- TFT-LCD
(Thin film Transistor Liquid Crystal Display)
ADC(Analog to Digital Converter)
This is a circuit that converts from analog signal to
digital signals.
- PLL(Phase Locked Loop)
During progressing ADC, Device makes clock syn-
chronizing HSYNC with Video clock
- Inverter
Device that supply Power to LCD panel lamp. this
device gernerate about 1,500~2,000V.
- AC Adapter
Device that converts AC(90V~240V) to DC(+12V
or 14V)
- SMPS(Switching Mode Power Supply)
Switching Mode Power supply. This design tech-
nology is used to step up/down the input power by
switching on/off
- FRC(Frame Rate Controller)
Technology that change image frame quantity dis-
played on screen for one second.
Actually TFT-LCD panel require 60 pcs of frame
for one second.
so,this technology is needed to convert input
image to 60 pcs regardless input frame quantity.
- Image Scaler
Technology that convert various input resolution to
other resolution.(ex. 640* 480 to 1024*768)
- Auto Configuration(Auto adjustment)
This is an algorithm to adjust monitor to optimum
condition by pushing one key.
- OSD(On Screen Display)
On screen display. customer can control the
screen easily with this.
- Image Lock
This means "Fineness adjustment" in LCD
Monitor, the features are "Fine" and "Coarse"
- FINE
"Fine" adjustment is used to adjust visibility by
control phase difference.
- COARSE
This is a adjustment by tuning with Video colck
and PLL clock.
- DVI (Digital Visual Interface)
This provides a high speed digital connection for
visual data types that is display technology
independent. this interface is primarily forcused at
providing a connection between a computer and
its display device.
- L.V.D.S.(Low Voltage Differential Signaling)
a kind of transmission method for Digital.It can be
used from Main PBA to Panel.
- DVI (Digital Visual Interface)
This provides a high speed digital connection for
visual data types that is display technology inde-
pendent. this interface is primarily forcused at pro-
viding a connection between a computer and its
display device.
- T.M.D.S
(Transition minimized Differential Signaling)
a kind of transmission method for Digital.
It can be used from Video card to Main PBA.
- DDC(Display data channel)
It is a communication method between Host
Computer and related equipment.
It can make it Plug and Play between PC and
