Fig. 4 is that the present invention adjusts the gamma correction curve figure being adopted during led brightness.
Specific embodiment
In order that measure, creation characteristic, reached purpose and effect that the technology of the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
The present invention comprises as follows:
Led display screen 1；
Led display screen control system 2, connects led display screen 1, is provided with led automatic brightness adjustment module 3 in it；
Light sensor module 4, is evenly distributed in the surrounding of led display screen 1, is shown with led including multiple light sensors
Screen control system 2 connects.
The brightness value that led automatic brightness adjustment module 3 real-time tracking light sensor module 4 is collected, thus change
The brightness of led display screen 1.
Led automatic brightness adjustment module 3 includes: light data sink 31, quantized data equalizer 32, data storage
33rd, gamma (gamma) corrector 34.
With reference to the gamma curve explanation shown in led automatic brightness adjustment modular structure block diagram as shown in Figure 3 and Fig. 4
How the present invention automatically adjusts the brightness of led display screen 1 according to the brightness value that light sensor module 4 is collected:
The brightness value each collecting is fed back by way of bus communication or point-to-point communication by multiple light sensor modules 4
To light data sink 31；
Because multiple light sensor modules are arranged on the diverse location of led screen body, each light sensor module collects
Ambient brightness value is different, and it is equal that light data sink carries out brightness value different brightness collection values in quantized data equalizer
One change；
Quantized data equalizer carries out corresponding brightness after uniforming brightness value by way of look-up table in data storage
The lookup of data, finds corresponding brightness data；
This brightness data is sent to gamma corrector and carries out Data correction, realize automatically adjusting of led brightness of display screen.
The gamma correction curve of gamma corrector is as shown in figure 4, automatic brightness adjustment arranges two threshold values: minima
