Embodiment Construction

[0024] In order to further illustrate the technical means adopted by the present invention and its effects, a detailed description is given below in conjunction with the preferred embodiments of the present invention and the accompanying drawings.

[0025] see figure 1 , the present invention first provides a bendable cover plate 10 , which includes at least two non-bending regions 11 and a bending region 12 connecting two adjacent non-bending regions 11 .

[0026] Specifically, a groove 15 is formed on one side surface of the bending area 12 , and the bending area 12 has an arch bridge structure through which the thickness gradually decreases from the two sides close to the non-bending area 11 toward the center through the groove 15 . , which can effectively enhance its own bending ability.

[0027] Specifically, the bendable cover plate 10 is a glass plate that has undergone doping treatment and laser treatment, thereby changing the original material structure and propertie...

Abstract

The invention provides a bendable cover plate and a flexible display device. According to the bendable cover plate, a groove is formed in a corresponding bending area, so that the bending area is of an arch bridge structure, and accordingly the bending capacity can be effectively improved; by adopting a glass plate material subjected to doping and laser processing, the original structure and property of the glass material are changed, the surface rigidity can be greatly improved, the bending capacity and surface rigidity of the flexible display device can be correspondingly improved, the bending capacity of the flexible display device is improved, and meanwhile the touch demand of a client is met.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a bendable cover plate and a flexible display device. Background technique [0002] Organic Light Emitting Diode (OLED) displays have self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast ratio, nearly 180° viewing angle, and wide operating temperature range, which can realize flexible display With many advantages such as large-area full-color display, it is recognized by the industry as the most promising display device. At present, OLED technology is more and more widely used in mobile phones, digital cameras, notebook computers, TVs and other products. Among them, flexible OLED (Flexible OLED) technology has received extensive attention, and the advantage of this technology is that it can realize a bendable OLED display device. Consumers are concerned about whether these new mobile devices are well d...
