Abstract

The invention provides a backlight module. The backlight module comprises a back plate; a containing space is formed in the back plate; a light adjusting assembly is contained in the containing spaceand used for guiding in and sending out the near natural light emitted by an LED light source; the relative spectral power of red light in the near natural light is larger than 0.60; the relative spectral power of cyan light is larger than 0.30; the relative spectral power of blue light is smaller than 0.75; and the color rendering index Ra of the near natural light is larger than 90, the color rendering index R9 is larger than 90, and the color rendering index R12 is larger than 80. Through the backlight module provided by the invention, the LED light source which can emit the near natural light is adopted, the complete spectrum is achieved, and the near natural light is formed, wherein the color rendering index Ra is larger than 90, the color rendering index R9 is larger than 90, the color rendering index R12 is larger than 80, and thus the color of a displaying area is more vivid. Meanwhile, the eyesight is protected advantageously through reduction of blue light, and eye fatigue isprevented; and besides, the red light is improved, and the health grade of electronic products such as mobile phones is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and more specifically relates to a backlight module. Background technique [0002] The backlight module is used to provide backlight in the display screen, such as in electronic products such as computers and IPads. The brightness and uniformity of the existing backlight modules have been continuously improved, but the color of the image is still improving slowly, which is mainly reflected in the fact that the authenticity of the color of the image needs to be improved. Existing backlight modules usually use a high color temperature backlight, which can improve the contrast to a certain extent, but still cannot ideally reflect the true color of any scene, and some local scenes are difficult to truly present. Contents of the invention [0003] The purpose of the present invention is to provide a backlight module, aiming at improving the color rendering of the backlight module and preventing im...
