Precautions for preventing scratches on the touch screen of industrial control computers

Essential Tips to Prevent Scratches on Industrial Control Computer Touchscreens

Industrial control computer (ICC) touchscreens are exposed to harsh environments, including dust, debris, and rough handling, which can lead to scratches. Scratches impair visibility, reduce touch sensitivity, and compromise the durability of the display. Protecting these screens is critical for maintaining operational efficiency and extending equipment lifespan. Below are practical strategies categorized by focus areas.

Proper Cleaning and Maintenance Practices

Using Microfiber Cloths for Wiping

Always clean ICC touchscreens with lint-free microfiber cloths to avoid introducing abrasive particles. Dampen the cloth slightly with distilled water or a mild, alcohol-free cleaning solution designed for electronics. Avoid paper towels, rags, or rough fabrics, which can scratch the surface.

A manufacturing plant in Germany reduced touchscreen scratches by 70% after switching to microfiber cloths, eliminating the use of shop towels that had previously caused micro-abrasions over time.

Gentle Circular Motion During Cleaning

Wipe the screen in small, circular motions to distribute pressure evenly and avoid concentrated friction on specific areas. Apply minimal force, as excessive pressure can weaken the protective coating or push debris into the screen’s surface.

An automotive assembly line operator noticed fewer scratches after training staff to use light, circular strokes instead of back-and-forth wiping, which had previously concentrated dirt at the edges of the display.

Avoiding Harsh Chemicals and Solvents

Never use ammonia-based cleaners, acetone, or abrasive compounds on ICC touchscreens. These chemicals can strip anti-reflective coatings or etch the glass surface. Stick to pH-neutral solutions approved for electronic displays.

A food processing facility prevented coating damage by replacing a generic glass cleaner with a specialized formula, preserving the touchscreen’s scratch resistance even after frequent cleaning cycles.

Protective Accessories and Environmental Controls

Installing Screen Protectors Designed for Industrial Use

Apply a high-quality, scratch-resistant screen protector made from tempered glass or polyethylene terephthalate (PET) film. Ensure the protector is compatible with the ICC’s touch technology (e.g., capacitive or resistive) to maintain functionality.

A power plant operator extended touchscreen lifespan by 3 years by installing industrial-grade screen protectors, which absorbed impacts from accidental tool drops and prevented direct contact with abrasive particles.

Using Enclosures with Sealed Bezels

House ICCs in enclosures with raised, sealed bezels to create a barrier between the screen and external contaminants. Choose enclosures rated for dust and water resistance (e.g., IP65 or higher) to minimize exposure to harsh elements.

A mining company reduced screen damage by 65% after upgrading to enclosures with rubberized bezels, which deflected debris and prevented scratches caused by vibrating equipment nearby.

Controlling Humidity and Temperature in Operating Areas

Maintain stable environmental conditions to prevent condensation or thermal expansion, which can weaken screen adhesives or cause micro-cracks. Use dehumidifiers in humid climates and heaters in cold environments to keep temperatures within the manufacturer’s recommended range.

A chemical processing plant avoided screen delamination by installing climate control systems in control rooms, stabilizing humidity levels below 60% and temperatures between 10°C and 30°C.

Operational Habits and User Training

Encouraging Clean Hands Before Touchscreen Use

Train operators to wash or sanitize their hands before interacting with ICC touchscreens to remove oils, dirt, or metal shavings that could scratch the surface. Provide hand sanitizer stations near control panels for convenience.

A semiconductor manufacturer cut scratch incidents by 50% after implementing a “clean hands first” policy, reducing the transfer of abrasive particles from workshop environments to sensitive displays.

Avoiding Sharp Objects Near Touchscreens

Prohibit the use of pens, styluses with hard tips, or tools near ICC touchscreens. Encourage finger-only interaction or provide soft-tipped styluses designed for capacitive screens if precise input is required.

An assembly line supervisor prevented scratches by replacing metal styluses with rubber-tipped alternatives, eliminating accidental gouges caused by operators using pens to navigate menus quickly.

Implementing Scheduled Inspections for Early Damage Detection

Conduct weekly visual inspections of ICC touchscreens to identify minor scratches or cracks before they worsen. Replace screen protectors or displays promptly if damage is detected to prevent further degradation.

A railway signaling operator caught early-stage scratches during routine checks, allowing timely replacement of screen protectors and avoiding costly touchscreen replacements due to deep gouges.

By adopting these measures, organizations can significantly reduce the risk of scratches on industrial control computer touchscreens. Proper cleaning, protective accessories, environmental controls, and user awareness work together to preserve screen integrity and ensure reliable operation in demanding industrial settings.
