The 1.28 Inch TFT LCD Module is a circular-shaped, low-power display solution designed for smart wearables, smart homes, and consumer electronics. Its compact circular design and high pixel density (PPI) deliver delicate visuals, making it a top choice for devices that require both aesthetic appeal and functional performance. | |||||||||
Aesthetic Circular Form: The 1.28-inch circular screen fits the rounded design aesthetics of wearable devices (such as smartwatches), enhancing the product’s visual appeal compared to traditional square screens.
High PPI & Clarity: With a 240×240 resolution and a 32.4mm×32.4mm circular AA area, it achieves a pixel density of 188PPI. This ensures text edges are free of jaggedness and chart data is clearly distinguishable—ideal for displaying health metrics like step counts and heart rate.
IPS Full-View & Brightness: Equipped with 350nit brightness and a 1100:1 contrast ratio, it performs well in both indoor and outdoor scenarios. IPS technology eliminates color cast from any angle, ensuring users can read information accurately in different postures.
Low Power & Flexible Interfaces: The 2.5V~3.3V low-power design matches the battery power supply requirements of wearable devices. It also offers SPI/RGB dual interfaces, which can adapt to different main control chip solutions, reducing development costs and improving solution flexibility.

According to the "2024 Small Display Module Industry White Paper", the global shipment of smart wristbands and watches reached 580 million units in 2023. Among these, products equipped with 1–1.5 inch circular screens accounted for over 40%, with an annual growth rate of 25%.
Smart Home Field: In 2023, the market size of small control panels (less than 2 inches) in the smart home sector exceeded 3 billion yuan. Due to their design advantages, circular screens saw an 18% annual increase in penetration rate.
Portable Medical Equipment Field: The demand for 1–1.5 inch display modules in small health monitoring devices grows at an annual rate of 30%. Over 60% of elderly-friendly devices prefer circular screens, as they are easier to read and operate.
Third-party organization Counterpoint predicts that by 2025, the global market size of 1–1.5 inch circular display modules will exceed $5 billion, with smart wearables and portable healthcare serving as the core growth drivers.
After production, the circular screen undergoes testing of brightness uniformity, color accuracy, and viewing angle using BM-7 professional optical equipment. This ensures consistent visual effects across the entire circular display area.
The module is tested in extreme environments (ranging from -20°C to 65°C) and high humidity (80% RH) to simulate real-world wearable use conditions. Low-power testing is also conducted to confirm it meets the battery life requirements of wearable devices.
