How to Choose the Right AMOLED Display (1.38–8.0") for Your Application
Choosing the right AMOLED display is key to performance and reliability. From 1.38–8.0 inches, this guide covers seven factors to help you decide.

AMOLED needs differ by industry. Wearables (1.38–2.4") require compact size, low power, and outdoor readability. Industrial handhelds (3–5") focus on durability. Automotive dashboards (7–8") demand high brightness and wide temperature tolerance. Start with your exact use case.

Choose dimensions that match your product housing. Round and square modules suit watches, while rectangular panels suit handhelds and consoles. Always confirm bezel size, active area, and mechanical fit to avoid costly redesigns.

High pixel density ensures sharp graphics. Wearables need 300–450 PPI for clear icons, while larger panels often use FHD for clarity at longer viewing distances. Also consider color accuracy, contrast, and viewing angles.

Balance luminance with battery life. Small devices typically use 400–700 nits, while automotive displays exceed 800 nits for daylight visibility. Darker UIs save power since AMOLED pixels turn off individually when showing black.

Ensure the display matches your system’s processor. MIPI DSI is common for mid-size AMOLEDs, while SPI or RGB may be used for simpler devices. Check timing, driver IC support, and integration with touch panels.

For automotive and industrial use, ensure the panel supports extended temperatures, vibration resistance, and long lifetime. AMOLED suppliers often provide test data on humidity, burn-in, and environmental durability.
