[0009] However, please refer to Figure 6, the processing of white balance 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.
