Abstract

A diffusion plate (150), a backlight structure, and a display panel, the diffusion plate (150) being a flat plate-shaped structure, having a first surface and a second surface along the horizontal direction, a third surface and a fourth surface along the vertical direction, and a fifth surface and a sixth surface along a third direction, the third direction being perpendicular to the horizontal direction and the vertical direction; the first surface is a light ray incident face, and the second surface is positioned above the first surface and is a light ray emergent face; the second surface is connected to the third surface by means of a first connecting face and the second surface is connected to the fourth surface by means of a second connecting face, the first connecting face and the second connecting face being arcuate curved faces and / or smooth sloping faces. By means of providing a diffusion plate having arcuate curved faces and / or smooth sloping faces to replace a traditional flat plate diffusion plate, light rays can be projected by means of refraction to an area directly above a loading platform (130), visually reducing or even eliminating dark bands on the side edges of the display panel.

Description

technical field [0001] The invention relates to the field of trans-electronic display, in particular to a diffusion plate, a backlight structure and a display panel. Background technique [0002] With the development of display technology, the use of display panels is not limited to display screens of small devices such as televisions, monitors, and computer screens, but is also more widely used in large-size displays in the public domain. The demand for large-size, high-resolution displays used in airports, schools, large conference venues, exhibition halls, etc. is gradually increasing. However, at present, the maximum size of mass-produced mainstream displays is only about 65 inches, which cannot meet the needs of large-area display. Larger area display requirements need to be fulfilled by using splicing display. [0003] Splicing display requires that the display used for splicing has a very narrow frame design, and the seam between two adjacent displays is as small as...
