2.1 Inch Round IPS TFT LCD Display with 480x480 Resolution ST7701S Controller and SPI RGB Interface

• Size and resolution: Effective display diameter 53.28mm, resolution 480×480 pixels. The square pixel array perfectly fits the circular screen, with a clear and distortion-free picture.
• Display technology: Uses IPS wide-angle technology, with a viewing angle approaching full-angle (up, down, left, right 85°). The colors and contrast remain undistorted at any viewing angle.
• Driver and interface: Built-in ST7701S driver chip, integrating controller and driver functions. Supports 3-wire SPI and 18-bit RGB dual interfaces, capable of flexibly adapting to mainstream microcontrollers such as 51/AVR/STM32/Arduino.
• Color and brightness: Can display 262K colors. Typical brightness 300~550 cd/m². Clearly visible indoors, and the high-brightness version can cope with outdoor strong light environments.
• Electrical and environmental: Supply voltage 2.5V~3.3V, operating temperature -20℃~+70℃. Wide temperature stability, meeting industrial-grade standards.
• Structure: Module thickness approximately 2.2~2.3mm, ultra-thin design. Usually connected by 40Pin FPC, optional capacitive touch screen.

With its round design, high-definition picture quality and stable performance, it is widely used in the following fields:

• Smart wearable devices: Smart watches, bracelets, used as high-definition circular display panels to show time, health data and notifications.
• Smart Home and Household Appliances: Central control display screens for smart knob panels, coffee machines, microwave ovens, air conditioners, etc., presenting UI interfaces and parameters.
• Industrial Control and Instruments: Portable testers, industrial control equipment, analyzers, with compact and intuitive operation and data display interfaces.
• Vehicle electronics: Motorcycle gauges, car air conditioning control panels, in-car audio systems, featuring stylish circular interactive interfaces.
• Medical and consumer electronics: Small medical testing devices, Bluetooth earphone charging cases, smart speakers, etc., enhance the design and interaction experience of the products.
