Abstract

The invention discloses a light source module, a backlight module and a display module. The light source module comprises a circuit board, at least one light-emitting component, at least one optical lens and a light adjusting layer. The at least one light-emitting component is arranged on the circuit board; the at least one optical lens is located on the circuit board, and each optical lens covers one light-emitting component; the light adjusting layer is arranged on the circuit board, and at least one optical adjusting area is formed at the position, corresponding to each light-emitting component, of the light adjusting layer; the light adjusting layer has a first reflectivity in the at least one optical adjusting area and a second reflectivity outside the at least one optical adjusting area, and the first reflectivity is greater than the second reflectivity. According to the invention, the light emitting angle of the optical lens corresponding to each light emitting component is enlarged, the phenomenon of dark bands between every two adjacent light emitting components can be avoided, the light uniformity of the backlight module is improved, and the display effect of the display module is improved.

Description

technical field [0001] The invention relates to a light source module, a backlight module and a display module, in particular to a light source module, a backlight module and a display module for improving light uniformity. Background technique [0002] With the continuous development of liquid crystal display technology, the requirements for the backlight module supplying the light source of the liquid crystal display panel are also getting higher and higher. In the traditional direct-lit backlight module, the light spot illuminance range of the light-emitting component is narrow, and the light intensity distribution angle is small. Especially when it is used with a quantum dot film or quantum dot plate, the light generated by the light-emitting component is relatively more effective for the excitation of quantum dots. Limitation, from the picture effect, it is easy to have local color difference, which will affect the display effect. Contents of the invention [0003] T...
