The effect of such overlays allows a display to be used as an input device, removing the keyboard and/or the mouse as the primary input device for interacting with the display's content. Such displays can be attached to computers or, as terminals, to networks. Touchscreens also have assisted in recent changes in the PDA and Cell-Phone Industries, making these devices more usable.</div><div style="MARGIN: 0px auto 10px; TEXT-ALIGN: center">Technologies<br />There are a number of types of touch screen technology:<br />Resistive <br />A <a title="Resistive" href="http://en.wikipedia.org/wiki/Resistive">resistive</a> touch screen panel is coated with a <a title="Thin-film deposition" href="http://en.wikipedia.org/wiki/Thin-film_deposition">thin metallic</a> electrically conductive and resistive layer that causes a change in the electrical current which is registered as a touch event and sent to the controller for processing.<br />Some resistive panels can estimate the area (and hence the pressure) of a touch based on calculations from the resistances.<br />Resistive touch screen panels are generally more affordable but offer only 75% clarity<a title="Wikipedia:Citing sources" href="http://en.wikipedia.org/wiki/Wikipedia:Citing_sources">[citation needed]</a> (premium films and glass finishes allow transmissivity to approach 85%<a title="Wikipedia:Citing sources" href="http://en.wikipedia.org/wiki/Wikipedia:Citing_sources">[citation needed]</a>) and the layer can be damaged by sharp objects. Resistive touch screen panels are not affected by outside elements such as dust or <a title="Water" href="http://en.wikipedia.org/wiki/Water">water</a> and are the type most commonly used today.<br />Surface Acoustic Wave (SAW)<br />Surface Acoustic Wave technology uses <a title="Ultrasonic" href="http://en.wikipedia.org/wiki/Ultrasonic">ultrasonic</a> waves that pass over the touch screen panel. When the panel is touched, a portion of the wave is absorbed. This change in the ultrasonic waves registers the position of the touch event and sends this information to the controller for processing. Surface wave touch screen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.<br />Capacitive <br />A <a title="Capacitor" href="http://en.wikipedia.org/wiki/Capacitor">capacitive</a> touch screen panel is coated with a material, typically <a title="Indium tin oxide" href="http://en.wikipedia.org/wiki/Indium_tin_oxide">indium tin oxide</a> that conducts a continuous electrical current across the sensor. The sensor therefore exhibits a precisely controlled field of stored electrons in both the horizontal and vertical axes - it achieves capacitance. The human body is also an electrical device which has stored electrons and therefore also exhibits capacitance. When the sensor's 'normal' capacitance field (its reference state) is altered by another capacitance field, i.e., someone's finger, electronic circuits located at each corner of the panel measure the resultant 'distortion' in the sine wave characteristics of the reference field and send the information about the event to the controller for mathematical processing. Capacitive sensors can either be touched with a bare finger or with a conductive device being held by a bare hand. Capacitive touch screens are not affected by outside elements and have high clarity, but their complex signal processing electronics increase their cost.<br />Infrared <br />An <a title="Infrared" href="http://en.wikipedia.org/wiki/Infrared">infrared</a> touch screen panel employs one of two very different methodologies. One method used thermal induced changes of the surface resistance. This method was sometimes slow and required warm hands. Another method is an array of vertical and horizontal IR sensors that detected the interruption of a modulated light beam near the surface of the screen. IR touch screens have the most durable surfaces and are used in many military applications that require a touch panel display.<br />Strain Gauge <br />In a <a title="Strain gauge" href="http://en.wikipedia.org/wiki/Strain_gauge">strain gauge</a> configuration the screen is spring mounted on the four corners and strain gauges are used to determine deflection when the screen is touched. This technology can also measure the Z-axis. Typical application include protecting new touch-screen railway ticket machines from <a title="Vandalism" href="http://en.wikipedia.org/wiki/Vandalism">vandalism</a>.<br />Optical Imaging <br />A relatively-modern development in touch screen technology, two or more image sensors are placed around the edges (usually the corners) of the screen. Infrared backlights are placed in the camera's field of view on the other sides of the screen. A touch shows up as a shadow and each pair of cameras can then be triangulated to locate the touch. This technology is growing in popularity, due to its scalability, versatility, and affordability, especially for larger units.