A touch panel manufacturer recently announced a 1.4 inch round resistive touch panel for small form factor devices. The round touch panel has a diameter of 1.4 inches or 36 millimeters, with a viewable display area of 1.2 inches, enabling compact touch interfaces for a range of commercial and industrial electronics.

The 1.4 inch round resistive touch panel uses a flexible resistive touch film for registering touch inputs. It supports single touch interactions, with an average touch response time of around 65 to 75 milliseconds. The panel provides an 4-wire analog resistive touch interface that is compatible with standard microcontroller technologies used in embedded systems.
The compact size of the 1.4 inch round resistive touch panel allows it to fit in small portable electronic devices, handheld instrumentation, wearables and other space-constrained systems. Its shape suits rotary-style dial and button interfaces often used in radio communications, medical devices, fitness trackers and IoT products. The touch panel comes with a protective hard coating and overlay to prevent physical damage that could affect touch sensitivity.
With its small, round form and analog resistive technology, the 1.4 inch touch panel delivers basic touch functionality for its size. While limited to single touch interactions, its 4-wire interface and average response time meet the needs of most compact devices with simplistic touch requirements. The touch panel provides an off-the-shelf solution for adding essential touch controls without requiring complex touch IC components. 
For product developers working with stringent size and space limitations, the 1.4 inch round resistive touch panel offers a touch interface option. Its compact, circular design suits products where a rounded touch area is preferred, or a circular display or interface is used. Although basic, this miniature touch panel enables the addition of touch in devices where no viable solution previously existed due to size restrictions.
The release of the 1.4 inch round resistive touch panel points to a market for more tailored touch components that suit non-traditional applications. As electronics become increasingly advanced yet miniaturized, demand rises for specialized touch interfaces compatible with unique form factors and shapes. This miniature touch panel represents progress toward more customized touch solutions that keep pace with rapid technological change in an era where one size no longer fits all. Its niche design highlights the potential for touch panels and components that meet the diverse range of specifications now seen in the embedded computing industry. Overall, this compact and rounded touch panel brings new possibilities for touch integration in the smallest of interfaces.
