Abstract:
1. A display device capable of synchronously controlling an environmental light, comprising: an image display module which is used to display a multimedia image; a control module which is electrically connected to the image display module generating electrical signals and generates a first light source control signal or a second light source control signal in response to a synchronization signal, wherein the synchronization signal is a V-sync signal and generated during a plurality of odd frames where a backlight module is switched on and even frames where the backlight module is switched off, the odd frames and the even frames alternate in temporal order, the control module generates the first light source control signal to control the environmental light to operate at a turn-on state during the odd frames, and the control module generates the second light source control signal to control the environmental light to operate at a turn-off state during the even frames where the backlight module is switched off; and a signal transmission module which is electrically connected to the control module and transmits the first light source control signal and/or the second light source control signal; wherein the environmental light is capable of illuminating the image display module and the control module responds to the plurality of even frames to generate an inserted black frame so that the image display module displays a black frame.
