Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
As described in background, existing have manually the GTG transition of display device and the method for adjustment of color
Adjusting, i.e. artificial rule of thumb and utilize some aids be adjusted display device, the method is the longest, typically needs
Wanting several tens minutes, the production efficiency of the display device made reduces.
Based on this, the embodiment of the present application provides a kind of GTG transition adjusting display device and the method for color, reference
Shown in Fig. 1, a kind of GTG transition adjusting display device provided for the embodiment of the present application and the flow chart of the method for color, its
In, display device include zero level GTG to m level GTG, zero level GTG to m level GTG include n debugging GTG, adjust
The method of whole i-stage debugging GTG includes:
S1: obtain presetting database, presetting database includes multiple different value and multiple difference relative luminance of arranging, often
Individual value each corresponding relative luminance is set；Obtain the target colorimetric brightness (x of i-stage debugging GTGTarget, yTarget, YTarget), black

With
(X, Y, Z) be display device can show any one colored picture time tristimulus values, (r, g b) corresponding represent
For any one luminance factor group of Red Green Blue, (x y) refers to xy in CIE1931-xyY standard colorimetric system
Value, represents colourity, and Y represents brightness.
It should be noted that tristimulus values is three kinds of light X of supposition, Y, the Z quantity of stimulus to human eye, according to poplar-Hai Mu
Three primary colors the most hereby is theoretical, the synthesis result feeling to be to be stimulated by three kinds of primitive color lights of color.It addition, the brightness of regulation X and Z is 0,
XZ line is referred to as without brightness line (alychne), only represents colourity without each point on brightness line, does not has brightness, but Y i.e. represents colourity,
Also brightness is represented.So, with X, when Y, Z calculate colourity, because Y itself represents again brightness, just make brightness calculation more convenient.I.e. exist
Colourity (x, y) under, tristimulus values (X, Y, Z) is represented by (x/y*Y, Y, ((1-x-y)/y) * Y).
Concrete, n debugging GTG is the zero level GTG of display device to the part in m level GTG, is showing
In showing device course of normal operation, display device all corresponds to red sub-pixel, green in the display effect of any one debugging GTG
The combination display effect of sub-pixels and blue subpixels, i.e. by providing corresponding GTG to believe the sub-pixel of three kinds of colors
Number, so that three sub pixels combine after showing；Further, n debugging each self-corresponding red sub-pixel of GTG, green sub-pixels and
The grayscale signal of blue subpixels, by some default operation transform means, it is possible to be transformed to zero level GTG to m level GTG
Each self-corresponding red sub-pixel, green sub-pixels and the grayscale signal of blue subpixels, and then can be by adjusting debugging ash
The grayscale signal of red sub-pixel, green sub-pixels and blue subpixels that rank are corresponding is respective target gray scale signal, to adjust
The GTG transition of whole display device and color.That is,
Debugging GTG after adjustment in the embodiment of the present application, it corresponding one should arrange value, and this value of setting should be corresponding one grey
Rank signal, the value that arranges being determined by debugging GTG corresponding red sub-pixel, green sub-pixels and blue subpixels is respective
Goal setting value after, to obtain corresponding grayscale signal, and then adjust the GTG transition of display device and color, wherein,
By adjusting debugging GTG, and then adjust the mode of all GTGs of display device, it is possible to effective reduction adjusts display device
GTG transition and the time of color, improve the efficiency adjusted.Illustrate,
If display device includes that zero level GTG, to the 16th grade of GTG, wherein, for this display device, first presets
Redness that zero level GTG is corresponding, the grayscale signal of green and blue three sub pixels are to the 16th grade of redness that GTG is corresponding, green
Relation between the grayscale signal of blue three sub pixels of normal complexion.Zero level GTG, the 6th grade of GTG, the tenth one-level are then set
GTG and the 16th grade of GTG are debugging GTG, and debug redness corresponding to GTG, the GTG of green and blue three sub pixels
Signal adjusts to respective target gray scale signal, then according to debugging GTG and zero level GTG between the 16th grade of GTG
Relation, by debugging redness corresponding to GTG, that the grayscale signal of green and blue three sub pixels is transformed to all GTGs is corresponding
The grayscale signal of red, green and blue three sub pixels, to adjust GTG transition and the color of display device.
It addition, in the production process of display device, be batch production, therefore, the display device of same model is being entered
During the adjustment of row GTG transition and color, all can use according to any one display device in the display device of this model set up pre-
If data base is adjusted.
It should be noted that for grayscale signal, it can be gray scale voltage, it is also possible to for electric current, need according to reality
The type of device judges.If during display device liquid crystal real device, grayscale signal is gray scale voltage；If real device has
During machine luminous display unit, grayscale signal corresponds to apply the electric current to light emitting diode.

Corresponding brightness.
With reference to shown in following table, corresponding for preset data database data is debugged the sub-pixel of any one color corresponding to GTG
The relation data content of value-relative luminance is set:
Table 1
Wherein, value is set for hexadecimal data, its except with relative luminance in addition to, also corresponding with grayscale signal,
Illustrate, when searching presetting database, however, it is determined that the relative luminance of the sub-pixel of m level GTG is 1, then this sub-pixel
Goal setting value is 00h, and the grayscale signal provided for this sub-pixel is corresponding preset gray scale signal, i.e. at liquid crystal indicator
In be preset gray scale voltage, and apply to the electric current of light emitting diode for presetting in organic light-emitting display device.
It should be noted that for the data content of upper table, presetting database has three sets, i.e. for red, green
With the data that blue three sub pixels all corresponding put table, and, the quantity of the debugging GTG in any one sets of data and etc.
Level is identical, but the quantity arranging value debugging GTG corresponding can be identical, it is also possible to different, is not specifically limited this；And,
For the data content of any one color sub-pixels, its value of setting needs the multiple grayscale voltages corresponding according to each debugging GTG
Being configured, i.e. under the conditions of debugging GTG, each of which arranges the most corresponding grayscale voltage of value, and correspondence is in this gray scale
Brightness under voltage；It addition, the concrete data for the representation arranging value in table 1 and relative luminance are example,
In actual application, value is set and can use hexadecimal representation, it would however also be possible to employ other expression sides such as system or numeral
Formula, is not specifically limited equally to this.For the side of the relative luminance of storage in the presetting database that the embodiment of the present application provides
Formula, compared with the mode storing simple brightness data, the mode of storage relative luminance ensure that to same model
A collection of display device is more applicable when being adjusted.
In foregoing, obtain the tristimulus values (X of black pictureBLACK, YBLACK, ZBLACK), and eliminate black picture light leak
