14 Reference Infomation 14 Reference Infomation 14-1 Technical Terms - TFT-LCD - Image Lock (Thin film Transistor Liquid Crystal Display) This means "Fineness adjustment" in LCD ADC(Analog to Digital Converter) Monitor, the features are "Fine" and "Coarse". This is a circuit that converts from analog signal to digital signals. - FINE "Fine" adjustment is used to adjust visibility by - PLL(Phase Locked Loop) control phase difference. During progressing ADC, Device makes clock synchronizing HSYNC with Video clock - COARSE This is a adjustment by tuning with Video colck - Inverter and PLL clock. Device that supply Power to LCD panel lamp. this device gernerate about 1,500~2,000V. - DVI (Digital Visual Interface) This provides a high speed digital connection for - AC Adapter visual data types that is display technology Device that converts AC(90V~240V) to DC independent. this interface is primarily forcused at (+12V or 14V) providing a connection between a computer and its display device. - SMPS(Switching Mode Power Supply) Switching Mode Power supply. This design - L.V.D.S.(Low Voltage Differential Signaling) technology is used to step up/down the input A kind of transmission method for Digital.It can be power by switching on/off used from Main PBA to Panel. - FRC(Frame Rate Controller) - HDMI(high definition multimedia interface) Technology that change image frame quantity Superhigh speed multimedia interface that can displayed on screen for one second. incorporate grass digital audio and video signal Actually TFT-LCD panel require 60 pcs of frame that is not compressed and transmit. By standard for one second. so,this technology is needed to that replace existent composite, supermarket convert input image to 60 pcs regardless input video, analog interface with component video, is frame quantity. applied mainly to newly developed DVD player, HDTV, set top box etc..circuits is simple by handling as it is without c
