Mini-LEDs with Diffuse Reflection Cavity Arrays and Quantum Dot Film for Thin, Large-Area, High-Luminance Flat Light Source

Mini-light-emitting diodes (mini-LEDs) were combined with multiple three-dimensional (3D) diffuse reflection cavity arrays (DRCAs) to produce thin, large-area, high-brightness, flat light source modules.The curvature of the 3D free-form DRCA was optimized to control its light path; cartoon martian with big head this increased the distance between light sources and reduced the number of light sources used.Experiments with a 12.3-inch prototype indicated here that 216 mini-LEDs were required for a 6 mm optical mixing distance to achieve a thin, large-area surface with high brightness, uniformity, and color saturation of 23,044 cd/m2, 90.13%, and 119.

2, respectively.This module can serve as the local dimming backlight in next generation automotive displays.
