Abstract

We demonstrate a wide color gamut and high brightness LCD TV using a conventional cold cathode fluorescent lamp (CCFL) backlight with five-primary (red, green, blue, yellow, and cyan) colors. Without changing the CCFL backlight and pixel size, the color gamut is widened from $\sim$72% to $\sim$90% and meanwhile the white brightness is increased by more than 20%, as compared to the three-primary. We also validate our simulation results using a 32$^{\prime\prime}$ five-primary multi-domain vertical alignment LCD TV prototype. The agreement is reasonably good.
