The diffuser plate may be a flat plate or a wedge plate, etc., as is well known to those skilled in the art.
Because the diffuser plate sets up the one side that deviates from reflector plate 20 at the LED light source, for preventing diffuser plate and LED light source contact, have between diffuser plate and the LED light source and dodge the clearance, have the clearance of mixing light promptly between diffuser plate and reflector plate 20, LED emits out partly direct injection diffuser plate of light, another part gets into the diffuser plate after reflector plate 20 reflects, two parts light mixes in mixing the light clearance.
It can be understood that the diffusion plate can be disposed on the side of the frame 12 away from the body 11, and the frame 12 can be disposed on the inner wall surface of the accommodating cavity, or a connection portion for connecting the diffusion plate can be disposed on the inner wall surface, such as a boss protruding from the inner wall surface, and the edge of the diffusion plate overlaps on the boss. The light exit distance can be considered to be the linear distance from the center of the LED light source to the location where the bezel 12 connects to the diffuser plate.
The optical film is disposed on a side of the diffuser plate away from the reflector 20, and is used for further refracting and scattering light emitted from the light emitting surface of the diffuser plate, so as to form a more uniform surface light source with higher brightness. The optical film may be one or more of a diffusion film, a prism film, and the like, or may be other optical films commonly used by those skilled in the art, such as a beam splitter, a polarizer, and the like, and details are not described herein.
Because be equipped with the LED light source between diffuser plate and the body 11, the diffuser plate has mixed light clearance with the 11 times of body, for avoiding the diffuser plate to one side protrusion of reflector plate 20, leads to diffuser plate and LED light source to collide and interfere, and backlight unit still includes: the supporting pieces protrude out of the body 11, and one end, away from the body 11, of each supporting piece abuts against the diffusion plate; the reflective sheet 20 is provided with a plurality of second avoidance holes 22 for avoiding the support member.
