A saturation adjustment method is disclosed for compensating over-saturation adjustment. The saturation adjustment method includes: adjusting a first full-scale saturation corresponding to a hue of a color wheel to become a second full-scale saturation wherein the second full-scale saturation is greater than the first full-scale saturation; setting a critical saturation corresponding to the hue based on the first and second full-scale saturations; and adjusting a first saturation within a range between the critical and second full-scale saturations corresponding to the hue to become a second saturation based on the first full-scale, second full-scale and critical saturations. Furthermore, disclosed is a color adjustment system essentially including a saturation adjuster for adjusting the first saturation greater than the critical full-scale saturation to become the second saturation based on an adjusted full-scale saturation and the critical saturation.

A pixel structure includes a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel. The red sub-pixel, the green sub-pixel and the blue sub-pixel are suitable for providing a first white light, and a chroma coordinate of the first white light is (x1, y1). The white sub-pixel is suitable for providing a second white light, and a chroma coordinate of the second white light is (x2, y2). The chroma coordinate of the first white light is different from the chroma coordinate of the second white light, that is, (x1, y1)≠(x2, y2), while x2≧x1 and y2≦y1.

A multi-primary color display has a backlight source and pixels. Each pixel has at least four sub pixels, which display red primary color, green primary color, blue primary color and a fourth primary color, respectively. At the peak position of the fourth primary color located in the wavelength range between 550 nm˜600 nm, the relative luminance ratio of the fourth primary color to the green primary color is greater than or equal to 0.5. When the ratio of the relative luminance meets the requirement and the relative luminance of a newly added primary color is greater than a certain value, the colors beyond the three-primary color gamut, which includes natural colors and other colors outside the natural color gamut, can be reproduced.

In an exemplary RGBW display apparatus, a plurality of four-color image output signals and a plurality of mapping scale ratios are generated according to a plurality of three-color image input signals. Furthermore, a backlight output intensity outputted from a backlight module is dynamically adjusted according to the mapping scale ratios and a white color signal adjust ratio is generated. In addition, a white color signal in each of the four-color image output signals is adjusted to be an updated white color signal according to the white color signal adjust ratio.

A display device includes a number of sub-pixels. A main region and a sub region are defined in each sub-pixel, and correspond to a first pixel electrode and a second pixel electrode respectively. The first and the second pixel electrodes are separated from each other and thereby forming a gap between the first and the second pixel electrodes substantially perpendicular to the gate lines. Each sub-pixel includes a coupling electrode, a first switching transistor, a second switching transistor and a sharing transistor. The coupling electrode is capacitively coupled with the first pixel electrode. The first switching transistor and the second switching transistor are electrically connected to a gate line, a data line, and respectively connected to the first and the second pixel electrodes. The sharing transistor is electrically connected to another gate line, the coupling electrode and the second pixel electrode.
