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.

The product specification demonstrate all of the model:
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 resolution
TFT-LCD (Thin Film Transistor Liquid Crystal
Display).16.7M color(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( 2213 factory timing mode).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
1.2.1Test 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
1.2.2Test 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.
