Computer monitor
A computer generates display data to be displayed on the monitor. Desktop computers include a monitor which is usually supported by a desk surface or the desktop computer housing. Notebook computers comprise a base and a monitor pivotally connected to the base with a pivoting connector. A cathode ray tube (CRT) displays a picture by displaying a plurality of pixels on a screen using electric charges which are discharged from a cathode ray tube and impact a fluorescent plate. The cathode ray tube, in general, has a long history as a display device. Initially available as a monochrome display, and later available to display colors using separate controls for red, green and blue, the CRT had been the main display device of choice for computer monitors. However, CRT monitors are large and bulky due to the large vacuum tubes that enclose the cathode and extend from the cathode to the faceplate of the display. Additionally, CRTs require a relatively high voltage power supply to sufficiently accelerate electron beams for displaying images. Because of the drawbacks associated with a conventional CRT monitors, other types of display technologies have been developed in the past to form high quality thin displays. The flat panel display (FPD) has gradually replaced the traditional cathode ray tube (CRT) display. The flat panel display (FPD) may include a liquid crystal display (LCD), a plasma display panel (PDP), an organic light emitting display (OLED), and a field emission display (FED), etc. In particular, flat panel LCD displays are widely used in computer industry.
