The LCD module is designed so that the CCFL in it is
supplied by a Limited Current Circuit(IEC60950 or UL1950). Do not connect the
CCFL to hazardous Voltage Circuit.
Panel Source Identify
(1) ID label - The panel code “Q” for QDI panel and “T” for
Hannstar panel should be shown on the lower right side of ID label.
(2) UPC label - The panel code “Q” for QDI panel and “T” for
Hannstar panel should be shown on the lower right side of UPC label.
(3) Main board - The panel code “Q” for F/W version sticker
or silkscreen should show QDI panel and “T” for Hannstar panel on the main
board.
The MB board is a two-layer, single-landed. 12V DC power
from the power adapter enters the board through connector CN6. Other connectors
on the board are for audio speaker and button board .The VGA cable is a signal
cable that contains video signal, sync signal and DDC signal from PC VGA
adapter. This system board consists of 4 functional areas: flat panel
controller, flash ROM, power regulator and Audio amplifier.
Flat panel controller… NT68563HF (IC2)
The heart of the system board is the scalar chip of
NT68563HF. The scaler is a highly integrated flat panel display controller that
interfaces analog, digital, and video inputs. It combines a triple ADC, a DVI
compliant TMDS receiver, a multi-color on screen display (OSD) controller and
many other functions in a single chip. It provides user a simple, flexible and
cost-effective solution for various flat panel display products. The NT68563HF
operates at frequencies up to 205MHz (analog only), suitable for LCD monitor up
to UXGA resolution. The NT68563HF also build-in noise reduction function to
provide more stable video quality, spread spectrum to provide low EMI solution,
sRGB for video color space convert, post pattern for manufacture test.
