Mitsubishi Electric’s standard industrial LCD modules have the ability to reverse scanning direction, which enables the display to be used for maximum visibility in either of two directions. For example, as shown in the illustration, when viewing from above in the normal scanning mode, the display colors do not reverse; however, when viewing from below, the color reverses, making it difficult to view the display. By rotating the display position of a Mitsubishi Electric module by 180 degrees, the view from below is improved with the image still reversed. By then reversing the scanning direction, the image is corrected while the display position is reversed. The reverse scan function allows the choice of optimum viewing direction.

Sometimes industrial applications require that displays be set in different locations while still maintaining an optimum viewing angle (upside down with reverse scan). When a display is designed symmetrically from its center point, the module can be physically reversed without the need to change the mountings. This design has been incorporated into our 6.5" VGA, 8.4" VGA, 12.1" SVGA, 12.1" XGA, and 15.0" XGA modules.
