Model: PO120F390MSThe 1.20-inch Circular AMOLED Display is built for compact smartwatch and wearable interfaces where sharp UI, vivid color, and low power matter. With a 390 × 390 resolution and 16.7M colors, it delivers clean icons, crisp text, and smooth dial graphics in a space-efficient round form factor.Designed for stable system integration, this module supports MIPI (command mode) SPI connectivity and provides a 350 nits (typ.) luminance for clear indoor-to-bright-room visibility. It offers wide viewing angles of 80° in all directions (CR > 1600) and achieves a fine 326 PPI for detailed rendering on small screens. With an Active Area 30.42 × 30.42 mm and an ultra-slim 33.22 × 34.72 × 0.66 mm outline, it fits slim device designs while keeping the display footprint premium. The module uses the AUO W022 ASIC and connects via a 24-pin FPC with a recommended BM28 series connector. Typical power consumption is 128.7 mW under full white at 350 nits, supporting efficient always-on style UIs. Application Smart Watch UI | Wearable Devices | Round Display Terminals | Embedded HMI | Test & Evaluation Fixtures Customized Options FPC  | Touch Panel | Cover Glass | Controller Board | Brightness Demo Kit for Quick Evaluation & Color Test The PO120F390MS demo kit is built to make first-time bring-up simple: connect the display module, load test patterns, and verify performance in minutes. As shown in the image, the screen is running a color bar test, which is commonly used to quickly check color accuracy, channel balance, and uniformity across the full circular active area—before you move on to real UI content.With a demo kit workflow, you can validate key points early, such as clean RGB transitions, stable image output during continuous refresh, and consistent brightness across different patterns. It’s a practical setup for engineering evaluation, incoming inspection, and fast proof-of-concept builds—so you can focus on firmware and product integration instead of building a driver environment from scratch. Protective Tray Packaging for Safe Handling & Shipping To keep the PO120F390MS modules safe during transport and assembly, the displays are packed in a dedicated tray cushioning foam format that separates each unit and prevents surface contact. This packaging helps protect the round AMOLED active area and the FPC from scratches, bending, or pressure marks—especially important for ultra-thin modules used in wearable designs.The tray layout also improves production efficiency: modules are neatly positioned and easy to pick, making incoming inspection, sampling tests, and line-side feeding smoother and faster. For projects that require reliable logistics and consistent quality, this packaging method supports stable delivery and reduces the risk of handling-related damage. Dynamic Content Switching Demo for UI Validation This animated demo highlights the PO120F390MS in a real switching scenario, where the circular AMOLED continuously changes images and UI content to verify display stability in motion. Rapid content transitions help confirm clean edge rendering on the round active area, smooth picture changes, and consistent color presentation—useful when you’re tuning watch faces, widgets, notifications, or compact HMI screens.During bring-up and evaluation, this type of demo is especially practical for checking frame-to-frame consistency (no obvious flicker or tearing in normal viewing), fine-detail clarity (icons/text edges), and overall visual uniformity when the screen is driven continuously. It’s a straightforward way to validate real-world UI behavior before committing to full system integration.
