Grade.
It in an implementation, can be in the corresponding relationship of display pattern, backlight power involved in step 202 and brightness degree
There are the first brightness degree, which can be maximum brightness grade corresponding to the first display pattern.It can be appreciated that
First display pattern is only to enable the display pattern of the corresponding sub- display unit of white channel, and the second display pattern is while enabling
The display pattern of the corresponding sub- display unit of white channel and the corresponding sub- display unit of multiple primary color channels, so in phase
Under same backlight intensity, since the sub- display unit of multiple primary color channels is in the open state, a certain amount of light can be also penetrated,
Then the light transmission capacity of the second display pattern is significantly greater than the first display pattern.Therefore, brightness degree corresponding to the second display pattern
It is all larger than the corresponding brightness degree of the first display pattern, that is, is greater than the first brightness degree.And in the present solution, in view of son display is single
Under member is in running order, it will consume certain power, then under certain screen intensity demand, multiple primary color channels are closed in selection
Corresponding sub- display unit, power consumption will more be saved by only enabling the corresponding sub- display unit of white channel, it is subsequent will to this into
Row illustrates.
Optionally, in corresponding relationship, corresponding first backlight power of the first brightness degree is equal to the divided by default ratio
Lowest backlight power subtracts the difference of the backlight power of the adjacent brightness grade under the second display pattern under two display patterns.
Wherein, the first backlight power is determined by the operating power and default ratio of every a sub- display unit；Default ratio is
The ratio of the light transmission capacity of the corresponding sub- display unit of white channel in the light transmission capacity of each display unit and each display unit.
In an implementation, terminal can first determine white channel pair in the light transmission capacity and each display unit of each display unit
The ratio (i.e. default ratio) of the light transmission capacity for the sub- display unit answered.Specifically, including multiple in the display panel that terminal includes
The corresponding display unit of pixel, each display unit include the corresponding sub- display unit of white channel and three chrominance channel of red, green, blue
Corresponding sub- display unit.The colored filter of corresponding color, each colored filter are provided in every sub- display unit
The color of mating plate is different, and transmittancy is also corresponding different, it can is indicated by light transmittance.Herein, it is tested based on a large amount of,
Light transmittance (the light transmission of alternatively referred to as sub- display unit of the colored filter in different sub- display units can substantially be estimated
Rate), it specifically can be as follows：The light transmittance of Red lightscreening plate R is about 15%, and the light transmittance of green color filter G is about 50%, blue
The light transmittance of optical filter B is about 10%, and the light transmittance of white filter W is about 95%.It should be noted that above-mentioned light transmittance is equal
Belong to for example, not being defined to this programme.In this way, can be based on the saturating of the corresponding sub- display unit of each color channel
The display area of light rate and the corresponding sub- display unit of each color channel, determines the light transmittance of a display unit, tool
Body, it is assumed that the display area of the corresponding sub- display unit of white channel accounts for the display area 1/3, Jin Eryi of a display unit
The light transmittance of a display unit can be：2/3*1/3* (15%+50%+10%)+1/3*95%=0.16+0.32=0.48=
48%.And if only opening the corresponding sub- display unit of white channel, light transmission capacity can be 1/3*95%=0.32=
32%, so default ratio can be 48%:32%=3:2.Certainly, numerical value involved in the above process can take any reasonable
Value, the light transmittance of such as multiple primary color channels are respectively x1, x2, xn, and the light transmittance of white channel is y, and each primary colours are logical
The corresponding display area accounting in road is a, and the accounting of the corresponding display area of white channel is 1-na, so, presetting ratio M can be with
For
Later, the first brightness degree can be determined according to the operating power and above-mentioned default ratio of every a sub- display unit
Corresponding first backlight power.Specifically, the overall operating efficiency of the corresponding sub- display unit of multiple primary color channels can be W, the
One backlight power is A, when screen is in the first brightness degree, when being shown according to the first display pattern, and corresponding first back
Optical power A, and if corresponding backlight power B, A and B should meet A-B≤W when being shown according to the second display pattern, this
Sample, when being switched to the first display pattern, the brightness degree in order to guarantee screen is constant, needs to increase the backlight power of terminal, and
From the point of view of energy conservation, the backlight power of increase should be less than the work that a primary color channels are saved more under the first display pattern
When power, enabling the first display pattern can be more energy saving, so the first backlight power A should at least meet following relational expression：A/
(A-W)=M, i.e. A=MW/ (M-1).Herein, based on above-mentioned example, it is assumed that the chief engineer of the sub- display unit of multiple primary color channels
Make efficiency W=100mw, M 3:2, then A=300mw.It is noted that the corresponding sub- display unit of each primary color channels
Operating power may include power consumed by the corresponding driving circuit of every sub- display unit, gate circuit and digital circuit.
