Abstract
An exemplary display device (200) includes a display module (230), a power supply circuit (240), a detecting circuit (210), and an anti-interfering circuit (250). The detecting circuit detects a predetermined type of radiation from an object near the display module. The anti-interfering circuit determines whether the radiation is from a potential user of the display device via identifying the frequency of the radiation and the time period that the radiation subsists. The power supply circuit provides power to the display module according to the identifying result.
