A cathode ray tube or CRT, is traditionally used in most computer monitors and the advent of plasma screens, LCD, DLP, OLED displays, and other technologies.As a result of CRT technology, computer monitors continue to be referred to as "The Tube". A CRT monitors works by moving an electron beam back and forth across the back of the screen.When the beam passes across the screen, the phosphors dots inside the tube are lighted up and it illuminates all the active portions that can be seen in the monitor.The lines that are drawn from top to bottom area of the screen lets the users see the images in the monitor.
An LCD monitor is thin and flat with a lot of color or monochrome pixels lined up in front of a light reflector.It uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices.
A plasma display is an emissive flat panel display where light is created by phosphors excited by a plasma discharge between two flat panels of glass.The gas discharge contains no mercury a mixture of noble gases (neon and xenon) is used instead.The said gas mixture is inert and harmless.
The glass panels seem to be vacuum sealed, because when they are broken the plasma breaks up, seemingly from the addition of air to the space.
Surface-conduction electron-emitter display (SED) is a flat-panel, high-resolution display.Some SEDs have a diagonal measurement exceeding one meter (approximately 40 inches). The SED has a lot of electron emitters and phosphors being separated by small space which all air are emptied.Each electron emitter represents one pixel.It requires lesser voltage than CRTs and requires no electron-beam.It is highly comparable to high-end CRTs when it comes to brightness and contrast.Prototype electron emitters have been developed with diameters of a few nanometers.SED technology can offer unprecedented image resolution.
Digital Light Processing (DLP) is a technology used in projectors and video projectors.DLP projectors use Digital Micromirror Device, a semiconductor chip where microscopically small mirrors are laid out to create images.Each mirror is equivalent to a single pixel.The number of mirrors corresponds to the resolution of the projected image: 800x600, 1024x768, 1280x720, and 1920x1080 (HDTV) matrices are some common DMD sizes.These mirrors reflect light through lens or a heat sink and can be repositioned speedily to reflect those lights.
The organic light emitting diode emits light emitting diode, an organic compound of OLED technology to represent picture elements on display screens.The device is cheaper to manufacture than conventional LCDs.When the emissive electroluminescent layer is polymeric, OLEDs in different quantities are deposited in rows and columns on a screen using simple "printing" methods to display graphical colors which are suitable for computer displays, portable system screens, and in advertising and information board applications.OLEDs are also used in any lighting device.OLEDs and inorganic LEDs are for distributed sources and point sources of lights respectively.
