When water gets on the screen, it starts “acting up.” The root cause lies in the principle of capacitive touch technology, which detects changes in the electric field caused by a finger approaching the screen. Both water and fingers are conductors. When water droplets land on the screen, they create false touch signals that fool the capacitive screen’s precise sensing mechanism, causing it to “see double” and generate “phantom touches.” Even after wiping the screen dry, residual moisture can still form tiny conductive circuits that interfere with the electric field, causing the touchscreen to malfunction temporarily.

Standard touchscreen chips are powerless in this situation and can only wait for the screen to dry completely.

Xinqihang’s large-screen touchscreen chip solves this problem at its core!

Rather than relying on screen protectors or software compensation, we’ve redesigned the signal acquisition and algorithms: more sensitive signal acquisition penetrates water films to detect real finger touches; intelligent waterproof algorithms automatically identify water droplet characteristics and filter out false touch points. Even when the screen is covered in water droplets, it can accurately distinguish between “water” and “fingers,” ensuring touch input remains stable and free from false triggers. There’s no need to wait after wiping the screen dry—it immediately returns to normal.

From outdoor vending machines to indoor meeting tablets, Xingqihang makes “erratic touch behavior caused by water” a thing of the past.
