3 TouchScreen thoughts! Is één van de oplossingen voor HMI, niet dé oplossing. Er is geen perfecte HMI-oplossing. Tevens: elke applicatie heeft zijn eigen HMI methode Touchscreen zal bestaande schakelaars en menbramefolieprojecten voor 90% vervangen. Ook zonder LCD kan touchscreen worden toegepast. Grote vrijheid in design. Gebruiker kan zelf de HMI bepalen. Eenvoud in constructie plakwerk vervangt schroeven! Belangrijk toegepast component: transparent conductor Ink (Indium Tin Oxide) Vinger én styluspen Touchscreen voor slechtzienden? Constructie eenvoudig

4 Types of Analogue Touch Screens Five basic formats (mainstream) Resistive (dual-layer) Projected Capacitive Surface Capacitance (single-layer) Surface Acoustical Wave (SAW) Infra-red (IR)

5 Other Emerging touchscreen technologies And 10 more..

6 Technology Comparison Damage Resistant Weather Resistant Material Diversity Size Scalability Longevity Low Cost Infrared Resistive Surface Acoustic Wave (SAW) Surface Capacitance Projected Capacitance Worst Best

7 Technology Comparison Resistive - Tends to collect dust and dirt - Added cost to make waterproof - Custom button shapes add cost Infrared - Weak mechanical performance - Membrane wears down and cracks - Sensitivity decreases Projected Capacitive + Moisture resistant + Full freedom on button design + No performance degradation over time + Cost effective solution

10 Market Analysis

11 Keuze touchscreen Ergonomie het bedieningsgemak maakt een apparaat succesvol. de computer gaat voor ons denken. alleen de toetsen en de informatie waar het om gaat worden getoond Styling het uiterlijk, het design bepaald de aai-factor Innovatieve constructie maakt apparaat compleet Hype de gebruiker wil de nieuwste technologie Door Consumarization meer tablet-achtige bediening op het werk. Prijs touchscreen is soms 50% van de productiekosten Leverbaarheid markt wordt overspoeld door displays en TS-technologieën (prijsverlaging)

12 Keuze touchscreen Touchscreen met front = 50% van de productiekosten

13 Multi-touch? 2-touch 4-touch 10-touch 10 tot 100 touch Heeft de gebruiker multitouch nodig? Nee, niet echt! - Gaming - Gadgets - Musea - Multi-user - Oplossing ongewenste invoer (handpalm etc) Software: Windows 7 supports multi-touch throughout the OS and is structured to support an unlimited number (~100) of simultaneous touch points Android, ios and Linux support 4-5 touches

18 Projected Capacitive Touchscreen (PCTS)

19 PCTS Ideal for applications requiring Sensing through thick overlays No calibration Multi-touch detection E-field forced above sensing surface Requires patterned ITO Single or dual-layer Creates multiple sensing elements Sense-pads must be small (6-10mm) for resolution Advantages Disadvantages Determined by size of finger No calibration required device remains More complex production (2-layer) and accurate over PVT and life connection Capable of simultaneous detection of multiple finger presses works through thicker material (eg gloved hands) Low sensitivity to ITO resistance if Sigma- Delta, Successive Approximation or similar methods used Wide connection cable, typical mobile phone panel would require > 15 wires Sensitive to some types of measurement

20 PCTS

21 PCTS Self capacitance Mutual capacitance Older technology Newer technology Industrial market Consumer market 1 2 touch Multi finger touch Super SNR ratio Normal SNR ratio Simpler lowcost controller More complex, higher cost controller Waterproof No waterproof Best EMC specifications Difficult EMC specifications Het verschil zit in de firmware van de controller. Niet in de touchscreensensor.

29 PCTS Cypress Quality Highest SNR (signal/noise reduction) Fastest Refresh & Scan Rates Lowest Power Consumption Superior Accuracy & Multi-Finger Linearity Unmatched Advanced Features Best touch performance Single chip solution Customer always perform with newest firmware Unrivaled Touch Leadership Cypress has the world's broadest portfolio of touchscreen solutions. More companies have adopted the technology than anyone else in the industry. They have been granted dozens of touchscreen patents, and have hundreds more touch-specific patents pending. The continued leadership in the touchscreen space means that they respond to new challenges and market trends with truly innovative solutions.

