The frame is composed of picture elements just like a chess
board. Each horizontal set of picture elements is known as a
line. The picture elements in a line are transmitted as sine
signals where a pair of dots, one dark and one light can be
represented by a single sine. The product of the number of lines
and the number of maximum sine signals per line is known as the
total resolution of the frame. Higher the resolution the more
faithful the displayed image to the original image. But higher
resolution introduces technical problems and extra cost. So a
compromise should be reached in system designs both for
satisfactory image quality and affordable price.  Viewing
distance[edit]  For computing the lowest resolution which still
seems satisfactory to viewers, the key parameter is the viewing
distance, i.e., distance betwee
