Background and Challenge
In recent years, kitchen equipment has seen increased multifunctionality and digital recipe settings, driving higher demand for displays. However, introducing displays capable of withstanding the harsh, unique kitchen environment presented challenges.
Risk of Failure Due to High Temperature and Humidity
Steam and heat from equipment like steam convection ovens easily cause condensation on displays and deterioration of electronic components.
Harsh Operating Conditions
Reliable operation is required while handling wet hands, greasy hands, or wearing thick rubber gloves during cooking.
Chemical Resistance During Cleaning
Concerns exist that surface panels may become cloudy or degrade when wiped with strong cleaning agents or alcohol.
Visibility in the Kitchen
Cooking status (temperature, remaining time) must be clearly visible from a distance or at an angle.
Reasons for Selection
Industrial-grade wide temperature/high humidity compatibility
TFT operates from -20℃ to 70℃, VFD from -40℃ to 85℃, handling extreme temperature fluctuations. Moisture-resistant conformal coating on circuit boards is available for high humidity environments.
High-sensitivity touch panel
Proprietary sensitivity control technology minimizes malfunctions from water droplets or oil, enabling smooth operation even through rubber gloves.
Superior chemical resistance and robust flat structure
A thick cover glass with excellent chemical resistance can be installed, enhancing strength and preventing degradation during maintenance like alcohol cleaning.
Wide viewing angle and clear display performance
The use of VFD provides excellent visibility. Switching the TFT from resistive to capacitive touch enables a clear, blur-free display, allowing instant confirmation of settings and warnings in busy kitchen environments.
