1.1 SCOPE
This document defines the design and performance
requirements for an 20/22W inch diagonal , flat panel
monitor .The display element shall be a WSXGA
(1680x1050) resolution TFT-LCD (Thin Film Transistor
Liquid Crystal Display).16.7M color(RGB 6bits+FRC)
images are displayed on the panel.Video input signals are
analog RGB (0.7Vp-p). When the systemis powered-on ,
previously stored screen parameters for a pre-defined
mode will be recalled if the operating mode is one of stored
in memory( 19 factory , 9 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.

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 DC5V to interface
board, and the power DC5.3V to audio function power of
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.
