Compact Transparent OLED for Creative Embedded Designs
The REX012856A is a 1.51-inch transparent OLED module that allows graphics and data to be displayed while still showing the background through the panel. This makes it ideal for products requiring data overlay, augmented optics, or semi‑see‑through interfaces. According to Raystar, the module achieves this through a specially designed transparent OLED panel structure.
Its 128×56 resolution provides sharp, clean rendering of icons, symbols, and alphanumeric content—all essential for compact instrumentation.
Key optical and mechanical characteristics include:
- Active Area: 35.052 × 15.324 mm
- Module Size: 42.04 × 27.22 × 1.2 mm
- Pixel Pitch: 0.274 × 0.274 mm
- Standard Emitting Color: Sky Blue (White, Green, Yellow, Blue, Red available on request)
Flexible Interface Options for Easy Integration
Raystar equips the module with the SSD1309 driver IC, one of the most established controllers in the OLED industry. This ensures broad compatibility with a wide range of MCUs and embedded platforms.
The display supports multiple interfaces, including:
- 6800 parallel
- 8080 parallel
- 4‑wire SPI
- I²C
These interface options make the display suitable for both ultra‑low‑pin-count designs and high‑speed communication requirements in industrial or portable devices.
Industrial Temperature Rating for Tough Environments
Transparent OLED may sound delicate—but Raystar designed this module for rugged operation. The operating temperature range is −40°C to +80°C, enabling deployment in harsh outdoor, automotive, or industrial environments where standard consumer displays fail.
The storage temperature extends even further to −40°C to +85°C, ensuring safe transportation and device longevity under extreme conditions.
Benefits of Transparent OLED Technology
Compared to conventional LCDs with backlights, transparent OLED offers several advantages:
- Self‑Emitting Pixels: Each pixel generates its own light – no backlight required. → Lower power consumption and ultra‑high contrast.
- Ultra‑Wide Viewing Angles: OLED maintains readability from extreme angles, ideal for handheld or dynamic‑angle device designs.
- Extra‑Thin Construction: COG structure results in a module thickness of only 1.2 mm, making it ideal for compact or portable instrumentation applications.
- Unique Visual Experience: The transparency creates visually appealing floating icons—useful for HUDs, optical sights, test equipment, smart tools, and AR-inspired interfaces.
Target Applications
Raystar’s 1.51-inch Transparent OLED is well suited for:
- Optical instruments such as scopes, sights, and measurement lenses
- Test & measurement devices requiring compact data overlays
- Wearable and handheld equipment
- Industrial HMI mini‑panels
- Medical devices
- Heads‑up displays (HUDs) and semi‑transparent user menus
- Display windows or product showcases for modern UI concepts
Transparent OLED enables compact but highly legible overlays without blocking the background—opening creative possibilities not achievable with LCDs.
Conclusion
The Raystar REX012856A 1.51-inch Transparent OLED Display delivers an impressive combination of clarity, transparency, ultra‑thin construction, wide operating temperatures, and easy MCU integration. For designers targeting innovative UI concepts or compact embedded visualization, this module provides a technology platform that is both robust and visually striking.
With its unique form factor and flexible interface support, it stands out as an excellent choice for next‑generation device designs across industrial, optical, wearable, and portable applications.
