Abstract

The invention relates to a light source assembly and a preparation method thereof. A driving substrate is provided with a first surface; the plurality of light-emitting elements are arranged on the first surface and are electrically connected to the driving substrate; the reflecting layer is coupled to the area, not provided with the light-emitting elements, of the first surface, the reflecting layer comprises a plurality of light-emitting reflecting parts, and the light-emitting reflecting parts are correspondingly arranged around each light-emitting element; and the plurality of light-emitting reflection parts are configured to be arranged in a manner of protruding outwards relative to the first surface, so that a plurality of cavities which are mutually spaced are formed between the light-emitting reflection parts and the first surface. Due to the fact that the reflecting layer is provided with the light-emitting reflecting part protruding outwards, the reflecting layer is provided with an uneven rough surface, light emitted by the light-emitting element irradiates the reflecting layer and then becomes diffuse reflection, and the utilization rate of a light source is improved. The invention further provides a backlight module and a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light source component, a preparation method thereof, a backlight module and a display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of small size, low power consumption, and no radiation, and is widely used in various electronic devices. The LCD display device includes an LCD panel and a backlight module for providing light to the LCD panel. The backlight module is divided into direct-type and side-type. Compared with the side-type, the direct-type backlight module does not need a light guide plate and has higher light conductivity. [0003] However, the light source assembly in the direct type backlight module in the existing design still has the problem of low light source utilization. Contents of the invention [0004] Based on this, it is necessary to provide a light source assembly and its preparation method, a backlight module ...
