Silicon-based organic light-emitting diode (OLED) microdisplays are widely used in the head-mounted devices. This article proposes a novel atomized scan method for the digital driving silicon-based OLED microdisplays. By eliminating the time redundancy in the digital driving, the proposed method generates the high transmission efficiency, high lighting efficiency, high grayscale efficiency, and good linearity compared with the traditional pulsewidth modulation (PWM) scan methods. Four scan characteristics of the high-efficiency scan sequence are analyzed. The high efficient atomized scan can be obtained by implanting the low grayscale scan into the high grayscale scan. A 1.6 k $\times1.6$ k full color silicon-based OLED microdisplay, together with the hardware driving platform, is designed and implemented to verify the proposed atomized scan method. By measuring the brightness values of 256 gray levels, the atomized scan method with the blank operation can achieve high scan efficiency with the low clock frequency (57.6 MHz).

用于高清晰度硅基 OLED 微显示器的雾化扫描方法

硅基有机发光二极管（OLED）微显示器广泛用于头戴式设备。本文提出了一种用于数字驱动硅基OLED微显示器的新型雾化扫描方法。通过消除数字驱动中的时间冗余，与传统的脉宽调制（PWM）扫描方法相比，该方法产生了高传输效率、高照明效率、高灰度效率和良好的线性度。分析了高效扫描序列的四个扫描特性。将低灰阶扫描植入到高灰阶扫描中，可以获得高效的雾化扫描。1.6 k $\times1.6 $ k 全彩硅基OLED微显示器，连同硬件驱动平台，被设计和实施以验证所提出的原子化扫描方法。通过测量256个灰度级的亮度值，空白操作的雾化扫描方法可以在低时钟频率（57.6 MHz）下实现高扫描效率。
