Our Waterproof Touch Screen

PCAP is the most widely used and highly accepted touch sensor technology for human-machine interfaces. Our advanced projected capacitive touch design is engineered to minimize interference not only from water, but also from sweat and moisture caused by human interaction—a more challenging condition than ordinary waterproofing. 

 Normal PCAP touch is highly sensitive to water and sweat, which can create false touch signals or cause unresponsive behavior.
 Waterproof and sweat-resistant touch designs ensure accurate and stable operation under rain, condensation, washdowns, and high-humidity or high-interaction environments.
 Improved reliability extends device lifespan and reduces service interruptions, recalibration, and long-term maintenance costs.

Level	Condition	Description	Touch Performance
Level 1	Moisture	1: Make the TP surface dirty, breathe out on the View Area, virtual keypad zone, and line-drawing zone to see if any spot is reported/indicated;	No spot reported/indicated
Level 2	Water mist	1: To simulate drizzle rain by spraying water on the screen with a sprayer, use a single finger to draw lines randomly to see lines and spots;	Neither a broken line nor another spot is reported/indicated.
Level 3	Water Drips	1: Use a syringe to drop 1mL of water on the screen, and let it stay still for seconds before wiping it dry; then check if there is a spot caused in this process, if there is a residual spot after wiping the dry screen, and if there is no broken line beyond water zone. 2: Use a dropper to drop water on the screen to emulate rain.	No spot is reported/indicated after dropping water, And no residual spot is found after wiping. The water-free zone can be touched normally.
Level 4	Wet Finger	1: Dip the finger in water and use the finger to draw several lines on the screen before leveling the remaining water on the screen. Then use 2: Fingers to draw lines to see if there are broken lines, spots, mingled lines, etc.	Single-finger line drawing is normal; So is double-finger line drawing; No mingled, broken, or jump spots appear during line drawing.
Level 5	Pouring	Fannal’s waterproof DEMO with pouring water set.	There are no false touches, breaks, or jitters when drawing across pouring water.

 Water & Sweat-Resistant Touch Performance

 Flat, well-drained surface design: A system should have a flat surface design and be able to drain water off easily.
 Non-conductive border design: Eliminating conductive metal borders around the touch sensor prevents water from creating unintended grounding paths, which can otherwise be interpreted as real touch signals.
 Water-repellent (AF) glass treatment: Anti-fingerprint and water-repellent coatings reduce the contact area of water droplets, lowering interference signals and improving touch stability in wet and sweaty conditions.
