Abstract
The utility model relates to the technical field of liquid crystal display devices, in particular to a high-brightness light guide plate, which comprises a plate body, a non-light tight plate, a reflecting layer, light sources and a hollow layer, wherein the non-light tight plate is arranged on the plate body; the reflecting layer is coated on the plate body; one side of the non-light tight plate is provided with the light sources; the hollow layer is arranged in the non-light tight plate; a light-tight component is coated on the reflecting layer; dimming parts are arranged in the hollow layer; and trapezoidal grooves are formed on the reflecting layer. The high-brightness light guide plate has a simple structure, and is favorable for application and popularization; the reflectivity of light rays is increased; luminous efficacy can be enhanced; the utilization rate of light is increased; the overall uniformity of brightness is improved; the number of the light sources is decreased; production cost is decreased; and developing quality is effectively improved.
Description
Technical field
The utility model relates to a kind of technical field of LCD device, especially a kind of plate for high luminance light guide.
Background technology
The brightness of existing LGP is difficult to reach the even effect of good whole property, is difficult to control the transmission direction of light beam, and is lower for the utilization rate of light, needs to increase the setting of light source, improved production cost, reduced the quality of video picture, shortened service life.
The utility model content
The deficiency that be difficult to evenly in order to overcome existing light guide plate luminance weak effect, brightness, production cost is high, the video picture quality is low and service life is short, the utility model provides a kind of plate for high luminance light guide.
The utility model solves the technical scheme that its technical problem adopted: a kind of plate for high luminance light guide; Comprise plate body, light-passing board, reflecting layer, light source and hollow layer, plate body is provided with light-passing board, is covered with one deck reflecting layer on the plate body; Light-passing board one side is provided with light source, is provided with hollow layer in the light-passing board.
According to another embodiment of the utility model, further comprise being coated with light tight assembly on the reflecting layer.
According to another embodiment of the utility model, further comprise being provided with the light modulation part in the hollow layer.
According to another embodiment of the utility model, comprise that further the reflecting layer is provided with dovetail groove.
The beneficial effect of the utility model is that this plate for high luminance light guide is simple in structure, has increased the reflectivity of light; Can strengthen light transmittance efficiency, improve the utilization rate of light, promote the even effect of bright globality; Reduced the setting of light source; Reduce production cost, effectively improved the quality of video picture, helped application.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. plate bodys among the figure, 2. light-passing board, 3. reflecting layer, 4. light source, 5. hollow layer, 6. light tight assembly, 7. light modulation part, 8. dovetail groove.
The specific embodiment
Like Fig. 1 is the structural representation of the utility model, and a kind of plate for high luminance light guide comprises plate body 1, light-passing board 2, reflecting layer 3, light source 4, hollow layer 5, light tight assembly 6, light modulation part 7 and dovetail groove 8; Plate body 1 is provided with light-passing board 2, is covered with one deck reflecting layer 3 on the plate body 1, and light-passing board 2 one sides are provided with light source 4; Be provided with hollow layer 5 in the light-passing board 2; Be coated with light tight assembly 6 on the reflecting layer 3, be provided with light modulation part 7 in the hollow layer 5, reflecting layer 3 is provided with dovetail groove 8.
During use, light-passing board 2 one sides are provided with light source 4, are provided with hollow layer 5 in the light-passing board 2; Be provided with light modulation part 7 in the hollow layer 5, can effectively distribute light and can evenly shed, the part of light modulation simultaneously 7 can be strengthened diffusion usefulness with the light guiding; Be covered with one deck reflecting layer 3 on the plate body 1, be coated with light tight assembly 6 on the reflecting layer 3, reflecting layer 3 is provided with dovetail groove 8; Can increase the brightness of LGP, make that the whole brightness of LGP is more even, so that comfortable visual display unit to be provided.This plate for high luminance light guide is simple in structure, has increased the reflectivity of light, can strengthen light transmittance efficiency; Improve the utilization rate of light, promoted the even effect of bright globality, reduced the setting of light source; Reduce production cost, effectively improved the quality of video picture, helped application.
