hi guys this small tut is for the newbies Types of screens TFT, TFD, OLED, LCD, STN Many people asking about the new screen TFD that appears now on the new phones specs, i search and i found this, If somebody know more about those kinds of screens, please update my information. Enjoy. TFD Thin Film Diode. A type of LCD display technology. TFD technology combines the excellent image quality and fast response times of TFT, with the low power consumption and low cost of STN. TFT Thin Film Transistor. A type of LCD display technology. Compared to other types of LCD technology, TFT features excellent image quality and response time, but uses more power, and is more expensive. OLED Organic Light-Emitting Diode. A next-generation display technology that consists of small dots of organic polymer that emit light when charged with electricity. OLED displays are thinner, lighter, brighter, cheaper to manufacture and consume less power than the current LCD displays. LCD Liquid Crystal Display. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Monochrome LCDs in phones usually have both a backlight and a reflective backing, allowing them to be equally usable in both bright light and complete darkness. Color LCDs come in many types. STN, TFT, and TFD are several common technologies used. STN Super Twisted Nematic. A type of LCD display technology. STN uses less power and is less costly than TFT technology, but at the expense of image quality and response time.
