Genoa Color`s ( http://www.genoacolor.com ) Multi-primary color (MPC) technology is used to achieve wide gamut color reproduction. In this paper, MPC technology is applied to liquid crystal display (LCD). 4-primary color and 5-primary color displays were created, with the percentage of NTSC and brightness better than conventional LCDs. Furthermore, the cost of MPC display is cheaper than the display with wide gamut LED backlight.
Introduction
Conventional image systems display images based on three primary colors (RGB). However, not all of the colors perceived by the human eyes can be
obtained by mixing three primary colors. Therefore, MPC displays are essential if vivid color reproduction is to be achieved. The displays use more than three primaries to display a color, and provide a wide color gamut.
Recently, the studies of MPC display were introduced. The 4-primary color display was developed by Epson1. This display reproduces a gamut more than 100% of the NTSC gamut by using red, blue, yellowish green, and emerald green color filters. The application of MPC technology in projector was discussed by Genoa2, 3, 4. There are several types of wide gamut demonstrators that include 4, 5 and 6 primaries. The research of 6-primary color LCD was published by Samsung5 and Mitsubishi6.
In this paper, the MPC panels are created, and three types of MPC displays are compared. Besides, the panel design, color conversion algorithm, and the performance of MPC panel are described.
