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 syn- chronizing 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 by - DVI (Digital Visual Interface) switching on/off This provides a high speed digital connection for visual data types that is display technology independent. this interface is primarily forcused at - FRC(Frame Rate Controller) providing a connection between a computer and Technology that change image frame quantity dis- its display device. played on screen for one second. Actually TFT-LCD panel require 60 pcs of frame for one second. - L.V.D.S.(Low Voltage Differential Signaling) so,this technology is needed to convert input a kind of transmission method for Digital.It can be image to 60 pcs regardless input frame quantity. used from Main PBA to Panel. - Image Scaler - DVI (Digital Visual Interface) Technology that convert various input resolution to This provides a high speed digital connection for other resolution.(ex. 640* 480 to 1024*768) visual data types that is display technology inde-
