At present, in a liquid crystal display panel, it is often necessary to control the rotation of liquid crystal molecules by an electric signal. For an ADS (Advanced Super Dimension Switch) liquid crystal panel, because the pixel electrode and the common electrode are not in the same plane, the fringe electric field formed between the pixel electrode and the common electrode is often used to control the rotation of the liquid crystal molecules. However, the non-uniformity of the fringe field and the Rubbing easily cause the pre-tilt angle of the liquid crystal molecules, which leads to the light leakage in the dark state of the display device, and the problems of low contrast ratio, color shift in the dark state, etc. For this reason, the prior art has improved the above problem by attaching two layers of liquid crystal together.
However, the double-layer liquid crystal absorbs more blue light, which eventually reduces the color temperature of the display device, resulting in a reduction in the quality of the display screen.
Therefore, the color temperature of the display device is very low due to the existing double-layer liquid crystal.

In a specific implementation process, a blue light compensation part 40 including a blue light enhancement film and/or a yellow-green light absorption film may be specifically disposed in the backlight module 20, and in this case, the blue light compensation part 40 is an optical film for increasing a blue component.
In an implementation, the backlight module 20 includes a Light Emitting Diode (LED) and a Light guide plate, and the blue Light compensation part 40 may be disposed on a surface of the LED or on a surface of the Light guide plate. It is also possible to dispose the blue light compensating part 40 on both the surface of the LED and the surface of the light guide plate.

Specifically, the blue light compensation part 40 is attached to the surface of the LED and/or the surface of the light guide plate.

In the embodiment of the invention, the content of benzene rings in the liquid crystal material in any liquid crystal box is less than a preset value. For example, the preset value is the content of benzene ring in the liquid crystal cell of the existing display device, or the value set by one skilled in the art according to the actual requirement for the blue light transmittance. Once the content of the benzene ring is reduced, the refractive index of the corresponding liquid crystal box is also reduced, so that the blue light transmittance is improved, and the color temperature of the display device is improved. In the specific implementation process, a person skilled in the art can adjust the benzene ring content in the corresponding liquid crystal cell according to the actual requirement on the blue light transmittance of the display device. For example, when the content of the benzene ring in the liquid crystal cell a is a, the content of the benzene ring in the liquid crystal cell a is reduced by 1% on the basis of a, the content of the benzene ring in the adjusted liquid crystal cell a is 0.01a, and the refractive index of the adjusted liquid crystal cell a is reduced by 0.008, so that the blue light transmittance of the display device is improved.
In the implementation process, the content of the benzene ring in each liquid crystal cell in the display device may be specifically adjusted to be smaller than the preset value, or the content of the benzene ring in at least one liquid crystal cell in the display device may be adjusted to be smaller than the preset value. Of course, those skilled in the art can adjust the benzene ring content in the liquid crystal cell according to the actual requirement of the blue light component in the display device, and the details are not repeated here.
In the embodiment of the present invention, a person skilled in the art can use a combination of various schemes provided in the present invention to adjust the blue transmittance of the display device according to the actual requirement of the blue transmittance of the display device, for example, at the same time when the backlight module 20 and the at least one polarizer 30 are attached to the blue light compensation portion 40 of the film layer structure, a pigment or a dye for increasing the blue light component is filled in any film layer of any polarizer, and the content of the benzene ring in any liquid crystal cell is reduced, which will not be described in detail herein.
