![]() ![]() ![]() Refresh rates are also sometimes described in units of cycles per second / Hertz (Hz). In raster scan systems refreshing is done at a rate of 60-80 frames per second. Stored intensity values are restored from frame buffer and painted on screen taking one row at a time.Each screen point is referred to as pixels. This memory area holds intensity values for all screen points. A memory area called refresh buffer or frame buffer stores picture definition. In raster scan system electron beam sweeps across the screen, from top to bottom covering one row at a time.A pattern of illuminated pattern of spots is created by turning beam intensity on and off as it moves across each row. Raster Scan Displays are most common type of graphics monitor which employs CRT.
