays and become mainstream products in the display market. . Among them, due to the advantages of wide viewing angle, high color gamut and low power consumption, OLED display is recognized by the industry as the display with the most development potential, and the development of dynamic foldable (Dynamic Foldable, DF) OLED display has gradually become an industry development trend. The goal. [0003] In the development process of DF OLED display, it is necessary to replace the traditional rigid cover glass (Cover G...
