Abstract:
1. A 4-primary color display comprising: a display panel including a plurality of 4-primary color pixels, each of the plurality of 4-primary color pixels including a red (R) liquid crystal cell for a red display, a green (G) liquid crystal cell for a green display, a blue (B) liquid crystal cell for a blue display, and a white (W) liquid crystal cell for a white display; and a pixel data rendering circuit configured to produce 4-primary color pixel data corresponding to a second horizontal resolution, which is equal to a physical horizontal resolution of the display panel, using 3-primary color pixel data corresponding to a first horizontal resolution, which is two times higher than the physical horizontal resolution of the display panel, determine a weighting factor based on a luminance ratio of two 3-primary color pixel data so as to increase a cognitive horizontal resolution of a luminance with respect to the 4-primary color pixel data to the first horizontal resolution, and reflect the weighting factor to the calculation of a gray value of one 4-primary color pixel data.
