Benefits of technology
The present patent provides a display device that includes a liquid crystal prism which adjusts the deflection angle of light emitted from a backlight source to direct it towards the display device at an oblique angle. The liquid crystal prism can have a first operation state in which the light is incident on the display device at an angle greater than or equal to the total reflection critical angle, a second operation state in which the light is incident on the display device at an angle less than the total reflection critical angle, and a third operation state in which one part of the light is incident on the display device at an angle greater than the total reflection critical angle and another part of the light is incident on the display device at an angle less than the total reflection critical angle. The display device can also include a backlight source arranged to face the second substrate away from the first substrate. The invention provides a display method using the display device, which includes directing the light emitted from the backlight source towards the display device at an oblique angle and controlling the liquid crystal prism to adjust the deflection angle of the light. The technical effects of the invention include improved display quality and energy efficiency.

A display device and a display method using the same are disclosed. The display device includes: a display panel including a first substrate, a second substrate and a liquid crystal prism arranged between the first substrate and the second substrate; and a backlight source configured to emit a light which is incident onto the second substrate at an oblique angle; wherein the liquid crystal prism is configured to adjust a deflection angle of the light emitted from the backlight source traveling between the first substrate and the second substrate such that the light emitted from the backlight source is totally-reflected at a light exit face of the display device or exits from the light exit face of the display device.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims benefit of the Chinese Patent Application No. 201710035757.8, filed with the State Intellectual Property Office of China on Jan. 18, 2017, which is incorporated herein by reference in its entirety.BACKGROUND OF THE DISCLOSUREField of the Disclosure[0002]The present disclosure relates to the technical field of liquid crystal display, and in particular, to a display device and a display method.Description of the Related Art[0003]At present, liquid crystal display devices have been widely used in people's lives.[0004]In the conventional liquid crystal display device, the liquid crystal is used to modulate polarization of a linearly polarized light to change the polarization orientation of the linearly polarized light, so as to display pictures in different states, that is, grey scale display. Thus, in the conventional liquid crystal display device, polarizer sheets need to be provided on two substrates of the display p...
