Method and system for adjusting white balance, method for making liquid crystal display

A method for adjusting white-balance, comprising the steps of:

• S1, entering a value of white-balance of a standard sample into a display panel;
• S2, controlling the display panel to display a test image having different grayscale value so as to attain a full grayscale value of the display panel;
• S3, determining whether the attained full grayscale value is within a specification, if yes, then proceeding into next step, and if no, then proceeding into step S4;
• and
• S4, recalculating the white-balance value based on a difference between the attained full grayscale value and the white-balance value of the standard sample, and reentering the calculated white-balance value into display panel, and returning to step S2;
• wherein step S2 comprises the following sub-steps:
• S21, controlling the test image of the display panel;
• S22, collecting brightness and colorfulness of the test image when it is displayed onto the display panel;
• S23, converting the brightness and colorfulness under different grayscale into white field chromaticity and gamma value under different grayscale;
• and
• S24, simulating a variation curve based on the white field chromaticity coordinate and gamma value according to the attained white field chromaticity and gamma value under tested grayscale, and attaining the white field chromaticity and gamma value of the display panel under full grayscale.
