Abstract
The present disclosure discloses a mask, which includes a first substrate and a second substrate. The mask further includes a polarity particle positioned between the first substrate and the second substrate. The polarity particle has a light absorption or light transmission effect. The first substrate includes a plurality of driving electrodes disposed toward the second substrate and arranged in an array. Each of the driving electrodes is configured to receive an electric signal and control the polarity particle to move to a designated driving electrode to form a pattern.
