1.0 Introduction This document defines the electromechanical parameters and operating characteristics for a 12’1” Active Matrix Liquid Crystal Display (AMLCD) based product, hereafter referred to as the Monitor. It is intended for operation in high ambient light, outdoor environment. The Monitor has a scaleable video format capable of displaying a minimum of VGA (640 x 480) through XGA (1024 x 768) input resolution. The Monitor can be driven directly from the standard analog Video Graphics

2.8 LCD Controller Board The LCD Controller Board incorporates components necessary to drive the LCD Panel (Section 6.7). Accepting VGA and VESA video standards (Section 1.2), these video signals are digitized and processed for the LCD Panel. Due to the LCD Panel’s fixed video resolution (800 x 600), the LCD Controller Board will perform independent horizontal and vertical zoom and shrink scaling of specified video resolutions less than or greater than the LCD Panel’s video resolution

where 0-mv is minimum luminance. Rise and fall times for the input signal (10% - 90%) will be ?5-ns (Figure 6). When terminated with a 75-ohm termination, the dark state (black level) is defined as a level between 0-mv and 10-mv. The white state (full white) is dependent on the VGA controller driving the Monitor. Maximum levels may range from 550-mv to 714- mv. Nominal 680-mv input voltage shall be defined as the default for supplier setup requirements. Displayed image intensity and co
