[0010] However, please refer to Image 6 As shown, the white balance processing makes blue corresponding to the turning point C' of the curve L6' 6 with turning point C' 5 , C' 4 Deviations occur, resulting in this gray scale interval I. The display screen viewed by the user at the angle of side view (the angle of 60 degrees relative to the front view) appears yellowish, which is commonly known as the yellowish spot (yellowish), which in turn leads to a decrease in image quality.

[0156] Please refer to Figure 14 As shown, it shows the liquid crystal display panel 3 of the second embodiment of the present invention. The liquid crystal display panel 3 receives a plurality of pixel data D30, any pixel data D30 has at least one first color sub-pixel data D31. The LCD panel 3 includes a driving unit 31 and a pixel array 32 .

[0157] The driving unit 31 generates a first data driving signal S311 and a second data driving signal S312 according to a first color sub-pixel data D31.

[0158] The pixel array 32 has a plurality of pixels P30, any pixel P30 has at least a first color sub-pixel P31, and any first color sub-pixel P31 has a first region P311 and a second region P312. Wherein the first area P311 and the second area P312 respectively display a first color sub-pixel correction data according to the first data driving signal S311 and the second data driving signal S312. In other words, since the first region P311 and the second region P312 respective...
