Why Choose a Round TFT LCD Instead of a Standard Rectangular Display
A round TFT LCD display is the better choice when the product itself is built around a circular industrial design, radial menu layout, or rotary interaction method. In those cases, a rectangular display can leave unused corners, create layout compromise, and weaken visual consistency.
This 1.6 inch circular display module helps create a cleaner interface structure for compact devices while maintaining practical resolution, stable image output, and embedded integration value. For products designed around a knob, dial, round dashboard, or circular HMI concept, it offers a more natural display solution than a conventional square screen.
Why Choose This 1.6 Inch Round TFT LCD Display
This product combines the main qualities many engineering and OEM teams look for in a small circular display: true round structure, 400 × 400 resolution, ST77903 driver IC, QSPI interface support, and a compact size suitable for modern smart devices and embedded systems.
If your project requires a 1.6 inch round LCD module, a circular TFT display for embedded systems, or a round screen solution for smart control products, this module offers a practical balance of structure, compatibility, and application flexibility.
