When selecting and implementing a touch screen technology solution, there are numerous requirements and design factors to consider and a complex array of solutions and options.
A D Metro can assist you in prioritizing those requirements that are most important and relevant to your application.
Temperature, humidity, etc.
Finger, stylus, pen, tools, medical gloves, industrial gloves, winter gloves, edge of credit card, etc.
Exposure to scratches, abrasion, welding sparks, cigarette butts, etc.
Chemicals, dirt, dust, cleaning agents, etc.
Must it be resistant to vandalism
Military, cockpit or first responder, etc.
UL, FCC, MIL-STD, MIL-SPEC, EN, ROHS, etc.
LED’s EMI, LCD, optical bonding
Mass production, limited production runs, manufacturing location, delivery times
Industry standard size, or custom form factor
Number of touches, frequency of touches, years of operation, etc.
Simple press-to-select, multi-touch, or gesture based interactions
Anti-glare, anti-reflective, night-sight, full plus reflected sunlight, chopped sunlight (helicopter)
Plastic bezel, metal bezel, gaskets, adhesives, bonding, etc.
Controller embedded on motherboard or separate control module, USB, I2C, RS-232

Understanding touch screen technologies and the differences between them is important when contemplating design options and trade-offs.
Pressure Activated sensors overlay the display. They use pressure activation to create a contact between conductive layers and resistance to locate the touch point.
PCAP sensors use conductive coatings, high frequency signals and changes in capacitance to detect the proximity of a finger and its location.
Peripheral Sensors detect touch as a disruption of a signal over a display surface; without embedded sensing in the glass they offer the highest optical clarity.
