Abstract
The invention discloses an energy-saving display, which comprises a power supply module, a mainboard, a display screen, a signal input module, a step-up circuit, a control circuit microprocessor, and a voltage regulator, wherein the step-up circuit is connected with the display screen; the power supply module is connected with the mainboard and the step-up circuit respectively; an information input module transmits a signal to the display screen through the mainboard; and the power supply module, the control circuit microprocessor, the voltage regulator and the mainboard are connected in series in turn. Provided with the control circuit microprocessor and the voltage regulator, the energy-saving display can control the mainboard to work, so the display can automatically achieve the aim of reducing the energy consumption in a shutdown state.
Description
Technical field
The present invention relates to a kind of display, is a kind of energy-efficient display specifically.
Background technology
Display function in the market is many, for close environment, energy-conservation reverse side requires more and more higher, but existing display as shown in Figure 1, it comprises power module, mainboard, display module, the loop of boosting, and wherein power module provides DC voltage to loop and the mainboard of boosting; Handle and provide on-screen-display message to the received signal by the central processing element on the display main board; Display module provides operating voltage by the loop of boosting, and receives signal and demonstration that central processing element provides simultaneously; Because the on off state of display can't be preserved on mainboard,,, preserved with the on off state that guarantees display by the power supply of control loop control main board so need external control loop.Existing display need be turned off mainboard voltage by the external world, could control the energy consumption of display.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide a kind of display and under off-mode, reach energy-conservation energy-efficient display automatically.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of energy-efficient display, comprise power module, mainboard, display screen, signal input module, the loop of boosting that links to each other with display screen, power module joins with mainboard, the loop of boosting respectively, MIM message input module transfers to display screen by mainboard with signal, described display also comprises control loop, and described power module, control loop and mainboard are connected in series successively.
Described control loop comprises control loop microprocessor, voltage adjuster, and described power module, control loop microprocessor, voltage adjuster and mainboard are connected in series successively.
Among the present invention, power module is given the display screen operating voltage with a power supply part by the loop of boosting, a part is given main board power supply in addition, the duty of control loop microprocessor judges display then, if display is in running order, then voltage adjuster is given the mainboard output voltage, and mainboard is started working, and display is energy-conservation less than 0.5W after shutdown; If display is in off position, then voltage adjuster is not given the mainboard output voltage, and mainboard is not worked yet, and at this moment display still is in power save mode, and this moment is energy-conservation less than 0.5W.
Compared with prior art, increased control loop microprocessor, voltage adjuster among the present invention, this is the work of energy control main board just, thereby can make display reach the purpose that cuts down the consumption of energy automatically under off-mode.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a workflow diagram of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of energy-efficient display of the present invention, comprise power module, mainboard, display screen, signal input module, the loop of boosting that links to each other with display screen, power module joins with mainboard, the loop of boosting respectively, MIM message input module transfers to display screen by mainboard with signal, described display also comprises control loop microprocessor and voltage adjuster, and described power module, control loop microprocessor, voltage adjuster and mainboard are connected in series successively.
As shown in Figure 3, power module provides operating voltage by the loop of boosting to screen with power supply, duty by control loop microprocessor judges display, the user directly provides the switch that high-low level is realized voltage adjuster on the mainboard by operating key, voltage adjuster is opened, then mainboard is not worked, and voltage adjuster cuts out, and then mainboard is started working.
The above only is a preferred implementation of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
