Claim:
1. A display device comprising a display panel, a scan driver, a data driver, and an RGB (Red, Green, Blue) data to WRGB (White, Red, Green, Blue) data conversion system, and also comprising scan lines connected to the scan driver and data lines connected to the data driver, the scan lines and the data lines being interconnected to define red sub-pixels, green sub-pixels, blue sub-pixels, and white sub-pixels that respectively and collectively constitute pixels, the RGB data to WRGB data conversion system being configured to receive input RGB values and comprising: a color enhancement assembly, which is configured to receive the input RGB values and conduct color enhancement for the input RGB values in order to obtain color-enhanced RGB values; and a four color conversion assembly, which is configured for receiving and converting the color-enhanced RGB values into output WRGB values that are fed to the data driver to be supplied from the data driver to the display panel for displaying; wherein the color enhancement assembly comprises: an HSV (Hue, Saturation, Value) conversion component, which is configured for converting the input RGB values to an HSV color space; a sine processing component, which is configured for conducting sine processing for saturation of the HSV color space; and an HSV inverse conversion component, which is configured for converting hue of the HSV color space, brightness of the HSV color space, and the sine-processed saturation of the HSV color space into the color-enhanced RGB values; and wherein the HSV conversion component is further configured to use Equation 1 to convert the input RGB values to the HSV color space, where r indicates the input R value; g indicates the input G value; b indicates the input B value; max indicates the maximum value of r, g, b; min indicates the minimum value of r, g, b; h indicates hue of the HSV color space; s indicates saturation of the HSV color space; and v indicates brightness of the HSV color space.
