25.1: Invited Paper: Development of Wide-Color-Gamut Mobile Displays with Four-Primary-Color LCDs

We developed a multiple color LCD with pixels composed of red (R), blue (B), yellowish green (YG) and emerald green (EG) sub pixels, combined with a white LED backlight. The color gamut was extended to 105% of the NTSC standard. Also the 3‐ to 4‐primary‐color conversion algorithm using the three‐dim...

Description
Summary:We developed a multiple color LCD with pixels composed of red (R), blue (B), yellowish green (YG) and emerald green (EG) sub pixels, combined with a white LED backlight. The color gamut was extended to 105% of the NTSC standard. Also the 3‐ to 4‐primary‐color conversion algorithm using the three‐dimensional look‐up‐table (LUT) is described with the color reproduction characteristics for driver‐integrated circuits on mobile LCDs.
