Abstract

The invention discloses a lateral-emission type backlight module and a display device. The lateral-emission type backlight module includes a back plate, a reflecting sheet, a back light source and a light guide plate, wherein the reflecting sheet is arranged between the back plate and the light guide plate, the light guide plate comprises a first light guide layer, PET plates and a second light guide plate which are sequentially arranged in a laminated mode, the first light guide layer is arranged closely to the reflecting sheet, the back light source is arranged closely to the lateral surfaceof the first light guide layer, and the refractive indexes of the transparent PET plates are higher than those of the first light guide layer and the second light guide layer. Light energy can enterthe PET plates from the first light guide layer without total reflection and almost completely enter the middle PET plate, and therefore the utilization rate of the light energy is greatly increased,and the cost consumption caused by illuminance enhancement is reduced.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to an edge-in type backlight module and a display device. Background technique [0002] Liquid crystal displays have the advantages of lightness and thinness, and have been widely used. Backlight modules are devices that provide light sources for liquid crystal displays. Backlight modules are divided into direct-type backlight modules and side-type backlight modules according to the location of the light source. Group. The side-entry backlight module is composed of a backplane, a middle frame, a reflector, a light guide plate, a diaphragm, and an LED light bar. Among them, the LED light bar is a line light source, and its light energy needs to be converted into a surface light source through the light guide plate and the dots at the bottom. The commonly used material of the light guide plate is PMMA (polymethyl methacrylate), etc. From a theoretical analysis, its refractive index...
