This 2.1-inch round TFT LCD display, featuring 480x480 resolution and capacitive touch, centers on "precision adaptation for irregular screens + flexible interaction via capacitive touch", suitable for smart watches, micro health monitors, industrial micro dashboards and other scenarios. The 480x480 square resolution enables full-area non-stretched display on the round screen—time scales and sports data on smart watches have a natural circular layout; heart rate waves and blood oxygen values on health monitors are presented in a circular interface, fitting visual habits; industrial micro dashboards can simulate traditional pointer dials, with intuitive display of parameters such as speed and pressure. The round shape perfectly adapts to the wrist curve of wearable devices and the compact structure of micro instruments, reducing edge space waste compared with square screens and enhancing the overall design of the device.
The capacitive touch function enhances the operating experience of micro devices: it supports single-point precise touch with a response delay of ≤0.06 seconds, allowing light touches to switch smart watch function interfaces and confirm health monitoring data, with smooth operation and no lag; the touch area covers the entire round screen, enabling dead-angle-free control and avoiding misoperation caused by narrow buttons of micro devices; the touch surface is covered with 2.5D curved scratch-resistant glass, which not only improves the hand comfort during wearing but also resists daily friction and slight collisions, with no scratches after long-term use; it has a sweat-resistant coating, so sweat adhesion during exercise does not affect touch sensitivity, adapting to multi-scenario use of wearable devices.
Display effect and compatibility are optimized: the screen brightness reaches 300nits, supporting 100-300nits manual adjustment, which is clearly visible under outdoor strong light and reduces brightness to avoid glare during night use; the color reproduction rate reaches 85%, making the dial patterns of smart watches and numerical markers of health monitors vivid; it can be directly connected to micro embedded chips (such as Nordic nRF52840, STM32L4 series), supporting I2C/SPI communication protocols, with no need for complex driver debugging, reducing hardware integration difficulty; low power consumption (operating power ≤35mW) adapts to the battery-powered needs of wearable devices, extending single-charge battery life to 7-10 days.
Durability adapts to micro scenarios: the overall thickness is only 2.8mm and weight is about 6g, with no obvious weight when embedded in watches or micro instruments; supports a wide temperature range of -10℃ to 60℃, adapting to outdoor low temperatures and normal human body temperatures; the waterproof level reaches IP65, so there is no need to worry about water damage during daily hand washing or rainy days, enhancing device practicality.
In summary, with 480x480 non-stretched display, precise capacitive touch, low-power and durable features, this 2.1-inch round display adapts to the irregular design needs of micro smart devices, providing an efficient interactive display solution for wearables, health monitoring and industrial micro dashboards.
