Abstract
Disclosed are a liquid display device and a peep-proof control method thereof. The method includes: receiving and detecting a screen display signal required by the liquid crystal display device, and the screen display signal includes a brightness signal and a peep-proof signal; and in response to detecting that the peep-proof signal in the screen display signal is a partial peep-proof information, controlling a first switching timing of a backlight working state of a lamp panel in the liquid crystal display device to adapt to a second switching timing of a film working state of an electronically controlled liquid crystal film according to the brightness signal, so as to realize a partial peep-proof display of the liquid crystal display device.
