We introduce a novel type of Adobe RGB liquid crystal display (LCD) monitor with pixels composed of red (R), green (G), and blue (B) sub pixels, combined with a typical blue LED chip based white LED backlight. The key is to apply a newly developed deep green colorant to green sub pixel when the transmittance decrease of the LCD panels was minimized for product design. As a result, the new technology makes it possible to reproduce the Adobe RGB coverage of 99.9% as well as to realize slim LCD.

Multi-primary color (MPC) technology is generally used to increase color gamut [1][2]. But, in this paper, MPC technology was used to enhance luminance better than conventional Liquid Crystal Displays (LCD) with 3 color RGB sub-pixel. We have proposed 4 Primary Color System that has additional yellow(Y) color with an asymmetric sub-pixel structure. The asymmetric sub-pixel RGBY structure LCD has 18% higher luminance efficiency than conventional RGB LCDs under the same power consumption. This paper shows the improved luminance by multiprimary color technology (RGBY). P
