Embodiment Construction

[0021] Such as figure 1 As shown, a side-entry reflective sheet includes a mixing part 1 and a mounting part 2. The mixing part 1 and the mounting part 2 are separated by a suture 3. The mixing part 1 is provided with a light-transmitting opening 101, and the light-transmitting opening 101 is rhombus-shaped. , the light-transmitting openings 101 close to the suture 3 correspond to the spacing positions of the LED light sources, and the light-transmitting openings 101 are arranged horizontally. Both sides of the mixing part 1 are provided with hanging ears 102 , and above the hanging ears 102 are provided with detachably connected mylar sheets 103 . The mounting part 2 is provided with a fixing opening 201 and a fool-proof chamfer 202 for production assembly. Such as figure 2 As shown, the backlight module includes a side-type reflector 4 , a back plate 5 , a heat sink 6 , a light guide plate 7 , an optical film 8 , a plastic frame 9 , a light strip, a PCB board 10 and LED l...

Abstract

The invention relates to the field of liquid crystal display, in particular to a lateral entrance type reflector plate and a backlight module containing the same. The lateral entrance type reflector plate comprises a mixing portion and an installation portion. The mixing portion and the insulation portion are divided by roulettes. Transmitting openings are formed in the mixing portion, the transmitting openings close to the roulettes are corresponding to an LED light source interval positions. The reflector plate of the mixing portion is attached to an upper surface of a light guide panel by folding the roulettes. Most of light ray of heat pot regions close to the LED light source side is reflected back to the light guide panel to continuously generate reflection, refraction and scattering to enable the integral light guide panel to light uniformly through the arrangement of the transmitting openings, the hot spot phenomenon is avoided, the light utilization ratio is improved, and the backlight module and a liquid crystal displayer having good effect, high energy utilization ratio and narrow frames are produced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a side-entry reflector and a backlight module comprising the reflector. Background technique [0002] In a general liquid crystal display, the liquid crystal panel does not have a light-emitting function, so a backlight module is arranged below the liquid crystal panel to provide a surface light source to achieve the display function. Among the light sources of backlight modules, light emitting diodes (LEDs) are widely used due to their advantages of high luminous efficiency and high color gamut. Since the LED is a point light source, the luminous angle of its light-emitting surface is limited. Usually, in the backlight module of the liquid crystal display, multiple LEDs are arranged in a row to form an LED light bar to provide a line light source to the light guide plate, and then use the light guide plate to The line light source is converted into the surface li...
