Abstract
The utility model relates to a reflector. By adopting a method of arranging light subduing parts such as a leak hole, a print screen dot and a black coating at the high-brightness area of the reflector, the reflecting capability of lights at the area is subdued, thus leading the area to conform with the periphery area on brightness, and then the brightness reflected to a whole liquid crystal module is lowered immediately, thus finally achieving the effect of improving the brightness uniformity of the liquid crystal module and solving the problem of insufficient brightness uniformity of the liquid crystal module. The method does not increase cost, but can be used flexibly so as to lead the reflector to achieve expected optical effect.

Traditional as shown in Figure 1 reflector plate adopts U type light source, and this type of is found when backlight in test, the brightness value aspect, and A district＞B district＞C district it seems it then is that the A district has a big clear zone from liquid crystal module, its overall brightness uniformity is relatively poor.
The utility model content
The technical problems to be solved in the utility model is that the relatively poor defective of module uniformity of luminance backlight at prior art provides a kind of reflector plate.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of reflector plate, comprise lamellar body, have the installing hole that is used to install tube stand on the described lamellar body, have at least one light that is used to reduce this zonal ray albedo on the described lamellar body and weaken parts.
In reflector plate described in the utility model, it is small opening that described light weakens parts.
In reflector plate described in the utility model, it is printing net-point that described light weakens parts.
In reflector plate described in the utility model, it is the black coating that described light weakens parts.
In reflector plate described in the utility model, described small opening is a kind of or its at least two kinds the combination in circular, square, rhombus, the ellipse.
In reflector plate described in the utility model, described printing net-point is a kind of or its at least two kinds the combination in circular, square, rhombus, the ellipse.
In reflector plate described in the utility model, described black coating is a kind of or its at least two kinds the combination in circular, square, rhombus, the ellipse.
Implement reflector plate of the present utility model, has following beneficial effect: adopt high-brightness region at reflector plate that light is set and weaken parts, as the method for small opening, printing net-point and black coating is set, weaken this zonal ray albedo, make this regional luminance and neighboring area be consistent, the brightness that is reflected to whole liquid crystal module reduces immediately, finally reaches the effect that improves the liquid crystal module brightness uniformity, has solved the not enough problem of liquid crystal module brightness uniformity.This method can not increase cost, and can apply in a flexible way, and makes it reach the optical effect of expectation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of common reflector plate;
Fig. 2 is the structural representation of the utility model reflector plate first embodiment;
Fig. 3 is the structural representation of the utility model reflector plate second embodiment;
Fig. 4 is the structural representation of the utility model reflector plate the 3rd embodiment.
The specific embodiment
Liquid crystal module is made up of module backlight and liquid crystal panel, liquid crystal panel itself does not have the characteristics of luminescence, module backlight is a kind of Optical devices, and module backlight mainly is made up of backboard, reflector plate, light source and exiting surface blooming piece, and reflector plate has played bigger decisive role to optical effect.Reflector plate and exiting surface blooming piece are arranged on the backboard, and light source is arranged on the reflector plate, and light source is between reflector plate and exiting surface blooming piece, and described reflector plate is used for the light that the light source on it produces is reflexed to the exiting surface blooming piece.
As shown in Figure 1, be common reflector plate, lamellar body 1 is provided with the installing hole 11 that is used to install Light support, and light source 2 is the U type.Common reflector plate is turned up by horizontal dotted line on the postnotum that is placed on or is affixed on module backlight, and the light that the light source on it 2 is produced reflexes on the exiting surface blooming piece.This type of reflector plate, the brightness value aspect, A district＞B district＞C district it seems it then is that the A district has a big clear zone from liquid crystal module, its overall brightness uniformity is bad.And product objective is, B district＞A district ≈ C district.Regional the time, need lower the brightness of a-quadrant apparently higher than other for the brightness of A district.The brightness the utility model that reduces A district among Fig. 1 discloses following technical scheme.
As shown in Figure 2, be the structural representation of the utility model reflector plate first embodiment.Reflector plate comprises lamellar body 1 in the present embodiment, has the installing hole 11 that is used to install tube stand on the described lamellar body 1.Light source 2 in the present embodiment is the U type, is provided with a plurality of light at high-brightness region A and weakens parts, and it is small opening 12 that this light weakens parts, is used to reduce this zonal ray albedo.Because being provided with small opening 12 these regional light albedoes weakens, the brightness that is reflected to liquid crystal module reduces immediately.Process can be adjusted to ≈ C district, brightness value A district to the debugging of the spacing of diameter, number and the small opening 12 of small opening 12, thereby realizes improving the liquid crystal module brightness uniformity.
As shown in Figure 3, be the structural representation of the utility model reflector plate second embodiment.In the present embodiment, reflector plate comprises lamellar body 1, has the installing hole 11 that is used to install tube stand on the described lamellar body 1, and light source 2 is the U type, is provided with a plurality of difform small openings 12 at high-brightness region A and is used to reduce this zonal ray albedo.Small opening 12 can be circular, square, rhombus, ellipse, but is not limited to above 4 kinds of shapes.Also can the small opening 12 of different shape be made up, realize required optical effect.Process can be adjusted to ≈ C district, brightness value A district to the debugging of the spacing of size, number and the small opening 12 of small opening 12, improves the liquid crystal module brightness uniformity.
