Light filling, preceding light are closed, which can be the bright of the ability to bear for being suitble to oneself eye of user oneself setting
Degree is also possible to count the brightness of the suitable reading obtained according to big data analysis, for example, studies have found that, 100nit is most
It is suitble to the brightness read, then 100nit can be set by first predetermined luminance.
If the ambient brightness information around the total reflection screen is less than the first predetermined luminance, but it is pre- to be more than or equal to second
If when brightness, illustrate the environment light of current reflective be not enough to provide enough brightness for user read etc., but current environment into
Row light filling can't also cause excessive injury to the eyes of user, and therefore, light compensates total reflection screen before opening.It should
Second predetermined luminance can be the brightness that user is arranged according to the ability to bear oneself of the eyes of oneself, be also possible to according to big
The brightness of the ambient enviroment for the unsuitable carry out light filling that data analysis statistical obtains.
When user does not turn on light or shields electronic product using total reflection under lamp excessively dark surrounds, system thinks
Environment is excessively dark in the case of this, the pupil of user can be allowed to dissipate after light filling naturally big, block eye fluids circulation, it is easy to
Lead to glaucoma, and the blue content of screen at this time is also excessively high, the injury caused by the eyes of user is larger.
If ambient brightness information around the total reflection screen is less than the ring of the second predetermined luminance, that is, Current ambient
The brightness in border is excessively dark, if bigger injury can be caused to user instead by carrying out light filling, and it is not recommended that user in such feelings

But enter after dormant state, current ambient brightness information, which is obtained, every third preset duration is judged,
Once detecting that ambient brightness changes, and new ambient brightness information is more than or equal to the second predetermined luminance, that is, reaches fair
When the lowest term that family allowable is shielded using total reflection, breaking dormancy state opens total reflection screen, and issues unlatching prompt information,
It can carry out voice prompting or light prompt etc..
Eyes have the ability of certain self-recovery, but force the number used excessively to will lead to eyes and also come not
And self-recovery is just again by injury, it is therefore necessary to limit the number for forcing to use in certain time.
There is following two mode to be judged, when a kind of every the 4th preset duration counting user operation information indicate into
Row forces the pressure number that uses, if it is larger than or equal to preset times, then after the 5th preset duration in forbid entering it is strong
System uses, and issues and prompt information is forbidden to inform user.Another kind is that every user enters pressure using once then counting user is grasped
Making information indicates the pressure number for carrying out forcing to use, if the maximum time span that the pressure in preset times uses is greater than
Equal to the 4th preset duration, then after the 5th preset duration in be prohibited from entering pressure use, and issue forbid prompt information to accuse
Know user.
