[0104] Please refer to image 3 , which shows a schematic diagram of the liquid crystal display device 100 according to the first embodiment of the present invention. The liquid crystal display device 100 includes a backlight module 110 , a display panel 120 , a first polarizer 130 and a second polarizer 140 . The backlight module 110 has a light emitting surface 110a. The backlight module 110 includes a light emitting component 111 , a polarizing component 112 and a modulating component 116 . The light emitting component 111 is used for providing a light source. After the light source passes through the polarizing component 112, the first polarized light L11 is formed. The modulation component 116 has a plurality of modulation regions 116a. Each modulation area 116a corresponds to a modulation direction C1 or C2. After passing through the modulation regions 116a, the first polarized light L11 forms a plurality of second polarized lights L12, which are emitted from the lig...

[0119] The difference between the liquid crystal display device 200 of this embodiment and the liquid crystal display device 100 of the first embodiment lies in the polarizing component 212 of the backlight module 210 , and the rest of the similarities will not be repeated here. Please refer to Figure 9 , which shows a schematic diagram of the liquid crystal display device 200 of the second embodiment. In this embodiment, the first polarized light L11 is in a linearly polarized state, and the modulation component 116 corresponds to a phase difference of 1 / 2 wavelength. The polarizing component 212 includes a circular polarizing plate 215 and a linear modulating plate 214 . Wherein, the circular polarizer 215 has a brightness enhancement film 213 .

[0120] When the light source passes through the circular polarizing plate 215, the light source forms the first polarized light L11 in a circularly polarized state. At the same time, the brightness enhancement film 213 can refl...

[0124] The difference between the liquid crystal display device 300 of this embodiment and the liquid crystal display device 100 of the first embodiment lies in the modulating component 316 and the polarizing component 312 of the backlight module 310 , and the rest of the similarities will not be repeated here. Please refer to Figure 10 , which shows a schematic diagram of the liquid crystal display device 300 of the third embodiment. In this embodiment, the first polarized light L31 is circularly polarized, and the modulation component 316 corresponds to a phase difference of 1 / 4 wavelength or 3 / 4 wavelength. The polarizer assembly 312 includes a circular polarizer 315 . The circular polarizing plate 315 has a brightness enhancement film 313 .

[0125] When the light source passes through the circular polarizing plate 315 , the light source forms the first polarized light L31 of the circular polarization state 315 . At the same time, the brightness enhancement film 313 ca...

Abstract

The invention provides a liquid crystal display device as well as a backlight module thereof and a display method. The backlight module at least includes a lighting component, a polarization component and a modulation component. The lighting component is used for providing a light source. A first polarized light is formed after the light source passes through the polarization component. The modulation component is provided with a plurality of modulation areas. Each modulation area corresponds to one modulation direction, and a plurality of second polarized lights are formed after the first polarized light passes through the modulation areas. The second polarized lights respectively correspond to the modulation directions, wherein the modulation directions are not identical.

Description

technical field [0001] The present invention relates to a liquid crystal display device, its backlight module, and a display method, and in particular to a liquid crystal display device, its backlight module, and a display method that use a modulating component in combination with a polarizing component so that light sources can present different shades when entering a display panel. . Background technique [0002] Display technology is changing with each passing day, bringing people unlimited visual enjoyment. In particular, liquid crystal display devices have the advantages of small size, light weight, high image quality, and long life, making liquid crystal display devices widely used in various electronic products, such as digital televisions, computer screens, notebook computers, mobile phones or cameras. [0003] Please refer to FIG. 1 , which shows a schematic diagram of a conventional liquid crystal display device 900 . The liquid crystal display device 900 include...
