Liquid crystal displays come in a variety of aspect ratios to fit specific applications. Aspect ratio is defined as the ratio of the horizontal dimension to the vertical dimension of the active area of a display and is typically expressed as:
Aspect Ratio = horizontal dimension : vertical dimension
The dimensions are usually not the real dimensions of the active area but are expressed in terms of the "least common denominator". For example conventional video displays and most computer displays have an aspect ratio of 4:3. The actual dimensions could be 4 inches by 3 inches or it could be 40 inches by 30 inches. In both cases, the aspect ratio is 4:3. Another aspect ratio that is common (especially for HDTV) is 16:9. For specialized applications other aspect ratios may be used. Examples would be displays designed to fit in "industry standard" size such as a "single DIN" size for the automotive industry.
