Display methods is used in terminal, comprises the following steps.
In step 201, whether the luminance difference between terminal monitoring display screen and current environment is more than the second present count
Value, if it is, step 202 is performed, if not, continuing to monitor.
Wherein, terminal is the equipment with display screen, e.g., smart mobile phone, tablet personal computer, TV, game machine etc., this reality
Apply example and specific limit is not made to the type of terminal.Current environment refers generally to the environment residing for terminal, if user is closed in light
The indoor using terminal closed, then current environment is indoor environment；If user's night is in outdoor application mobile phone, current environment
Outdoor environment.Current environment can be the dark environment of brightness or the dark environment of brightness, and the present embodiment is to work as front ring
Border is to illustrate exemplified by the dark environment of brightness.
When whether luminance difference of the terminal between monitoring display screen and current environment is more than the second default value, can first it obtain
Take the brightness value that display screen is current, and obtain the brightness value of current environment, and by the brightness value of the display screen got with
The brightness value of current environment is compared, and according to comparative result, determines whether is luminance difference between display screen and current environment

Road, indigo plant (B) Color Channel.R, each Color Channel of G, B is divided into 255 rank brightness values, and 0 rank brightness is most dark, and 255 rank brightness are most
It is bright.When the brightness value of tri- Color Channels of R, G, B is identical, gray color is shown as, the gray color can be white, black or ash
Color, specifically, if the brightness value of tri- Color Channels of R, G, B is 0 rank, black is shown as, if tri- colors of R, G, B
When the brightness value of passage is 255 rank, white is shown as；When the brightness value difference of tri- Color Channels of R, G, B, coloured silk is shown as
Color.
In step 204, for any pixel point, terminal judges any two face in three Color Channels of the pixel
Whether the luminance difference between chrominance channel is more than the first default value, if it is, step 205 is performed, if it is not, then performing step

The color effect of the background colours such as book, the present embodiment, which provides method, can be directed to each pixel, using different brightness adjustment approach
Brightness to each pixel is adjusted.
Before being adjusted using brightness of the different brightness adjustment approach to each pixel, terminal is needed according to each
The brightness value of three Color Channels of pixel carries out brightness judgement to each pixel, so as to according to judging that brightness results are
Each pixel chooses corresponding regulative mode.Any pixel point being directed on display screen, when specifically judging, terminal needs
First obtain the luminance difference between any two Color Channel in three Color Channels of the pixel, and then the luminance difference that will be obtained
Compared with the first default value, according to comparative result, any two color in three Color Channels of the pixel is judged
Whether the luminance difference between passage is more than the first default value.Wherein, when the first default value is that pixel shows as colour, three
The minimum value of luminance difference in individual Color Channel between any two Color Channel, first default value can be 8cd/m2、
10cd/m2、16cd/m2Deng the present embodiment not specific restriction of size work to the first default value.
It should be noted that for any pixel point, any two in three Color Channels for calculating the pixel
During brightness value between individual Color Channel, three luminance differences are can obtain, in three Color Channels for judge the pixel arbitrarily
When whether the luminance difference between two Color Channels is more than the first default value, and if only if, and three luminance differences are simultaneously greater than first
During default value, step 205 is performed；When any one in three luminance differences is less than the first default value, step 206 is performed.
In step 205, terminal is adjusted using the first preset algorithm to the brightness value of each Color Channel of pixel
Section, obtain the brightness value after pixel regulation.
When the luminance difference between any two Color Channel in three Color Channels for judge the pixel is more than first
During default value, illustrate that the color that the pixel is showed is colored and three Color Channels of the pixel brightness value difference
It is larger, the brightness value of each Color Channel of the pixel can be now adjusted using the first preset algorithm.
When it is implemented, terminal can use the first preset algorithm, the brightness value of each Color Channel of pixel is reduced
Identical multiple, obtain the brightness regulation value of each Color Channel, and then the brightness regulation value based on each Color Channel, pass through by
The brightness regulation value of three Color Channels is overlapped, and obtains the brightness value after pixel regulation.Wherein, the first preset algorithm is such as
Shown in following formula (1)：
Yi=Xi/n (1)；
Wherein, YiFor the brightness regulation value of each Color Channel, XiFor the brightness value of each Color Channel, i=1,2,3, Y1
For the brightness regulation value of beauty chrominance channel, X1For the brightness value of beauty chrominance channel, Y2For the brightness regulation value of green color passage, X2
For the brightness value of green color passage, Y3For the brightness regulation value of blue Color Channel, X3For the brightness value of blue Color Channel, n is diminution
Multiple.Certainly, the first preset algorithm can also have other forms, and the present embodiment no longer illustrates one by one.

