[0081] 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 polarizing plate 130 and a second polarizing plate 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 modulation component 116. The light emitting component 111 is used to provide 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 the first polarized light L11 passes through the modulation regions 116a, a plurality of second polarized lights L12 are formed and emitted from the light em...

[0096] 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 remaining similarities are not repeated here. Please refer to Picture 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 linearly polarized, and the modulating component 116 corresponds to a 1 / 2 wavelength phase difference. The polarizing component 212 includes a circular polarizing plate 215 and a linear modulating plate 214. Among them, the circular polarizing plate 215 has a brightness enhancement film 213.

[0097] After the light source passes through the circular polarizing plate 215, the light source forms the first polarized light L11 in a circular polarization state. At the same time, the brightness enhancement film 213 can reflect the light sou...

[0101] 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 modulation component 316 and the polarizing component 312 of the backlight module 310, and the rest of the similarities will not be repeated. Please refer to Picture 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 in a circular polarization state, and the modulation component 316 corresponds to a phase difference of 1 / 4 wavelength or 3 / 4 wavelength. The polarizing component 312 includes a circular polarizing plate 315. The circular polarizing plate 315 has a brightness enhancement film 313.

[0102] When the light source passes through the circular polarizing plate 315, the light source forms the first polarized light L31 in the circular polarization state 315. At the same time, the brightness enhancement film 31...

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, a backlight module and a display method thereof, and more particularly to a liquid crystal display device with a modulating component and a polarizing component so that when a light source enters a display panel, a liquid crystal display device with different brightness and darkness, a backlight module and a display method thereof . Background technique [0002] Display technology changes with each passing day, bringing people unlimited visual enjoyment. In particular, the liquid crystal display device has the advantages of small size, light weight, high image quality and long life span, which makes the liquid crystal display device 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 liqui...
