what is a monitor
It is the most commonly used display device. The monitor, utilizes a cathode ray tube (CRT). CRT monitors generally produce images by the raster-scan method. In this method, an electron beam varying in intensity, is moved back and forth horizontally across the face of the monitor. As the beam is directed to each spot on the phosphor-coated screen, it illuminates the spot in proportion to the voltage applied to the beam. Each spot represents a picture element or pixel. When the electron beam has scanned the entire screen and illuminated each pixel, one can see a complete image. The image that can be seen is the one traced on the retinas of eyes by the light beam. However, this image will fade unless it is refreshed. Thus, the electron beam must scan the screen very rapidly (a minimum of 60 times per second), so that the intensity of the image remains approximately the same and the screen does not appear to flicker.
The screen resolution of a particular monitor is determined by the number of pixels that make up the screen. Monitors are currently available with 64,000 to more than 2 million pixels per screen. The greater the resolution of a monitor the greater the storage demand on the computer. This is because the image must be stored in memory before it can be displayed. Two techniques used to store computer images are: bit-mapped and character-addressable.
In a bit-mapped display, each pixel is uniquely addressable. Information must be stored for each pixel on the screen. This technique needs quite a large computer memory and provides the most detailed display. For graphical applications, such as CAD/CAM, this detail is essential. However, for applications such as word processing, a characteraddressable display is appropriate. In a character addressable display, the screen is divided into character positions. Only the characters to be displayed are stored in memory. As each character is retrieved from memory, it is converted into a pattern of dots or pixels by a special character generator module.
Monochrome or colour: Some monitors display images in only one colour while others are capable of producing images in colours. Monochrome monitors use a single electron beam and display one colour, generally green, amber, or white, on a black background. The phosphor composition of the screen determines the colour. Colour monitors produce multi-colour images by combining the red, blue, and green colours in varying intensities. Each pixel is made up of three colour dots: red, blue, and green. It will appear to glow in different colours depending on the intensity of each individual dot in the pixel. Colour monitors are commonly referred to as RGB monitors since they employ three election beams, one for each colour. Colour monitors are categorized as CGA, EGA, VGA and SVGA depending on the resolution. CGA monitors provide the least resolution (approximately 300 × 200 Pixels) and SVGA monitors provide the greatest resolution (1000 × 800 pixels and greater).
Monitor interface: A monitor requires an appropriate interface to communicate with a computer. For example, a colour graphics interface board is needed for a colour monitor. This interface will generally not work with a monochrome monitor and might even damage it. Dozens of monitor interface boards are available for use with microcomputers. A caution must be exercised to match the interface to both the monitor and the computer.
Using a television: Some smaller microcomputer systems can be used with a standard television. The basic difference between a monitor and a television set is that the resolution of a television is substantially less than that with a monitor. Also the television requires the use of a modulator to interface the computer output with the television. The modulator combines the separate audio and visual signals sent by the microcomputer into a single modulated signal as required by a television. Most inexpensive computer systems designed for use with a television set generally have a built-in modulator.
Flat-Panel Displays
For laptop computers more compact, low-power, durable monitors are used. A number of flat-panel display technologies are available for this. The most common are the plasma and liquid crystal displays.
Plasma displays: A plasma display consists of an ionized neon or argon gas (plasma) sealed between two glass plates. One plate encases a set of fine horizontal wires and the other a set of vertical wires. Pixels are formed by the intersections of the horizontal and vertical wires. A single pixel can be turned on by sending a current through its horizontal and vertical wires. This causes the gas between the wires to produce an amber glow. The images produced by plasma displays are generally very clear, and not subject to the flicker. Plasma displays are generally more expensive than the CRT displays.
Liquid crystal displays:
Liquid crystal displays (LCDs) have been used for several years in calculators and digital watches. A thin layer of a liquid crystal substance is suspended between two thin sheets of polarized glass and separated by a wire grid into tiny squares. As current is applied to the wires the liquid crystal substance within the square changes from clear to opaque or black. The thousands of clear and black squares produce patterns of characters.
The disadvantage of LCD displays is lack of brightness and resolution as compared to CRT and plasma displays. The quality of the LCD display depends on the surrounding light and the viewing angle. It is sharpest and clearest when viewed in brightness from the front.
