AMOLED Technology: How It Works

Active-Matrix Organic Light-Emitting Diode (AMOLED) is a self-emissive display technology where each pixel generates its own light. Unlike LCDs, no backlight is required, enabling true blacks, infinite contrast, and ultra-thin profiles.

Powered by LTPS or IGZO TFT backplanes, AMOLED delivers precise pixel control, sub-0.1ms response, and superior energy efficiency—making it ideal for high-performance applications in wearables, automotive, and industrial devices.

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.

1) Define Your Application

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.

2) Pick the Right Size & Shape

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.

3) Resolution & Visual Quality

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.

4) Brightness & Power Efficiency

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.

5) Interface & Compatibility

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.
