In the present embodiment, determine that the corresponding target thang-kng rate of current environment brightness can specifically use step 202 ~ step
203 operation.
The desired display brightness namely display need to adjust to target display brightness, it refers to bright in current environment
Under degree, at least disclosure satisfy that user normally watches the display brightness of its display content demand, such as extraneous environmental light brightness compared with
, it is necessary to improve the display brightness of display when strong, user can normally watch the display content of display, external environment light
When degree is weaker, then display there is relatively low display brightness can meet user normally watch demand.
The desired display brightness can be correspondingly arranged for varying environment brightness in advance, obtain current environment brightness
Afterwards, directly search；Can also be the corresponding relation formula for being previously provided with desired display brightness and ambient brightness, then basis is worked as
Preceding ambient brightness, can calculate desired display brightness.
Because the display brightness of display is relevant with thang-kng rate and back light source brightness, back light source brightness is can to detect to obtain
Know, therefore the desired display brightness according to display and current display brightness, it may be determined that go out target thang-kng rate.
Wherein, the display brightness of display has following brightness relationship formula：
The display brightness of display=back light source brightness *（Input the grey exponent number of GTG/input）gamma；
From the foregoing, the display brightness of display is relevant with back light source brightness, gamma and input GTG.And input
GTG is relevant with the display color of display, and the adjustment of input GTG needs not influence it to show color.The grey exponent number of input refers to
The quantity of GTG is inputted, for example, there are tri- GTGs of R, G, B, then quantity is three, what general value was to determine.Gamma represents display
A kind of non-linear relation of display brightness and back light source brightness, it is a kind of parameter for influenceing display to show, bright in display
During degree display, generally with curve, i.e., gamma form is present.Therefore, thang-kng rate described in the present embodiment is a kind of may

Therefore according to desired display brightness, it may be determined that go out target thang-kng rate.
For example, when thang-kng rate is gamma, back light source brightness, input GTG are constant, then, can according to desired display brightness
To determine corresponding target gamma.
When thang-kng rate is the relation value of gamma and back light source brightness, according to the desired display device brightness of display, in input
When GTG is constant, according to the above-mentioned relation value that can be corresponded to and draw target thang-kng rate for target gamma and back light source brightness.
When thang-kng rate is gamma and input GTG relation value, according to the desired display device brightness of display, in backlight
When brightness is constant, according to the above-mentioned relation value that can be corresponded to and draw target thang-kng rate for target gamma and input GTG.
Step 204：According to the target thang-kng rate, the display value target display brightness is adjusted.
