Resistive Touchscreens

Resistive touchscreens are widely used in industrial electronics, ATMs, kiosks, and medical devices. Unlike capacitive screens, they rely on pressure applied to the surface to register input.

Construction

• Two thin layers (typically PET film and glass) separated by spacers
• Both layers coated with indium tin oxide (ITO) conductive material
• When pressure is applied (finger, stylus, or tool), resistance changes and sensors calculate the touch coordinates

Types of Resistive Touchscreens

4‑Wire Analog

• Top and bottom layers with perpendicular electrodes (“busbars”)
• Provides voltage readings when contact occurs
• Cost‑effective and widely used

5‑Wire Analog

• Separate X and Y electrodes
• Improved durability and sensitivity compared to 4‑wire designs

8‑Wire Analog

• Combines features of 4‑wire and 5‑wire systems
• Offers enhanced accuracy and robustness
  
  

Keyflex resistive ITO touchscreens provide a flexible, reliable, and affordable solution for industrial, consumer, and medical applications.

Planar Resistive Touch Technology

• Enhancement of conventional resistive touchscreens
• Incorporates hardwired switching into the front surface
• Planar switch panels are optically bonded to the resistive layer and invisible to the user

Manufacturing Options

• Available in 4‑wire, 5‑wire, and 8‑wire resistive designs
• Can be supplied with or without a surrounding front decal
• Offered in gloss or anti‑glare finishes

Advantages

• Cost‑effective input solution
• Long lifespan and reliable performance
• Eliminates the need for keyboards or pointing devices
• Ideal for applications not exposed to harsh environments
