QD-Mini LED 背光显示器边缘发蓝的机理与抑制研究

Mechanism and Suppression Studies of Blue Discoloration at the Edges of QD-Mini LED Backlit Displays

摘要

伴随着AI的发展，科技日益进步，电子产品的迭代越来越快，人们在日常工作中几乎离不开笔记本电脑，而电脑屏幕是人与电脑沟通的最重要的媒介，这使得消费者对显示屏的品质要求也越来越高。市场上常见的显示屏根据有无背光源分为OLED显示屏和LCD显示屏。LCD显示屏根据使用的背光源不同分为LED-LCD和QD Mini LED-LCD。QD Mini LED背光缘显示器凭借其独特的高亮度、高色域而深受消费者喜爱。即使在高亮的环境光下，也能清晰的看见显示器上的内容。然而QD Mini LED也存在着其劣势的一面——边缘发蓝，影响显示效果。本文基于实际问题出发，揭示发蓝机理，并提供相应的优化对策供背光源设计师们参考。

Abstract

With the advancement of AI and technological progress, electronic products are evolving at an accelerating pace. Laptops have become indispensable in daily work, with computer screens serving as the primary interface between users and devices—a fact that has driven rising consumer expectations for display quality. Market displays are broadly categorized into OLED and LCD types based on backlight technology, further subdivided into LED-LCD and QD Mini LED-LCD variants depending on backlight configurations. QD Mini LED displays have gained popularity due to their exceptional brightness and wide color gamut, ensuring clear visibility even under bright ambient lighting. However, these displays exhibit a notable drawback: blue edge artifacts that compromise visual clarity. This paper investigates the underlying mechanisms of this phenomenon and proposes optimization strategies for backlight designers.
