Abstract
The utility model discloses a backlight module for three-dimensional liquid crystal displays, which comprises an upper diffusion chip, a bottom diffusion chip and a grating chip arranged on the outboard of the upper diffusion chip. The thickness of the whole display module is reduced because the grating component is integrated into the backlight module instead of employing the independent liquid crystal gratings, and the material cost of producing the whole liquid crystal displays is reduced because of the employment of the lightproof coatings, the coated glass flakes or the coated plastic flake as the grating chips. Furthermore, the production technology is simple and mature and good three-dimensional display effects can be achieved.
Description
Technical field
The present invention relates to a kind of back light module unit structure, particularly a kind of back light module unit structure of the stereo-liquid crystal display device based on the luminous grid technology of parallax.
Background technology
Along with fast development of computer technology, increasing application all can relate to solid and play up with picture and show, stereoscopic image display fully reproduces out with the three-dimensional information of scene, show image with depth feelings, the observer can directly find out the distance of each object in the image, see clearly the real distribution situation of image rapidly intuitively, thereby make the beholder can obtain more comprehensive and real information.
Existing stereo display technique has a variety of, wherein, the luminous grid technology of parallax is the directive with light grid-control system backlight light, make the light left and right sides pixel of directive LCD respectively, by existing display and backlight between be equipped with a grating and realize 3-D display, grating is used for cutting apart the travel path of light, makes the light left and right sides pixel of directive LCD respectively, makes right and left eyes see the image of different angles respectively.Two kinds of stereoscopic overlap images are incorporated into and have just produced 3-D effect together.The luminous grid technology of parallax becomes the hot technology of present stereo display because the beholder need not wear special spectacles and watch.Since this technology tradition mode be LCD with backlight between add the liquid crystal grating assembly, make it to produce luminous grid effect, but add the thickness that the liquid crystal grating assembly can increase whole demonstration module, and can increase cost.
Summary of the invention
The utility model proposes a kind of module backlight that is used for stereo-liquid crystal display device, can reduce the integral thickness of LCD, and obtain preferable stereo display effect.
Module backlight of the present utility model comprises diffusion sheet, following diffusion sheet, lenticular lenses, and lenticular lenses is positioned at the outside of expansion sheet.
Preferably, module backlight also comprises: go up brightening piece, brightening piece, light guide plate, light source, light source reflecting housing, light modulation site, reflector plate, module frame down, the top-down order of placement of each device is: lenticular lenses, go up diffusion sheet, go up brightening piece, brightening piece, diffusion sheet, light guide plate, light source, light source reflecting housing, light modulation site, reflector plate, module frame down down.
Preferably, described lenticular lenses is shading patch, coating glass sheet or coating plastic sheet.Its lenticular lenses coating is black matrix coating.
The beneficial effects of the utility model are: owing to do not adopt independently liquid crystal grating, but in module backlight, lenticular lenses is set, can reduce the whole thickness that shows module, owing to adopt shading patch, coating glass sheet or coating plastic sheet as lenticular lenses, reduced the integral material cost of LCD, production technology is also ripe simple, and can obtain good stereo display effect.

Embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings the utility model is described in further detail.
The principle of the luminous grid stereo display technique of parallax as shown in Figure 1, the light that backlight 7 sends blocks through grating 5, make part light 6 see through grating 5 directive LCD 3, the light 6 that sees through is through after the modulation of LCD 3, directive human eye 1, human eye 2, two eyes of people are seen different pixel 4 respectively.Therefore, as long as make the adjacent row pixel of liquid crystal panel 4 show the image of different angles respectively,, make the people produce three-dimensional sensation owing to the synthesis of human eye right and left eyes.
Grating planar as shown in Figure 2, the grating place of blocking 8 is used for the light that occluded pixels is sent, and grating printing opacity place 9 sees through light, and they have formed lenticular lenses 10.
The structure of existing common module backlight as shown in Figure 3 is respectively diffusion sheet 11, last brightening piece 12, following brightening piece 13, following diffusion sheet 14, light guide plate 15, light source 16, light source reflecting housing 17, light modulation site 18, reflector plate 19, module frame 20 from top to bottom.
Available liquid crystal grating as shown in Figure 4 shows the structure of module, is respectively LCD 3 from top to bottom, liquid crystal grating 22 and module backlight 7.
Be illustrated in figure 5 as back light module unit structure of the present invention, the structure of module backlight is the lenticular lenses 21 of arranging from top to bottom, go up diffusion sheet 11, go up brightening piece 12, brightening piece 13, diffusion sheet 14, light guide plate 15, light source 16, light source reflecting housing 17, light modulation site 18, reflector plate 19, module frame 20 down down.Lenticular lenses 21 can be used shading patch, coating glass sheet or coating plastic sheet.Glass sheet coating or plastic sheet coating are specifically as follows black matrix (BM, Black Matrix) coating.
