FST SERIES – RESISTIVE TOUCHSCREEN
5-WIRE RESISTIVE MODEL WITH ENHANCED RELIABILITY AND DURABILITY
The FST Series is an analog 5-wire resistive touchscreen platform engineered for superior stability, long service life, and dependable performance in demanding environments. It preserves the intuitive usability of traditional 4-wire systems while delivering significantly improved structural reliability and maintenance advantages.
PRODUCT OVERVIEW
Durable, Deterioration-Resistant Construction
In a 5-wire resistive architecture, the upper ITO film is used exclusively for voltage measurement, while the lower ITO layer responsible for position detection is deposited on the glass substrate. Because the detection layer resides on rigid glass rather than a flexible film, measurement accuracy is not affected by film flexure, mechanical stress, or changes in electrical resistance caused by repeated actuation. This structure provides:
• Greater mechanical durability
• Reduced performance drift over time
• Improved resistance to environmental and physical stress
Reliable and Accurate Detection
In conventional 4-wire systems, the upper ITO layer measures X coordinates and the lower ITO layer measures Y coordinates. If either layer degrades, detection accuracy is compromised. The 5-wire system eliminates this vulnerability. Voltage measurement occurs on the upper layer, while coordinate calculation is derived from the stable glass-based detection layer. As a result, the system maintains accurate input detection even if the flexible layer experiences wear. Benefits include:
• Higher long-term detection accuracy
• Greater operational stability
• Reduced risk of measurement failure
Anti-Glare Optical Performance
An anti-glare surface treatment is applied to the ITO film to suppress light reflection and improve visibility in high-brightness environments. For applications requiring maximum clarity, the surface can be customized with a clear film option to enhance LCD image sharpness.
WHY CHOOSE THE FST SERIES
Extended Keystroke Life
Compared to conventional 4-wire models rated at approximately 10 million actuations, the 5-wire FST Series exceeds 35 million touches. This represents more than 3.5 times the operational lifespan, delivering exceptional durability for a resistive touchscreen platform.
Improved Input Accuracy and Precision
The 5-wire architecture measures voltage on the upper ITO film and calculates XY coordinates through a more stable conversion method. This results in:
• More consistent coordinate accuracy
• Reduced signal instability
• Superior precision compared to 4-wire systems
