Display Armor offersTHE PLUG ON CHARGER NOISE.two distinct methods to detect and neutralize noise,Noise enters the touchscreen system through apower supply, such as a mobile handset’s batterycharger, in the presence of touch. The mobile deviceindustry has established EN standards for maximumtouchscreen controller, so it doesn’t need shields or airensuring a high-performance user interface no matterhow loud the environment. That makes TrueTouch theideal solution for all types of stackups, including directlamination, on-cell, and in-cell.Charger Armor and Display Armor arebreakthrough proprietary technologies that ensurehigh performance from touchscreen devices in thepresence of extreme noise.As touchscreen-enabled devicesbecome more ubiquitous, it’s importantto make touchscreens more affordableto manufacture and to purchase.Cypress is here to help designers withan unmatched portfolio of singlelayer touchscreen solutions to bringmultitouch to the masses. From ournew SLIMTM (Single-Layer IndependentMultitouch) sensor for unbelievably thindesigns with full multitouch functionality,to our Gen2 single-layer sensor forlower-cost touchscreen systems, there’sa device for every application.Eliminating the second sensor layercan save manufacturers 40 percent onsensor costs. It also allows the creationof a new wave of exceptionally thindevices.charger noise and TrueTouch easily exceeds them.However, for chargers that can emit noise at 20times the spec and beyond, we have ChargerArmor. It’s an adaptive technology that listens forcharger noise and activates when it surpasses apreset threshold to effectively deal with both periodicand broadband noise. The result is truly revolutionarycharger noise immunity to the market.4 touch.cypress.com5
