Problems solved by technology

[0003] But no matter what kind of display screen is made, it is inevitable to use a multi-material film layer structure, and the refractive index of different film layers will be different, so the external ambient light will occur between the layers when it is incident on the display screen. Reflection and refraction, due to the difference in refractive index, reflection accumulation occurs between layers, resulting in high reflectivity of ambient light on the surface of the display panel. When the display is displayed, this part of the reflected light will reduce the contrast of the display screen, thereby reducing the viewing experience

Abstract

The invention discloses a display panel and a display device. The display panel includes a display substrate, a first polarization layer positioned on a light going-out side of the display substrate, and at least one functional film layer positioned between the first polarization layer and the display substrate; at least one interface of each film layer is an uneven interface having a plurality of bar-shaped concave-convex edges which are arranged in parallel; the direction of the bar-shaped concave-convex edges of the outmost uneven interface is perpendicular to the polarization direction of the first polarization layer, the bar-shaped concave-convex edges have slopes extending in the direction of edges, and an included angle between the slopes and a flat surface is a Brewster angle that light enters the uneven interface. When environment light perpendicularly enters the display panel, the environment light can enter the display panel at the Brewster angle, the environment light passing through the first polarization layer is converted into linear polarized light, reflective light on the interface, of the perpendicularly incident environment light can be eliminated according to the Brewster law, and the surface reflectivity of the display panel is decreased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the continuous development of display technology, various types of display devices emerge in an endless stream. Currently, mainstream display screens mainly include liquid crystal display screens and organic light emitting diode display screens. Liquid Crystal Display (LCD for short) is cheaper to manufacture than organic light-emitting diode displays, but the LCD display cannot emit light by itself, and a backlight module needs to be installed. Organic Light-Emitting Diode (OLED for short) uses self-luminous materials, does not require a backlight module, and has a wide viewing angle and fast response speed. [0003] But no matter what kind of display screen is made, it is inevitable to use a multi-material film layer structure, and the refractive index of different film layers will be different, so the e...
