Maximum TouchScreen Performance With AllTheOptions Bergquist MoreOptions IsSimplyOurPoint When the top layer is depressed making contact with the base layer it picks up the voltage data and carries it to the electronics Because the top film is working only as a pick up layer it can tolerate resistance changes without impacting the reliability of the touch points accuracy from the base layer It is for this reason the 5 Wire is able to withstand temperature humidity and mechanical stresses As a result 5 Wire touch screens are specified at over 35 million activations versus a typical specification of 1 million activations for other types of resistive technologies Better Optics Bergquist s 5 Wire touch screens offer an enhanced level of clarity and contrast Through a patented configuration of separator dots Bergquist has taken their optical performance a step further by significantly reducing the scattering of light within the touch screen itself This is accomplished using a dot separator treatment that is color indexed to the conductive coating and the dot structure allows light to pass through unobstructed Instead of scattering light the dot separators allow the light to pass through the substrates The enhanced contrast helps to provide a sharper image for improved readability of text and graphics for a superior display appearance Polyester Film ITO Coating

Screen Bergquist combines the durability of 5 Wire resistive technology with flexible offerings to meet nearly any application requirement Some of these options include Largest range of Sizes 2 4 to 23 Slim Perimeters Off Aspect Ratio Sizes Multiple Glass Options Variety of Top Film Options Wide Selection of Connectors Custom Flex Cables Durable Enough To Stand Up To Harsh Environments The 5 Wire touch screen is engineered to withstand harsh environ ments and is inherently the most durable resistive touch screen on the market Durability gives the user Drift free operation during temperature changes Ability to withstand 35 million activations in a single area It is the 5 Wire s unique construction and electrical functionality that gives it durability The 5 Wire utilizes the stable substrate of glass for both X and Y axis measurements This is in contrast to other resistive technologies such as 4 Wire and 8 Wire technologies that must use two opposing layers to create X and Y axis measurements Electrically the 5 Wire operates by supplying five volts to ground and toggling in both directions thus supplying the necessary X and Y axis measurements The sense line or 5th wire is connected to the top film substrate Side view stack up of a 5 Wire 5 Wire construction X and Y axis are both on the same base layer of glass Polyester Film With Resistive ITO Coating LCD Glass

the door to a wide variety of design options We allow you to build touch screens in dimensions and configurations that were previously precluded by technology or technique The touch screen overall dimensions are no longer determined by just standard sizes You can specify the size to meet your application from 2 4 up to 23 in standard and off ratio configurations Rather than making your application fit a standard design you can customize just about any feature to meet your needs Whether its size glass tail configurations or film Bergquist gives you options that mean business for your company Low Power Bergquist has taken the power draw of a typical 5 Wire down from 100mA to a range of 35 to 20mA depending on design making 5 Wire a practical solution for power sensitive devices Independent Controller Solutions Offer Customer Flexibility Where OEMs were once bound to the touch screen manufacturer for their 5 Wire electronics solutions this is no longer the case Today the required electronics are simple and accessible with off the shelf inexpensive electronic chip solutions for 5 Wire You now have independent controller solutions for greater flexibility A comprehensive offering of flex tail interconnect solutions including Berg Amp Zif with center pitch spacing from 0 039 1 0mm to 0 100 2 54mm in custom die cut shapes or standard lengths Quality Materials That Mean

offering some of the slimmest perimeters in the industry our 5 Wire touchscreen design readily fits your application It takes up less space and allows you to convert easily from 4 and 8 Wire into 5 Wire Whether it is a new design or retrofit our 5 Wire fits Size Offerings The unique flexibility of the Bergquist 5 Wire pattern has changed the rules for 5 Wire size offerings Where once 5 Wire was only offered in diagonal sizes over 6 and standard aspect ratios of 3 4 Bergquist 5 Wire sizes are available as small as 2 4 and as large as 23 in standard 3 4 aspect ratio as well as off aspect ratios Select The Right Film For Your Application Bergquist offers a wide variety of films to match your individual application The film choice and best solution is dependent on your unique application which is why we work with you to understand your environment Some of the items we take into account include typical lighting conditions brightness and type of display viewing angle desired and separation space from touch screen to display Our standard films come with a 4H rated hard coat the toughest coating commercially available for touch screens today Our conductive top films include high contrast gloss diffused and several enhanced transmission types Emerging Market Opportunities The unique flexibility of the Bergquist 5 Wire touch screen has opened new market opportuni ties such as PDAs GPS systems entertainment and portable hand held data collection markets The Bergquist 5 Wire can be configured in nearly any size including sizes as small as 2 4 With its very low power draw it makes an ideal solution for rugged portable hand held devices in either small or large diagonals The flexibility in our pattern makes most emerging hand held applications possible without mold or significant design changes on the part of the manufacturer Off aspect ratio sizes are also available and are of particular interest to these markets due to its elongated landscape view POINTS OF
