Modern LGPs incorporate tunable backlight units (TBUs) using liquid crystal (LC) arrays. These adjust luminance from 500-3,000 nits within 10ms, enabling HDR10+ compatibility. Power consumption drops by 60% during low-light scenes.

Ambient light sensors integrated into LGP edges enable auto-brightness control. These systems use machine learning to predict user preferences, reducing manual adjustments by 80%.

For IoT applications, NFC-enabled LGPs store device metadata in edge-lit patterns. A smartphone scan decodes 64-bit IDs via light modulation, useful for smart home authentication.

Flexible hybrid electronics (FHE) integrate LEDs directly onto LGP surfaces. These 10μm-thick circuits use silver nanowire traces, achieving 90% optical transparency. Applications include wearable displays with 12-hour battery life.
