The number of LCD users increased for days and days .Field Sequential Color is one kind of most attractive LCD technologies. The principle of FSC-LCD is to mix three primary colors (Red、Blue、Green) during their time of photogene in human visual system. Conventional FSC technology extracts red, blue, and green sub-frames from one image and then reconstructs a full-color image in human’s eyes.
As the FSC technology does not require color filter, it has the following advantages: (1) Reduce the cost of the panel. (2) Elevate the light transmission. (3) Reduce the power consumption. (4) Reduce the pixel space with higher resolution. (5) Good saturation of the image. Thus, for a low power and high color gamut consideration, FSC technology becomes more and more popular. However, the FSC-LCD has its disadvantage: while playing moving image, there is a CBU effect which results in motion blur.
A new multi-LC/BL algorithmic technique is proposed to eliminate the CBU effect. In forming a color image (R, G, B, and D) through the four sub-frames, the color intensity of the first three sub-frames is reduced. The fourth sub-frame can compensate the color intensity and adjust the backlight at the same time to eliminate the phenomenon of CBU. However, the fourth sub-frame should be adaptive according to the image data. Therefore, four modes, which include RGBWmin, RGBM, RGBC, and RGBY, are proposed to deal with various types of images, respectively. Besides, and a prediction approach is applied to select the best mode for the current frame. That is named Multi-LC/BL Algorithmic Technique.
