1. INTRODUCTION

1.1 Scope

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')/[(9 u'/2) - 12v' + 9]

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

If the input timing is not a supported timing listed above but within the supported frequency
range (Horizontal: 61KHz,Vertical: 75Hz), this monitor will select a closest mode instead. But
the display quality may not be optimized.
If the input timing over the supported frequency range, a message “Out of Range” will be
shown.
