Managers chip is lower than in other types, but the quality is undoubtedly higher.

SSTN display - a color super-twist nematic (color display based on technology of twisted liquid crystals), LCD technology is based on a passive matrix (TFT - aktivnomatrichnaya), less expensive to produce, but with more than TFT response time. Modern CSTN displays have a response time of 100 ms and a viewing angle of 140 degrees, it is worse than that of TFT, but with higher contrast and half the price of TFT.

OLED displays or Organic Light Emitting Diodes (electroluminescent displays based on organic light-emitting semiconductors). If the previous displays were needed additional illuminated elements, here are lit LEDs themselves. They in turn much higher quality TFT-screens. They have a wide viewing angle, high contrast, excellent color reproduction. But mass production of OLED displays, still can not.
