| IP65 | First digit 6: dust-tight. No dust ingress is permitted. Second digit 5: protected against water jets from any direction. | TFT LCD Sunlight-readable LCD Touchscreen LCD | Indoor and outdoor locations exposed to dust, rain, cleaning spray, and low-pressure water jets. | High-brightness LED backlight, anti-glare cover glass, sealed front bezel, gasketed enclosure, and optical bonding where required. | Factory HMIs, outdoor control panels, digital signage, test equipment, kiosks, and industrial monitoring terminals. | IP65 does not certify protection against immersion. Check the complete assembly, cable glands, connectors, buttons, and touch-panel seals. |
| IP67 | First digit 6: dust-tight. No dust ingress is permitted. Second digit 7: protected against temporary immersion in water, normally up to 1 meter for up to 30 minutes under standardized test conditions. | Rugged TFT LCD Outdoor LCD module Optically bonded LCD | Mobile equipment, field instruments, marine-adjacent environments, washdown areas, and equipment that may be accidentally submerged. | Sealed aluminum or polymer housing, waterproof connectors, reinforced cover glass, anti-condensation design, and sunlight-readable backlight options. | Vehicle displays, portable instruments, agricultural equipment, outdoor automation, inspection systems, and compact marine controls. | The test assumes specified conditions. Repeated, pressurized, hot-water, or long-duration immersion may require additional verification beyond IP67. |
| IP68 | First digit 6: dust-tight. No dust ingress is permitted. Second digit 8: protected against continuous immersion in water under conditions specified by the manufacturer or certification body. | Fully sealed TFT LCD Rugged touchscreen LCD Embedded LCD assembly | Equipment exposed to extended immersion, severe weather, heavy splash, or demanding outdoor and marine conditions. | Fully sealed housing, bonded display stack, waterproof cable exits, corrosion-resistant materials, pressure-tested enclosure, and moisture-control measures. | Marine instrumentation, subsea monitoring equipment, remote outdoor controls, harsh-environment vehicles, and specialized industrial systems. | IP68 has no single universal immersion depth or duration. Confirm the exact certified depth, test duration, temperature, pressure, connector configuration, and service conditions. |
| IP65 | Dust-tight and protected against water jets, making it suitable for routine exposure to rain and surface cleaning. | Transmissive LCD Industrial monitor Projected-capacitive touch LCD | Controlled industrial areas and outdoor installations where continuous immersion is not expected. | Matte anti-reflective glass, wide-temperature LCD panel, front-access maintenance, and sealed mounting frame. | Production lines, energy equipment, building controls, parking systems, and outdoor information terminals. | Transmissive LCDs require a backlight and may need high luminance for direct sunlight. Specify viewing angle, operating temperature, and condensation resistance. |
| IP67 | Dust-tight and resistant to temporary water immersion when the complete display assembly is correctly sealed. | Sunlight-readable LCD Wide-temperature TFT Glove-touch LCD | Outdoor and vehicle applications with vibration, dust, rain, and occasional immersion risk. | High-luminance LED backlight, optical bonding, impact-resistant lens, anti-glove touch interface, and vibration-resistant mounting. | Construction machinery, material-handling vehicles, fleet terminals, outdoor measurement devices, and field service equipment. | Ask for test evidence covering the final enclosure, not only the bare LCD panel. Thermal expansion, shock, vibration, and cable bending can affect sealing performance. |
| IP68 | Dust-tight and suitable for continuous immersion only within the specific limits declared for the tested product. | Rugged bonded TFT Sealed touch display Custom LCD module | Severe industrial, marine, remote, and outdoor applications requiring the highest commonly used enclosure protection level in this comparison. | Low-reflection cover lens, sealed touch sensor, conformal protection for electronics, corrosion-resistant enclosure, and custom pressure-rated sealing. | Marine control systems, remote monitoring, process equipment, harsh-environment robotics, and specialist transportation systems. | Confirm whether the rating applies during operation, whether the touchscreen remains functional when wet, and whether field servicing preserves the original rating. |
