Home appliance panels are key components for operation and display on home appliances. Their design, materials and functions directly affect the user experience。

1. Common types

Touch screen panels：use capacitive or resistive technology and operate by touch (such as smart refrigerators and microwave ovens)。
Mechanical button panels： traditional physical buttons with clear feedback (such as washing machine knobs and old-fashioned rice cookers)。
LED/LCD display：displays operating status, time, temperature and other information (such as air conditioners and ovens).
Combined panels：touch + buttons + display (induction cookers and dishwashers)。

2. Mainstream materials

Glass panels： beautiful and easy to clean (common induction cookers and range hoods), but need to be impact-proof。
Plastic panels： low cost and light (mid- and low-end small appliances), may be easily scratched。
Metal panels：durable (commercial ovens, coffee machines), but may affect touch sensitivity。
Acrylic panels： good light transmittance (LED display area), weak anti-aging performance。

3. Core functions
Operation control：adjust temperature, mode, timing, etc。
Status display： real-time feedback of working status (such as progress, fault code)。
Intelligent interaction：Wi-Fi connection, voice control (smart home appliance panel)。
Safety protection： child lock, overheating reminder, waterproof design (such as washing machine panel)。

4. Purchase and maintenance recommendations
Key points for purchase:
Choose materials according to the usage scenario (kitchen appliances should be oil-proof first)。
Check sensitivity (touch panel needs to test reaction speed)。
Pay attention to waterproof level (such as bathroom appliances need IPX4 or above)。
Daily maintenance：
Avoid sharp objects from scratching the surface。
Turn off the power when cleaning, and wipe with a soft cloth dipped in neutral detergent。
Do not wipe the OLED screen with alcohol to prevent the coating from falling off。

5. Technology trends
Integrated design： hidden panel (such as refrigerator panel and cabinet integration)。
AI interaction：face recognition, gesture control (high-end models)。
Energy-saving display:：electronic ink screen (low power consumption, used for thermostat)。
Modular maintenance： panel components can be replaced separately to reduce after-sales costs。
