It contains millions of tiny red, green and blue phosphor dots that glow when struck by an electron beam that travels across the screen and create a visible image.

The amount of light the LCD monitor produces is called brightness or luminance, measured in cd/m 2 (candela per square metre).Ī CRT monitor is similar to a traditional TV set. Active-matrix LCDs use TFT (thin film transistor) technology, in which each pixel has its own switch. The crystals block the light in different quantities to create the image.

Monitors with a 32-bit depth are used in digital video, animation and video games to get certain effects.Īn LCD is made of two glass plates with a liquid crystal material between them. For example, an old VGA monitor with an 8-bit depth can generate 256 colours and a SuperVGA with a 24-bit depth can generate 16.7 million colours. This depends on the number of bits used to describe the colour of a single pixel. LCD monitors use a DVI (digital video interface) connection.Ĭolour depth refers to the number of colours a monitor can display. CRT monitors use a VGA (video graphics adapter) cable, which converts digital signals into analogue signals. Inside the computer there is a video adapter, or graphics card, which processes images and sends signals to the monitor. High- definition TV also uses this format.The viewable screen size is measured diagonally, so a 19"screen measures 19" from the top left to the bottom right. For widescreen LCD displays, the aspect ratio is 16:9, very useful for viewing DVD movies, playing games and displaying multiple windows side by side. Historically, computer displays, like most televisions, have had an aspect ratio of 4:3 - the width of the screen to the height is four to three. Two measurements describe the size of your display: the aspect ratio and the screen size.

A typical resolution is 1024x768.Ī pixel is a combination of red, green and blue subpixels It is expressed by identifying the number of pixels on the horizontal and vertical axes. Resolution refers to the number of dots of colour, known as pixels (picture elements), contained in a display. Because of their slimmer design and lower energy consumption, LCD monitors (also called flat panel or flat screen displays) are replacing CRTs.

Most desktop displays use Liquid Crystal Display (LCD) or Cathode Ray Tube (CRT) technology, while nearly all portable computing devices, such as laptops, incorporate LCDs. Most-used output device on a computer.They provide instant feedback by showing you text and graphic images as you work or play. Displays, often called monitors or screens, are the
