- tft-lcd (thin film transistor liquid crystal display) adc(analog to digital converter) this is a circuit that converts from analog signal to digital signals. - pll(phase locked loop) during progressing adc, device makes clock synchronizing hsync with video clock - inverter device that supplies power to lcd panel lamp. this device generates about 1,500~2,000v. - smps(switching mode power supply) switching mode power supply. this design technology is used to step up/down the input power by switching on/off - frc(frame rate controller) technology that change image frame quantity displayed on screen for one second. actually tft-lcd panel require 60 pcs of frame for one second. so,this technology is needed to convert input image to 60 pcs regardless input frame quantity. - image scaler technology that convert various input resolution to other resolution.(ex. 640* 480 to 1024*768) - auto configuration(auto adjustment) this is an algorithm to adjust monitor to optimum condition by pushing one key. - osd(on screen display) on screen display. customer can control the screen easily with this. - image lock this means "fineness adjustment" in lcd monitor, the features are "fine" and "coarse" - fine "fine" adjustment is used to adjust visibility by control phase difference. - coarse this is a adjustment by tuning with video colck and pll clock. - dvi (digital visual interface) this provides a high speed digital connection for visual data types that is display technology independent. this interface is primarily forcused at providing a connection between a computer and its display device. - l.v.d.s.(low voltage differential signaling) a kind of transmission method for digital. it can be used from main pba to panel. - dvi (digital visual interface) this provides a high speed digital connection for visual data types that is display technology independent. this interface is primarily forcused at providing a connection between a computer and its display device. - 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 host computer and related equipment. it can make it plug and play between pc and monitor. - edid extended display identification data pc can recognize the monitor information as product data, product name,display mode,serial number and signal source,etc through ddc line communicating with pc and monitor. 14 reference infomation 14-1 14 reference infomation 14-1 technical terms
14 reference infomation 14-2 - dot pitch the image on a monitor is composed of red, green and blue dots. the closer the dots, the higher the resolution. the distance between two dots of the same color is called the 'dot pitch'. unit: mm - vertical frequency the screen must be redrawn several times per second in order to create and display an image for the user. the frequency of this repetition per second is called vertical frequency or refresh rate. unit: hz example: if the same light repeats itself 60 times per second, this is regarded as 60 hz. - horizontal frequency the time to scan one line connecting the right edge to the left edge of the screen horizontally is called horizontal cycle. the inverse number of the horizontal cycle is called horizontal frequency. unit: khz - interlace and non-interlace methods showing the horizontal lines of the screen from the top to the bottom in order is called the non-interlace method while showing odd lines and then even lines in turn is called the interlace method. the non-interlace method is used for the majority of monitors to ensure a clear image. the interlace method is the same as that used in tvs. - plug & play this is a function that provides the best quality screen for the user by allowing the computer and the monitor to exchange information automatically. this monitor follows the international standard vesa ddc for the plug & play function. - resolution the number of horizontal and vertical dots used to compose the screen image is called 'resolution'. this number shows the accuracy of the display. high resolution is good for performing multiple tasks as more image information can be shown on the screen. example : if the resolution is 1280 x 1024 , this means the screen is composed of 1280 horizontal dots (horizontal resolution) and 1024 vertical lines (vertical resolution). - s-video short for "super video." s-video allows up to 800 lines of horizontal resolution, enabling high-quality video. - external device input external device input refers to video input from such external video devices as vcrs, camcorders and dvd players, separate from a tv broadcast. - dvd a type of digital disk technology that takes up only the benefits of cd and ld, to implement a high resolution/quality, which enables the user to enjoy clearer images.
- connecting the monitor 14 reference infomation 14-3 1. connect the dc adapter for your monitor to the power port on the back of the monitor. plug the power cord for the monitor into a nearby outlet. 2-1. using the d-sub (analog) connector on the video card. connect the signal cable to the 15-pin, d-sub connector on the back of your monitor. 2-2. using the dvi (digital) connector on the video card. connect the dvi cable to the dvi port on the back of your monitor. 2-3. connected to a macintosh. connect the monitor to the macintosh computer using the d-sub connection cable. 3. turn on your computer and monitor. if your monitor displays an image, installation is complete. - you may get a blank screen depending on the type of video card you are using, if you connect simultaneously both the d-sub and dvi cables to one computer. - if you properly connect your monitor using the dvi connector but get a blank screen, check to see if the monitor status is set to analog. press power button to have the monitor double-check the input signal source.
