Abstract

The invention provides a screen light supplementing method, a vehicle-mounted light supplementing screen device and an automobile. The screen light supplementing method comprises the steps that a light sensor collects the change conditions of ambient light, converts the change conditions into electric signals and sends the electric signals into a processor; the processor controls and adjusts the brightness of a display screen according to the change conditions of the ambient light. The screen light supplementing method, the vehicle-mounted light supplementing screen device and the automobile have the advantages that the brightness of the display screen can be adjusted automatically according to the brightness of the ambient light around the display screen, therefore, the display screen can achieve clearer display in day time and the situation that due to the fact that the display screen is too bright at night and a driver is dazzled, the safety problem of the driver is caused is avoided.

Description

Screen light compensation method, vehicle-mounted light supplementing screen apparatus and automobile

Technical field

The present invention relates to dynamo-electric field, relate in particular to screen light compensation method, vehicle-mounted light supplementing screen apparatus and automobile.

Background technology

Display screen is very common in life, is widely used in market, public place of entertainment, factory, school, Vehicle Industry and large-scale place, has brought a lot of facilities to our life, and its research is had to practical value and good development prospect.Because display screen brightness can not change with the power of exterior ambient environment light, the reason of vehicle-carrying display screen strong illumination on daytime exists and shows that unclear or night is because of too bright and dazzling, cause driver not see the vehicle of road conditions and dealing, be easy to cause safety problem.If can realize and automatically control its brightness in different environments for use, not only make the display effect of display screen more clear but also more can avoid the dazzling safety problem causing of screen.

Summary of the invention

In order to solve the problems of the prior art, the invention provides a kind of screen light compensation method.

The invention provides a kind of screen light compensation method, comprise the steps:

Light sensor gathers the changing condition of surround lighting and is converted into electric signal and sends in processor;

Processor is according to the brightness of display screen described in the changing condition regulating and controlling of surround lighting.

As a further improvement on the present invention, processor sends control signal to switch regulating circuit, regulates the input voltage of display screen by switch regulating circuit.

As a further improvement on the present invention, described processor is single-chip microcomputer.

The present invention also provides a kind of vehicle-mounted light supplementing screen apparatus, comprise light sensor, processor, display screen, described light sensor is sent into processor for gathering the changing condition of surround lighting and being converted into electric signal, and described processor is according to the brightness of display screen described in the changing condition regulating and controlling of surround lighting.

As a further improvement on the present invention, this vehicle-mounted light supplementing screen apparatus also comprises switch regulating circuit, and described switch regulating circuit input end is connected with described processor, and described switch regulating circuit input end is connected with described display screen.

As a further improvement on the present invention, described processor is single-chip microcomputer.

The present invention also provides a kind of automobile, and this automobile is provided with described vehicle-mounted light supplementing screen apparatus.

The invention has the beneficial effects as follows: in the present invention, display screen is according to the power of surrounding environment light of living in, adjust voluntarily the brightness of display screen, shown its daytime more clear, and avoid night because of the too bright and dazzling driver's of causing of display screen safety problem.

Accompanying drawing explanation

Fig. 1 is screen light compensation method process flow diagram of the present invention.

Embodiment

As shown in Figure 1, the invention discloses a kind of screen light compensation method, comprise the steps: in step S1, light sensor gathers the changing condition of surround lighting and is converted into electric signal and sends in processor; In step S2, processor is according to the brightness of display screen described in the changing condition regulating and controlling of surround lighting.

In step S2, processor sends control signal to switch regulating circuit, regulates the input voltage of display screen by switch regulating circuit.

The invention also discloses a kind of vehicle-mounted light supplementing screen apparatus, comprise light sensor, processor, display screen, described light sensor is sent into processor for gathering the changing condition of surround lighting and being converted into electric signal, and described processor is according to the brightness of display screen described in the changing condition regulating and controlling of surround lighting.

This vehicle-mounted light supplementing screen apparatus also comprises switch regulating circuit, and described switch regulating circuit input end is connected with described processor, and described switch regulating circuit input end is connected with described display screen.

Described processor is single-chip microcomputer.

The invention also discloses a kind of automobile, this automobile is provided with described vehicle-mounted light supplementing screen apparatus.

The present invention combines with hardware circuit, reaches display screen overall brightness object relatively uniformly.The characteristic that light sensor is responded to according to the power of surround lighting of living in, the changing condition of collection surround lighting, converts thereof into electric signal and is sent in single-chip microcomputer, by single-chip microcomputer, carries out signal processing, and according to certain rule, controls the dutycycle of output PWM ripple.Between single-chip microcomputer and display screen, add a switch regulating circuit, realize the brightness adjustment of single-chip microcomputer to display screen.PWM ripple after adjusting is controlled switch regulating circuit, thereby the size of the input voltage of adjusting display screen finally realizes the brilliance control of display screen.

In the present invention, display screen, according to the power of surrounding environment light of living in, is adjusted the brightness of display screen voluntarily, is shown its daytime more clear, and avoids night because of the too bright and dazzling driver's of causing of display screen safety problem.

Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
