Abstract

The inention discloses adirect type ultrathin backlight module, which comprises a circuit board, a first reflecting layer, an optical layer, a second reflecting layer and a functional layer which are sequentially arranged from bottom to top; the circuit board comprises a base material and a conductive circuit located on the base material; an LED lamp in the first reflecting layer is embedded into the optical layer; the bottom of the LED lamp is electrically connected with the conductive circuit; and a plurality of light emitting holes are formed in the second reflecting layer. By the adoption of the direct type ultrathin backlight module, the light emitting effect is guaranteed, and meanwhile, the whole ultrathin structure is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic materials, in particular to a direct-type ultra-thin backlight module. Background technique [0002] Backlights are divided into direct-lit backlights and edge-lit backlights according to the position of the light source. Direct-type backlight, the LED light source is directly placed under the light-emitting surface, the light emitted by the light source is diffused and mixed by a certain space distance and the diffusion plate, and then becomes a surface light source to be emitted. The direct-type backlight requires a certain light mixing distance. The side-lit backlight is to arrange LED lights on the side of the light guide plate, and achieve the effect of surface light through the design of the light guide plate. Its advantage is light and thin, but its heat dissipation and local light control problems have always been problems in the industry. [0003] With the market's pursuit of higher i...
