Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
The core concept of the present invention is: according to daylight saving time information and current time dot information, calculate current ambient brightness, then in conjunction with multi-point average brightness and computed current environment brightness, calculate and obtain backlight control parameter, carry out backlight control with the display to terminal.
First the process calculating current ambient brightness according to daylight saving time information and current time dot information is described below.Specific as follows:
To be divided into several periods every day, each period is correspondingly arranged ambient brightness value E.This variable E is for substituting REGmax according to the change of ambient brightness, and REGmax is a fixed value originally, the register parameters value that namely ambient brightness is corresponding.Along with the change of ambient brightness, and variable E is used to substitute this REGmax.Between ambient brightness and variable E can according to the demand of user, for proportional relation or inverse relation.The present embodiment is preferably proportional relation.The ambient brightness value E that the concrete period is corresponding, can be as shown in table 1 below:
Table 1. period and ambient brightness value corresponding to period
| Period | Light state | Ambient brightness value E |
| Sunrise-morning | The low light level | E1 |
| Morning-afternoon | High light | E2 |

| Morning | 9:00 | 9:00 | 9:00 |
| In the afternoon | 16:00 | 16:00 | 16:00 |
| Sunset | 20:00 | 19:00 | 18:00 |
For shown in the ambient brightness value table 3 specific as follows that the set time of above-mentioned sunrise, afternoon, afternoon, sunset, period and period are corresponding:
| Period | Ambient brightness value E |
| 6:00≤t<9:00 | E1 |
| 9:00≤t<16:00 | E2 |
| 16:00≤t<18:00 | E3 |
| Sunset-sunrise | E4 |
Based on the mapping relations of the period information of upper table 3 and ambient brightness value E, after obtaining current time point, first judge the period belonging to current point in time, then obtain ambient brightness value corresponding to this period, as current ambient brightness value.
