9.1 INTRODUCTION
The cathode ray tube (CRT) has played an important role in the electronic industry ever since its birth. For more than 100 years, especially with their use as television screens, CRTs have dominated the field of displays. However, there is a strong need to develop a new kind of display technology that can help provide an innovative human-machine interface in the multimedia culture. Recently, information display devices have attracted much attention and have led to an emphasis on lighter, smaller, and, in some cases, portable devices. Conventional CRTs have many disadvantages, such as their heavy weight, large volume, and high power consumption, that preclude their use in portable applications. Many new
technologies have been recently developed for flat panel displays (FPDs), including liquid crystal displays (LCDs), plasma display panels (PDPs), and electroluminescent displays (ELDs) based on light-emitting diodes (LEDs).
