Abstract

The embodiment of the invention provides an adjustable polarization device, a method and a display device of the adjustable polarization device, and relates to the technical field of display. By means of the special design of the polarization device, different voltage signals can be input into the polarization device, and the display device can be switched between a common mode and an anti-peeping mode. The adjustable polarization device comprises a first conductive layer, a first polarization layer arranged on the first conductive layer, a second polarization layer arranged on the first polarization layer and a second conductive layer arranged on the second polarization layer, wherein the first conductive layer and the second conductive layer are respectively connected with a power supply, and the first polarization layer is made of electro-optic crystals.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an adjustable polarization device, a method thereof, and a display device. Background technique [0002] With the continuous advancement of display technology, users have further demands on the functions of the display device, and the anti-peeping display technology that can prevent other people from viewing the displayed information has attracted people's attention. The anti-peeping display device can only see the displayed images for people with anti-peeping glasses, but cannot see the displayed images for people without anti-peeping glasses, thereby achieving the purpose of protecting personal information and commercial information. [0003] Existing display devices can only have a single anti-peeping display or normal display (non-peeping-proof display), but in different application scenarios, it is necessary to switch between the two modes, but the existing technology is no...
