With the increasing popularity of mobile phone color screen, the material of mobile phone screen is becoming more and more important. The color screen of mobile phone is different because of LCD quality and research and development technology. There are TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors you can display, the more complex images you can display, and the more layers you can have.