30 Unique features: Self and Mutual capacitance sensing on the same chip. Hover: Senses and tracks a finger hovering above the surface of the touchscreen Works with gloves and long fingernails. Opens a new world of UI possibilities for 3D displays, gaming applications, and more SLIM Single-Layer Independent Multitouch Sensor for screens up to 4.5 Slashes manufacturing cost with only one ITO layer and no bridges No bezel required for borderless designs Display Armor Developed specifically to overcome display noise to detect and neutralize noise No air gaps or shields needed Charger Armor Unmatched noise immunity - up to 95 Vpp Improves SNR and reduces phantom touches Works effectively with the noisiest third-party chargers for noticeably improved performance Waterproofing Works with wet or sweaty fingers and isn't affected by water on the surface Devices in production today use TrueTouch to meet strict IP-67 waterproofing standards 1mm Stylus Support (point as small as 1mm) PCTS Cypress

31 PCTS Firmware Software (hexfile -licensed library) in de controller dat aangepast is voor de touchsensor / applicatie. - Vorm en afmeting - CTS-sensor - Aantal rijen en kolommen - Vorm ITO rijen en kolommen - Invloed LCD panel (bezel/ verlichting etc.) - Invloed magnetische straling - Waterbestendigheid - Communicatie usb/i²c - Pinning chip - Treshold etc Aankopen of zelf maken (Licentie) Standaard touchscreen/controller = Firmware gratis meegeleverd

32 Voordelen Clicktouch Projected Capacitive Touchscreen 1. Rijen en kolommen aansluiting tweevoudig uitgevoerd (= contact ITO rijen aan twee zijden) geen uitval, bij bv doorboren blijft deze aan weerskanten functioneren 2. Blijft functioneren bij glasbreuk (Er hoeft niet meteen een servicemonteur te komen).clicktouch ITO pattern robuuster en stabieler. 3. Montage op Glas, PMMA of Polycarbonate 4. Eenvoudig te combineren met buttons, slider en wheels 5. Minimaal gevoelig voor stress. 6. Minimaal gewicht door toepassing foliesensor 7. Zeer grote signaal/ruis verhouding 8. Grotere temperatuurbereik vanwege toepassing ITO op film. 9. Waterproof (functioneert bij stromend water) 10. Supports hele dikke handschoenen 11. Auto-tuning 12. Auto-Shielding geïntegreerd (oa geen last van LCD s en EMI > industriële specificaties) werkt probleemloos met RFID 13. Slechts 1 aansluitstaart (vereenvoudigd assemblage) 14. Staart gemonteerd op film en niet op hardglas: minder kans op breken. 15. Aansluitstaart kan naar wens op elke positie geplaatst worden. (vrijheid in constructie) 16. Keuze uit: chip op eigen besturing of standaard controllerboard

33 Voordelen Clicktouch Projected Capacitive Touchscreen 17. Besturing met slechts 1 lowpower chip 18. Chipfabrikant Cypress. Unieke samenwerking Clicktouch-Cypress. Cypress is een van de grootste chipfabrikanten in de wereld en grootste van Projected capacitief touchscreen Chips (Apple, Sony, Nokia, Philips, HP etc). 19. Chip uit voorraad verkrijgbaar via de bekende distributeurs (Arrow, Future, Silica, Farnell, Mouser, Digikey ) 20. Cypress-chips zeer prijsgunstig 21. Keuze uit self-sensing, mutual-sensing en combinatie van deze twee. Selfsensing is multigesture, Mutualsensing is multitouch tot 10 vingers 22. Supports alle industriële specificaties 23. Ook standaard touchscreen (geen ontwikkelkosten). Let op: sommige LCD's hebben afwijkende afmetingen inch self capacitance inch mutual 24. Oók afwijkende maten en positie/lengte staart leverbaar. 25. Clicktouch/Cypress eigen ontwikkeling met 12 jaar ervaring. 26. Ondersteuning touchscreen, controller en firmware in eigen huis.

34 Water immunity Waterproof sensing is important in the white goods, small home appliances, automotive applications, various industrial systems Water films or drops increase the sensor capacitance, causing the possible false touch detection Two Levels of Waterproof No false trigger in presence of water Button work well with covered water film Watch the demo on de Clicktouch stand Cypress PSoC support both by hardware!
