Value corresponding relation is inquired about so that the brightness value of external environmental light and the brightness value sum of fill-in light meet
The brightness value required for content shown by eye recognition electronic equipment screen.
Step 504, obtains the chromatic value of the external environmental light that chromaticity transducer gathers；
Controller obtains the chromatic value of the external environmental light that chromaticity transducer gathers.Human eye is except experiencing
Outside this characteristic of the brightness of light, it is also possible to experience tone and the saturation of the colourity of light, i.e. light, if human eye
It is simultaneously received two kinds of different light of chromatic value, then easily causes the fatigue of eyes.So it is auxiliary opening
Before helping light, chromaticity transducer needs to obtain the chromatic value of external environmental light, is real-time transmitted to controller.
Step 505, inquires about auxiliary according to the chromatic value of external environmental light in the chromatic value corresponding relation prestored
Help the chromatic value of light；
Controller inquires about auxiliary according to the chromatic value of external environmental light in the chromatic value corresponding relation prestored
The chromatic value of light.In order to avoid human eye to be simultaneously received the light of two kinds of different chromatic values as far as possible, controller is obtaining
In the chromatic value corresponding relation prestored, the colourity of fill-in light is inquired about after getting the chromatic value of external environmental light
Value so that the chromatic value of fill-in light is consistent with the chromatic value of external environmental light.
Step 506, carries the chromatic value of fill-in light and the control of the brightness value of fill-in light to luminescent device output
Signal；
Controller carries the control letter of the chromatic value of fill-in light and the brightness value of fill-in light to luminescent device output
Number, in order to luminescent device exports fill-in light to display screen, and the chromatic value of this fill-in light is taken equal in control signal
The chromatic value of the fill-in light of band；The brightness value of this fill-in light is equal to the brightness of the fill-in light carried in control signal
Value.Controller, through step 503 and step 505, has inquired the brightness value of the fill-in light of required output
And chromatic value, brightness value and chromatic value according to the fill-in light inquired are to the corresponding control of luminescent device output
Signal, in order to luminescent device exports fill-in light according to control signal.
It should be noted that controller can obtain brightness value and the chromatic value of external environmental light simultaneously, in inspection
When measuring the brightness value of external environmental light less than predetermined threshold, according to the brightness value of the external environmental light got
With brightness value and the chromatic value that chromatic value inquires about required fill-in light in corresponding corresponding relation, and then output takes
Brightness value and the control signal of chromatic value with required fill-in light, in order to luminescent device is to the screen of electronic equipment
Curtain exports corresponding fill-in light.
In sum, the control method that the embodiment of the present invention provides, collect extraneous ring by luminance sensor
The brightness value of border light, collects the chromatic value of external environmental light, in external environmental light by chromaticity transducer
Brightness value, less than in the case of predetermined threshold, inquires about fill-in light in the chromatic value corresponding relation prestored
Chromatic value, inquires about the brightness value of fill-in light in the brightness value corresponding relation prestored, so controller to
Luminescent device output carries the chromatic value of fill-in light and the control signal of the brightness value of fill-in light；Solve
Fill-in light open in the case of, due to the colourity of fill-in light and the colourity of external environmental light different and may give use
The problem of the infringement eye health that family is brought；Reach to export chromatic value consistent with the chromatic value of external environmental light
Fill-in light avoid bringing the effect of eye health problem to user.