The brightness value X of the beauty chrominance channel of vegetarian refreshments1For 160cd/m2, green color passage brightness value X2For 240cd/m2, blue Color Channel
Brightness value X3For 120cd/m2, the multiple of diminution is 4 times, then using the formula in above-mentioned (1), can obtain：
Y1=X1/ n=160/4=40cd/m2；
Y2=X2/ n=240/4=60cd/m2；
Y3=X3/ n=120/4=30cd/m2；
By by the brightness regulation value of beauty chrominance channel obtained above, the brightness regulation value of green color passage and blue face
The brightness regulation value of chrominance channel is overlapped, and can obtain the brightness value after pixel regulation.
In step 206, terminal is adjusted using the second preset algorithm to the brightness value of each Color Channel of pixel
Section, obtain the brightness value after pixel regulation.
When the luminance difference between any two Color Channel in three Color Channels for judge the pixel is less than first
During default value, illustrate that the brightness value difference of three Color Channels of the pixel is smaller, can now use the second preset algorithm
The brightness value of each Color Channel of the pixel is adjusted.
When it is implemented, terminal can use the second preset algorithm, by the brightness regulation value of each Color Channel of pixel
Given luminance scope is adjusted, obtains the brightness regulation value of each Color Channel, and then the brightness based on each Color Channel is adjusted
Section value, by the way that the brightness regulation value of three Color Channels is overlapped, obtain the brightness value after pixel regulation.Wherein, refer to
It is terminal brightness range according to determined by the brightness value of current environment to determine brightness range, and the given luminance may range from 0cd/
m2~32cd/m2、40cd/m2~60cd/m2Deng.Shown in for example following formula (2) of second preset algorithm：
Yi=a+Xi/255*(b-a) (2)；
Wherein, YiFor the brightness regulation value of each Color Channel, XiFor the brightness value of each Color Channel, i=1,2,3, Y1
For the brightness regulation value of beauty chrominance channel, X1For the brightness value of beauty chrominance channel, Y2For the brightness regulation value of green color passage, X2
For the brightness value of green color passage, Y3For the brightness regulation value of blue Color Channel, X3For the brightness value of blue Color Channel, a is specified
The minimum value of brightness range, b are the maximum of given luminance scope.Certainly, the second preset algorithm can also have other forms, this
Embodiment no longer illustrates one by one.
It is adjusted by using the first preset algorithm, the brightness value after pixel regulation can be obtained.If for example, picture
The brightness value X of the beauty chrominance channel of vegetarian refreshments1For 233cd/m2, green color passage brightness value X2For 235cd/m2, blue Color Channel
Brightness value X3For 230cd/m2, given luminance may range from 0cd/m2~32cd/m2, i.e. a=0cd/m2, b=32cd/m2,
The formula in above-mentioned (2) is then used, can obtain：
Y1=a+Xi/ 255* (b-a)=0+233* (32-0)/255=29.2；
Y2=a+X2/ 255* (b-a)=0+235* (32-0)/255=29.5；
Y3=a+X3/ 255* (b-a)=0+230* (32-0)/255=28.9；
By by the brightness regulation value of beauty chrominance channel obtained above, the brightness regulation value of green color passage and blue face
The brightness regulation value of chrominance channel is overlapped, and can obtain the brightness value after pixel regulation.
In step 207, when all pixels point is through overregulating, terminal carries out screen based on the brightness value after regulation and shown

After all pixels on display screen are adjusted using above-mentioned brightness method for turning down sound, terminal root
Brightness value after being adjusted according to each pixel, you can carry out screen display.Now the background colour on screen not only will not distortion, and
And screen intensity will not also damage to the eyes of user.
So far, realized by above-mentioned steps 201 to 207 under the dark environment of brightness, to the tune of terminal display
Dark operation.On this basis, if the brightness of the environment residing for terminal becomes strong suddenly, e.g., user opens the light of interior, this
When excessively dark display screen the eyesight of user can also be damaged, therefore, the method that the present embodiment provides is detecting display
When luminance difference between screen and current environment is more than the second default value, execution is lightened to the operation of display screen.
During specific execution, terminal will generate a brightness regulation instruction, and brightness regulation instruction can be used for showing terminal
Display screen curtain lightens, and afterwards, under the triggering of brightness regulation instruction, terminal can obtain three of each pixel on display screen
The brightness value of Color Channel.Any pixel point being directed on display screen, if it is determined that in three Color Channels of pixel
Luminance difference between any two Color Channel is more than the first default value, and terminal can use the 3rd preset algorithm to the pixel
