Value.
The third aspect, provides a kind of user terminal, and user terminal includes: one or more processors, memory, bus
System and one or more programs, processor are connected with memory by bus system；Wherein, one or more programs are deposited
In memory, which includes instruction for storage, and instruction makes user terminal execution the when being executed by user terminal
The method of one side.
In embodiments of the present invention, user terminal can determine that (i.e. the grayscale value of sub-pixel point is equal target pixel points
Pixel), and judge whether the grayscale value of the sub-pixel point of target pixel points is greater than the first preset value.If target pixel points
The grayscale value of sub-pixel point is greater than the first preset value, then the target pixel points are the pixel of white, which may
For background.Therefore, it is preset by the way that the grayscale value of the sub-pixel point of target pixel points is set smaller than the second of the first preset value
Value can reduce the grayscale value of background, and the display content that will not have not only watched in this way user influences too much, but also can delay to show
Shield the rate of decay of the organic material of (such as OLED display screen or other display screens), and the grayscale value by reducing background can also be kept away
It is dazzling to exempt from background.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is described.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a kind of grayscale setting method and user terminals, for delaying the organic of OLED display screen
The rate of decay of material.
It should be understood that the grayscale setting method of the embodiment of the present invention can be applied to user terminal.The user terminal may include but
It is not limited to mobile phone (such as Android phone, iOS mobile phone), tablet computer, mobile internet device (Mobile Internet
Devices, abbreviation MID), the mobile terminals such as personal digital assistant (Personal Digital Assistant, abbreviation PDA)
(Terminal)。
Referring to Figure 1, Fig. 1 is a kind of flow diagram of grayscale setting method provided in an embodiment of the present invention.Such as Fig. 1 institute
Show, which may include 101~103 parts.Wherein:
101, user terminal determines target pixel points.
So-called grayscale, be by it is most bright with it is most dark between brightness change, several pieces are divided into, in order to carry out signal input
Corresponding screen intensity control.Every digitized video be all as combined by many points made of, these point be also known as pixel
(pixels), usually each pixel can show many different colors, it is by red (R), green (G), blue (B) three sons
Pixel composition.Wherein, red sub-pixel point is for being displayed in red and (glowing), and green sub-pixels point is for showing green (hair
Green light), blue subpixels point is for being displayed in blue (blue light-emitting).The light source of each sub-pixel, behind can be shown
Different gray scales.And grayscale is represented by most secretly to the stratum level of different brightness most bright.This intermediate level is more,
The picture effect that can be presented is also finer and smoother.By taking 8bit panel as an example, 28 powers can be showed, are equal to 256 brightness
Level, we are just referred to as 256 grayscale.Each pixel on display screen, is combined by the red, green, blue of different luminance levels,
Ultimately form different color points.That is, on screen each pixel color change, be all by constituting this in fact
Brought by the gray scale variation of three RGB sub-pixels of point.
In the embodiment of the present invention, which is exactly in display screen (such as OLED display screen or other display screens), red
The all equal pixel of the grayscale value of sub-pixels point, green sub-pixels point and blue subpixels point.For example, including picture in display screen
Vegetarian refreshments 1, pixel 2, pixel 3, pixel 4, pixel 5 and pixel 6, the grayscale value of the red sub-pixel point of pixel 1
Equal to the grayscale value of green sub-pixels point, the grayscale value of green sub-pixels point is equal to the grayscale value of blue subpixels point, then pixel
Point 1 is target pixel points, other pixels are similarly.
102, user terminal judges whether the grayscale value of the sub-pixel point of target pixel points is greater than the first preset value.
In the embodiment of the present invention, if user terminal judges that the grayscale value of the sub-pixel point of target pixel points is greater than first and presets
Value, then execute 103 parts.Optionally, if user terminal judges that the grayscale value of the sub-pixel point of target pixel points is pre- less than first
If value, then terminate this process.
For example, the grayscale value of the sub-pixel point of target pixel points is 255, then user terminal judges whether 255 be greater than the
One preset value.
103, the grayscale value of the sub-pixel point of target pixel points is set the second preset value by user terminal.
In the embodiment of the present invention, second preset value is less than the first preset value.For example, the red sub-pixel of target pixel points
The grayscale value of point, green sub-pixels point and blue subpixels point is 255, and the first preset value is 200, then user terminal is by target
The grayscale value of the red sub-pixel point of pixel, green sub-pixels point and blue subpixels point is disposed as 199, and (or other are less than
200 value).The grayscale value of the red sub-pixel point of target pixel points, green sub-pixels point and blue subpixels point is respectively provided with
After 199, red sub-pixel point, green sub-pixels point and blue subpixels point just pass through grayscale value progress color and show.
In existing practical application, when pixel is that the grayscale value of sub-pixel point is equal, what target pixel points were shown
Color is grey.When the grayscale value of group pixel is 255, the color of display is pure white, the grayscale value of group pixel
When being 0, the color of display is ater.White is carried out content as background and shown by usual user terminal, and white
Grayscale value is higher, and the organic material consumption of the higher display screen of grayscale value is bigger, therefore white background can be to organic material of display screen
Material causes biggish consumption, and the higher white background of grayscale value also can be dazzling.By implementing method described in Fig. 1, user
Terminal can determine target pixel points (i.e. the pixel that the grayscale value of sub-pixel point is equal), and judge the son of target pixel points
Whether the grayscale value of pixel is greater than the first preset value.If it is default that the grayscale value of the sub-pixel point of target pixel points is greater than first
Value, then the target pixel points are the pixel of white, which may be background.Therefore, by by target pixel points
The grayscale value of sub-pixel point be set smaller than the second preset value of the first preset value, the grayscale value of background can be reduced, so both
The display content that will not be watched user influences too much, and can delay display screen (such as OLED display screen or other display screens)
Organic material the rate of decay, and by reduce background grayscale value also can avoid background it is dazzling.
