Abstract

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; this increased the distance between light sources and reduced the number of light sources used. Experiments with a 12.3-inch prototype indicated 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/m, 90.13%, and 119.2, respectively. This module can serve as the local dimming backlight in next generation automotive displays.

摘要

微型发光二极管（mini-LED）与多个三维（3D）漫反射腔阵列（DRCA）相结合，以生产出薄型、大面积、高亮度的平面光源模块。对3D自由形式DRCA的曲率进行了优化，以控制其光路；这增加了光源之间的距离，并减少了所使用的光源数量。对一个12.3英寸原型进行的实验表明，对于6毫米的光学混合距离，需要216个微型发光二极管，以实现一个具有高亮度、均匀性和色彩饱和度的薄型大面积表面，其亮度、均匀性和色彩饱和度分别为23,044 cd/m、90.13%和119.2。该模块可作为下一代汽车显示器中的局部调光背光源。
