To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under the premise of creative work, shall fall within the protection scope of the present invention.
The exemplary embodiment of the present invention provides a kind of screen adjustment method, as shown in Figure 1, including the following steps：
S1：Obtain white chromaticity coordinates of the reference area of screen on predetermined viewing point；

White chromaticity coordinates；Then bending region is divided into several subregions according to bending degree, obtains the colors on subregion respectively
The chromaticity coordinates of sub-pixel；Pass through the assorted sub-pixel luminance values of adjusting subregion again；The brightness value of each sub-pixels is in conjunction with known to
The chromaticity coordinates of each sub-pixels be able to adjust white chromaticity coordinates of the subregion on predetermined viewing point.I.e. by adjusting subregion
Assorted pixel brightness value, reach in conjunction with the chromaticity coordinates of each sub-pixels of subregion and adjust subregion on predetermined viewing point
The purpose of white chromaticity coordinates so that white chromaticity coordinates of the subregion on predetermined viewing point with reference area in predetermined viewing point
On the difference of white chromaticity coordinates fall within preset range, to weaken or eliminate colour cast problem.
The difference of the white chromaticity coordinates for the reference area watched on predetermined viewing point and the white chromaticity coordinates in bending region
Value is fallen within preset range, refers to the white of the white chromaticity coordinates and bending region of the reference area seen on predetermined viewing point
Chromaticity coordinates is identical or close enough.When the white chromaticity coordinates of the two is identical, two regions are seen on predetermined viewing point
White displays picture is consistent, and deviation is not present；When the white chromaticity coordinates of the two is close enough, in predetermined viewing with seeing on you
The deviation of white displays picture in two regions be not easy to be recognized by the human eye, i.e., deviation is smaller.As long as reference area and curved
The difference of white chromaticity coordinates of the folding area domain on predetermined viewing point is fallen within preset range, and two regions show other colors
When, see that the picture of display can not also have deviation or with smaller deviation on predetermined viewing point.Reference area and curved
The preset range of the difference of the white chromaticity coordinates in folding area domain can test acquisition or theoretical acquisition according to those skilled in the art,
Such as both white chromaticity coordinates difference (Wx ', Wy ') within (20,20), or (10,10), (5,5), (2,2) with
It is interior.
It should be noted that reference area can be an area of a fixed plane domain or on-fixed bending

Wy2) being equal to known to (Wx1, Wy1) can survey, and (Rx2, Ry2), (Gx2, Gy2) and (Bx2, By2) is it is also known that can survey, with reference to above-mentioned public affairs
Formula can obtain brightness value RL2, GL2 and BL2 that subregion should have on predetermined viewing point.
In S4, by adjusting brightness value of the subregion colors sub-pixel on predetermined viewing point, in conjunction with known constant
Chromaticity coordinates of each sub-pixels of subregion on predetermined viewing point is sat to adjust white color of the subregion on predetermined viewing point
Mark.Wherein, corresponding assorted in driving circuit that can be by adjusting subregion in order to adjust the brightness of subregion colors sub-pixel
The driving current of sub-pixel.Certainly, each sub-pixels can also be corresponded in the driving circuit by adjusting subregion as deformation
Driving voltage adjust the brightness of subregion colors sub-pixel.
Specifically, driving circuit is that TFT driving circuits flow through the current value of each sub-pixel in TFT driving circuits
For：
As it can be seen that flow through the current value of each sub-pixel and the capacitance of storage capacitance is proportionate, therefore can be by adjusting every
The capacitance of storage capacitance reaches adjusting sub-district to adjust the driving current in each pixel in the TFT driving circuits of one sub-pixel
The purpose of the brightness value of each sub-pixels in domain, it is final so that each sub-pixels of subregion are in the predetermined brightness value watched on point
RL2, GL2 and BL2.
