In addition to Lu method

The invention provides a dew removing method, which is used for removing dew in a display device. Dew is condensed between a display panel and a transparent plate of the display device. The dew removing method comprises the following steps: receiving touch operation executed on the transparent plate; deciding a first region on the display panel according to the touch operation in order that the projection of dew on the display panel is positioned in the first region; deciding a second region on the display panel in order that the second region includes the first region and extends to the side edge of the display panel and that the ventilation opening of the display device is close to the second region and is positioned above the second region; enhancing the light emitting intensity of the display panel in the second region. By adopting the dew removing method, the dew evaporation rate in a corresponding region is increased.
