Abstract A mosaic‐form backlight system for high‐dynamic‐range display was introduced. The backlight unit consisting of a side‐emitting LED, a quadratic light guide, and a concentric prism sheet can form an isolated square super‐Gaussian distribution over the local area of liquid crystal panel. By means of our approach, high‐dynamic‐range display system can reduce the time required for processing compensated image signal.
