Frequent Asked Questions


What is the delivery timeline for your industrial touch screens?

Stock samples are dispatched within 3 days post-payment, while mass production takes around 15 workdays.


Does the presence of fingerprints or dirt impact the functionality of your touch screens?

No, our industrial touch screens are designed to operate flawlessly even with dirt, fingerprints, or liquid on their surface, ensuring uninterrupted performance of the interactive screen.


What chemicals are your HMI displays resistant to?

We use materials in our HMI panels that are highly resistant to industrial chemicals and gases. However, the level of resistance varies based on factors like concentration, exposure duration, and temperature. We provide a comprehensive chart detailing the chemical tolerance of each material used in our HMI products. For chemicals not listed or for additional queries, our engineering team is available to assist.


Are your HMI monitors suitable for outdoor environments?

Yes, our HMI displays are equipped for both indoor and outdoor use. When using outdoors, consider factors like direct sunlight affecting screen visibility and operating within the prescribed temperature range (0° to 50°C for operation, -20° to 60°C for storage). Our industrial touch screens, particularly those with a polyester cover sheet, might be sensitive to UV radiation. We offer alternative screens, like PCAP, better suited for outdoor conditions. Contact our sales team for more details.


What Are the Differences Between Low-Temperature Inks, High-Temperature Ceramic Inks, and UV-Resistant Inks?**

Low-temperature ink (standard product, requiring pre-tempering before silk screening, operating at 180-200°C), high-temperature ceramic ink (used outdoors, incompatible with AG process due to its process of silk screening before tempering, melting ink at approximately 800°C), and UV-resistant ink (also known as all-black ink, scratch-resistant and high-temperature resistant, similar process to low-temperature ink, prevents ink from falling off, with a minimum order quantity (MOQ) of about 200-300 pieces).


How Is UV Glue Utilized in Touchscreen Assembly?

Touchscreens use UV-resistant adhesive material for bonding, blocking over 99% UV and more than 75% IR, effectively preventing LCD black spots and extending product life. The adhesive used for bonding touchscreen cover glass and sensor is not very expensive.


Why Do Touchscreens Get Dirty or 'Moldy' Over Time?

The glass surface is smooth, so a protective film is applied to prevent contamination. If stored for a long time, moisture from the air can penetrate through the PE film to the glass, causing chemical reactions that lead to mold or dirt. For minor cases, cleaning with acids like white vinegar is used.


What Are the Differences in Sensor Production Techniques?

Silk screening is no longer used due to issues with functional failure and unstable electrical performance. Yellow light is more stable than laser, etching patterns (development) are better with yellow light, and the cost of yellow light molybdenum-aluminum-molybdenum is significantly higher than laser. The company currently uses laser technology for sensor production.


How Does Changing the Operating System Impact Capacitive Screens?

Changing to Windows 7 or higher generally has no impact, but switching to other systems may require loading drivers.


What Are the Transmittance and Hardness Limits for Touchscreens?

Transmittance is 85%-90%, and hardness is >6H. The default hardness for company cover plates is 7H, but higher hardness can be negotiated with suppliers based on customer requirements.
