Description

Model: PO120F390MS

The 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.

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.

FAQ

Where can I buy this display？

If you just need a few samples, it`s better to directly on our Aliexpress store, we are 5 stars feedback supplier with 100% Honesty. (The buy link is on the right of the product image)
For bulk orders, it`s better to contact us and get a better price. 

Different displays have different characteristics, just tell Gesight Display your application, and operating environment, Gesight Display will suggest a suitable display for you.

Gesight Display provide HDMI/Type-C controller board or individual demo kit to test.
The pictures of demo kit can be changed by yourself. 

Gesight Display will provide necessary specifications for most LCD/OLED on sale, including,
Display Datasheet
Display Drawing
IC Datasheet
Circuit schematic
For most electronics engineers, our specifications are enough to run the display, and we will provide some assistance.
But Gesight Display is not a school, if customers don`t know the basic knowledge to design circuit boards, we suggest using our controller board to drive the display.

First, you need to check whether this display has On-cell or In-cell touch panel, if has, it only needs to add a cover glass on it. If not, it needs an external touch panel.
(On-cell and In-cell are integrated PCAP touch panels on the display screen)
Because the shape of the cover glass depends on the design of the clients, to avoid infringement of appearance,  most of the developers need different customized touch panels.
Gesight Display can provide a customized touch screen with a low cost of tooling charge.

1. UPS/Fedex/DHL/TNT, the best choice for most clients, 3~7 days to arrive.
2. Aliexpress standard ship, this way is cheap and slow, usually take more than 10 days. Only for samples.
3. For Russian clients, EMS or Aliexpress shipment is better.
4. Any designated logistics are acceptable
 

Most display panels are from giant manufacturers such as BOE, Sharp, LG, EDO, AUO, etc. They have already tested with strict standards.
For OEM products from Panox Display factory, please check the quality test standards.   

The lifetime is different on different images, check the lifetime on datasheet to study it. 

If your Raspberry Pi can support the interface of the display panel, and you know how to program on Raspberry Pi, you can connect to our display.
If you don`t know or don`t want to write a display program on Raspberry Pi, it`s better to get an HDMI controller board from us, and Panox Display will send a config.txt file for reference.

  • Circuit schematic

Readable Under Sun

Compare to LCD, OLED has many advantages as follows:

Thin Like Paper:More than 50% thinner and lighter than LCD, creating an edgy form factor in style.

Green Power:Clock-mode standby can be up to 60 hours, much lower consumption compare to LCD displays.

"Wow" Effect:High contrast ratio and wide color gamut offer sharp and vivid image, and consistent display from any angle.

OLED Type Structures

        OLED driver as well as two divided into passive (PMOLED) active (AMOLED), which PMOLED simple structure, each pixel is represented by a separate cathode and anode control, no additional driver circuit, but too much control lines restrict its application of high-resolution large screen; AMOLED entire cathode surface electrode via a drive circuit driving the light emitting anode, significantly reducing the number of control lines, it has a low-power, high-resolution, fast response and other characteristics, AMOLED therefore gradually become the mainstream OLED display.
