1.1 SCOPE
This document defines the design and performance
requirements for an 15" inch diagonal , flat panel monitor .
The display element shall be a 1280x800 resolution
TFT-LCD (Thin Film Transistor Liquid Crystal
Display).262K-color(AU),images are displayed on the
panel.Video input signals are analog RGB (0.7Vp-p).
When the system is powered-on , previously stored
screen parameters for a pre-defined mode will be
recalled if the operating mode is one of stored in
memory( 8 factory , 8 users timing ).This monitor
operates normal by non-interlaced mode. DDC
(Display Data Channel) function is DDC2Bi compliance
Power saving function complies with the DPMS
(Display Power Management Signaling) standard.
1.2 GENERAL REQUIREMENTS
1.2.1 Test Condition
Brightness level & contrast level max. Full white
pattern test mode following spec. Warm up more than
1 hr, ambient light < 10 Lux , Luminance meter CA110
or BM7 or same equipment .
1.2.2 Test Equipment
The reference signal source is a calibrated Chroma
2135 video generator or higher.The use of other
signal generators during qualification and production
is acceptable provided the product complies with this
specification.
1.3 ELECTRICAL
This section describes the electricalrequirement of the
monitor.The block diagram in Figure1 illustrates the various
electrical sub-system.

1. Product Specification

The LCD monitor consists of an interface board , a power board
, a function key board and two speaker (1W)(with audio)
The interface board will house the flat panel control logic ,
brightness control logic, audio function control (option), key
function control, DDC and DC to DC conversion to supply the
appropriate power to the whole board and LCD flat panel , and
transmitting LVDS signals into LCD flat panel module to drive
the LCD display circuit .
The power board will support main power DC 3.3V to interface
board, and drive the two CCFLs (Cold Cathode Fluorescent
Tube).The interface board provides the power ON / OFF control
over the whole monitor and control for DPMS LED indicator to
function key board.
