Compatible Touchscreen Controller
Product Detail
-
![High-Spec Model]()
-
Improved Rnvironmental
High-Spec ModelThe QST series is a high-spec model of the 4-wire analog resistive touchscreen series. It uses a flexible printed circuit board (FPC) made of polyimide material, which is highly resistant to humidity. This improves the environmental resistance of general-purpose products, making them easier to use and longer lasting.
-
![Anti-glare film that suppresses glare]()
-
Anti-glare film
that suppresses glareThe surface ITO film uses an anti-glare film that suppresses light reflection. Customization allows you to change to a clear film that clearly shows the liquid crystal image.
-
![Functional film coating makes it easier to use]()
-
Functional film coating
makes it easier to useThe coating is applied to the surface of the product to make it more resistant to fingerprints and easier to wipe off. The coating also has a special treatment that prevents Newton rings from appearing, making the product look better.
-
![More user-friendly with microdot spacer]()
-
More user-friendly
with microdot spacerThe use of micro-dot spacers makes the print on the dots forming the insulator that supports the film smaller than before, making it easier to see and lighter to press.
Why choose the QST SERIES?
-
![Anti-fingerprint coating to suppress fingerprints]()
-
Anti-fingerprint coating
to suppress fingerprintsBy applying a fingerprint-resistant coating on a film that is easily soiled with oil when pressed with a finger, the film becomes less susceptible to oil and fingerprints are less noticeable. This makes it easier to wipe off the film, which improves the daily maintenance efficiency.
-
![Anti-Newton Ring Coating]()
-
Anti-Newton Ring Coating
The air gap between the resistive touchscreen and the liquid crystal, and the Newton rings (interference stripes) that may occur structurally due to the relationship between the deformation of the film when pressed, are suppressed to improve the appearance.
-
![High-Density, High-Precision, & Durable Insulation Pattern]()
-
High-Density, High-Precision,
& Durable Insulation PatternMicro-dot spacers are used to form high-density and high-precision dot printing patterns. This reduces friction between the film and objects, and realizes excellent durability and smooth press feeling.
