背光模组及液晶显示装置
摘要：
本发明公开一种背光模组包括导光板、光源组件及边框，所述边框包围所述导光板，所述光源组件设于所述导光板的入光面与所述边框之间，所述光源组件包括基板、发光体和透明体，所述透明体将所述发光体封装在所述基板上，其特征在于，所述透明体之与所述发光体正对的外表面为出光面，所述出光面设有凹槽，所述凹槽正对所述导光板的入光面，所述凹槽使得所述发光体射出的光线向所述导光板中心的方向聚集，能够提高所述背光模组的耦光效率。本发明还提供一种液晶显示装置。
摘要（英）：

The disclosure is related to a backlight module comprising a light guide plate, a light source assembly and a frame. The frame surrounds the light guide plate. The light source assembly is arranged between the light incident surface of the light guide plate and the frame. The light source assembly comprises a substrate, a light emitting body and a transparent body. The transparent body packages the light emitting body on the substrate. The outer surface of the transparent body facing the light emitting body is a light emitting surface having a groove formed thereon facing the light incident surface of the light guide plate. The groove enables the light emitted from the transparent body to congest toward the direction of the center of the light guide plate to increase the optical coupling efficient of the backlight module. The disclosure further provides a liquid crystal display device.
