High-Visibility 7 Segment LED Display for Cooking Timers
This high-visibility 7-segment LED display is engineered exclusively for cooking timers and kitchen appliance control panels, optimized to withstand extreme kitchen temperatures and deliver clear, error-free readouts of time, temperature, and cooking mode values. With a wide operating temperature range of +105°C to +120°C, it thrives in high-heat environments near oven cavities and heating elements—outperforming generic displays in durability and stability.
Featuring high luminous intensity, a big viewing angle, and multi-color options (red, blue, green, white, amber, orange), it ensures timer values are visible from any position on the kitchen counter, even through steam or ambient light. The display is IC-compatible, energy-efficient, and RoHS/REACH compliant, making it ideal for 24/7 operation in air fryers, toaster ovens, electric grills, and smart kitchen appliances.
