Abstract
The invention discloses an energy saving method of a lattice display. The lattice display comprises a plurality of LED units connected in parallel. Each LED unit is composed of a plurality of LEDs connected in parallel, a control module is in series connection between one LED and a power supply, and the control module is connected with an external car calling system. The lattice display is simple in structure. Not all the LEDs are lit under no call signals, and accordingly brightness of the whole lattice display is reduced, energy is saved, and the service life of the lattice display is prolonged. All the LEDs are lit when a call signal exists, and accordingly a user observes conveniently.
Description
Technical field
Existing matrix 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 matrix display.
Summary of the invention
The technical problem to be solved in the present invention is that existing matrix 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 matrix display, described matrix display comprises LED unit a plurality of and that connect, each LED unit is by a plurality of LED and connect composition, and wherein have between a LED and the power supply and be serially connected with control module, this control module is connected with the car call system of peripheral hardware, judges whether to exist calling signal by control module; When not having calling signal, be in series with all not conductings of LED of control module, remaining LED conducting; When calling signal is arranged, the equal conducting of all LED.
As a kind of improvement project of the present invention, described LED unit is by three LED and connect and form, and is serially connected with control module between the LED in centre position and power supply.
Advantage of the present invention is: simple in structure, under the condition without calling signal, not every LED lights, and whole matrix display brightness is reduced, energy-conservation and prolonged display serviceable life, when calling signal was arranged, all LED all lighted, and made 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, matrix display of the present invention comprises LED unit a plurality of and that connect, each LED unit is by three LED2 and connect composition, and between the LED2 in centre position and power supply 1, be serially connected with control module 3, this control module 3 is connected with the car call system of peripheral hardware, judges whether to exist calling signal by control module 3; When not having calling signal, be in series with all not conductings of LED2 of control module 3, remaining LED2 conducting; When calling signal is arranged, the equal conducting of all LED2.
During use, matrix display 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 matrix display, it is characterized in that: described matrix display comprises LED unit a plurality of and that connect, each LED unit is by a plurality of LED and connect composition, and wherein have between a LED and the power supply and be serially connected with control module, this control module is connected with the car call system of peripheral hardware, judges whether to exist calling signal by control module; When not having calling signal, be in series with all not conductings of LED of control module, remaining LED conducting; When calling signal is arranged, the equal conducting of all LED.
