S3. according to the standard two, current color temperature mode and the corresponding backlight illumination adjusted value of low blue light grade are calculated, and Backlight illumination is adjusted according to the backlight illumination adjusted value.
Further, keep artificial light brighter if user needs, it is whiter, in the step S2, further includes:
If low blue light grade is set to off in custom menu, it sets color temperature value to the default colour temperature of the color temperature mode Value.
It further, is save the cost, the eyeshield mode regulating method of the display device further include:
Light sensation characteristic is formulated, obtains environment bright angle value in real time;
According to the light sensation characteristic, the corresponding backlight illumination adjusted value of current environment light is calculated;
It is worth corresponding backlight illumination adjusted value and current color temperature mode and low blue light grade pair according to current environmental light brightness The backlight illumination adjusted value answered, calculates the adjusted value of practical backlight illumination, and adjusts backlight illumination with this.
Specifically, to promote the accuracy that backlight is adjusted, the real-time acquisition environment bright angle value includes:
Acquisition environment bright angle value in real time;
Carry out original intensity calculating, the enhancing of black scene and the processing of dynamic backlight grade;
Ambient compensation adjustment is carried out according to the light sensation grade being arranged in custom menu, obtains environment bright angle value.
For the accuracy for further promoting backlight adjusting, the real-time acquisition ambient brightness value further include:
It is continuous to obtain environment bright angle value ten times in real time, the average value of the environment bright angle value of ten acquisitions is calculated, according to The average value adjusts backlight illumination.
For the accuracy for further promoting backlight adjusting, the eyeshield mode regulating method of the display device further include:
The environment bright angle value that the average value of the real-time environment bright angle value and last time obtain;
If the variation of the average value of the environment bright angle value is more than preset range, the brightness of the environment light is updated Value;
According to updated environment bright angle value, the corresponding backlight illumination adjusted value of current environmental light brightness is calculated.
Specifically, to avoid display device from frequently adjusting backlight illumination, the preset range is 10%.
The present invention also provides a kind of display devices, carry out eyeshield using the eyeshield mode regulating method of such as above-mentioned display device Mode tuning.
The beneficial effects of the present invention are: the eyeshield mode regulating method of display device of the present invention, by difference Drop blue light processing, effectively control blue laser output are done according to different low blue light classification standards under color temperature mode, and passes through current colour temperature Mode and corresponding blue light grade adjust backlight illumination accordingly, coordinate current colour temperature more, and picture shows softer, avoid out The case where now comparing light by force, improves the anti-fatigue ability of human eye, reduces injury of the display device to human eye.
