The plurality of light source assembly 130 " light that sends is incident upon described side plate; the region incident intensity that wherein said side plate glazed thread is relatively concentrated is relatively strong thus defines first area 1211 ", and described first area 1211 on described side plate " beyond region be second area 1213 ".In the present embodiment, the plurality of light source assembly 130 " described optics cavity 124 it is arranged in two rows " in, as shown in Figure 2.In other embodiments, the plurality of light source assembly 130 " can also in multiple rows of arrangement or other geometries are distributed in described optics cavity 124 " in, specifically can set according to actual needs.Described 2 first side plates 121 " with often arrange described light source assembly 130 " two ends corresponding, described 2 second side plates 122 " with described light source assembly 130 " orientation parallel.Because of incident illumination intensity with the distance dependent of light source, therefore, in present embodiment, described first side plate 121 " on described first area 1211 " be positioned at rows of described light source assembly 130 " and two ends.
Further, in described first area 1211 " it is provided with ash stratum 1212 ", for reducing described first area 1211 " luminous reflectance; so that described first area 1211 " with described second area 1213 " luminous reflectance intensity suitable, so that arriving described optical module 140 from described side plate " brightness uniform.Wherein, described ash stratum 1212 " luminous reflectance less than described reflecting element 120 " luminous reflectance low, the grey stratum 1212 that is located on described side plate " form micro structure 1212 ".Described micro structure 1212 " described first side plate 121 can be respectively arranged on " described first area 1211 " and described second side plate 122 " described first area 1211 ", also can only be located at described 2 first side plates 121 " described first area 1211 " or described 2 second side plates 122 " described first area 1211 ".In present embodiment, described micro structure 1212 " be located at described 2 first side plates 121 " described first area 1211 ".Described ash stratum 1212 " by pasting or being formed at described first area 1211 by the way of coating " on.In present embodiment, described ash stratum 1212 " it is an adhesive tape.
Due to the described first area 1211 that light incident intensity is bigger " be provided with the described ash stratum 1212 that luminous reflectance is relatively low ", thus play the described first area 1211 reducing its place " the effect of luminous reflectance.Can be according to described light source assembly 130 " quantity and arrangement mode; regulate described ash stratum 1212 " position and size, thus regulate described first area 1211 " luminous reflectance; make this first area 1211 " luminous reflectance intensity and described second area 1213 " luminous reflectance intensity suitable, finally guarantee from described reflecting element 120 " reflect the light of uniform luminance and improve described display module 200 " display effect.In addition, by at described reflecting element 120 " described micro structure 1212 is set " regulate described reflecting element 120 " and the uniformity of emergent light; at backlight module 100 " slimming design in, by reducing the quantity of light source and the light source of big lighting angle can be selected, also do not result in the phenomenon of brightness disproportionation one, thus reach not only to meet slimming design but also do not affect the effect of display effect.
Above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention.
