Cathode-ray tube (CRT) displays had been the predominant display technology for purposes such as home television screens and computer monitors. Compared with previous display technologies, CRTs have advantages in terms of superior color resolution, high contrast and brightness, wide viewing angles, fast response times, and low manufacturing costs. However, CRTs also have major drawbacks such as excessive bulk and weight, high power consumption, fragility, strong electromagnetic emissions, the need for implosion and x-ray protection, undesirable analog device characteristics, and a requirement for an unsupported low internal pressure envelope that limits screen size. With the development of an information oriented society, the demands on display devices have increased. To address the inherent drawbacks of CRTs, different flat display devices have been developed for use in various devices, such as the liquid crystal display device (LCD), the plasma display panel (PDP), the electroluminescent display (ELD), and the vacuum fluorescent display (VFD). The flat panel display device may be classified into two types depending on whether it emits or receives light. One type is light-emitting display devices that emit light to display images and the other type is a light-receiving type display device that uses an external light source to display images. Plasma display panels, field emission display devices and electroluminescence display devices are light-emitting type display devices and liquid crystal displays are light-receiving type display device. Liquid crystal display devices are widely used as displays of portable information terminals because of their thinness and lightness and also because of their small electric power consumption. The general structure of an LCD consists of a liquid crystal layer that is positioned between pair of panels including field generating electrodes and polarizers. The liquid crystal layer is subject to an electric field generated by the electrodes and variations in the field strength change the molecular orientation of the liquid crystal layer. Among many kinds of FPD devices, the electroluminescence display (also known as ELD, using organic light emitting diodes) device makes use of electroluminescence phenomenon in which light is generated when an electric field of certain intensity is applied to a fluorescent substance. Organic electroluminescent displays are expected as alternatives to the currently prevailing liquid crystal displays because the organic electroluminescent display has a small size and is light weight, also has low power consumption, high brightness, and short response time,  as compared to a liquid crystal display device. The organic electroluminescent display device can display every color in a range of a visible light and has a high brightness and a low operating voltage. Various types of touch screen displays have been developed to facilitate user interaction with graphical user interfaces (GUIs).  Touch screens are gaining popularity for numerous applications, including electronic catalogs, in-store locators, corporate training, point-of-information kiosks, vending, and amusement, multimedia marketing, banking and financial transactions, ticket sales, multimedia demos, interactive education, and museum displays. A touch screen generally employs one of four types of touch technologies: capacitive, resistive, infrared, and surface acoustic wave.
