Embodiment Construction

[0025] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0026] Firstly, the prior art will be described with reference to the accompanying drawings. see figure 1 , the display panel in the prior art generally includes an "L"-shaped backplane 110, a PCB board 120 located above a portion of the backplane 110 extending in the horizontal direction, a zigzag bearing platform 130, and a backlight located above the PCB board. A ...

Abstract

The invention provides a diffusion plate, a backlight structure and a display panel. The diffusion plate takes the shape of a flat plate, and is provided with a first surface and a second surface along a horizontal direction; a third surface and a fourth surface along a vertical direction; a fifth surface and a sixth surface along a third direction; the third direction is perpendicular to the horizontal direction and the vertical direction; the first surface is the incident surface of light rays; the second surface is positioned above the first surface, and is the ejection surface of light rays; the second surface is connected with the third surface via a first connection surface; the second surface is connected with the fourth surface via a second connection surface; the first connectionsurface and the second connection surface are arc-shaped curved surface and / or smooth slopes. The invention provides the diffusion plate with the arc-shaped curved surfaces and / or the smooth slopes toreplace the traditional flat-plate diffusion plate, so that the light rays can be projected to an area right above a bearing platform, and thus dark bands on the edges of the display panel are visually reduced even eliminated.

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...
