Abstract
The utility model provides a novel no-lamp-cover backlight module which comprises a frame, a reflecting plate, a light guide plate and light sources. The reflecting plate is arranged on the frame. Two sides of the reflecting plate are bent upward. The light guide plate is arranged on the reflecting plate. An optical rubber film is arranged above the reflecting plate. Two sides of the reflecting plate are respectively provided with one groove. Supporting elements and light sources are arranged in the grooves. The reflecting plate reflects light produced by light sources upward and the light guide plate conducts the light produced by light sources to the liquid crystal display panel. Two ends of the light sources are respectively provided with one inlaid element. Metal isolating electromagnetic interference is arranged on surfaces of the reflecting board, the inlaid element, or combination of the reflecting board and the inlaid element. With two sides of the reflecting plate being bent upward to cover the light sources, function of a lamp cover in an existing light tube module is substituted. Accordingly, the novel no-lamp-cover backlight module can effectively avoid possibility that the existing light tube provided with the light cover can interfere with the reflecting plate or the light guide plate because of the light cover, and simultaneously avoid shortcomings of light source leakage, dark areas produced and wrinkles and the like.
Description
Technical field
The utility model relates to a kind of backlight module device, especially relates to a kind of novel no lampshade module backlight.
Background technology
The used module backlight of available liquid crystal display generally includes LGP, tube module, establishes reflecting plate, blooming piece.And tube module generally includes reflector plate as lampshade, use the light that fluorescent tube is emitted and reflex in the LGP, and by this with the photoconduction of the fluorescent tube display panels to the front.
Yet in the existing module backlight, fluorescent tube places lampshade, in reality, often has light tube group and the loose contact between LGP because of lampshade to cause module backlight to form dark space, irradiation leakage or bad phenomenon such as generation fold and dark line in some areas.And lampshade is commonly metal material, and its hardness is hard than LGP, so when assembling or module heavy industry, be prone to the scratch LGP and produce dust.Moreover, in the existing module backlight used lampshade can with the easy mutual extrusion of reflecting plate, and make reflecting plate produce the phenomenon of fold because of extruding.
Summary of the invention
The utility model purpose provides a kind of novel no lampshade module backlight.Existing in prior technology module backlight forms the dark space in some areas, irradiation is leaked or technical problems such as generation fold and dark line to solve.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of novel no lampshade module backlight comprises framework, reflecting plate, LGP and light source; Said reflecting plate is arranged on the framework, and the both sides of this reflecting plate are upwards crooked; Said LGP is arranged on the reflecting plate, and the LGP top is provided with the optics glued membrane, and respectively there is a groove both sides of LGP, and support component is arranged in the groove, are provided with light source in this groove; Said reflecting plate reflects the light that this light source produced up, and LGP to panel of LCD, and respectively is provided with a chimeric element with photoconduction that light source produced on the two ends of light source; Said metal of isolating electromagnetic interference is located on the surface or its combination of the surface of reflecting plate, chimeric element.
The utility model utilizes two lateral bucklings of reflecting plate upwards to cover this light generation unit; Substitute the lampshade effect in the existing tube module; And utilize to coat the silica gel sheath of the metal that can isolate electromagnetic interference/or apply or be coated with the metal that to isolate electromagnetic interference in the opposed surface of this baffle reflection face; Effectively avoid the existing fluorescent tube that is provided with lampshade because this lampshade and can produce possibility of interference, avoid light source seepage, generation dark space and fold simultaneously and because of shortcomings such as the issuable electromagnetic interference of no lampshade with reflecting plate or LGP itself.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred implementation.
Fig. 2 is an A shown in Figure 1 place structure enlarged diagram.
The specific embodiment
Below through embodiment, and combine accompanying drawing, the technical scheme of the utility model is further specified.
Fig. 1 is the structural representation of the utility model preferred implementation; Fig. 2 is an A shown in Figure 1 place structure enlarged diagram.Combine Fig. 2 to know by Fig. 1, this novel no lampshade module backlight mainly is made up of framework 7, reflecting plate 3, LGP 5 and light source 4 etc.; Said reflecting plate 3 is arranged on the framework 7, and the both sides of this reflecting plate 3 are upwards crooked; Said LGP 5 is arranged on the reflecting plate 3; LGP 5 tops are provided with optics glued membrane 8; Respectively there is a groove 6 both sides of LGP 5, and in this groove 6, are provided with light source 4, said light source 4 two ends respectively be provided with a chimeric element 2 in order to this LGP groove 6 in set this support component 21 chimeric.And, be provided with a lead 1 in order to be electrically connected at this chimeric element 2 with other unit.Reflecting plate 3 is the predetermined lengths that extend in both sides more, utilize the length bending of this extension to coat this light source 4, thereby produce the function of light shield.
The set chimeric element in light source 4 two ends 2 surfaces are gone up or arbitrary surface-coated of these reflecting plate 3 reflectings surface, coat or stick the metal that can isolate electromagnetic interference, in order to eliminate issuable electromagnetic interference.In addition, in the module backlight that the liquid crystal indicator of the utility model is used, the quantity of this light source can be two or more.LGP 5 can in corresponding position forms groove 6, light source 4 be set, and the quantity of light source 4 is decided according to the purposes that institute designs or uses except that both sides.
Claims (1)
1. a novel no lampshade module backlight comprises framework, reflecting plate, LGP and light source; It is characterized in that said reflecting plate is arranged on the framework, the both sides of this reflecting plate are upwards crooked; Said LGP is arranged on the reflecting plate, and the LGP top is provided with the optics glued membrane, and respectively there is a groove both sides of LGP, and support component is arranged in the groove, are provided with light source in this groove; Said reflecting plate reflects the light that this light source produced up, and LGP to panel of LCD, and respectively is provided with a chimeric element with photoconduction that light source produced on the two ends of light source; Said metal of isolating electromagnetic interference is located on the surface or its combination of the surface of reflecting plate, chimeric element.
