1.1 SCOPE
This document defines the design and performance
requirements for a 23W inch diagonal , flat panel monitor
.The display element shall be a 1920x1080 or a 2048x1152
resolution TFT-LCD (Thin Film Transistor Liquid Crystal
Display).16.7M colors(Hi-FRC) 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( 21 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 Ca210
or BM7 or same equipment .
1.2.2 Test Equipment
The reference signal source is a calibrated Chroma
2237 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.

1. Product Specification

The LCD monitor consists of an interface board, a power board
and inverter board, a function key board.
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 drive the two CCFLs (Cold
Cathode Fluorescent Tube).
The interface board provides the power ON / OFF
control over the power board.
Whole monitor to control the DPMS LED indicator to
function key board.
