Abstract

The advantage of RGB color sequential displays is that they have no color filters, but the disadvantage is that they need to run at high refresh rates (≫180 Hz) to prevent flicker and color breakup. At Philips we have developed an alternative color sequential display, which can operate at relatively low refresh rates (∼100 Hz) without disturbing color breakup or flicker. The display has two color filters per pixel (cyan and magenta) on the LCD panel and the backlight can generate two types of spectra (blue-green and green-red), which results in a wide gamut four primary display effectively. One part of the paper describes the color reproduction, including color filter design, gamut mapping and multi-primary conversion. The other part deals with the reduced perception of color breakup on the novel spectrum sequential display compared to conventional color sequential displays. A working prototype of the display has been build for demonstration purposes.
