Embodiment Construction

[0037] Hereinafter, embodiments of the image display device and its power saving control method of the present invention will be described in detail with reference to the drawings. To facilitate understanding, the same components in the following embodiments are indicated by the same symbols.

[0038] figure 1 It is a schematic diagram of an embodiment of the image display device of the present invention. Such as figure 1 As shown, the image display device 1 includes a signal input module 11, a display module 12, a light emitting module (not shown), and a control module 14. The signal input module 11 is used to receive an image signal 111, such as an image signal from a computer, or a TV signal from a TV set-top box, and so on. The signal input module 11 may include multiple signal interface connectors, such as a VGA connector, an AV terminal, or a DVI connector.

[0039] The light-emitting module is used to provide light for the display module 12, and the display module 12 pro...

Abstract

The invention discloses an image display device and a power-saving control method thereof. The image display device comprises a signal input module, a display module, a light-emitting module and a control module, wherein the signal input module is used for receiving an image signal; the display module is used for displaying an image according to the image signal; the light-emitting module is provided with a plurality of light sources and used for providing rays of the display module; and the control module selectively lightens or turns off the part of light sources according to the property of the image signal and enters the power-saving mode, therefore, the invention can achieve the efficacy of prolonging the service life of a backlight source and saving the power consumption of the display device.

Description

Technical field [0001] The present invention relates to an image display device and a power-saving control method thereof, and in particular to an image display device that can turn off part of the light source of the image display device according to an image display area and a power-saving control method thereof. Background technique [0002] As environmental issues are getting more and more attention, how to enable electronic devices to save power consumption is currently the most noticed technical field. There are many technologies to save the power consumption of the computer, but there is almost no effective power saving on the traditional display device, and the user can only rely on the user to manually turn off the screen when not in use. However, if the user neglects to turn off the screen when leaving, the screen will continue to display and consume power. [0003] At present, the automatic judgment function related to the screen is only the screen saver function. When...
