14 Reference Infomation14-114 Reference Infomation14-1 Technical Terms-TFT-LCD(Thin film Transistor Liquid Crystal Display)ADC(Analog to Digital Converter)This is a circuit that converts from analog signal todigital signals.-PLL(Phase Locked Loop)During progressing ADC, Device makes clock syn-chronizing HSYNC with Video clock-InverterDevice that supplies Power to LCD panel lamp. Thisdevice generates about 1,500~2,000V.AC AdapterDevice that converts AC(90V~240V) to DC(+12V or14V)SMPS(Switching Mode Power Supply)Switching Mode Power supply. This design technol-ogy is used to step up/down the input power byswitching on/off-FRC(Frame Rate Controller)Technology that changes the number of frames dis-played on screen per second.TFT-LCD panel requires 60 frames per second.This technology is needed to convert input image to60 frames per second regardless input frame quan-tity.-Image ScalerTechnology that converts an input resolution toanother resolution.(ex. 640* 480 to 1024*768)-Auto Configuration(Auto adjustment)This is an algorithm to adjust monitor to optimumcondition by pushing one key.-OSD(On Screen Display)Customers can easily control the screen settingsusing the OSD.-FINEThe "Fine" adjustment is used to adjust visibility bycontrolling phase difference.-COARSEThis adjustment adjusts the display by tuning Videoclock and PLL clock.-DVI (Digital Visual Interface)This provides a high speed digital connection forvisual data types that is display technology inde-pendent. This interface is primarily forcused at pro-viding a connection between a computer andits display device.-L.V.D.S.(Low Voltage Differential Signaling)A kind of transmission method for Digital.It can beused from Main PBA to Panel.-T.M.D.S(Transition minimized Differential Signaling)a kind of transmission method for Digital.It can be used from Video card to Main PBA.-DDC(Display data channel)It is a communication method between HostComputer and related equipment.It enables Plug and Play between PC and Monitor.-EDIDExtended Display Identification Data PC can recog-nize monitor information such as Product data,Product name,Display mode,Serial number andSignal source, etc Data is recognised via DDC Linelinking PC and Monitor.-Dot PitchThe image on a monitor is composed of red, greenand blue dots. The closer the dots, the higher theresolution. The distance between two dots of thesame color is called the 'Dot Pitch'. Unit: mm-Vertical FrequencyThe screen must be redrawn several times per sec-ond in order to create and display an image for theDownloaded from www.Manualslib.com manuals search engine
