Embodiment 1

[0020] In this embodiment, a LCD seamless splicing display device has a structure such as figure 1 As shown, according to the direction of the light path, the LCD seamless splicing display device is sequentially arranged as an LCD panel 2 illuminated by a collimated beam, a diffuser mirror 3 and a screen 4, and the screen 4 faces the audience;

[0021] Wherein, the diffusion mirror 3 is placed behind the LCD panel 2 and is close to the LCD panel 2; the diffusion mirror 3 can adopt a negative Fresnel lens, a lens array, a holographic optical lens or other elements that can diffuse light beams; the screen 4 can be a diffused back The projection transmission screen is a diffusion film or a diffusion screen that scatters light beams, or an optical rear projection transmission screen with a fine structure; the collimated beam 1 is generated by an array of collimated light pipes, or by other components that can generate collimated beams produce.

[0022] The screen 4 can also be eq...

Embodiment 2

[0026] Another LCD seamless splicing display device of this embodiment, compared with Embodiment 1, differs in that according to the direction of the light path, the diffuser 3 is placed in front of the LCD panel 2 illuminated by the collimated light beam and close to the LCD panel 2 .

[0027] The working principle of the LCD seamless splicing display device of this embodiment is also based on the principle of thin beam linear propagation, specifically: the collimated beam 1 first passes through the diffuser 3 and then becomes a divergent beam, and then the beam passes through the LCD Panel 2 is divided into many small light beams by the pixels of LCD panel 2, and each pixel corresponds to small light beams of red, green, and blue colors. On the screen 4, the image area on the screen 4 can completely cover the LCD panel 2 and its edge area at this time, so the device also eliminates the splicing seam and its panel frame produced when the LCD panels are spliced.

Abstract

The invention provides a seamless splicing display device of an LCD. The device comprises an LCD panel with collimated beam illumination, a diffusion lens and a screen. According to the direction of a light path, the seamless splicing display device of the LCD is provided with the LCD panel with the collimated beam illumination, the diffusion lens and the screen sequentially, or provided with the diffusion lens with the collimated beam illumination, the LCD panel and the screen sequentially, wherein the collimated beam vertically enters the LCD panel or the diffusion lens by incidence. The display device is simple in structure and convenient for installation and can simply, conveniently and effectively eliminate the splicing seams generated when splicing LCD panels.

Description

technical field [0001] The invention relates to splicing display technology, in particular to an LCD seamless splicing display device. Background technique [0002] In recent years, with the rapid development of large-size LCD panels, LCD displays have gradually become the mainstream of display technology due to their advantages of ultra-thin, light weight, no radiation, and stable performance, and are gradually replacing CRT as the mainstream of displays. Although the super-sized LCD can be 80 inches or even 100 inches, it still cannot meet the requirements of users in occasions that require large-screen display (such as monitoring rooms, etc.). The field emerges. [0003] Due to the requirements of the surrounding driving circuit and production process, the LCD panel needs to reserve a certain space around the display image, and the image cannot be displayed to the edge area of ​​the panel. Generally, the width of this area exceeds 10mm, and it will increase with the incr...
