Abstract

The invention discloses a direct-descend type LED light source module, a backlight module and a display panel. The direct-descend type LED light source module comprises a transparent base material, an LED light source and a reflector element of a sunken face structure on one side in the direction of the LED light source; the LED light source is arranged on one side of the transparent base material in the direction of the reflector element and is located at the focus point of the reflector element, a spread structure is arranged on the internal side of the transparent base material and / or the surface of the transparent base material; the reflector element is the Fresnel reflector. By the direct-descend type LED light source module, before the ray of light gets into a diffuser plate, pre-homogenizing treatment is conducted on the LED light source by the reflector element, hence, low haze diffuser plates can be worked with, and light issuing efficiency is further increased. In addition, because the light source shows the parallel light after the reflection, the proportion of light diffused to a larger viewing angle is lowered, the light intensity facing squarely the angle can be improved, and the spread structure arranged on the transparent base material offsets the rays of light stopped by the fixing point of the LED light source. Hence, by the direct-descend type LED light source module, the brightness of the display can be improved by design, and the energy-saving effect is achieved.

Description

technical field [0001] The invention belongs to the field of LED light sources, and in particular relates to a direct-lit LED light source assembly, a backlight module and a display panel. Background technique [0002] Liquid crystal displays are mainly divided into direct-type and side-type designs due to the difference in the position of the light source. In the direct light source backlight module, it is necessary to use a fog diffuser plate to atomize the LED point light source to obtain a uniform surface light source. [0003] General direct type LED light source design such as figure 1 1. The LED light source 12 is installed on the circuit substrate 11, and the support frame 13 and the lens top cap 14 are arranged thereon in sequence. With such a light source design, after the LED emits light, the light directly diverges upwards and enters the optical film group and the liquid crystal module, forming a complete direct-lit backlight system. [0004] Under this struct...
