Embodiment Construction

[0021] The features and technical content of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments. The drawings are only used to explain the invention and not to limit it.

[0022] Such as figure 2 Shown is a schematic structural view of a prism sheet of the present invention. The prism sheet may comprise a layer of light-transmitting material, and the layer of light-transmitting material includes a first surface 1 whose shape is formed by wavy lines rotating around the center of the prism sheet with a fixed or variable radius first surface 1.

[0023] Preferably, in the above prism sheet, the center of the first surface 1 is a conical protrusion, figure 2 Take a cone as an example.

[0024] Preferably, in the above-mentioned prism sheet, the extension line B1 of the apex angle and the extension line B2 of the valley bottom of each mirror unit are concentric circles.

[0025] Specifically, the firs...

Abstract

The invention discloses a prism sheet. The prism sheet comprises a light transmission material layer; the light transmission material layer comprises a first surface; and the shape of the first surface is formed by rotation of a wavy line around the center of prism sheet in a fixed or variable radius. By adopting the technology disclosed by the invention, the front brightness of a display screen can be improved, and the diffraction phenomenon is avoided at the same time.

Description

technical field [0001] It relates to liquid crystal display technology, in particular to a prism sheet and a liquid crystal display screen. Background technique [0002] In liquid crystal display devices, in order to make more effective use of light energy, prism sheets with light-gathering effects are often used to gather light that deviates from the normal line of the screen at an excessive angle and increase the brightness of the front display. A common scheme of the prism sheet used in the prior art is shown in the attached drawing of the description figure 1 shown. Such as figure 1 As shown in the conventional prism sheet, when the extension line A of the apex angle is nearly parallel to the direction of the pixel array of the liquid crystal panel, it is easy to generate diffraction phenomenon and moiré, thereby affecting the display effect. [0003] How to solve the problem of moiré when the prism sheet is used in the prior art is exactly where the prior art needs t...
