Input Interface
OLED (Organic Light Emitting Diode) Displays emit light at the pixel level, delivering true black, high contrast, ultra‑fast response, and thin, flexible form factors. This makes them ideal for premium UX, compact devices, and transparent showcase effects. Design trade‑offs include burn‑in risk management, peak brightness in strong ambient light, and supply chain planning.
Glass substrate, mature supply, excellent image quality. Common in handhelds, HMI panels, and embedded modules.
Polyimide substrates allow curves and folds for wearables and wrapped UX. Observe minimum bend radius and stack stress.
See‑through visuals for retail showcases and AR‑style overlays. Plan ambient lighting and background contrast carefully.
Viewing distance and PPI targets; avoid over‑spec that wastes power.
Ambient light vs required peak luminance; consider AR glass.
Motion vs static UI to manage differential aging.
MIPI DSI / eDP / SPI per SoC/MCU; verify lanes, timings, drivers.
Power rails and efficiency at target APL; IR drop validation.
Touch + display coexistence (noise/EMI) planning.
Rigid vs flexible substrate; minimum bend radius.
Cover lens: glass/PMMA with AR/AG/AF coatings as needed.
Optical bonding (OCA/LOCA) for contrast and ruggedness.
| Parameter | Typical Range | Engineering Notes |
|---|---|---|
| Resolution & Size | 0.42"–15.6", 128×64 to 3840×2160 | Match PPI to viewing distance to balance clarity and power. |
| Brightness | 300–1000+ cd/m² | Account for APL derating; AR glass improves readability. |
| Color Gamut | sRGB to DCI‑P3 98%+ | Calibrate D65 white; consider metamerism under retail lighting. |
| Lifetime (L50) | 30k–100k hours | Content and brightness drive aging; use UI mitigation. |
| Interfaces | MIPI DSI / eDP / SPI | Confirm SoC/MCU support, PHY lanes, and driver maturity. |
| Operating Temp | -20°C to +70°C (typ.) | Thermal path and coatings impact performance and life. |
| Application Area | Key Features and Use Cases |
|---|---|
| Wearables | Curved dials, always-on displays, and ultra-low power consumption for extended wearable use |
| Industrial HMI | High-legibility user interfaces with rugged cover lenses for harsh industrial environments |
| Retail Signage | Transparent overlays and premium display showcases to enhance visual appeal and customer engagement |
| Medical & Instruments | High-contrast data visualization at close viewing distances for precise, reliable readings |
Select based on UX priority, ambient light, and lifecycle TCO.
| Aspect | OLED | Mini‑LED (LCD) | Standard LCD |
|---|---|---|---|
| Black/Contrast | Per‑pixel off; best blacks | Local dimming; possible halo | Backlight; lowest contrast |
| Thickness | Thinnest (no backlight) | Thicker (zones + backlight) | Moderate (backlight) |
| Peak Brightness | Good; sunlight challenging | Very high possible | High typical |
| Burn‑in Risk | Needs mitigation | None | None |
| Cost | Higher | Higher‑mid | Lower |
Burn-in occurs when organic materials degrade unevenly due to prolonged display of static images. Prevention includes using auto-dimming, screen timeout, pixel shifting, logo dimming, and avoiding high brightness for static content.
Standard OLEDs struggle in direct sunlight due to limited peak brightness. However, some models feature higher nits output and anti-reflective coatings. For full outdoor use, consider Mini-LED or specialized high-brightness OLED variants.
OLED lifetime is typically rated at 30,000 to 100,000 hours to L50 (half brightness). Lifespan depends on usage patterns, brightness levels, and operating temperature. Blue pixels degrade faster, so white balance may shift over time.
Yes — OLEDs are ideal for AOD due to low power consumption when showing dark themes or small icons. To reduce burn-in risk, use dynamic positioning, low brightness, and limit active pixels.
AMOLED (Active Matrix OLED) uses a TFT backplane for fast refresh and large resolutions, ideal for smartphones and wearables. PMOLED (Passive Matrix OLED) drives rows/columns directly, suited for smaller, simpler displays with lower cost.
Yes — most OLED modules integrate capacitive (PCAP) or resistive touch layers. Flexible OLEDs often pair with curved touch sensors for seamless wearable and automotive designs.
