The utility model embodiment discloses a kind of reflective backlight frame, including：Framework is cylinder type, and a mounting groove is offered on the inner wall of its opening；Liquid crystal display panel is set in mounting groove, surrounds to form a cavity with framework；Reflecting plate is built in cavity, reflecting plate be it is arc-shaped, arc surface towards liquid crystal display panel arrange；Light source is built in cavity, and is coaxially disposed with framework, and light source includes light bulb and connecting rod, and connecting rod lower end connects framework inner wall, upper end connection bulb lower end.Compared with prior art, the utility model has the advantages that：The reflective backlight frame of the utility model uses an arc reflection plate, and light source is located on the axis of arc reflection plate, by the diffusing reflection screen illuminating of reflecting plate, eliminates the luminance difference in the middle part of screen with edge.
Description
Technical field
The utility model relates to technical field of liquid crystal display more particularly to a kind of reflective backlight frames.
Background technique
Liquid crystal display device (LCD, Liquid Crystal Display) has thin fuselage, power saving, radiationless etc. numerous
Advantage is widely used.There are two types of the backlight modes made now of LED：Side entering type and straight-down negative.Side entering type be by
LED is placed on the side of light guide plate, after lighting LED, by light guide plate by light equably behind liquid crystal display panel it is shinny, can then see
To the image shown in liquid crystal display panel front；The difference of straight-down negative and side entering type is：LED is evenly placed upon liquid crystal surface by it
Behind plate, after lighting LED, so that it may in the display image that liquid crystal display panel front is seen.
Direct-type backlight refers to that a fairly large number of LED light array is placed on the straight lower section of liquid crystal display panel, LED light light-emitting surface with
Liquid crystal display panel is parallel, due to needing the lamp grain of biggish deep space and the more number of use from LED light to liquid crystal display panel, because
This, heavier-weight all larger using the LCD MODULE thickness and power consumption of direct-type backlight；Side entrance back is index
It measures less LED light and is placed on liquid crystal display panel side-lower, LED light light-emitting surface and liquid crystal display panel are in 90 °, make liquid crystal by light guide plate
Brightness uniformity under panel, although the LCD MODULE thickness and power consumption using side entrance back are smaller, lighter in weight,
It is the problems such as light guide plate shakes and deforms frequent occurrence.
Application No. is 201220052170.0 utility model patents to be arranged in the two sides below screen for light source, using anti-
The diffusing reflection of plate is penetrated to realize shining for screen.Reflecting plate is obliquely installed in the design scheme, is shielded closer to screen center's distance
Curtain is closer, there is reflected light deficiency, causing screen center with edge, there are luminance differences, impact to imaging.
Utility model content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, propose a kind of reflective backlight frame, solve existing skill
There are luminance differences with edge for Shu Zhong screen center, the technical issues of impacting to imaging.
In order to reach above-mentioned technical purpose, the utility model embodiment provides a kind of reflective backlight frame, this is reflective
Backlight frame includes：
Framework is cylinder type, and a mounting groove is offered on the inner wall of its opening；
Liquid crystal display panel is set in mounting groove, surrounds to form a cavity with framework；
Reflecting plate is built in cavity, reflecting plate be it is arc-shaped, arc surface towards liquid crystal display panel arrange；
Light source is built in cavity, and is coaxially disposed with framework, and light source includes light bulb and connecting rod, under connecting rod
End connection framework inner wall, upper end connection bulb lower end.
Compared with prior art, the utility model has the advantages that：The reflective backlight frame of the utility model is adopted
With an arc reflection plate, light source is located on the axis of arc reflection plate, by the diffusing reflection screen illuminating of reflecting plate, eliminates screen
The luminance difference at middle part and edge.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of reflective backlight frame provided by the utility model；
Fig. 2 is the top view of reflective backlight frame provided by the utility model；
Fig. 3 is the enlarged drawing of light source in Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
It is the structural schematic diagram of reflective backlight frame provided by the utility model to Fig. 3, Fig. 1 referring to Figure 1；Fig. 2 is this
The top view for the reflective backlight frame that utility model provides；Fig. 3 is the enlarged drawing of light source in Fig. 1.
Reflective backlight frame includes：Framework 1, liquid crystal display panel 2, reflecting plate 3 and light source 4.
Framework 1 is cylinder type, and a mounting groove is offered on the inner wall of its opening.Liquid crystal display panel 2 is set to mounting groove
It is interior, it surrounds to form a cavity with framework 1.Reflecting plate 3 is built in cavity, reflecting plate be it is arc-shaped, arc surface is towards liquid crystal surface
Plate 2 is arranged.Light source 4 is built in cavity, and is coaxially disposed with framework 1, and light source 4 includes connecting rod 41, light bulb 42 and light-blocking
Plate 43.41 lower end of connecting rod connects 1 inner wall of framework, 42 lower end of upper end connection bulb.Light bulb 42 is LED bulb, and reflecting plate 3
Tip height is greater than the tip height of light bulb 42.Light-blocking lid 43 is set between light bulb 42 and liquid crystal display panel 2, light-blocking lid 43 it is big
Small and position setting, makes it just block light bulb 42, avoids 42 direct projection liquid crystal display panel of light bulb, while guaranteeing that it is irradiated to reflection
Light on plate 3 is more as far as possible, avoids the unnecessary loss of light.
Implement the utility model embodiment, has the advantages that：The reflective backlight frame of the utility model uses one
Arc reflection plate, light source are located on the axis of arc reflection plate, by the diffusing reflection screen illuminating of reflecting plate, eliminate in the middle part of screen
With the luminance difference at edge.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
