Abstract
The utility model provides a light guide plate mechanism for improving the panel brightness, which is used for regulating the light uniformity and improving the panel brightness. In the technical proposal, the light guide plate mechanism comprises a light guide plate, a reflection plate and a diffusion plate; wherein, the reflection plate and the diffusion plate are respectively arranged on the front side and the back side of the light guide plate; the front surface and the back surface of the light guide plate are both provided with light guide mesh points which are used for regulating the light uniformity. Compared with the prior art, because the upper surface and the lower surface of the light guide plate are provided with the light guide mesh points, and the density of the mesh points is one time thicker than the density of the mesh points distributed on one surface, the light beams can generate more diffused reflection and refraction in the light guide plate; the light beams after being regulated by the light guide plate with the mesh points on the two surfaces are more uniform; and the brightness of the light beams reflected from the diffusion plate is higher. The utility model can be used on the liquid crystal display, the small television and the module made by assembling the backlight and the TFT glass.
Description
Technical field
The utility model relates to a kind of back light that is used for, and particularly relates to the LGP of back light.
Background technology
The LGP of the backlight of present 19 cun widescreen liquid crystal is to adopt the design of single face leaded light site, cooperates scattered reflection with the light even light-guiding, makes the whole front panel uniformly light-emitting.
Single face is done the design of leaded light site relatively easily with simple, technical finesse and the also relative good adjustment of light design, and threshold is not too high, so the LGP of general 19 cun liquid crystal is all done the design of single face leaded light site.In order to consider light overall distribution uniformity, the distribution of site can not be accomplished too close, if be De Taimi, can cause the whole inequality of propagating of light because of the catadioptric undue concentration of light, makes final panel luminance and brightness uniformity be restricted.Satisfy high-end requirement in order to improve brightness, common way is to use other materials such as brightening piece to cooperate to improve panel luminance, but can increase cost like this.
The utility model content
Technical problem to be solved in the utility model is: a kind of LGP mechanism of improving panel luminance is provided, is used for adjusting the uniformity of light and the brightness that improves panel.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LGP mechanism of improving panel luminance, comprise LGP, be separately positioned on the reflector plate and the diffusion sheet of positive and negative two faces of LGP, on positive and negative two faces of described LGP, all be useful on and adjust the inhomogeneity leaded light of light site.
Preferably: described leaded light site can be circular, oval, square, bar shaped, disorderly count, the rule or the irregular leaded light site of arbitrary shape in the V-arrangement.
Preferably: also be provided with brightening piece on the exiting surface of described diffusion sheet.
Preferably: described LGP is the LGP of acryl material.
Preferably: described LGP is the LGP of transparent glass material.
The beneficial effects of the utility model are: compared to existing technology, the utility model is because the upper and lower surfaces of LGP all are formed with the leaded light site, the density that the density of its site is compared the site of single face design distribution is twice, diffuse reflection and refraction can more take place in the LGP the inside in light like this, more even through the adjusted light of the LGP of two-sided site, the brightness of the light that penetrates from diffusion sheet is higher.Be applied in the brightness that can obviously improve the LCD panel on the LCD, can be applied on LCD, the micro television and be assembled into application on the module at backlight and TFT glass.

The specific embodiment
The utility model provides a kind of LGP mechanism of improving panel luminance.
Existing light conducting plate structure as shown in Figure 1, useful etching method is made tiny intensive leaded light site 10 on the reverse side of LGP 1.
Embodiment of the present utility model is referring to Fig. 2, Fig. 3 and shown in Figure 4.Below the reverse side of LGP, be provided with reflector plate, above the front of LGP, be provided with scattering sheet.On upper and lower two faces of LGP, make tiny intensive leaded light site with the mould ejection formation or with additive methods such as etchings.
Referring to Fig. 2, the utility model is all to be useful on to adjust the inhomogeneity leaded light of light site, i.e. front leaded light site 12 and reverse side leaded light site 11 on positive and negative two faces of LGP 1.The leaded light site can be circular, oval, square, polygon, bar shaped, disorderly count, the rule or the irregular leaded light site of arbitrary shape in the V-arrangement.
The finished product structure backlight that contains the utility model light-guiding mechanism is referring to Fig. 4.The top of LGP 1 is followed successively by first diffusion sheet 20, second diffusion sheet 21, brightening piece 6, glue frame 13 and last chase 14 from the bottom to top.Below LGP 1, be followed successively by reflector plate 3 and following chase 15 from top to bottom.Be provided with the fluorescent tube 7 of band lampshade 8 and lampshade reflector plate 9 at the side of LGP 1.
Reflection of light and refraction principle that the utility model utilizes referring to Fig. 3, are provided with diffusion sheet 2 above leaded light site, front 12, be provided with reflector plate 3 above reverse side leaded light site 11.The light 5 that sends by the light source 4 of being located at LGP 1 side, when the end incident of light source 4 from LGP 1, light 5 is run into the leaded light site that differs in size, and omnidirectional reflection and refraction can take place, refracted ray is reflected back toward again in the LGP 1 when running into beneath reflector plate 3, and the site is big more, the catadioptric ability that light takes place is stronger, light continues the big and intensive direction propagation toward the site, other end, light is on LGP like this, refraction and reflection constantly take place in following two faces, light can reuse, the utilization rate of light improves greatly, the final total reflection condition that destroys, the diffusion sheet 2 that sees through LGP 1 top penetrates, and light penetrates from the front of LGP 1 and become very even via diffusion sheet 2, can realize higher brightness.
