Description of drawings
Fig. 1 is the cross-sectional view of down straight aphototropism mode set in the prior art.
Fig. 2 is the cross-sectional view of the utility model down straight aphototropism mode set.
The specific embodiment
The utility model provides a kind of down straight aphototropism mode set, liquid crystal module and liquid crystal display, and is clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below further describes with reference to the accompanying drawing the utility model of embodiment that develops simultaneously.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 2, Fig. 2 is the cross-sectional view of the utility model down straight aphototropism mode set.As shown in Figure 2, described down straight aphototropism mode set comprises light source 210, reflector plate 220 and diffuser plate 230, and described light source 210 is arranged on the reflector plate 220, and described diffuser plate 230 is positioned at light-emitting face one side of reflector plate 220, wherein, described reflector plate 220 arches upward and forms at least one curved reflecting surface 221.
Specifically, described light source 210 is used for emitting beam, and sufficient backlight illumination is provided, and in general a plurality of light sources are arranged in module backlight.Preferably, described light source 210 can be LED, i.e. led light source, and described light source 210 can also be CCFL.When practical application, described LED and lens combination are as light source.Described diffuser plate 230 is used for the light that diffused light source 210 sends, and described reflector plate 220 is used for the light that reflection source 210 sends, thereby improves the utilization rate of light source.Described diffuser plate 230 is positioned at reflecting surface one side of reflector plate 220.Wherein, described reflector plate 220 arches upward and forms at least one curved reflecting surface 221, and described curved reflecting surface 221 is used for the light that reflection source sends, and it is broken up homogenize.Because the structure of arc, make the curvature of reflector plate become big, in the largest light intensity angle of led light source when (being about 70 °), because reflector plate has mist degree, described curved reflecting surface 221 will light diffuse reflection to diffuser plate 230, light is broken up homogenize, make that the light on the diffuser plate 230 is more evenly gentle, thereby improved down straight aphototropism mode set lamp shadow (speck) phenomenon greatly.
