DESCRIPTION OF FUNCTION OF MAJOR ICs
� IC4701 (IXA332WJ) This IC is a QS driver for EVEN. It QS (Quick Shoot)-drives the input signal sent from the DVI receiver according to the temperature parameter setting from the monitor microcomputer. � EIC4901 (IXA332WJ) This IC is a QS driver for ODD. It QS (Quick Shoot)-drives the input signal sent from the DVI receiver according to the temperature parameter setting from the monitor microcomputer. In addition, after QS-driving the H and V synchronization signal and DE signal sent from the DVI receiver, it outputs the H and V synchronization signal and DE signal. � EIC4501 (IXA457WJ) This IC is a liquid crystal controller. It allocate the video data of the 24-bit RGB signal, H and V synchronization signal and DE signal sent from the QS driver (ODD and EVEN) to the left-side ODD and EVEN and the right-side ODD and EVEN of the liquid crystal panel and outputs the control signal for driving the liquid crystal panel. It also generates the control signal for dimmer control. � EIC4303 (IXA345WJ) This IC is a CPLD. Because the QS driver and liquid crystal controller are general-purpose FPGAs, it is used to make setting for each FPGA. After resetting, it reads the program data from IC4301 (flash) and makes setting for each IC through serial transmission. � EIC4105 (IXA350WJ) This IC is a gray scale reference power for TFT liquid crystal. It incorporates ten circuits of gray scale output buffer amp, a CMOS buffer amp and a reference voltage supply. � EIC2004 (IXA3491CE) This IC is a monitor microcomputer. It performs OSD control of the monitor section, detection of the panel temperature through the thermistor, setting of the temperature parameter for the OS driver, setting of the timing for the liquid crystal controller, setting of the dimmer control data, power control of the monitor section, monitoring of each power line, remote control decoding and OPC control.
