Abstract

The demand for extra-thin, large-area, and high-luminance flat-panel displays continues to grow, especially for portable displays such as gaming laptops and automotive displays. In this paper, we propose a design that includes a light guide layer with a microstructure above the mini-light-emitting diode light board. The light control microstructure of concave parabel-surface microlens arrays on a light-emitting surface increases the likelihood of total internal reflection occurring and improved the uniformity merit function. We used a 17 in prototype with quantum-dot and optical films to conduct our experiments, which revealed that the thickness of the module was only 1.98 mm. When the input power was 28.34 watts, the uniformity, average luminance, and CIE 1931 color space NTSC of the prototype reached 85%, 17,574 cd/m, and 105.37%, respectively. This module provided a flat light source that was extra thin and had high luminance and uniformity.

摘要

对超薄、大面积和高亮度平板显示器的需求持续增长，特别是对于诸如游戏笔记本电脑和汽车显示器等便携式显示器。在本文中，我们提出了一种设计，该设计在微型发光二极管灯板上方包括一个具有微结构的导光层。发光表面上的凹抛物面微透镜阵列的光控微结构增加了发生全内反射的可能性，并改善了均匀性品质因数。我们使用了一个带有量子点和光学膜的17英寸原型进行实验，结果表明该模块的厚度仅为1.98毫米。当输入功率为28.34瓦时，该原型的均匀性、平均亮度和CIE 1931色彩空间NTSC分别达到85%、17574 cd/m²和105.37%。该模块提供了一个超薄、具有高亮度和均匀性的平面光源。
