New ELQD displays will in fact work a bit like OLED screens in that they won’t require a backlight of any kind but they’ll create a further advantage due to their superior color palette creation ability –to a degree even higher than that achievable by OLED. At the same time, because each QD subpixel inside such screens will be capable of individual activation/deactivation, ELQD screens will deliver the same perfect blacks, pixel-perfect local dimming and wide viewing angles as those achieved by OLED screens today. Another benefit of such pixel luminance efficiency would be lower overall power consumption, since relatively inefficient, broadly luminous LED backlights can (literally) be removed from the picture.
