Abstract
The invention relates to the field of a display screen, and specifically to an outdoor display screen brightness self adjusting method. The method comprises: a light detection module detecting environment illumination, acquiring display screen brightness, and sending acquired electric signals to a processor; the processor, according to the received electric signals of the environment illumination, calculating display screen theoretical brightness value, and storing and recording the acquired electric signals; and determining whether to adjust brightness according to the display screen brightness acquired by the light detection module and the calculated display screen theoretical brightness value. The outdoor display screen brightness self adjusting method enables a realization operation process to be simple, solves the problem of energy waste caused by uniform display after adjustment of brightness in the prior art, and improves the comfortableness of display screen watching of human eyes.
Description
Technical field
The present invention relates to display screen field, definitely, is a kind of method of outdoor display screen automatic brightness adjustment.
Background technology
Display screen has been widely used in the multiple fields such as mobile phone, computer, dull and stereotyped terminal, advertisement screen, automobile-used instrument.Along with scientific and technological progress, display screen performance has a very big improvement, but the Shortcomings that remains unchanged.The brightness regulation aspect of existing display screen is place to be improved still.
Yet traditional technology is by the linear regulation of ambient light and brightness of display screen.Out of doors, when ambient light is very strong, if simple, according to linear relationship, increase brightness of display screen, human eye can be felt very ill, also can malice cause energy dissipation; And when dawn or dusk, human eye differentiate object by day mesopic vision and noctovision concur, only according to linear relationship, regulate brightness of display screen improper especially.
Summary of the invention
A kind of method that technical matters to be solved by this invention is to provide outdoor display screen automatic brightness adjustment is intended to solve the uneven energy dissipation causing of demonstration after brightness adjusting in prior art, has promoted the comfort level that human eye is watched display screen.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of method of outdoor display screen automatic brightness adjustment, and described method comprises:
Step 1: light detection module testing environment illuminance and collection brightness of display screen, send to processor by the electric signal of collection;
Step 2: described processor calculates the theoretical brightness value of display screen according to the electric signal of the ambient light receiving, and the electric signal of stored record collection;
Step 3: the theoretical brightness value of the brightness of display screen value gathering according to light detection module and the display screen of calculating, judges whether to want brightness adjusting.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the theoretical brightness of the brightness of display screen gathering according to light detection module in described step 3 and the display screen of calculating, judges whether to want brightness adjusting, and details are as follows:
If brightness of display screen value is greater than the display screen theoretical value of calculating, enter into energy saver mode, automatically regulate the brightness that reduces display screen;
If brightness of display screen value equals the display screen theoretical value of calculating, enter into usual mode of operation;
If brightness of display screen value is less than the display screen theoretical value of calculating, enters into usual mode of operation and automatically regulate the brightness that increases display screen.
Further, described smooth detection module adopts TCS3200 sensor, and it is STC12C5630 single-chip microcomputer that described processor adopts.
The invention has the beneficial effects as follows: the method for outdoor display screen automatic brightness adjustment of the present invention, realize operating process simple, solve in prior art and after brightness adjusting, show and the uneven energy dissipation causing promoted the comfort level that human eye is watched display screen.
Accompanying drawing explanation
Fig. 1 is the realization flow figure of outdoor display screen automatic brightness adjustment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, be the realization flow figure of outdoor display screen automatic brightness adjustment of the present invention, details are as follows:
Figure step 1: light detection module testing environment illuminance and collection brightness of display screen, send to processor by the electric signal of collection;
Step 2: described processor calculates the theoretical brightness value of display screen according to the electric signal of the ambient light receiving, and the electric signal of stored record collection;
Step 3: the theoretical brightness value of the brightness of display screen value gathering according to light detection module and the display screen of calculating, judges whether to want brightness adjusting;
The theoretical brightness of the brightness of display screen gathering according to light detection module in described step 3 and the display screen of calculating, judges whether to want brightness adjusting, and details are as follows:

If brightness of display screen value equals the display screen theoretical value of calculating, enter into usual mode of operation;
If brightness of display screen value is less than the display screen theoretical value of calculating, enters into usual mode of operation and automatically regulate the brightness that increases display screen.
Described smooth detection module adopts TCS3200 sensor, and it is STC12C5630 single-chip microcomputer that described processor adopts.
In this example, the TCS3200 sensor that light detection module adopts Liang Pian U.S. TAOS company to produce, described sensor can be converted into frequency signal by the colouring information that collects surround lighting by programming.Sensor internal can be integrated configurable silicon photo diode array and electric current be converted into the converter of frequency, the frequency of output is the square wave being directly proportional to light intensity, can be by controlling the light intensity of ruddiness, blue light and green glow output.
This single-chip microcomputer comprises the signal that receives light detection module, sends control signal, carries out computing and judgement, and storage operation result etc., are assigned to respectively PCA module by carrier cycle numerical value.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
