Embodiment Construction

[0018] First, the definitions of two technical terms are given.

[0019] The "viewing angle" refers to the angle formed by the line of sight of the human eye and the vertical direction of the display surface.

[0020] "Exit angle of light" refers to the angle formed by the light emitted by a light-emitting element, such as a light-emitting diode, and the vertical direction of the display surface.

[0021] As mentioned in the background art, the brightness of common display products with anti-privacy function (hereinafter referred to as anti-privacy display products) is relatively low. Specifically, common anti-peep display products are usually realized based on the principle of shutters, that is, the light emitted by the light-emitting element is blocked when it hits the blades of the shutter, and can pass through when it hits the gap between the blades, so as to realize display with a narrow viewing angle. , so as to realize the privacy protection function. The shaded part ...

Abstract

The invention provides a display panel and a display device. The problem that in the prior art, a display product with a peep-proof function is low in brightness is solved. The display panel comprises a light-emitting element which is provided with a light-emitting surface; the pixel definition layer surrounds the light-emitting element to form a pixel opening exposing the light-emitting surface; a first microlens covering the pixel opening; the second micro lens is arranged on the side, away from the light-emitting element, of the first micro lens; wherein light rays emitted by the light-emitting element comprise first light rays and second light rays, the emergent angle of the first light rays is larger than that of the second light rays, and the emergent angle refers to the included angle between the light rays and the vertical direction of the light-emitting surface; the first light is totally reflected in the first micro lens, and the second light enters the second micro lens after being emitted from the first micro lens and is converged by the second micro lens.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In recent years, with the development of the display industry, different application scenarios have different functional requirements for display products. Among them, privacy protection is a major demand in the current market. However, common display products with an anti-privacy function often lead to a decrease in display brightness while achieving the anti-privacy effect, which affects user experience. SUMMARY OF THE INVENTION [0003] In view of this, embodiments of the present application provide a display panel and a display device to solve the problem of low brightness of display products with a privacy protection function in the prior art. [0004] A first aspect of the present application provides a display panel, comprising: a light-emitting element having a light-emitting surface; a...
