Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Such as figure 1 As shown, the structure of the backlight module in this embodiment includes: a light guide plate 1 , a diffusion sheet 2 , a prism sheet 3 , a prism sheet 4 , and a diffusion sheet 5 . There is an LED Bar on both sides of the light guide plate 1, and the LED Bar is provided with a white light source 11 (white-emitting LED) and N primary colors (such as: three primary colors red, green, blue RGB, four primary colors CMYK or other custom color systems) ) monochromatic light source 12 of at least one color. In order to mix the light sources evenly, the white light sources 11 and the monochrome light sources 12 are arranged at intervals.

Abstract

The invention relates to the technical field of display, and discloses a backlight module, which comprises a light guide plate and light strips which are arranged on the light guide plate, wherein the light strips are provided with white light sources; the backlight module is characterized in that the light strips are also provided with monochromatic sources of at least one color in N preset primary colors; and N is greater than or equal to 1. The invention also discloses a display device comprising the backlight module. The monochromatic sources are embedded into the LED (Light Emitting Diode) light strips, so that the color gamut representation range of the LED backlight display system is improved, the size of a sub-pixel point is required to be changed in order to be matched with a special backlight source for use, and the phenomenon of color distortion is avoided while the color gamut range of the display system can be improved and the color presentation is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Liquid crystal display devices have become the mainstream of display devices, and are mainly used in liquid crystal displays for computers, large-size LCD TVs, and the like. Since the liquid crystal panel itself cannot emit light, it needs to be used in conjunction with a backlight source to achieve a display effect. In the early stage of liquid crystal display equipment development, the mainstream backlight was CCFL (Cold Cathode Fluorescent Lamp), but the mechanical strength of CCFL was insufficient, the expressiveness of color was not good, and it contained mercury, which did not meet the environmental protection requirements. In recent years, LED backlights have gradually replaced the use of CCFL backlights. It should be because compared with CCFL backlight, LED has many advantages: no toxic substances,...