<br />Dispersive Signal Technology <br />Introduced in 2002, this system uses sensors to detect the <a title="Mechanical energy" href="http://en.wikipedia.org/wiki/Mechanical_energy">mechanical energy</a> in the glass that occur due to a touch. Complex algorithms then interpret this information and provide the actual location of the touch. The technology claims to be unaffected by dust and other outside elements, including scratches. Since there is no need for additional elements on screen, it also claims to provide excellent optical clarity. Also, since mechanical vibrations are used to detect a touch event, any object can be used to generate these events, including fingers and styli.<br />Acoustic Pulse Recognition <br />This system uses more than two piezoelectric transducers located at some positions of the screen to turn the mechanical energy of a touch (vibration) into an electronic signal. This signal is then converted into an audio file, and then compared to preexisting audio profile for every position on the screen. This system works without a grid of wires running through the screen, the touch screen itself is actually pure glass, giving it the optics and durability of the glass out of which it is made. It works with scratches and dust on the screen, and accuracy is very good. It does not need a conductive object to activate it. It is a major advantage for larger displays. </div><div style="CLEAR: both; TEXT-ALIGN: center"><a href="http://picasa.google.com/blogger/" target="ext"><img style="BORDER-RIGHT: 0px; PADDING-RIGHT: 0px; BORDER-TOP: 0px; PADDING-LEFT: 0px; BACKGROUND: 0% 50%; PADDING-BOTTOM: 0px; BORDER-LEFT: 0px; PADDING-TOP: 0px; BORDER-BOTTOM: 0px; -moz-background-clip: initial; -moz-background-origin: initial; -moz-background-inline-policy: initial" alt="Posted by Picasa" src="http://photos1.blogger.com/pbp.gif" align="middle" border="0" /></a></div>i_unhttp://www.blogger.com/profile/15911617755770750687noreply@blogger.com0tag:blogger.com,1999:blog-8939215073259582031.post-58857716562014013602007-07-10T09:42:00.001-07:002007-07-11T10:18:29.320-07:00Monitor Brand (for PC)<ul><li><a href="http://global.acer.com/products/monitor/lcd.htm">Acer</a></li><li><a href="http://b2b.sony.com/Solutions/category/displays?CP=sony_hm_nav_b2b_displays&ref=http%3A//www.sony.com/index.php">SONY</a></li><li><a href="http://www.viewsonic.com/">Viewsonic</a></li><li><a href="http://accessories.us.dell.com/sna/category.aspx?c=us&category_id=4009&cs=19&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;l=en&s=dhs">Dell</a></li><li><a href="http://www.samsung.com/global/business/lcdpanel/">Sumsung</a></li><li><a href="http://www.lge.com/products/category/list/monitor.jhtml">LG</a></li><li>etc</li></ul><p><strong><span style="font-family:trebuchet ms;color:#ff6600;">Monitor Brand (for CAR PC)</span></strong></p><ul><li><span style="color:#ff6600;"><a href="http://www.cartft.com/">http://www.cartft.com/</a></span></li></ul><p><span style="color:#ff6600;"></span> </p><p><strong><span style="font-family:trebuchet ms;color:#ff6600;">Manufacturers</span></strong></p><ul><li><a title="AU Optronics" href="http://en.wikipedia.org/wiki/AU_Optronics">AU Optronics</a> </li><li><a title="Barco" href="http://en.wikipedia.org/wiki/Barco">Barco</a> </li><li><a title="BenQ" href="http://en.wikipedia.org/wiki/BenQ">BenQ</a> </li><li><a class="new" title="BOE Hydis" href="http://en.wikipedia.org/w/index.php?title=BOE_Hydis&action=edit">BOE Hydis</a> </li><li><a title="Casio" href="http://en.wikipedia.org/wiki/Casio">Casio</a> </li><li><a title="Chi Mei" href="http://en.wikipedia.org/wiki/Chi_Mei">Chi Mei Optoelectronics</a> </li><li><a title="CoolTouch Monitors" href="http://en.wikipedia.org/wiki/CoolTouch_Monitors">CoolTouch Monitors</a> </li><li><a title="Corning Inc." href="http://en.wikipedia.org/wiki/Corning_Inc.">Corning Inc.</a> </li><li><a title="Eizo" href="http://en.wikipedia.org/wiki/Eizo">Eizo</a> </li><li><a title="HP" href="http://en.wikipedia.org/wiki/HP">HP</a> </li><li><a title="Fujitsu" href="http://en.wikipedia.org/wiki/Fujitsu">Fujitsu</a> </li><li><a title="International Display Works" href="http://en.wikipedia.org/wiki/International_Display_Works">International Display Works</a> </li><li><a title="LG.Philips LCD" href="http://en.wikipedia.org/wiki/LG.Philips_LCD">LG.Philips LCD</a> </li><li><a title="LXD Incorporated" href="http://en.wikipedia.org/wiki/LXD_Incorporated">LXD Incorporated</a> </li><li>Ocular Inc. </li><li>Optrex America, Inc. </li><li>Pacific Display </li><li><a title="Samsung Electronics" href="http://en.wikipedia.org/wiki/Samsung_Electronics">Samsung Electronics</a> </li><li><a title="Sharp Corporation" href="http://en.wikipedia.org/wiki/Sharp_Corporation">Sharp Corporation</a> </li><li><a title="S-LCD" href="http://en.wikipedia.org/wiki/S-LCD">S-LCD</a> </li><li><a title="Sony" href="http://en.wikipedia.org/wiki/Sony">Sony</a> </li><li><a