Abstract
The utility model discloses a lighting system for an LCD (liquid crystal display) projector, which relates to the field of projectors. The lighting system comprises a control circuit (1), an LCD board (2), an anti-reflection layer (3), a projection lens (4), a projection screen (5) and a light source (6), wherein the control circuit (1) is connected with the LCD board (2) through a control signal, the two sides of the LCD board (2) are respectively provided with the anti-reflection layer (3) and the projection lens (4), one side of the anti-reflection layer (3) is provided with the light source (6), and one side of the projection lens (4) is provided with the projection screen (5). According to the utility model, the anti-reflection layer is added between a liquid crystal panel and the light source to improve the utilization ratio of the light source, and the service life of the light source is prolonged; and the lighting system is low in cost and convenient to use.
Description
Technical field
The utility model relates to field of projector, be specifically related to a kind of LCD illuminating system of projector.
Background technology
Present projector adopts three LCD plates of red, green, blue mostly, after red, green, blue three coloured light shine respectively on the corresponding LCD plate, be subjected to respectively the control output image information of LCD plate, make the three beams convergence of rays by color-combination prism again, obtain image by the projection lens projection.Three-chip type projector is owing to brightness is high, resolution is high, rich color is widely used, but its shortcomings such as expensive and mechanical registeration difficulty have also limited it and have entered family market, existing market also has the LCD projector of monolithic design, this projector volume is little, lightweight, easy to operate, simultaneously do not need to close the coloured light road, only need to use a slice LCD plate and a slice control chip, this greatly reduces cost, and making projector enter family becomes possibility.But the shortcomings such as light source life is short, resolution is lower become the obstacle that single panel projector is promoted.
The utility model content
For the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of LCD illuminating system of projector, and its light utilization is high, can postpone light source life, and cost is low, and is easy to use.
To achieve these goals, the utility model is to realize by the following technical solutions: the LCD illuminating system of projector, it comprises control circuit, LCD plate, antireflection layer, projection lens, projection screen and light source, control circuit links to each other with the LCD plate by control signal, LCD plate both sides are respectively arranged with antireflection layer, projection lens, antireflection layer one side is provided with light source, and the first side of projection lens is provided with projection screen.
According to above-mentioned LCD illuminating system of projector, wherein, described antireflection layer opposite side is provided with cover glass and color filter.
According to above-mentioned LCD illuminating system of projector, wherein, described antireflection layer adopts hard transparent material.
The utility model adds antireflection layer between liquid crystal panel and light source method improves the light source utilization factor, postpones light source life, and cost is low, and is easy to use.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of antireflection layer in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1-2, this embodiment is by the following technical solutions: comprise control circuit 1, LCD plate 2, antireflection layer 3, projection lens 4, projection screen 5 and light source 6, control circuit 1 links to each other with LCD plate 2 by control signal, LCD plate 2 both sides are respectively arranged with antireflection layer 3, projection lens 4, antireflection layer 3 one sides are provided with light source 6, and projection lens 4 one sides are provided with projection screen 5.
It should be noted that described antireflection layer 3 opposite sides are provided with cover glass 31 and color filter 32.
This embodiment adopts the parallel beam irradiation to show the LCD plate 2 of image, projects on the projection screen 5 by the picture of projection lens 4 with LCD again, adds antireflection layer 3 in light source 6 one sides, and it disposes matrix of microlenses one to one to each pixel.Antireflection layer adopts hard transparent material, and its phototropic face lenslet diameter is the width of a pixel, and the another side that each lenticule is corresponding (namely to the LCD face) has three less lenticules, and they are three look color filters of corresponding each pixel one by one.
This embodiment adds antireflection layer between liquid crystal panel and light source method improves the light source utilization factor, postpones light source life, and cost is low, and is easy to use.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
