This 2.1-inch round SPI IPS TFT LCD display, featuring 480x480 resolution, centers on "low-power integration of SPI interface + scenario adaptation of round screen", suitable for micro smart wearables (e.g., children's GPS watches), portable environmental monitors, industrial micro status indicators and other scenarios. The SPI interface, as a core advantage, only requires 4-6 pins for data transmission, reducing wiring space by 50% compared with traditional interfaces, perfectly adapting to the compact internal structure of children's watches and micro monitors; with a transmission rate of 10Mbps, it can synchronize watch GPS data and monitor temperature-humidity information in real time, and its operating power consumption is only 28mW. Equipped with a micro lithium battery, it can achieve 12-15 days of battery life, solving the battery life shortcoming of micro devices.
IPS technology and 480x480 resolution enhance display practicality: no color distortion at 178° full angles, so parents can clearly view positioning information from the side when the child wears the watch, and multiple positions can check the status of industrial indicators without visual deviation; the 480x480 resolution achieves 190PPI pixel density on the round screen, with sharp and clear environmental data curves of monitors and cartoon dial details of watches. The round screen also avoids information waste at the corners of square screens, allowing core content (e.g., positioning coordinates, concentration values) to be displayed in the center, improving reading efficiency.
Detailed design adapts to the needs of micro devices: the screen supports 100-300nits manual brightness adjustment, with low brightness for children's watches at night to avoid glare and high brightness for outdoor monitoring to resist reflection; the surface is covered with a 1.8D scratch-resistant PET film, balancing thinness and durability, resisting daily bumps of children's watches and friction of monitors in field use; with an overall thickness of 2.5mm and weight of 5.5g, it has no obvious bulk after being embedded in watches or monitors, fitting wearing and handheld usage habits.
Compatibility and stability are optimized: compatible with 8-bit/16-bit MCUs (e.g., STM32F103, PIC18F series), no additional level conversion module is needed, reducing hardware development difficulty; it has basic anti-interference ability, and can still stably display data under slight electromagnetic environment in industrial workshops and wireless signal interference of wearable devices, avoiding screen flicker or data confusion.
In summary, with low-power and easy integration of SPI, IPS wide viewing angle and 480x480 HD, this 2.1-inch round SPI display adapts to micro wearables and industrial devices, providing an efficient display solution for scenarios requiring compact structure and long battery life.
