Customer satisfaction is driven by user interface experience: touch matters!
When a touch interface doesn’t work right, the user experience colors the entire device. So how do you know whether you are better served by an off-the-shelf touch sensor solution or a custom solution made just for your application?
Some key attributes of your application can help you decide which approach is right for you:
Custom Touch Sensors
Custom capacitive touch sensors have many options for how it is designed, assembled, and operates to achieve the functionality that is right for your application. Don’t be afraid - a custom solution may actually lower your overall costs and improve your end-user experience.
- Applications that cannot tolerate false touch consequences
- Applications that need to be serviced for many years
- Applications with annual volumes under 100,000 units
Stock Touch Sensors
There is an overwhelming array of stock, off-the-shelf capacitive touch sensors available. Often listed as an option, display manufacturers offer touch sensors laminated directly onto the display and shipped as a single unit.
- Readily available if the standard sizes fit your application
- Very cost effective
Incorporating capacitive touch capabilities into a device using the standard option sensor can be cost effective if it meets all specifications and requirements for engineering, manufacturing, purchasing, and quality.
Typical characteristics of a standard, off-the-shelf touch sensor:
- Technology: ITO (Indium Tin Oxide) laminated
- with OCA (Optically Clear Adhesive)
- Controller: No option
- Tuning of the controller: No option
- Sensor design: No option
- Tail length and location: No option
There are 5 different aspects of the sensor to consider:
- Sensor pattern
- Sensor material
- Sensor size and shape
- Sensor tail location and length
- Integrated tail or flexible printed circuit with integrated controller
