It, can be according to N number of ash after the brightness of the white picture of each grayscale under rank and the brightness of the blue picture under each grayscale
The brightness of the white picture of each grayscale under rank and the brightness of the blue picture under each grayscale are from the bright of white picture
Degree --- the ratio that R/B and G/B are found in R/B, G/B ratio look-up table calculates then according to the brightness of blue picture
The brightness of red picture corresponding with the brightness of blue picture and the brightness of green picture.
106, the corresponding brightness-voltage look-up table of the brightness of the white picture under each grayscale is determined.
In the present embodiment, it can determine that the brightness of the white picture under each grayscale is corresponding bright as follows
Degree-voltage look-up table:
Step 1: the brightness of each sprite under the current gray of testing standard screen, the brightness packet of each sprite
It includes: the brightness of white picture, the brightness of red picture, the green brightness of picture and the brightness of blue picture；
Step 2: by the driving (integrated circuit of the brightness input standard screen of each sprite
(integratedcircuit, IC) with the corresponding brightness-voltage look-up table of the brightness for generating white picture, wherein inside IC
It is stored with the conversion formula of brightness and voltage in register, i.e., brightness is inputted into driving IC, it can know that the brightness is corresponding
Voltage value；
Step 1 is repeated to step 2, until generating the corresponding brightness-electricity of brightness of the white picture under each grayscale
Press look-up table.

Brightness-the voltage look-up table in color Huang face can show the form such as following table:
It should be noted that above table numerical value therein is only exemplary and fills in, do not represent to white picture brightness
Corresponding R, G, the restriction of B brightness-voltage look-up table, can also be other numerical value, in addition above be in table form
It is illustrated, can also be other display formats, as long as can show that the brightness of the white picture under each grayscale is corresponding red
The brightness of picture, the green brightness of picture and brightness-voltage look-up table of blue picture, specifically without limitation.Its
In, for the brightness not indicated in table, can be calculated by the value linear interpolation at the brightness both ends.
It should be noted that do not limit step 106 herein executes sequence, it is only necessary to be executed before step 107.
107, according to the brightness of blue picture, the brightness of red picture and the brightness of green picture under each grayscale
The corresponding voltage value of brightness of each sprite is found out in the corresponding brightness-voltage look-up table of the brightness of white picture.
In the present embodiment, it is determined that the brightness of the blue picture of each grayscale under N number of grayscale, the brightness of red picture with
And the brightness of green picture, and specify the brightness corresponding R of the white picture of each grayscale under N number of grayscale, G, B brightness-
Voltage look-up table, it can according to the brightness of the blue picture of each grayscale under each grayscale of N, the brightness of red picture and green
The brightness of color picture is found from R, G, B brightness-voltage look-up table, the blue picture of each grayscale under N number of grayscale it is bright
The voltage of corresponding blue picture is spent, the electricity of the corresponding red picture of the brightness of the red picture of each grayscale under N number of grayscale
The voltage of the corresponding green picture of the brightness of the green picture of pressure and each grayscale under each grayscale of N.
108, the driving IC that the corresponding voltage value of the brightness of each sprite inputs screen to be adjusted is detected, and treated
The screen for not meeting target requirement in screen is adjusted to be corrected, so that the screen after correction meets the target requirement.
In the present embodiment, can by the voltage of the blue picture of each grayscale under N number of grayscale obtained in step 107,
The voltage of the voltage of red picture and green picture, the driving IC for inputting screen to be adjusted are detected, and are treated and adjusted in screen
The screen for not meeting target requirement is corrected, so that the screen after correction meets target requirement.I.e., it is possible to will belong to same
The driving IC of the voltage input of the sprite of a grayscale screen to be adjusted verifies display effect, and the color that will not meet user demand
Coordinate and the screen of gamma demand are corrected, such as can be by the method for single point correction, i.e., to being unsatisfactory for user demand
Chromaticity coordinates and gamma demand screen R, G, B voltage is finely adjusted, thus the relatively target of voltage at this time
Value, by R, G, B voltage is slightly adjusted the chromaticity coordinates and gamma demand that can meet user demand up and down.
In view of the foregoing it is apparent that formulating two tables of comparisons in advance, one is that the corresponding ratio of brightness of white picture is looked into
Corresponding brightness-the voltage look-up table of the brightness of table and white picture is looked for, blue picture is then calculated according to user demand
Brightness, it is corresponding by the brightness for finding out blue picture from the ratio look-up table and brightness-voltage look-up table defined
The corresponding voltage of brightness of voltage, the corresponding voltage of brightness of green picture and red picture, and each monochrome that will be found out
The driving IC of the voltage input of picture screen to be adjusted is detected, and carries out school to detected the screen for not meeting user's requirement
Just, the problems such as volume production uses can be taken a long time in the prior art and is not suitable for effective solution.
The embodiment of the present invention is retouched from the angle of the method for the chromaticity coordinates and brightness that automatically correct display screen above