title="Viewsonic" href="http://en.wikipedia.org/wiki/Viewsonic">Viewsonic</a> </li><li><a title="Xerox" href="http://en.wikipedia.org/wiki/Xerox">Xerox</a> </li></ul><p>TFT-LCD (Thin Film Transistor-Liquid Crystal Display) is a variant of <a title="Liquid Crystal Display" href="http://en.wikipedia.org/wiki/Liquid_Crystal_Display">Liquid Crystal Display</a> (LCD) which uses <a title="Thin-Film Transistor" href="http://en.wikipedia.org/wiki/Thin-Film_Transistor">Thin-Film Transistor</a> (TFT) technology to improve image quality. TFT LCD is one type of <a title="Active-matrix liquid crystal display" href="http://en.wikipedia.org/wiki/Active-matrix_liquid_crystal_display">active matrix</a> LCD, though it is usually synonymous with LCD. It is used in <a title="Television" href="http://en.wikipedia.org/wiki/Television">televisions</a>, <a title="Flat panel display" href="http://en.wikipedia.org/wiki/Flat_panel_display">flat panel displays</a> and <a title="Projector" href="http://en.wikipedia.org/wiki/Projector">projectors</a>.</p><p></p><p>Normal Liquid Crystal Displays like those found in calculators have direct driven image elements – a <a title="Voltage" href="http://en.wikipedia.org/wiki/Voltage">voltage</a> can be applied across one segment without interfering with other segments of the display. This is impractical for a large <a title="Display" href="http://en.wikipedia.org/wiki/Display">display</a> with a large number of picture elements (<a title="Pixel" href="http://en.wikipedia.org/wiki/Pixel">pixels</a>), since it would require millions of connections - top and bottom connections for each one of the three colors (<a title="Red" href="http://en.wikipedia.org/wiki/Red">red</a>, <a title="Green" href="http://en.wikipedia.org/wiki/Green">green</a> and <a title="Blue" href="http://en.wikipedia.org/wiki/Blue">blue</a>) of every pixel. To avoid this issue, the pixels are addressed in rows and columns which reduce the connection count from millions to thousands. If all the pixels in one row are driven with a positive <a title="Voltage" href="http://en.wikipedia.org/wiki/Voltage">voltage</a> and all the pixels in one column are driven with a negative voltage, then the pixel at the intersection has the largest applied voltage and is switched. The problem with this solution is that all the pixels in the same column see a fraction of the applied voltage as do all the pixels in the same row, so although they are not switched completely, they do tend to darken. The solution to the problem is to supply each pixel with its own <a title="Transistor" href="http://en.wikipedia.org/wiki/Transistor">transistor</a> switch which allows each pixel to be individually controlled. The low leakage current of the transistor also means that the voltage applied to the pixel does not leak away between refreshes to the display image. Each pixel is a small capacitor with a transparent <a title="Indium tin oxide" href="http://en.wikipedia.org/wiki/Indium_tin_oxide">ITO</a> layer at the front, a transparent layer at the back, and a layer of <a title="Electrical insulation" href="http://en.wikipedia.org/wiki/Electrical_insulation">insulating</a> liquid crystal between.<br />The circuit layout of a TFT-LCD is very similar to the one used in a <a title="Dynamic random access memory" href="http://en.wikipedia.org/wiki/Dynamic_random_access_memory">DRAM</a> memory. However, rather than building the transistors out of <a title="Silicon" href="http://en.wikipedia.org/wiki/Silicon">silicon</a> which has been formed into a <a title="Crystal" href="http://en.wikipedia.org/wiki/Crystal">crystalline</a> wafer, they are fabricated from a <a title="Thin film" href="http://en.wikipedia.org/wiki/Thin_film">thin film</a> of silicon deposited on a <a title="Glass" href="http://en.wikipedia.org/wiki/Glass">glass</a> panel. Transistors take up only a small fraction of the area of each pixel, and the silicon film is etched away in the remaining areas, allowing light to pass through.<br />The silicon layer for TFT-LCDs is typically deposited using the <a title="PECVD" href="http://en.wikipedia.org/wiki/PECVD">PECVD</a> process from a <a title="Silane" href="http://en.wikipedia.org/wiki/Silane">silane</a> gas precursor to produce an <a title="Amorphous" href="http://en.wikipedia.org/wiki/Amorphous">amorphous</a> silicon film. <a title="Polycrystalline silicon" href="http://en.wikipedia.org/wiki/Polycrystalline_silicon">Polycrystalline silicon</a> is also used in some displays where higher performance is needed from the TFTs, typically in very high resolution displays or ones where performing some data processing on the display itself is desirable. Both amorphous and polycrystalline silicon TFTs have very poor performance compared with transistors fabricated from single-crystal silicon.</p>i_unhttp://www.blogger.com/profile/15911617755770750687noreply@blogger.com0
