Reverse Scan Function

Mitsubishi Electric's TFT-LCD modules with twisted nematic (TN) architecture have a reverse scan feature that enables optimization of the vertical viewing cone.

As shown in the illustration below, when viewing from above in the normal scanning direction, a TFT-LCD module is displayed vividly without grayscale inversion, but when viewing from below the TFT-LCD module becomes hard to view due to grayscale inversion.

In this case, physically rotating the TFT-LCD module 180 degrees would improve the viewing performance of the display. However, the image is still upside down.

Mitsubishi Electric’s reverse scan function rotates the scanning direction of the TFT-LCD module by 180 degrees to correctly orient the image.

The reverse scan function allows customers the choice of optimum viewing direction without having to manipulate their software to adjust for scanning direction.

Some TFT-LCD modules with super wide viewing architecture also include the reverse scan function.

This allows customers to optimize cable locations.

Super-Wide viewing Architecture

TFT-LCD module viewing angles are an important performance feature.

Depending upon the usage environment, users will reference information shown on the TFT-LCD module from a variety of different heights, angles, and distances.

Mitsubishi Electric’s TFT-LCD wide viewing angles allow strong optical performance in any usage environment.

(Mitsubishi Electric defines viewing angle as the angle where contrast ratio is 10:1 or better.)
