Color purity and range have plateaued; new technology from Nanosys promises improvements. When LCD displays took over in the computer and TV industry they brought us thinness, less power consumption, and artificially lower prices, with restricted refresh rates, viewing angle, and color spectrum. Various companies like Dolby, HP, Portrait Displays, and TruSight have built clever technologies to overcome the limitations of the basic twisted nematic (TN) crystals. The biggest breakthroughs have been the substitution of the cold cathode fluorescent lamp (CCFL) backlighting with LEDs. Quite a bit of effort has been put into backlighting LCD panels but LEDs seem to be the best choice for now.
