1.1 SCOPE
This document defines the design and performance
requirements for a 24W inch diagonal , flat panel monitor
.The display element shall be a WUXGA (1920x1200)
resolution TFT-LCD (Thin Film Transistor Liquid Crystal
Display).16.7M color(RGB Hi+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( 24 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
AMLCD: LTM240CT01
LTM240CT03
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 electrical requirement of the
monitor. The LCD monitor consists of an interface board , a
power board , a function key board. The interface board
wil l 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.
1.3.1 Interface Connectors
1.3.1.1 Power Connector and Cables
The AC input shall have an IEC/CEE-22 type male
power receptacle for connection to mains power.
The power cord shall be with length of 1.8+/-0.005
meters.
1.3.1.2 Video Signal Connectors and Cable
The signal cable shall be 1.8
0.005 meters long.
At the end of the cable shall be a molded-over,
shielded,triple row, 15 position, D-subminiature
connector. The CPU connection shall have captive
screw locks, which will be adequate for hand
tightening. The monitor connection may use small
screws.
