The requirements for the resolution and refresh rate of micro‐displays in virtual reality applications are getting higher and higher. High resolution and high refresh rates mean that massive amounts of data will be transmitted, which will undoubtedly put tremendous pressure on bandwidth. To solve this problem, this paper considers the application scenarios of digitally driven micro‐displays in the field of virtual reality and proposes a compression scheme based on bit‐plane. On the one hand, the traditional just noticeable difference model is improved. A just noticeable difference model suitable for bit‐plane and virtual reality applications is established. On the other hand, combined with the correlation of video data, white block skipping encoding is optimized to achieve bit‐plane compression. Based on the proposed scheme, this paper builds a digitally driven micro‐ display system based on bit‐plane compression with FPGA as the core. The effectiveness of the system is verified by lighting a digitally driven silicon‐based OLED micro‐display. The experimental results show that the digitally driven micro‐display system based on bit‐plane compression effectively improves the compression efficiency and reduces the transmission data. The display effect is good, which meets the needs of virtual reality applications.
