MAJOR IC INFORMATIONS (Display)
∫
IC2206 (SII861)
This is a DVI receiver.
The TMDS differential signal that is transmitted from the system cable is processed here to produce 24-bit
RGB signals, H and V sync signals, and DE signal in the odd and even numbers.
∫
IC4701 (IXA332WJ)
This is a QS driver for even.
Input signals of the DVI receiver are QS (Quick Shoot)-driven according to the temperature parameter from
the monitor microprocessor.
∫
IC4901 (IXA332WJ)
This is a QS driver for odd.
Input signals of the DVI receiver are QS (Quick Shoot)-driven according to the temperature parameter from
the monitor microprocessor. The H and V sync as well as DE signals coming from the DVI receiver are also
QS-driven and then be put out.
∫
IC4501 (IXA725WJ)
This is an LCD controller.
With the 24-bit RGB signals, H and V sync signals and DE signal, all coming from the QS drivers (odd and
even), the video data is sorted in the odd and even numbers for the right and left of the LCD panels and the
LCD panels are driven. This controller is intended to generate control signals for those tasks as well as the
brightness.
∫
IC4101 (IXA706WJ)
This TFT LCD gradation reference power IC has 18 gradation output buffer amplifier circuits, CMOS buffer
amplifier, and reference voltage source incorporated.
∫
IC2004 (IXA201WJ)
This monitor microprocessor has the following functions: monitor OSD control, thermistor-based panel
temperature detection, QS driver temperature parameter setting, LCD controller timing, brightness data setting,
monitor power control, power lines monitoring, remote control decoding, and OPC control.
∫
IC3803 (TA8184F)
This IC is designed to control the volume, balance, treble and bass.
The DC voltage is regulated for all these controls.
