Abstract

Embodiments of the present invention provide a backlight source module, and relate to the display technology field. A high color gamut light source or a high luminous efficiency common color gamut light source can be flexibly selected according to user need, high quality visual enjoyment of users is guaranteed, power consumption of the back light module is reduced, and energy is saved. The backlight source module comprises a light guide plate and light sources disposed at side portions of the light guide plate; the light sources comprise a first light source set and a second light source set; the first light source set is a high color gamut light source; the second light source set is a high luminous efficiency common color gamut light source; and the light guide plate can convert line light sources emitted by the first light source set and the second light source set into area light sources. The backlight source module is applied to a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight source module. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) is a semiconductor optoelectronic device that can convert electrical energy into light energy. Provide a light source. With the continuous improvement of people's requirements on the performance of display devices, high color gamut LEDs and high luminous efficacy LEDs have become the focus of people's attention. [0003] The color gamut is an indicator to measure the color performance capability of a display device. The larger the color gamut, the richer the colors that can be displayed on the display screen, and the more colorful the colors will be. Generally, a color gamut of about 72% NTSC (National Television Standars Committee, National Television Standards Committee) is an ordinary color gamut, and a color gamut of 90% NTSC (National Television Standars Committee, Na...
