    Screen-camera communication, a mode of visible light communication, can transmit additional information while enabling dynamic screen display. However, traditional camera-based schemes are limited by rolling shutter effects, which reduces transmission rates and reliability. To address this bottleneck, this paper proposes a fusion communication and display scheme based on single-pixel imaging. In this scheme, the transmitted information is encoded into a sequence of single-pixel measurements, subjected to an intensity transformation that preserves statistical characteristics, and then the display images are divided into multiple sub-frames according to the transformed modulation sequence. These sub-frames are sequentially displayed on an LED array, where human visual persistence integrates the high-speed switching sub-frames into continuous and coherent images. Simultaneously, a single-pixel detector captures the total intensity information of the sub-frames and decodes the transmitted information, achieving integration of communication and display. Experiments with a 32 × 32 LED array demonstrate error-free transmission at a viewing angle of 170° and a distance of 2.5 m, while preserving high-fidelity display quality. Additionally, single-pixel detection can still retrieve information even when the display is obscured by a scattering medium. This scheme presents a novel solution for integrating communication and display, thereby broadening of visible light communication.
