Abstract
An anti-peep module including an anti-peep element, a driving circuit, a voltage adjustment circuit and a temperature sensor is provided. The anti-peep element includes a liquid crystal layer, a first anti-peep electrode layer and a second anti-peep electrode layer. The liquid crystal layer is located between the first and second anti-peep electrode layers. The temperature sensor is adapted to sense an ambient temperature. The voltage adjustment circuit is coupled to the temperature sensor. The driving circuit is coupled to the voltage adjustment circuit and the anti-peep element. When the ambient temperature is a first ambient temperature and the anti-peep element operates in an anti-peep mode, the driving circuit outputs a first driving voltage to the anti-peep element; when the ambient temperature is a second ambient temperature and the anti-peep element operates in the anti-peep mode, the driving circuit outputs a second driving voltage to the anti-peep element.