Further, corresponding first backlight power of the first brightness degree is equal to the second display pattern divided by default ratio
Lower lowest backlight power subtracts the difference namely the second display pattern of the backlight power of the adjacent brightness grade under the second display pattern
It is lower lowest backlight power B, backlight power △ b of adjacent brightness grade under the second display pattern, the first backlight power A, default
Ratio M meets following relationship：A/M=B- Δ b.Continue based on above-mentioned example, available B- △ b is equal to 200mw, changes an angle
From the point of view of degree, namely if realizing the first brightness degree using the second display pattern, backlight power should be set as 200mw.
Optionally, in corresponding relationship, the difference of the corresponding backlight power of adjacent brightness grade and under the first display pattern
The ratio of the difference of the backlight power of adjacent brightness grade under two display patterns is equal to default ratio.
In an implementation, it is based on above-mentioned calculating, the brightness change in order to guarantee each brightness degree screen is more uniform, then may be used
According to above-mentioned default ratio, to determine that the difference of the corresponding backlight power of adjacent brightness grade and second is shown under the first display pattern
Show the relationship of the difference of the backlight power of the adjacent brightness grade under mode.That is adjacent brightness grade is corresponding under the first display pattern
The ratio △ a/ △ b of the difference △ b of the backlight power of adjacent brightness grade under the difference △ a and the second display pattern of backlight power
Equal to default ratio M.Based on above-mentioned example, then △ a/ △ b=M=3:2.Further, technical staff can be according to backlight function
The upper limit value and total brightness grade of rate, determine △ a and △ b, for example, the backlight power upper limit is 400mw, brightness degree 10
Grade, then △ a=60mw and △ b=40mw specifically can be with reference table 1：
Table 1
Step 203, it is based on target display pattern and target backlight power, display output is carried out to gray level image.
In an implementation, terminal is in the corresponding target display pattern of object brightness grade and the target back for determining user setting
After optical power, current display mode can be adjusted to target display pattern, while backlight power is adjusted to target backlight function
Then rate carries out display output to gray level image.It should be noted that in adjustment process, since display pattern is become
Change, then in order to which the color for guaranteeing image is undistorted, then before display, it is also necessary to the image data of image be converted, then
It is shown again based on the image data after conversion.
In the embodiment of the present invention, when showing gray level image, if user has adjusted the brightness degree of screen, terminal can
With according to the brightness degree of user setting, in the corresponding relationship of the brightness degree of preset display pattern, backlight power and screen
In, it determines corresponding display pattern and backlight power, may then based on the display pattern and backlight power determined, to ash
Degree image carries out display output.In this way, due to increasing the corresponding sub- display of the higher white channel of light transmittance in display unit
Unit, so when needing certain screen intensity, the demand of backlight intensity is lower, to show the electricity that backlight is lost when image
It can be less.
Another embodiment of the present invention also discloses a kind of display panel, for realizing the method for above-mentioned display image, content
It can be as follows：
Display panel includes the display unit of multiple pixels, and each display unit includes the corresponding sub- display list of white channel
The corresponding sub- display unit of first and multiple primary color channels, wherein as shown in figure 3, the corresponding sub- display unit of multiple primary color channels
Display area it is equal, the display area of the corresponding sub- display unit of white channel is greater than the corresponding sub- display of each primary color channels
The display area of unit.
