Staging is the main product of a computer. The two main types of displays in use are liquid crystal displays (LCDs), known as flat screens. Cathode ray tubes (CRTs), an older technology. Everyone has advantages and disadvantages.

Older displays now use the cathode ray tube technology, it developed for televisions. The cathode is a charged electrode that emits an electron beam. A charged electrode (referred to as an anode). A cathode ray tube is a vacuum tube that has one or more electron guns. (cathodes) One end that emits a stream of electrons on the screen at the other end. It covers the interior of the screen.

A lattice of phosphorescent materials called phosphors. When the phosphors hit by electrons, they illuminate. Matches organized in groups of three called pixels. Each pixel has a point that emits one of three basic colors: red, green, and blue. The magnetic coil in the tube controls gives direction the electron flow. The control grid determines the color combination on the screen. The stream of electrons moves from left to right, top of the screen to build an image.

LCD staging uses a layer of the liquid crystal material. Sandwiched between two electrode grids. One arranged in columns and the other in rows. These grids surrounded by a layer of polarizing material made of plastic or glass. It aligns these polarizing layers to prevent light from passing. When the electrodes not activated.

To produce an image, light passes through the first polarizing layer. As the light passes through the liquid crystal material. It changes the polarity to allow it to pass through the second polarizing layer. This idea by manipulating the electrode grid. The pixels composed of liquid crystal cells that change. Give direction of light passing through them in response to the electrode grid.

Today’s liquid crystal display use a so-called thin film transistor (TFT) technology. It places transistors at each intersection of the electrode grid. Which improves the signal and, so, the image quality. It knows this as active matrix visualization. Unlike the old technology is known as passive matrix visualization.

There are many features to consider when choosing a display. The most important. The screen size, resolution, point step, refresh rate and response time. The screen size refers to the diagonal length of the screen surface. Resolution is the number of pixels the display can displays, such as 640 × 480, which means 640 pixels and 480 pixels. The more pixels that displayed, the sharper the image. The distance between the points is the distance between the points, expressed in millimeters. Example, 25 mm. Lesser the number, the genuine the image. The refresh rate of the CRT display or the response time of the LCD staging is the speed. Which the display builds the image. The faster the response time or refresh rate, the better the image.

LCD display take up much less space and are lighter than CRT displays. Besides, LCD displays consume less power. They are more expensive. Although in the long run, they can compensate by reducing power usage.

CRTs have a higher refresh rate than the LCD display response time. Which reduces eye strain and may prefer for people who spend much of time in front of the computer. CRT displays can set to shows at various resolutions. While LCD display use only one resolution, called native resolution. This can cause problems for advanced games and graphics screens.

Refresh rate of the CRT display or the response time of the LCD staging is the speed. Which the displays builds the image. The faster the response time…

Although the first price of liquid crystal displays was higher. Lower than that of CRT displays a few years ago, it has improved the technology. LCD display are comparable to CRT displays price and screen quality. Liquid crystal display are future displays that will make CRT displays obsolete.
