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.
