Abstract
The invention discloses an energy saving method for a liquid crystal display. A control module is connected in series between a light guide plate and a power supply of the liquid crystal display, is connected with an external cage calling system, reduces the driving current of the light guide plate in the absence of a calling landing signal, and regulates the driving current to be recovered to normal magnitude in the presence of the calling landing signal. The energy saving method is simple in structure; the driving current of the light guide plate is reduced to reduce heat under the condition of no calling landing signal, so that the brightness of the whole liquid crystal display is reduced, energy is saved, and the service life of the display is prolonged; and the liquid crystal display is recovered to normal brightness to facilitate the observation of a user in the presence of the calling landing signal.
Description
A kind of power-economizing method of liquid crystal display
Technical field
Existing liquid crystal display in use is under the normal brightness condition always, and use procedure expense electricity is against the sustainable development idea.
Background technology
The present invention relates to a kind of power-economizing method of liquid crystal display.
Summary of the invention
The technical problem to be solved in the present invention is that existing liquid crystal display usage charges electric weight is large.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of power-economizing method of liquid crystal display, be in series with control module between the light guide plate of described liquid crystal display and the power supply, this control module is connected with the car call system of peripheral hardware, when not having calling signal, control module reduces the drive current of light guide plate; When calling signal was arranged, control module was regulated drive current and is recovered normal size.
As a kind of improvement project of the present utility model, when not having calling signal, the drive current of light guide plate is 1/3rd of running current size.
Advantage of the present invention is: simple in structure, under the condition without calling signal, reduce the drive current size of light guide plate, and reduce heating, whole LCD brightness is reduced, energy-conservation and prolonged display serviceable life, when being arranged, recovers calling signal normal brightness, and make things convenient for the user to observe.
Description of drawings
Fig. 1 is the invention structural representation.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the power-economizing method of a kind of liquid crystal display of the present invention, be in series with control module 2 between the light guide plate of described liquid crystal display 1 and the power supply 3, this control module 2 is connected with the car call system of peripheral hardware, when not having calling signal, control module 2 reduces the drive current of light guide plate to 1/3rd of light guide plate working current; When calling signal was arranged, control module 2 was regulated drive current and is recovered normal size.
During use, liquid crystal display 1 brightness meeting in the no signal situation reduces by 1/3rd, once receive calling signal, namely recovers normal brightness.
Claims (2)
1. the power-economizing method of a liquid crystal display, it is characterized in that: be in series with control module between the light guide plate of described liquid crystal display and the power supply, this control module is connected with the car call system of peripheral hardware, and when not having calling signal, control module reduces the drive current of light guide plate; When calling signal was arranged, control module was regulated drive current and is recovered normal size.
2. the power-economizing method of a kind of liquid crystal display according to claim 1, it is characterized in that: when not having calling signal, the drive current of light guide plate is 1/3rd of running current size.
