Abstract:
A white balance method of a four-color pixel system is disclosed. The method includes the following steps: lightening a plurality of sub pixel units according to two different combinations respectively so as to display a white color; and regulating a gray-scale value of each sub pixel unit, and taking the gray-scale values of each of the sub pixel units, which enable the white color displayed by two different combinations to meet respective preset conditions as output four color gray-scale values. The display effect of the four-color pixel system can be improved through the method, which is simple, efficient, and easy to perform.

Claim (Index 8):
The method according to  claim 7 , wherein the gray-scale value of each sub pixel unit is regulated according to formulas as follows: { L v \ue8a0 ( W i ) = Y \ue8a0 ( R o ) + Y \ue8a0 ( G o ) + Y \ue8a0 ( B 0 ) + Y \ue8a0 ( M i ) x i = ( X \ue8a0 ( R o ) + X \ue8a0 ( G o ) + X \ue8a0 ( B o ) ) / S y i = ( Y \ue8a0 ( R o ) + Y \ue8a0 ( G o ) + Y \ue8a0 ( B o ) ) / S M i = f \ue8a0 ( R i , G i , B i ) M o = f \ue8a0 ( R o , G o , B o ) , \n \ue89e and \ue89e \n \ue89e { L v \ue8a0 ( W i ) / L v \ue8a0 ( W 255 ) = ( i / 255 ) 2.2 S = X \ue8a0 ( R o ) + Y \ue8a0 ( R o ) + Z \ue8a0 ( R o ) + X \ue8a0 ( G o ) + Y \ue8a0 ( G o ) + Z \ue8a0 ( G o ) + X \ue89e ( B o ) + Y \ue8a0 ( B o ) + Z \ue8a0 ( B o ) wherein L v (W i ) represents a brightness of a white color with a gray-scale value being i; x i , y i  represent chromaticity coordinates of the white color; R i ,G i ,B i ,M i  represent four color gray-scale values obtained through an input three color gray-scale value after conversion according to the three-color to four-color calculation algorithm; R o ,G o ,B o ,M o  represent output four color gray-scale values; X( ),Y( ),Z( ) represent tri-stimulus values of each sub pixel unit; and f represents a mapping relationship from the gray-scale values of the red sub pixel unit, the green sub pixel unit, and the blue sub pixel unit to the gray-scale value of the fourth sub pixel unit which is in accordance with the three-color to four-color calculation algorithm.
