摘要

头戴式虚拟现实（Virtual Reality，VR）显示的持续升温推动微显示器不断向高分辨率、高刷新率的方向发展，然而微显示器有限的带宽难以承载虚拟世界下的海量图像数据，为了减少微显示器系统扫描成像过程中的时间冗余，提高数据传输效率和图像线性度，建立了一种伪随机扫描顺序的原子扫描模型。传统的微显示器是从第一个像素到最后一个像素连续顺序扫描的，原子扫描采用分子空间按位的扫描方法，将整个显示屏幕分成若干子空间，扫描时可以任意切换子空间。根据原子扫描模型设计了微显示器的原子扫描控制器，通过分辨率为1.6 k×3×1.6 k硅基OLED微显示器的验证，扫描达到了100%的传输效率和93.8%的线性度，相比于传统的十二子场扫描，时钟频率降低了约3.3倍。证明了原子扫描控制器的可行性，适用于超高清、高分辨率、海量数据的图像显示。

Abstract

The continuous warming of the virtual reality (VR) display pushes the microdisplay to the high resolution and high refresh rate. However

the limited bandwidth of the microdisplay is difficult to carry the massive image data in the virtual world. In order to reduce the time redundancy in the scan imaging process of the microdisplay system

improve the data transmission efficiency and image linearity

an atomic scan model of pseudo-random scan order is established. The atomic scan uses a molecular space-by-bit scan method. According to the atomic scan model

the atomic scan controller of the microdisplay is designed. Through the verification of the resolution of 1.6 k×3×1.6 k silicon-based OLED microdisplay

the scan achieves 100% transmission efficiency and 93.8% linearity

the clock frequency is reduced by about 3.3 times compared to the conventional twelve subfield scan. It proves the feasibility of the atomic scan controller and is suitable for image display of ultra-high definition

high resolution and massive data.
