This 4-inch 720*720 resolution circular TFT liquid crystal display features a small size with high pixel density (approximately 280 PPI, resulting in a clear and detailed image), a circular shape that is highly adaptable, and TFT technology that offers accurate color reproduction and fast response times. It has diverse applications in the fields of small appliances and medical devices.

1. The field of small household appliances: Enhancing operation interaction and visual experience

Kitchen small appliances: Present cooking parameters intuitively

Coffee machine / Health water dispenser: Display water temperature (such as 85℃ for coffee brewing, 100℃ for tea boiling), brewing time, remaining water volume, coffee concentration levels (low / medium / high), with a circular display that can simulate a "dashboard" visual effect, making the parameters easier to quickly read;
Air fryer / Mini oven: Display real-time temperature (such as 180℃ for chicken wings baking), countdown (20 minutes), cooking mode (bake / fry / dry), high resolution can clearly display small text icons (such as "preheating complete" prompt), avoiding visual blurriness;
Electric rice cooker / Electric pressure cooker: Display cooking mode (fine cooking / quick cooking / grain rice),保温 status, pressure value (such as 70kPa for high-pressure meat cooking), with a circular screen that can be embedded in the top or front of the device, forming a "visual center" with the operation buttons, enhancing the product's quality.

Household small appliances: Simplified function and status display

Humidifier / Dehumidifier: Show current humidity (e.g. 50% RH indoors), wind speed settings (low / medium / high), water tank level (full / medium / low). The circular display can be paired with dynamic icons (such as a water droplet animation indicating humidification is in progress), making the status more vivid;
Vacuum cleaner / Small cleaning equipment: Show battery level (e.g. 80%), cleaning mode (automatic / fixed points / along edges), fault indication (such as "roller brush clogged"), the small size is suitable for compact body structure, and high resolution ensures the fault text is clearly readable;
Smart desk lamp / Diffuser: Show brightness level (1-5 grades), color temperature (3000K warm light / 6000K cool light), remaining time for timer (such as 1 hour later turn off), the circular design can be integrated into the lamp base or top of the body, matching the "soft atmosphere" positioning.

2. Medical Device Field: Precisely Transmitting Monitoring Data and Operating Guidelines

Home portable medical devices: Assisting users in self-monitoring

Electronic blood pressure monitor: Displays systolic pressure (e.g. 120mmHg), diastolic pressure (80mmHg), and heart rate (70 beats per minute). The circular screen can simulate a "dial" visual effect, aligning with users' familiarity with traditional blood pressure monitors, and the high resolution ensures no blurriness and avoids misreading of the values;
Oxygen saturation monitor: Displays oxygen saturation (e.g. 98%) and pulse rate (65 beats per minute), along with a dynamic waveform graph (such as a pulse fluctuation curve). The circular display can focus on the core data, making it convenient for the elderly and patients to quickly view;
Blood glucose monitor: Displays blood glucose value (e.g. 5.6mmol/L), measurement time (e.g. 2024-05-20 08:30), and historical data call icon (e.g. "average value in the last 7 days"). The small size is suitable for handheld devices, and the high resolution ensures that decimal places (e.g. 5.68mmol/L) are clearly visible.

Medical small-scale medical devices: Assisting healthcare operations and patient observation

Desktop thermometer / forehead thermometer (medical version): Displays the actual body temperature (e.g. 36.5℃), temperature unit (℃/℉), measurement mode (forehead temperature / ear temperature). The circular screen can be embedded on the front of the device, facilitating healthcare professionals to quickly read and record;
Small electrocardiogram monitor (for outpatient use): Displays heart rate, simple electrocardiogram waveform (such as sinus rhythm curve). The circular image can focus on the key waveforms, assisting healthcare professionals in preliminarily judging whether the heart rate is stable;
Rehabilitation therapy equipment (such as low-frequency pulse device): Displays treatment level (1-10 grades), treatment duration (e.g. 20 minutes), mode selection (such as "shoulder and neck mode" "waist mode"), circular design can be combined with touch operation, allowing patients to intuitively understand the running status during treatment and enhancing their sense of security.
