Abstract
The utility model relates to a backlight source, which comprises a bottom plate and a light guide plate arranged on the bottom plate, wherein, a panel placement surface for placing a panel is provided on the upper surface of the light guide plate by injection molding. Furthermore, a plurality of bumps serving as the light emergent surface provided on the upper surface of the light guide plate by injection molding. The backlight source of the utility model can obviate the need of upper plastic frame of the prior art by providing the panel placement surface on the light guide plate by injection molding, thereby simplifying the component, improving the assembly performance and reducing the cost of the backlight source.
Description
Technical field
The utility model relates to a kind of LCD, relates in particular to a kind of Backlight For Liquid Crystal Display Panels.
Background technology
Traditional backlight is made up of base plate, LGP (LGP), last plastic frame, light source etc., last plastic frame is except the integration fixation with backlight integral body, panel of LCD (panel) need be placed on the panel placed side of plastic frame, then with metal edge frame, cover plates etc. fit together, and form complete Liquid Crystal Module.
Because at present traditional backlight number of components is more, frame for movement is comparatively complicated, so the assembling of backlight and repair operation and all seem comparatively loaded down with trivial details; Because parts are more, be difficult to reduce cost simultaneously.Therefore, reduce owing to the various inconvenience that brings of parts, the assembling performance is bad, and the cost of reduction backlight etc. all is a urgent problem.
The utility model content
The purpose of this utility model is to provide a kind of backlight by some embodiment, effectively solves existing backlight owing to the various inconvenience that brings of parts, to reduce the production cost of backlight.
Previous embodiment of the present utility model specifically comprises base plate and the LGP that is arranged on the described base plate, and the upper surface of described LGP is formed with the panel placed side of placing panel with injection molding.
In addition, the upper surface of LGP is formed with a plurality of projectioies as exiting surface with injection molding; The bottom of LGP is formed with the light source placed side of placing light source with injection molding; Be pasted with reflectance coating or shading rubber belt around the described panel placed side; Be coated with black leakproof photosphere around the described panel placed side; Backlight also comprises metal edge frame, and described metal edge frame and base plate are fixed by card and mode; Described base plate and base plate both sides inwall are pasted with reflectance coating or shading rubber belt.
The utility model backlight is by directly injecting the panel placed side that LCD is installed on LGP, saved last plastic frame, solve existing backlight because the various defective of bringing of parts has improved the assembling performance, also reduced the cost of backlight simultaneously.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model backlight;
Fig. 2 is the vertical view of structure shown in Figure 1.
Description of reference numerals:
The 1-base plate; The 2-LGP; The 3-panel;
The 4-metal edge frame; The 5-light source; The 6-exiting surface;
Reflectance coating at the bottom of the 7-; 8-panel placed side; 9-light source placed side.
The specific embodiment
Fig. 1 is the structural representation of the utility model backlight one embodiment, as shown in Figure 1, backlight comprises base plate 1 and the LGP 2 that is arranged on the base plate 1, the upper surface of LGP is formed with the panel placed side 8 of placing panel with injection molding, simultaneously, the upper surface of LGP 2 is formed with a plurality of projectioies as exiting surface 6 with injection molding, and the bottom of LGP 2 is formed with the light source placed side 9 of placing light source 5 with injection molding.This backlight also comprises metal edge frame 4, and metal edge frame 4 and base plate 1 are by card and mode is direct and LGP interfixes, and form complete integral body.
Wherein, the placed side of panel of LCD being directly injection-moulded on the LGP, is size and dimension as required, by an extrusion modling of mould, change traditional passing through unnecessary portions has been removed in the cutting of sheet material, provided cost savings, reduced waste material; In addition, the formation of exiting surface is in injection moulding process, exiting surface position at mould is provided with compact arranged sphere or hemispherical groove, the size of groove can change according to different demands with distribution, when injection moulding, groove on the corresponding mould promptly can directly form spot-like projections on the exiting surface of LGP 2, and light is played scattering process.
Above-mentioned backlight has saved last plastic frame by directly inject the panel placed side that LCD is installed on LGP, and it is simple that structure becomes, therefore, reduced because the various inconvenience that brings of parts has improved the assembling performance, also reduced the cost of backlight simultaneously.
In addition,, on base plate 1,, expose from side, attach reflectance coating or shading rubber belt at the both sides of base plate inwall in order to prevent light with end reflectance coating 7 in order to improve the utilization rate of light.Simultaneously,, around panel placed side 8, be pasted with reflectance coating or shading rubber belt, perhaps directly on the panel placed side, be coated with black leakproof photosphere for fear of light leak.By above-mentioned setting, improved the utilization rate of light effectively.
Fig. 2 is the vertical view of structure shown in Figure 1, the position of panel 3 and LGP 2 as shown in Figure 2, for fear of light leak, around the panel placed side 8 of LGP, attach reflectance coating or shading rubber belt, make from around the light that spills by the reflection recycling, not only can avoid light leak, also can improve the service efficiency of light, improve brightness.In addition, also can be around the panel placed side 8 of LGP painting black leakproof photosphere, the light loss of avoiding overflowing of light to cause has improved the service efficiency of light.By above-mentioned setting, improved the service efficiency and the brightness of light preferably.
It should be noted that at last: above each embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
