How has the waterproof technology of touch screens evolved?

In Shenzhen, the capital of hardware innovation, we have witnessed the transition of touch screen waterproofing technology from simple glue sealing to molecular level protection. As a touchscreen manufacturer, we are honored to translate these technological breakthroughs into a competitive advantage for our customers' products. Today, let's delve into the stories behind those touch screen that 'drip water doesn't get in'.

• 1、 Three major innovations in waterproof materials

1. gel sealing replaces traditional rubber: our newly developed organosilicon gel remains elastic at -40 ℃, solving the problem of brittle sealing materials in cold environments, and has been successfully applied to Russian polar scientific research equipment.

2. Self repairing coating technology: When micro scratches appear on the screen, microcapsules in the coating release repair factors. This technology, derived from automotive paint surfaces, extends the waterproof life of medical disinfection screens by three times.

3. Breathable and impermeable film: Drawing on the ePTFE material used in outdoor sportswear, we have implanted a breathing membrane inside the screen to balance air pressure while blocking water molecules. This is the key to the ability of diving dashboards to operate at a depth of 30 meters.

• 2、 Customized solutions for special industries of touch screen waterproofing

Fishery processing equipment: In response to the high salt spray environment in the seafood processing workshop, we have developed a "corrosion-resistant and waterproof kit" - adding anodized aluminum frame and anti mold sealant on the basis of conventional processes.

On board touch screen: through simulation and analysis of the fluid impact of the wiper on the screen, the drainage channel angle and surface friction coefficient are optimized, so that the customized screen of Mercedes Benz heavy truck can still accurately touch in a 120 km/h rainstorm.

Children's education tablet: food grade silicone coating+flow hole design, even if children spill juice on the screen, the liquid will quickly drain from the bottom without seeping in.

• 3、 The 'puddles' we stepped on in those years

Do you remember the interactive screen project provided for Dubai Aquarium in 2018? The initial plan failed due to neglecting the slow penetration of the adhesive by water pressure. In the end, we solved the problem through the combination of "vacuum lamination+helium leak detection", which taught us to add pressure cycling testing to all underwater projects in the future.

Waterproof is not just a technical parameter, but also a reflection of product responsibility. When your end users can still operate the equipment smoothly on the deck with splashing waves or in the ICU with the smell of disinfectant, it is the best recognition of our touch screen craftsmanship
