Purpose-built for commercial mowing across steep slopes, inaccessible terrain, and large areas, the products feature exceptional climbing ability, 360-degree rotation, and remote control operation.
As the landscaping machinery industry rapidly evolves toward electrification and intelligence, KOHAM aims to integrate smart display screens into its mowers to provide users with more intuitive equipment status monitoring and control. Leveraging its technical expertise in industrial-grade outdoor display modules, Jictech has become a strategic partner for KOHAM’s display module solutions, providing customized display solutions for its remote-controlled mower product line to empower product intelligence upgrades.
Project Challenges and Solutions
Project Challenges
As outdoor operation equipment, lawn mowers operate in far more demanding environments than consumer electronics. Core challenges include:
Sunlight Readability – Screen must remain clearly readable under direct sunlight for real-time status and battery monitoring
Wide Temperature Range – From -20°C cold to +70°C heat, stable operation required across extremes
Dust/Water Protection & Durability – Grass clippings, dirt, dust, and moisture demand excellent protection and vibration resistance
Low Power Design – Purely battery-powered, display energy consumption must be minimized to preserve runtime
Compact Space Integration – Limited control panel space requires ultra-thin, compact design
Jictech's solutions
Jictech provides one-stop customization from design to mass production:
High-brightness outdoor TFT module – ≥800 nits, AG anti-glare, -20°C~+70°C wide temperature range
IP65 dust/water protection – Effective against dust and low-pressure water jets for harsh outdoor conditions
Vibration-resistant design – Passed full industrial reliability tests including vibration, shock, and salt spray
Ultra-low power solution – Optimized driver IC and backlight design, battery impact <5%
Ultra-thin compact structure – Perfectly fits the limited space of remote-controlled mower control panels
