Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0024] In the prior art, the cover plate includes a flexible flexible transparent substrate layer and a hardened coating layer, the hardened coating layer is provided on the flexible transparent substrate layer, the flexible transparent substrate layer is used to provide support for the cover plate, and the hardened coating is used for Provide hardness to the cover and ensure the rigidity of the cover. When the cover plate is disposed on the display panel to form the display device, the flexible transparent substrate layer is disp...

Abstract

The invention discloses a cover plate and a display device. The cover plate includes at least one composite film layer, and the composite film layer includes a hardened coating layer and a substrate layer; the hardened coating layer and the substrate layer are stacked and arranged, and the difference between the refractive index of the hardened coating layer and the refractive index of the substrate layer is less than or equal to 0.2, which can be Increasing the reflection angle of total reflection of light from the substrate layer into the hardened coating reduces the probability of total reflection of light. At the same time, the amount of light reflected when the light enters the hardened coating from the substrate layer is reduced, and the amount of refracted light is increased. Therefore, the amount of light entering the hardened coating from the substrate layer can be increased, thereby increasing the light extraction rate of the cover plate and improving the The display effect of the display device.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a cover plate and a display device. Background technique [0002] With the development of display technology, flexible and foldable display devices are becoming increasingly hot. The flexible foldable display device abandons the traditional thick glass cover plate, and uses a flexible flexible transparent substrate and a hardened coating to form the cover plate to meet the cover plate requirements of the flexible foldable display device. In the prior art, the light extraction rate of the cover plate formed by the flexible flexible transparent substrate and the hardened coating is relatively low, which reduces the display effect of the display device. SUMMARY OF THE INVENTION [0003] The invention provides a cover plate and a display device, so as to improve the light extraction rate of the cover plate and improve the display effect of the display d...
