Claim:
1. An image data processing method, characterized in that the method comprises the following steps: (A) using a display comprising a processor and a memory comprising a plurality of program instructions executable by the processor to receive a first image data, wherein the first image data comprises a first red sub-pixel image data, a first green sub-pixel image data, and a first blue sub-pixel image data; (B) using the processor to execute the plurality of program instructions to execute a gamma correction process for the first red sub-pixel image data, the first green sub-pixel image data, and the first blue sub-pixel image data to obtain a second red sub-pixel image data, a second green sub-pixel image data, and a second blue sub-pixel image data; (C) using the processor to execute the plurality of program instructions to generate a first white sub-pixel image data according to the second red sub-pixel image data, the second green sub-pixel image data, and the second blue sub-pixel image data; (D) using the processor to execute the plurality of program instructions to generate a third red sub-pixel image data, a third green sub-pixel image data, and a third blue sub-pixel image data according to the second red sub-pixel image data, the second green sub-pixel image data, the second blue sub-pixel image data, and the first white sub-pixel image data; and (E) using the processor to execute the plurality of program instructions to execute an inverse gamma conversion process for the third red sub-pixel image data, the third green sub-pixel image data, the third blue sub-pixel image data, and the first white sub-pixel image data to obtain a fourth red sub-pixel image data, a fourth green sub-pixel image data, a fourth blue sub-pixel image data, and a second white sub-pixel image data; the grayscale value corresponding to the first white sub-pixel image data=2 times a preset variable to the fifth power−4 times the preset variable to the fourth power+the preset variable to the third power+the preset variable to the second power+the preset variable, wherein the value of the preset variable is smaller than a predetermined value; or the grayscale value corresponding to the first white sub-pixel image data=−2 times a preset variable to the fifth power+9 times the preset variable to the fourth power−14 times the preset variable to the third power+8 times the preset variable to the second power, wherein the value of the preset variable is greater than or equal to the predetermined value.
