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 - PLL(Phase Locked Loop) screen easily with this. During progressing ADC, Device makes clock synchronizing HSYNC with Video clock - Image Lock This means "Fineness adjustment" in LCD - Inverter Monitor, the features are "Fine" and "Coarse" 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 - AC Adapter control phase difference. Device that converts AC (90V~240V) to DC (+12V or 14V) - COARSE This is a adjustment by tuning with Video colck - SMPS(Switching Mode Power Supply) and PLL clock. Switching Mode Power supply. This design technology is used to step up/down - DVI (Digital Visual Interface) the input power by switching on/off This provides a high speed digital connection for visual data types that is display technology - FRC(Frame Rate Controller) independent. this interface is primarily forcused at Technology that change image frame quantity providing a connection between a computer and displayed on screen for one second. its display device. 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 This provides a high speed digital connection for to other resolution.(ex. 640 x 480 to 1024 x768) visual data types that is display technology independent. this interface is primarily forcused at providing
