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