Method and apparatus for displaying a screen separator line

摘要

Method and apparatus for displaying a horizontal screen separator line between two screen areas. A first step operates a display screen controller (12) in a split screen mode of operation so as to display a first screen area (3) at an upper portion of a display screen (18) and a second screen area (4) at a lower portion of the display screen. The step of operating further includes a step of reading data from a screen memory (42) and displaying rows of corresponding alphanumeric characters. Each character is displayed as a plurality of image pixels arranged along a first number of horizontal scan lines. A further step displays a horizontal visual separator (2) between a last row of the first screen area and a first row of the second screen area. The step of displaying the horizontal visual separator includes the steps of (a) reading data from the screen memory and beginning a display of a row of corresponding visual separator characters; and (b) terminating the display of the row of corresponding visual separator characters after displaying a second number of horizontal scan lines that is less than the first number of horizontal scan lines.
