Exhibit 4 Brief Description of Circuit Functions Function Description for Hudson4 190P5 1. General 190P5 is the newest generation of Hudson 19 TFT Flat Panel Display Monitor. It designed with hyper integrity, LVDS interface feature. The monitor featured with analog signal input interface, and modularized as a display unit with embedded universal AC power supplies inside monitor main body. The power button and display control buttons (tact switch type) are on the bottom side of the monitor. The monitor shall support an internal scaler to automatically enable the monitor to display lower resolution video modes into 1280 x 1024 full screen display. The image can be adjusted through OSD control board. These adjustments can be stored on a board memory including 33 pre-set modes and 15 factory pre-set modes. 2.

Function block Scaler GM5120 (contains following functions): (1) Analog RGB input - Support up to SXGA 75Hz - On chip high-performance PLLs - High speed triple ADC (2) TMDSRx input
- Convert serial digital signal to parallel digital RGB signal, it can reduce EMI. (3) Format converter - Built in GPIO port, mode detection. - Convert the image data from ADC, TMDSRx or Video Decoder to LCD panel data format. - Zoom the input video to full screen display. - High quality zoom and shrink scaling engine (4) LVDS interface - Convert digital image signal to LVDS signal. (5) On-Screen display (OSD) controller (6) On-chip micro-controller (OCM) Inverter - Accept +12VDC voltage. - Provide 680Vrms voltage for CCFL. Power supply - AC adapter : AC power input (from 90VAC to 264VAC) can generate +12VDC +5VDC and +3.3VDC power
