Many medical devices rely on a display or user-interface module to relay information to the user.
In general, monochrome display formats for passive-matrix displays feature 16 levels of gray. This resolution of gray levels is adequate for viewing most natural images. These examples show the applicability of the medical imaging device in a Web browser type of application. The true power of gray scale is to bring depth to the passive-matrix display environment. The method of generating these gray levels has resulted in significant flicker, low viewing angle, and reduced contrast ratio.
