Analysis of touchscreen and Display Waterproof Design Requirements
A sound waterproof design not only prevents water intrusion and malfunctions, but also significantly extends product lifespan and reduces maintenance costs.
1. The Importance of Waterproofing
touchscreen and display devices have strict waterproofing requirements in the following scenarios:Outdoor terminals: Self-service terminals, parking meters, and information kiosks
Industrial control: Automated production lines and process monitoring
Medical equipment: Frequent disinfection and cleaning required
Maritime and automotive systems: Long-term exposure to rain, moisture, and salt spray
Wearable and handheld devices: Frequent contact with sweat, rain, and cleaning agents
Potential risks (if waterproofing is insufficient):
2. Mainstream Waterproofing Standards
IP Ratings (International Protection Ratings)
IP65 – Dustproof and withstands low-pressure water jets from any direction
IP67 – Dustproof and withstands immersion in 1 meter of water for 30 minutes
IP68 – Dustproof and withstands long-term pressurized submersion
IP69K – High-pressure, high-temperature water washdown resistance, suitable for the food and pharmaceutical industries.
NEMA rating (North American standard)
Similar to IP rating, but with additional assessments for corrosion resistance and sealant durability.
3. Key Elements of Waterproof Design
A. Touch Technology SelectionPCAP (Projected Capacitive Touch) – The preferred choice for waterproofing, capable of operating through protective glass or plastic, supports multi-touch, and features a fully sealed design.
Resistive Touch – Poor water resistance and susceptible to false touches due to water pressure.
Infrared/Surface Acoustic Wave (SAW) – Sensitive to water droplets and unsuitable for humid environments.
B. Optical Bonding
Using optically clear adhesive (OCA/OCR) to directly bond the touch sensor to the LCD eliminates air gaps, prevents moisture intrusion, and improves visibility in hot and humid environments.
C. Sealing Structure
Silicone/Foam Sealing Ring
O-Ring Waterproof Interface
Overmolded Bezel for Outdoor Devices
Fully Laminated Glass or Polycarbonate Cover
D. Materials and Surface Treatment
Cover: Chemically strengthened glass or waterproof polycarbonate
Coating:
Hydrophobic/Oleophobic Coating – Repels water droplets and oil stains
Anti-Glare Coating – Improves outdoor visibility
Waterproof Adhesive: For module lamination and sealing
4. Waterproof Verification and Testing
Water Immersion Test
Simulated Rain and Spray Test
High-Pressure Washdown (IP69K)
Salt Spray Corrosion Test (Maritime/Industrial)
High-Temperature Cycling and Anti-Condensation Testing
5. Design Challenges
Maintaining High Touch Sensitivity While WetPreventing False Touches Caused by Water Droplets
Preventing Condensation Between Display Layers
Balancing Waterproofing and Heat Dissipation Requirements
6. Best Design Practices
Select PCAP touchscreens that support gloves and water-resistant operation algorithmsAdopt a full lamination and IP67/IP68 sealing solution
Use a breathable waterproof membrane to balance internal and external air pressure and prevent water ingress
Integrate with an outdoor, high-brightness, condensation-resistant LCD to ensure readability in extreme environments
Conclusion
The design of a high-performance waterproof touchscreen display is a comprehensive engineering effort involving touch technology, sealing processes, material science, and standard compliance.Utilizing PCAP and optical full lamination technology, a touchscreen display solution remains stable and reliable even in the most demanding environments, meeting the comprehensive needs of demanding industrial, medical, maritime, and outdoor applications.
