Abstract
Official abstract text for this publication.
A display device capable of controlling an external light and a control method are provided. Image display of the display device and the external light are synchronously controlled through a synchronization signal generated by a control module in the display device. The control module generates a first and a second light source control signal during first cycles and second cycles of the synchronization signal. The first and the second light source control signal are used to control the external light to operate at a first operation state and at a second operation state respectively. Through the techniques of controlling the external light by the display device, i.e. turning off or reducing illumination intensity of the external light every other specific period, both influence of the external light on contrast ratio and light reflection from the display device are reduced. Power of the external light is also saved.
First claim
Opening claim text (preview).
What is claimed is: 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 gener…
