Abstract :
Color gamut and color shifts of the film-compensated multi-domain in-plane-switching (IPS) and multi-domain vertical alignment (MVA) liquid crystal displays (LCDs) are calculated quantitatively using light-emitting diodes (LEDs) and cold-cathode fluorescent lamp (CCFL) backlight. Simulation results indicate that the LED backlight exhibits better angular color uniformity and smaller color shifts than CCFL. In addition, the color gamut can be further widened and the color shift reduced when using color-sequential RGB-LED backlight without color filters. In general, both IPS and MVA LCDs show relatively small color shift under different backlights, but MVA has a lower color shift using the optimized uniaxial compensation films
