Problems solved by technology

As the optical path and the number of reflections of light in the light guide plate substrate increase, the cumulative absorption of light of a specific wavelength will continue to increase, which will cause the light intensity of light of a specific color to gradually decrease, resulting in The light intensity of the light of a specific color at different positions in the direction (the direction of backlighting in the text refers to the direction of illumination parallel to the bottom surface of the light guide plate) is quite different, which makes the chromaticity of the display screen deviate
Especially when applied to large-size LCD, the side-lit backlight module will cause serious chromaticity deviation in the display screen

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. It should be noted that "one" in the present invention is not used for quantitative limitation.

[0032] The invention provides a color shift balance film, a side-type backlight module and a liquid crystal display device. When the side-type backlight module is applied to the liquid crystal display device, the intensity difference of light at different positions along the backlight irradiation direction can be reduced. Effectively improve the problem of chromatic...

Abstract

The invention provides a color deviation balancing film, a lateral incidence type backlight module and a liquid crystal display (LCD) device. The color deviation balancing film is applied to the lateral incidence type backlight module and the thickness of the color deviation balancing film is reduced progressively along the backlight irradiation direction. The color deviation balancing film is arranged in the lateral incidence type backlight module. The lateral incidence type backlight module with the color deviation balancing film is arranged in the LCD device. When the lateral incidence type backlight module with the color deviation balancing film is applied to the LCD device, the intensity difference of light at different positions along the backlight irradiation direction can be reduced, and the color deviation generated by the display picture can be effectively improved.

Description

technical field [0001] The invention relates to the field of image display, in particular to a color shift balance film, a side-entry backlight module and a liquid crystal display device using the side-entry backlight module. Background technique [0002] With the continuous development of LCD (Liquid Crystal Display, liquid crystal display) display technology, LCD has been widely used in various display fields, and people's requirements for image quality displayed by LCD are also constantly increasing. [0003] Since the LCD itself does not emit light, the light quality of the LCD backlight module is particularly important. Compared with the traditional CCFL (Cold Cathode Fluorescent Lamp, Cold Cathode Fluorescent Lamp) backlight, LED (Light Emitting Diode, Light Emitting Diode) backlight has the advantages of high brightness and low energy consumption. Therefore, there are more and more LED backlight modules for liquid crystal display devices. [0004] LED backlight modu...
