A display device includes a casing, a display panel, a transparent plate, a fan, a humidity sensor, a first temperature sensor, a second temperature sensor and a processing unit. The casing includes a front bezel with an opening. The display panel is disposed on a first side of the opening and the transparent plate is disposed on a second side of the opening such that a space is formed between the display panel and the transparent plate. The humidity sensor is configured for sensing a humidity of the space. The first temperature sensor is configured for sensing a first temperature of the space. The second temperature sensor is configured for sensing a second temperature of the transparent plate. When the processing unit determines that the humidity, the first temperature and the second temperature meet a predetermined relationship, the processing unit increases a rotational speed of the fan.
