1.1 Scope:
This document defines the design and performance
requirements for the Liteon standard 17" wide flat
panel monitor. The display element shall be a 17" inch
diagonal, WXGA (1440 x 900) resolution, TFT-LCD
(Thin Film Transistor Liquid Crystal Display). Video
input signals are Analog D-sub with non-interlaced
signaling. Power saving function complies with the
DPMS (Display Power Management Standard).

1.1.2 Optical Characteristics

The panel model name is HSD170MGW1-A
supplied by Hannstar.
1.2 General Requirements:

1.2.1 Test Condition

Brightness level at max & contrast level at default
full white pattern test mode following spec. Warm
up more than 30min, ambient light < 1 Lux,
Luminance meter CA210 or BM7 or compatible
equipment.
1.2.2 Test Equipment
The reference signal source is a calibrated
Chroma 2326 or Quantum 801GD video
generator. The use of other signal generators
during qualification and production is acceptable
provided the product complies with this
specification.

The LCD monitor will contain an interface board, a
Power/Inverter board, and a function key board. The
interface block will house the flat panel control logic,
brightness control logic, and DC-DC conversion to
supply the appropriate power to the whole board and
LCD panel, and transmitting LVDS signals into LCD
Module to drive the LCD display circuit. The inverter
block will drive the two CCFLs (Cold Cathode
fluorescent Tube). The power block will provide the
DC power to interface board and LCD panel. The
function key block will provides the OSD control
signal, power ON/OFF and LED indicator to the
interface board.
