Resistive vs. PCAP Technology Guide.

What is an Open Frame Monitor?

Open Frame: This type of monitor is designed without a front bezel, making it ideal for integration into a customer's own enclosure, kiosk, or cabinet. It typically features side mounting brackets for rear installation. Common applications include ATMs, gaming machines, and industrial control consoles.

Technology

Resistive vs. Projected Capacitive (PCAP)

Resistive (RTP): Pressure-activated technology. Works with any object (finger, gloved hand, stylus). Highly resistant to electrical noise, dust, and water drops. Best for harsh industrial environments.

Projected Capacitive (PCAP): Activated by electrical current (like a smartphone). Supports multi-touch gestures (zoom, pinch). Offers high optical clarity and a durable glass surface. Best for public kiosks, medical devices, and modern HMI.

FAQs

A. Touch Monitor Troubleshooting

A1. What are "Foldable Base" and "Vertical Base" options?
1. Foldable Base: Versatile stand that can be adjusted for table use, picture-frame style, or folded flat for wall hanging.
2. Vertical Base: A sturdy stand typical for POS systems, allowing for stable elevation angle adjustment.
A2. Why does my monitor show "Enter Sleeping Mode"?
The "Enter Sleeping Mode" message indicates the monitor is receiving no video signal. Please check if your VGA, DVI, or HDMI cable is securely connected. Try a different cable or computer to rule out signal source issues. If the problem persists, please contact AiM support.
A3. Do I need to install the touch driver?
While some AiM products are Plug & Play on Windows 7/8/10/11 (HID mode), we highly recommend installing the specific driver (eGalax/EETI) to ensure optimal performance, enable advanced calibration (Linearization), and support multiple monitor setups.
A4. Can I replace the touch panel glass by myself?
AiM does not recommend users replace the touch panel themselves. The process requires a cleanroom environment and specialized bonding techniques. Improper replacement may cause damage or dust contamination. Please contact us for professional repair services.
A5. What are the touch modes in Windows? (Mouse vs Digitizer)
1. HID-Mouse Mode: The cursor behaves like a standard mouse. Pen-down mimics a left-click. Supports single touch only.
2. HID-Digitizer Mode: Designed for Windows tablet features. Supports multi-touch, press-and-hold for right-click, and gesture recognition.
A6. How does the driver affect Windows 7/8/10/11?
1. With Driver Installed: Touch usually operates in Mouse Mode. It enables features like "Beep on Touch" and better multi-monitor mapping, but may limit native Windows multi-touch gestures.
2. Without Driver (HID): Windows uses its built-in Digitizer mode, enabling native multi-touch gestures but lacking advanced calibration options.
A7. Why does my app stop when I press and hold the screen?
This is likely due to the "Right Click" emulation. In the touch driver settings (Touch Package > Mouse Setting), disable "Auto Right Click" or "Right Click on Hold" to prevent this interruption.
A8. Touch function stopped working in Windows 10?
This can happen after Windows Updates. Try reinstalling the latest driver. In the driver utility, go to the "Hardware" tab and ensure the controller is detected. You may also try switching the mode: Touch Package > Advance > HID Mode > Select "Mouse-HID".

B. Resistive Touch Panel FAQs

B1. What is the Minimum Order Quantity (MOQ)?
MOQ requirements vary by panel size and customization level. Standard items may have lower MOQs. Please contact AiM Sales for details.
B2. What is the warranty period?
Standard Warranty: 1 year for 4-wire resistive panels; 3 years for 5-wire resistive panels (due to higher durability).
B3. Does changing the tail (FPC) location require new tooling?
Yes, changing the FPC tail exit location changes the sensor's internal circuitry, which is considered a new design requiring NRE (Non-Recurring Engineering) tooling fees.
B4. Are AiM products RoHS compliant?
Yes, all AiM Touch products are compliant with the RoHS (Restriction of Hazardous Substances) directive.
B5. Are AiM panels compatible with ELO or other brands?
Yes. We offer many standard resistive panels that are mechanically and electrically compatible with ELO and other major brands. Please provide the part number for cross-reference.
B6. Does AiM provide EMI-shielded touch panels?
Yes. We can offer Mesh or ITO coating solutions to meet specific EMI/EMC shielding requirements for military or medical applications.
B7. Why do "Newton Rings" (bulges) appear?
"Pillowing" or Newton Rings occur when the top and bottom layers of the resistive panel touch when they shouldn't, often due to air pressure changes or improper lamination/mounting tension.

C. Projected Capacitive (PCAP) FAQs

C1. What are the main applications for PCAP?
Due to its high clarity and durability, PCAP is ideal for Industrial HMI, Medical Devices, Outdoor Kiosks, and Public Transportation systems.
C2. How many touch points does AiM PCAP support?
Our standard PCAP solutions support up to 10 simultaneous touch points.
C3. What cover glass thickness do you support?
Standard thicknesses are 1.1mm, 1.8mm, and 2.8mm. With firmware tuning, we can support thick cover glass (up to 6mm-10mm) for vandal-proof applications.
C4. Does PCAP work with water on the surface?
Standard PCAP may experience "false touches" with water. However, AiM's advanced controllers feature "Water Rejection" firmware which ignores water droplets. Please note that while it prevents errors, full touch functionality may be limited until the water is wiped off.
C5. Can PCAP be operated with gloves?
Yes. We can tune the firmware to increase sensitivity, allowing operation with latex, nitrile, and even thick industrial cotton gloves. Please specify this requirement when ordering.

D. Touch Controller Board FAQs

D1. What resistive controllers do you offer?
We offer the AiM-RC-3xxx series. The "U" suffix (e.g., 3000U) indicates USB interface, while "C" (e.g., 3000C) supports both USB and RS-232 COM interfaces.
D2. What is the maximum cable length for USB/RS-232?
USB cables are typically reliable up to 5 meters. RS-232 cables can transmit reliable signals up to 15 meters.
D3. Why is the cursor inaccurate?
This usually means the screen needs calibration. Open the eGalaxTouch driver utility and run the "4-point calibration" or "Linearization" (9 or 25 points) for higher accuracy.
D4. Do you support Linux (ARM/MIPS) or Android?
Yes. For ARM/MIPS architectures running Linux or Android, we provide the kernel driver source code. You will need to compile the driver into your kernel. An NDA may be required to access the source code.

E. Projected Capacitive Controller FAQs

E1. Which IC does AiM use?
We primarily use EETI (eGalax) controller ICs, known for their industrial reliability and wide operating system support.
E2. What is COF?
COF stands for "Chip on Flex". The controller IC is mounted directly onto the FPC tail of the touch sensor, eliminating the need for a separate controller board and saving space in compact devices.
E3. Can controller parameters be adjusted?
Yes. Sensitivity, threshold, and noise filter parameters can be adjusted using the "Update Tool" utility. This allows us to fine-tune the screen for glove use or thick glass.
