Color performance of a MVA LCD using LED backlight

The color performances such as color gamut, color shift, and gamma curve of a MVA LCD using LED backlight are calculated quantitatively. Simulation results indicate that LED backlight exhibits better angular color uniformity and smaller color shifts than CCFL backlight. Color gamut can be further widened and color shift reduced when using color-sequential RGB-LED backlight without color filters. In the meantime, the angular-dependent gamma curves are less influenced using different backlights. The obtained quantitative results are useful for optimizing the color performances and color management of high-end LCD monitors and LCD TVs.
