QST SERIES – RESISTIVE TOUCHSCREEN
IMPROVED ENVIRONMENTAL PERFORMANCE
The QST Series is a premium 4-wire analog resistive touchscreen engineered for enhanced environmental durability and optical performance.
It utilizes a flexible printed circuit (FPC) made from high-resistance polyimide material, providing superior protection against humidity and environmental stress. This upgrade significantly improves reliability compared to standard general-purpose resistive models, resulting in longer service life and more stable performance in demanding applications.
PRODUCT OVERVIEW
Anti-Glare Optical Performance
The surface ITO film incorporates an integrated anti-glare treatment that reduces light reflection and improves visibility in high-brightness environments. For applications requiring maximum display clarity, the surface can be customized with a clear film option to enhance LCD image sharpness and transparency.
Functional Surface Coating
A specialized functional coating is applied to the touch surface to enhance usability and durability. Key benefits include:
Improved resistance to fingerprints and surface oils
Easier cleaning and maintenance
Suppression of Newton rings to enhance visual appearance
The anti-Newton ring treatment minimizes interference patterns that can occur due to air gaps and film deformation during actuation, preserving a clean and professional display finish.
Micro-Dot Spacer Technology
The QST Series incorporates high-density micro-dot spacers to form the insulation layer that supports the film structure. Compared to conventional designs, the reduced dot print size delivers:
Improved optical clarity
Lower actuation force
Reduced friction between layers
Enhanced durability and smooth tactile response
This results in a lighter, more precise touch experience while maintaining long-term mechanical stability.
WHY CHOOSE THE QST SERIES?
Anti-Fingerprint Coating
A dedicated fingerprint-resistant coating reduces oil adhesion and surface contamination caused by repeated finger contact. This makes fingerprints less visible and simplifies routine cleaning, improving long-term appearance and maintenance efficiency.
Anti-Newton Ring Suppression
Structural interference patterns that can occur between the resistive layer and LCD panel are minimized through specialized surface treatment, enhancing overall display quality.
High-Density, High-Precision Insulation Pattern
Advanced micro-dot spacer printing delivers exceptional pattern precision, reduced internal friction, and superior durability. The result is consistent tactile feedback with extended operational life.
