1. CRT Monitor – cathode ray tube (CRT) is an evacuated glass envelope containing an electron gun (a source of electrons) and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons. When electrons strike the fluorescent screen, light is emitted. The electron beam is deflected and modulated in a way which causes it to display an image on the screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), echoes of aircraft detected by radar, etc. CRT screens have much deeper cabinets compared to LCD screens for a given area. They can, however, display higher resolutions on a smaller screen. Also, LCDs have worse color rendition due to the fluorescent lights used as backlights, even though they can be brighter overall. The result is that CRTs are useful for displaying photos with high pixels per unit area and correct color balance, and for having large desktop area concentrated into a small screen. Having 1600 × 1200 resolution in 18 inch 4:3 rather than 20–24 inch on most LCDs also allows less eye movement to view different parts of the screen. In addition to offering high-resolutions in a smaller screen area, they offer the resolutions more cheaply for a given resolution. In general, rear-projection displays and LCDs require less power per display area, but plasma displays consume as much as or more than CRTs. However, CRTs still find adherents in computer gaming because of higher resolution per initial cost and small response time. CRTs are often used in psychological research that requires precise recording of reaction times. CRTs are also still popular in the printing and broadcasting industries as well as in the professional video, photography, and graphics fields due to their greater color fidelity and contrast, better resolution when displaying moving images, and better view from angles, although improvements in LCD technology increasingly alleviate these concerns.
2. LCD Monitor – A thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin film transistor (TFT) technology to improve image quality. TFT LCD is one type of active matrix LCD, though it is usually synonymous with LCD. It is used in televisions, flat panel displays and projectors. Being slim and compact is one of the advantages of a LCD monitor. However, it is much expensive as compared to CRT.
