Abstract
The invention discloses liquid crystal display television (LCD TV) energy saving device and method, wherein the device comprises an image detection device, a screen backlight control device and a screen driving device. The method includes the following steps: a, the image detection device detects the input image to judge whether the input image is a stationary image or a moving image; b, if the input image is a stationary image, the screen backlight control device sends a control signal to the screen driving device to reduce the backlight brightness of the screen and then outputs the image signal to the screen driving device; and c, if the input image is a moving image, the screen backlight control device directly transmits the image signal to the screen driving device. The LCD TV energy saving device and method can be applied in LCD TV sets and can reach effective energy saving effect by processing the moving images and the stationary images through different methods.
Description
Technical field
The present invention relates to liquid crystal tv technology, relate in particular to a kind of LCD TV energy saving device and method.
Background technology
The reception signal of liquid crystal TV set is divided into rest image and live image.The available liquid crystal televisor generally adopts identical disposal route to live image with rest image, if but play rest image for a long time, can waste electric energy, produce unnecessary expenditures.
Summary of the invention
The objective of the invention is to overcome the defective that exists in the above-mentioned prior art, propose a kind of LCD TV energy saving device and method.
The technical solution used in the present invention is, design a kind of liquid crystal TV set energy saver, comprise: an image detection device, screen backlight control apparatus and a panel drive device, after the picture signal input, image detection device at first carries out image detection to input signal, and when input picture was rest image, the screen backlight control apparatus sent control signal to panel drive device, reduce the screen backlight illumination, and then this picture signal is defeated by panel drive device; When input picture was live image, the screen backlight control apparatus directly flowed to panel drive device with picture signal.
The present invention has also designed a kind of liquid crystal TV set power-economizing method, comprises the following steps:
A. at first with image detection device input picture is detected, judge that input picture is rest image or live image;
B. when input picture was rest image, the screen backlight control apparatus sent control signal to panel drive device, reduced the screen backlight illumination, and then this picture signal is defeated by panel drive device;
C. when input picture was live image, the screen backlight control apparatus directly flowed to panel drive device with this picture signal.
The present invention is applied in the liquid crystal TV set, and live image is adopted different disposal routes with rest image, reaches energy-conservation purpose effectively.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples, wherein:
Fig. 1 is the structural representation of liquid crystal TV set energy saver of the present invention:
Fig. 2 is the process flow diagram of liquid crystal TV set power-economizing method of the present invention.
Embodiment
As shown in Figure 1, the liquid crystal TV set energy saver of the present invention's design comprises: an image detection device, screen backlight control apparatus and a panel drive device, after the picture signal input, image detection device at first carries out image detection to input signal, when input picture is rest image, the screen backlight control apparatus sends control signal to panel drive device, reduces the screen backlight illumination, and then this picture signal is defeated by panel drive device; When input picture was live image, the screen backlight control apparatus directly was defeated by panel drive device with picture signal.
As shown in Figure 2, the liquid crystal TV set power-economizing method of the present invention's design comprises the following steps:
A. at first with image detection device input picture is detected, judge that input picture is rest image or live image;
B. when input picture was rest image, the screen backlight control apparatus sent control signal to panel drive device, reduced the screen backlight illumination, and then this picture signal is defeated by panel drive device;
C. when input picture was live image, the screen backlight control apparatus directly flowed to panel drive device with this picture signal.
In one embodiment of the invention, the screen backlight control apparatus adopts the MCU microprocessor.When televisor shows that the same painting face time surpassed for 1 second, can think rest image.After this picture signal input, image detection device judges that this signal is rest image.At this moment, the screen backlight control apparatus sends control signal to panel drive device, and backlight illumination is turned down, and then, again this signal is flowed to panel drive device; Otherwise, when image detection device judges that input signal is live image, this signal directly can be flowed to panel drive device, keep backlight illumination.
In the method for the present invention's design, after the picture signal input, carry out picture signal earlier and detect, then by master chip monitoring picture material, when monitoring rest image when occurring, MCU sends control signal, make the screen backlight controller reduce the screen backlight illumination, play energy-conservation effect.
The present invention automatically adjusts to backlight illumination, under the situation that the user does not discover, plays energy-conservation effect.And when the user watches live image, automatically restore to normal backlight illumination, do not influence user's the effect of watching.
Though the present invention is described with reference to above-mentioned embodiment; but those skilled in the art will be appreciated that; above-mentioned embodiment only is used for illustrating the present invention; be not to limit protection scope of the present invention; any within the spirit and principles in the present invention scope, any modification of doing, equivalence are replaced, are improved and all should be included within the scope of the present invention.
