Abstract: A liquid crystal display (LCD) is disclosed. The LCD comprises a front frame, a panel, a plastic frame and an optical film assembly. The panel comprises a display region and a non-display region, and the plastic frame and the front frame cooperate with each other to sandwich the non-display region of the panel therebetween. The plastic frame is formed with a V-groove(s) on a surface thereof that faces towards a light exiting surface of the optical film assembly. In this way, light rays traveling through the optical film assembly to the lower surface of the plastic frame are reflected by the V-groove(s) so as to be mostly concentrated onto the non-display region of the panel and then gradually attenuated to disappear. This can reduce the bright lines appearing in the display region of the panel and, consequently, improve the displaying effect of the whole LCD.

Abstract: The invention relates to an LGP and a back light module thereof, wherein the LGP comprises a light input surface, a bottom surface and a light output surface opposite to the bottom surface, and is characterized in that the bottom surface and/or the light output surface is provided with a plurality of microstructures, distribution rules for microstructures along the direction parallel to the light input surface of the LGP are: the microstructures in the middle of the LGP are closely arranged, and the microstructures on the two sides are sparsely arranged. In the LGP provided in the invention, the light output in the direction parallel to the light input surface can reach the brightness distribution with high middle and low edges, thereby achieving higher efficiency of light energy utilization.

Abstract: The present disclosure provides a backlight module. The backlight module includes a light guide plate and a light bar. The light guide plate includes a light incident surface, and the light bar is adjacent to the light incident surface. The light bar includes a printed circuit board and a plurality of point light sources alternately located on the printed circuit board. Each point light source includes an illuminator and an encapsulation apparatus. The encapsulation apparatus encapsulates the illuminator and fixes the light guide plate for limiting a distance between the light incident surface and the illuminator. The present disclosure also provides a liquid crystal display employing the backlight module.

Abstract: A backlight unit has a frame, at least one optical film, and at least one light source accommodated in the frame. The frame has a top wall, a bottom wall opposite to the top wall, two opposite side walls, and at least one protuberance integrated on the top wall. The at least one optical film includes at least one through-hole with respect to the at least one protuberance. The at least one protuberance drills through the at least one through-hole for hanging the at least one optical film on the frame.
