1.INTRODUCTION

1.1Scope

This specification defines the requirements for the 15” MICRO-PROCESSOR based Multimode supported high resolution color LCD DISPLAY, This LCD DISPLAY can be directly connected to general 15 pin D-sub VGA connector, eliminates the requirement of optional special display card. It also supports VESA DPMS power management and plug & play function. There is a build-in stereo audio amplifier with volume control to drive a pair of speakers.

1.2 Description

The LCD DISPLAY is designed with the latest LCD technology to provide a performance oriented product with no radiation. This will alleviate the growing health concerns. It is also a space saving design, allowing more desktop space, and comparing to the traditional CRT monitor, it consumes less power and gets less weight in addition MTBF target is 20k

hours or more.

2.1.1 MEASUREMENT SYSTEMS

The units of measure stated in this document are listed below: 1 gamma = 1 nano tesla

1 tesla = 10,000 gauss cm = in x 2.54

lb = kg x 2.2

degrees F = [°C x 1.8] + 32 degrees C = [°F - 32]/1.8 u' = 4x/(-2x + 12y + 3)

v' = 9y/(-2x + 12y + 3)

x = (27u'/4)/[(9u'/2) - 12v' + 9] y = (3v')/[(9u'/2) - 12v' + 9]

nits = cd/(m2) = Ft-L x 3.426 lux = foot-candle x 10.76
