Description

The present invention relates to a backlight structure of a liquid crystal face plate, and provides a uniform luminance particularly for display on a large monitor.

FIG. 1 shows a backlight structure of a general liquid crystal face plate. The backlight structure 1 is configured by combining a plurality of monitor modules 10 having different sizes. Each monitor module 10 includes a light source 11, a diffusion plate 12, an optical film piece 13, and a liquid crystal face plate 14, and each monitor module 10 is combined with a large monitor. If you look at this monitor, you can clearly see the gap lines between each monitor module 10, and you can see that the screen is divided, which reduces the image effect of large monitors.

The problem to be solved is that the luminance is insufficient and the known large liquid crystal face plate is a combination of a plurality of liquid crystal face plates, so that when displayed, the image appears to be divided by the gap between the face plates.

The present invention comprises an assembly type backlight source and a large liquid crystal face plate. This assembly type backlight source is configured by installing a plurality of light sources in a light box. Furthermore, a diffusion plate, an optical film piece, and a large liquid crystal face plate are installed on the top of the light box and covered. Among them, the light source of the backlight module has the main feature that a plurality of light source units are installed by an assembly method.

The backlight structure of the liquid crystal faceplate of the present invention has advantages that it is easy to assemble, effectively improves the luminance deficiency, and is displayed without being divided by a single large liquid crystal screen.

Embodiments of the present invention will be described below with reference to the drawings.

The present invention is a basic structure of the backlight module 1 and is composed of an assembly-type backlight source 15 and a large liquid crystal face plate 16. The assembly type backlight source 15 is configured by installing a plurality of light source units 30 in a light box 17. Furthermore, a diffusion plate 12, an optical film piece 13, and a large liquid crystal face plate 16 are installed on the uppermost lid of the light box 17. As shown in FIG. 2, the light source unit 30 architecture includes a plurality of light tubes 40 installed on both sides of the light cover 31 inside the light source unit 30. The display effect is good and the screen is not divided when looking at the monitor.

At the time of implementation, the architecture of the light source unit 30 is as shown in FIG. 3, and a support base 311 protruding at the inner part of the light cover 31 is installed, and the ends of the light tube 40 are fixed to both side walls of the support base 311. A silicon rubber cover 312 is installed. The light tubes 40 on both sides inside the light cover 31 are installed by a method in which the tube ends are fixed to the side walls of the support base 311 and the fixed ends serve as the positions where the light tube 40 electrode 41 is installed. Each light tube 40 electrode circuit of the backlight module is concentrated at the middle position of the light cover 31, making it easy to assemble the light tube. Further, the light source of each light tube is strengthened by the reflection action of the support 311.

The light tubes 40 on both sides inside the light cover 31 may be installed in a mutually compatible manner as shown in FIG. 3, or in a cross-interlaced manner as shown in FIG. As shown in FIG. 3, a plurality of convex pieces 313 are installed at the uppermost end 311 of the support base 311. Each convex piece 313 supports the diffusion plate 12 and the optical film piece 13, and the diffusion plate 12 and the optical film piece 13 do not sink.

In addition, each light source unit 30 is configured by installing each light tube 40 in the container 32 as shown in FIGS. 5A and 5B and FIGS. 6A and 6B (see FIG. 6A). The light source unit 30 is also configured by installing a plurality of light emitting diodes 40 ′ on the container 32 (see FIG. 6B). Further, a backlight source is combined with the container 32, and the form of the container 32 is as shown in FIGS. 5A and 5B. Further, the container 32 is made of a light transmitting material, and the related diffuser plate 12 and the optical film piece 13 are attached to the light transmitting layer 321 and integrated, and a plurality of light adjusting units 50 are installed on the light transmitting layer 321. To do. Further, as shown in FIG. 7, the light adjusting unit 50 has a light-transmitting layer 321 whose surface has an arc-shaped concave tank (may be V-shaped or U-shaped), or an arc-shaped convex strip (V-shaped or U-shaped). (Good), composed of uneven points of laser, compression, cutting, spray smithing, printing, etching or network system, and the light rays of the light tube 40 are uniformly monitored by the prism and reflection action of the light rays that have passed.
