flat panel displayFlat panel displays show alphanumeric information and graphics. The flat panel displays contain quite thin and entirely flat screens. Plasma displays, electro-luminescent displays, and liquid crystal displays (LCDs) are the three major flat panel technologies available in the market. LCD displays are the most dominant of the three due to the fact that they further have two types. One is active LCD display and the other is Passive LCD display. Specifications associated with flat panel displays include video standards, number of pixels, number of colors, pixel pitch, image resolution, aspect ratio, screen height and width, screen diagonal, viewing angles, and luminance.

Flat Panel Video Standards

There five video standards available for all the flat panel displays. These include VGA, SVGA XGA, SXGA, and UXGA. VGA is video graphic array. It is a standard for computers to support graphics and text. SVGA is super video graphic array. It is the enhanced version of VGA providing greater quality. XGA is extended graphic array. IBM developed this high-resolution standard in 1990. SXGA is super extended graphic array. This is the enhanced version of SGA with much more graphic capabilities. UXGA is ultra extended graphic array. A very high-resolution graphic standard set that is much more enhanced that XGA or SXGA.

Flat Panel Screen Specifications

Luminance refers to the brightness. It is measured as "per unit area luminous intensity projected in a given direction". Normally aspect ratios of available flat panel displays are 4:3 for standard resolution and 16:9 for high definition (HD) picture. Common image resolutions for Flat panel displays include 1600 X 1200, 1280 X 1024, 1152 X 864, 1024 X 768, 800 X 600, and 640.X 480. Number of pixels counts both horizontal vertical directions. In other specifications there are mounting styles, extra features, environmental parameters, and connections.
