Detailed description of the invention
It is more fully described the exemplary embodiment of the present invention below with reference to accompanying drawings.Although accompanying drawing shows
The exemplary embodiment of the present invention, it being understood, however, that may be realized in various forms the present invention and should be by
Embodiments set forth here is limited.On the contrary, it is provided that these embodiments are able to be best understood from this
Invention, and complete for the scope of the present invention can be conveyed to those skilled in the art.
First embodiment
As in figure 2 it is shown, The embodiment provides a kind of method compensating screen color temp, the method has
Body includes:
Step 201: obtain the current color temperature parameters of screen and initial color temperature parameters.
Wherein, colour temperature is to represent the index that light source light spectrum quality is the most general.Colour temperature is to define by absolute black body
, the radiation of light source is when visual field is identical with the radiation of absolute black body, and now the temperature of black matrix just claims
Colour temperature for this light source.Wherein, the feature of low color temperature light sources is that in Energy distribution, red radiation is said some more relatively,
Commonly referred to " warm light ";After colour temperature improves, in Energy distribution, the ratio of blue radiation increases, " the coldest
Light ".Colour temperature is an important performance indexes of high-grade display, as a example by OLED display screen, along with
The increase in the service life of OLED display screen, in RGB three primary colours, the decay of blue-light-emitting thing is the fastest, green
Color takes second place, and redness is the slowest, causes display screen entirety colour temperature to reduce.That is along with mobile terminal use time
Between increase, the color temperature parameters of screen can decay, i.e. current color temperature parameters and initial colour temperature when dispatching from the factory
Parameter is different.
Step 202: according to current color temperature parameters and initial color temperature parameters, determine color temperature compensating parameter.
For ensureing that the colour temperature of screen maintains a maintenance level, can join according to current color temperature parameters and initial colour temperature
Number determines color temperature compensating parameter.Specifically, can preset color temperature compensating parameter and current color temperature parameters and
The corresponding relation of initial color temperature parameters, maps to this corresponding relation by current color temperature parameters and initial color temperature parameters
In, it may be determined that the color temperature compensating parameter needed for current screen.
Step 203: according to this color temperature compensating parameter, screen is carried out color temperature compensating.
Utilize this color temperature compensating parameter that screen is carried out color temperature compensating, it is possible to make compensate after color temperature parameters with
Initial color temperature parameters is identical, so that screen light source maintains a maintenance level all the time, so can ensure
The light filling performance of screen.
Second embodiment
First embodiment above compensates the method for screen color temp and has carried out simple introduction the present invention, below this
It will be described further by embodiment in conjunction with accompanying drawing and concrete application scenarios.
As it is shown on figure 3, the method compensating screen color temp of the present invention specifically includes following steps:
Step 301: obtain the present intensity value of each primary lights in the current color temperature parameters of screen and initial color
Initial luma values in temperature parameter.
Specifically, the process obtaining present intensity value is three primary colours in the current color temperature parameters obtaining screen respectively
The present intensity value of middle HONGGUANG, green glow and blue light.The process obtaining initial luma values is to obtain screen respectively
HONGGUANG, green glow and the initial luma values of blue light in three primary colours in initial color temperature parameters.Further, due to screen
The initial color temperature parameters of curtain is fixing, the most only need to obtain once, or can this initial color temperature parameters be made
It is that a default value reads, and without repeating to obtain this initial color temperature parameters.Owing to initial color temperature parameters is fixing
, therefore in initial color temperature parameters, the present intensity value of the HONGGUANG of three primary colours, green glow and blue light is also fixed value.
Step 302: according to current color temperature parameters and the initial color temperature parameters of each primary lights, determines corresponding primary colours
Color temperature compensating parameter.

Wait mix colours;(R), (G), (B) represent the unit quantity of red, green, blue three primary colours respectively, R, G,
B represents (R), (G), the stoichiometric amount of (B) respectively;It is to say, color F to be allotted is accomplished by using
R (R) is red, G (G) is green and B (B) blueness mixes.Assume RGB tri-base
The brightness initial value of three kinds of shiners in color is respectively as follows: Lr0、Lg0And Lb0, the light filling letter of initial setting up
The colour temperature initial value of number picture is: Xr0、Xg0And Xb0, then priming color is:
Assume Xr0=255, Xg0=255 and Xb0=255, then
After OLED display screen employs time t, the brightness decay of three kinds of shiners is arrived: Lrt、LgtAnd Lbt,
Color now is:
I.e.
Again because the coefficient of three primary colours changes the colourity in the color temperature parameters after can't affecting colour mixture in proportion,
I.e. colourity is unrelated with brightness.Therefore, for making FtWith F0Colour temperature identical, can be to signal picture during time t
Carry out color temperature compensating, it is assumed that in three primary colours, the offset of each light is respectively as follows: Xrt、XgtAnd Xbt, order
So obtain: Xrt: Xgt:Obtain further:
Specifically, can refer to below equation and be calculated current color temperature compensating parameter, wherein,

Value.By the brightness value of the white light of current three primary colours got and the colour temperature of the HONGGUANG of initial color temperature parameters
Initial value maps in this corresponding relation, can be calculated HONGGUANG color temperature compensating value.
In like manner can be calculated green glow color temperature compensating value with reference to following formula:
Wherein, X in formulagtRepresent three primary colours medium green light color temperature offset, Xg0Represent the color of green glow in three primary colours
Temperature initial value.
In like manner can be calculated blue light color temperature compensating value with reference to following formula:
Wherein, XbtRepresent blue light color temperature compensating value in three primary colours, Xb0In expression three primary colours at the beginning of the colour temperature of blue light
Initial value.
Step 303: carry out color according to the color temperature compensating parameter primary lights corresponding to screen of each primary lights respectively
Temperature compensation is repaid.
It is to say, according to the HONGGUANG color temperature compensating value in color temperature compensating parameter, the HONGGUANG of screen is carried out color
Temperature compensation is repaid;According to the green glow color temperature compensating value in color temperature compensating parameter, the green glow of screen is carried out color temperature compensating;
According to the blue light color temperature compensating value in color temperature compensating parameter, the blue light of screen is carried out color temperature compensating.
So, by current color temperature parameters and the analysis of initial color temperature parameters, obtaining color temperature compensating parameter,
Thus realize the colour temperature of the white picture of light filling of screen is compensated so that the colour temperature of supplementary lighting sources maintains one
Maintenance level, it is ensured that its light filling performance.
