Standard Resistive Touch Screen
AMT resistive touch screens operate on a very simple principle that is reliable and consistent. Applications that prioritize command confirmation and overall safety often use resistive touch screens. AMT supplies resistive touch screens in sizes from 3.0" to 24" and hardware, software, resistive touch screen controllers, and drivers for operating systems from DOS to Windows 10 as well as Linux, Android, and QNX. Resistive touch screens can be constructed with 4-, 5-, or 8-wire circuitry.
Resistive Touch Panel Design
4-wire Resistive Touch Screen
4-Wire Resistive Touch Screen
4-wire resistive touch screens are suitable for small or medium sized products such as PDAs and hand-held devices. These panels utilize X+, X-, Y+ and Y- lead outs at the four edges of the screen. When contact is made, X/Y read-outs are then read by the controller and converted into the correct coordinates.
5-wire Resistive Touch Screen
5-Wire Resistive Touch Screen
In a 5-wire resistive touch screen, the top conductive layer is only responsible for voltage detection while voltage is applied alternately on the X and Y axes of the bottom conductive layer.
8-wire Resistive Touch Screen
8-Wire Resistive Touch Screen
8-wire resistive touch screens operate in the same fashion as 4-wire resistive touch screens, except an extra sensing wire is added to compensate for voltage falloff at the edges of the bus bar due to resistance (disrupting uniformity) as the size of the touchscreen increases. An 8-wire structure offers 4 additional screen read-outs, circuit protection, and is well suited for screens from 6" to 22".
Resistive Touch Panel Construction
Resistive Touch Screen-3-Layer Construction
3-Layer Resistive Touch Screen Construction
3-Layer resistive touch screens feature film-on-glass construction with a single circuit layer bonded to a scratch-resistant surface layer, over a layer of spacer adhesive, over a bottom layer of glass integrating a conductive coating.
Resistive Touch Screen-5-Layer Construction
5-Layer Resistive Touch Screen Construction
AMT's 5-layer resistive touch screen construction features two layers of ITO film bonded to acrylic or polycarbonate providing two layers of circuitry with an interposing spacer adhesive with the bottom ITO layer optically bonded to the backing panel.
AMT only manufactures 5-layer panels as OEM special orders based on individual customer needs and environmental requirements.
Resistive Touch Screen Surface Finish
AMT offers anti-glare and clear surface finishes for resistive touch screen. An antiglare finish is desirable in environments where glare from ambient lighting may interfere with LCD screen visibility and/or the likelihood of frequent scratching is high. AMT antiglare finish offers the highest antiglare index and provides the strongest resistance to environmental reflection. If ambient glare is not a concern, AMT’s clear finish provides the best possible image quality and superior visual results.
Resistive Touch Screen Tail
AMT provides a wide range of tail termination types for all configurations. AMT supplies 3 types of tail, allowing customers to choose the most suitable component for their needs.
Resistive Touch Screen Tail - Integral
- Same material as the top film.
- Sturdy construction.
Resistive Touch Screen Tail - HSC
- Maximum flexibility.
- Narrower bend radius available.
- Compatible with Matrix resistive touch screens.
Resistive Touch Screen Tail - FPC
- A Flexible Printed Circuit (FPC) refers to flexible electronics or flex circuits. It is produced by laminating copper strips between two PI/PET layers.
- Withstands more repeated connections.
- Narrowest available bend radius.
- Compatible with standard resistive and LR resistive touch screens.
AMT touch screens can be equipped with the following connector types, depending on application requirements:
- AMP (plain or with latch)
- AMPC (AMP compatible) with latch
- Berg (FCI)
- Resistive Touch Screen Connectors ZIF
- Resistive Touch Screen Connectors AMP
- Resistive Touch Screen Connectors AMPC with Latch
- Resistive Touch Screen Connectors BERG
