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 Array (VGA) output on a personal computer (PC). It consists of a 12.1" viewable diagonal LCD Panel with optical elements, Cold- Cathode Fluorescent Backlight, Backlight Inverter Board, and LCD Controller Board. Cooling fans provide temperature stabilization within the Monitor’s operating environment. Two (2) chassis mounted connectors at the rear provide for video signal and DC power input connections. These components will be mounted in a fully enclosed chassis.

1.1Display Format

The Monitor is compatible with IBM VGA1 and VESA2 video standards. Its operating frequency range is 31.5 KHz56? .5 KHz horizontal; 60 Hz72? Hz (non-interlaced) vertical. Specific video resolutions supported are as follows:

For IBM VGA1 modes, the Monitor will accept 640 pixels horizontally; 400 or 480 lines vertically and 800 pixels or 1024 pixels horizontally, 600 lines or 768 lines vertically for the VESA2 modes. Figure 9 defines the video signal timing requirements.

The LCD Controller Board will automatically program itself, sensing incoming horizontal/vertical frequencies and sync pulse polarities to completely “fill” the active display area of the Monitor with the video resolution being presented. Section 4.4.1 (Video Mode Definitions) defines parameters for video resolution detection by the LCD Controller Board.

Note: IBM VGA1 modes with border and the 720 x 400 video resolution are excluded from completely filling the active display area horizontally. Only the first 640 pixels will be displayed.
