The invention relates to panel self-refresh transmission of bulk data. The present disclosure is directed to systems and methods of transferring bulk data, such as OLED compensation mask data, generated by a source device to a sink device using a high-bandwidth embedded DisplayPort (eDP) connection contemporaneous with an ENABLED Panel Self-Refresh (PSR) mode. Upon ENABLING the PSR mode, the source control circuitry causes the source transmitter circuitry, the sink receiver circuitry, and the eDP high-bandwidth communication link to remain active rather than inactive. The source control circuitry generates one or more data transport units (DTUs) having a header portion that contains data indicative of the presence of a bulk data payload and the non-display status of the bulk data payload carried by the DTUs. 本公开涉及批量数据的面板自刷新传输。本公开针对的是与使能的面板自刷新(PSR)模式同时地利用高带宽嵌入式DisplayPort(eDP)连接将由信源设备生成的例如OLED补偿掩蔽数据之类的批量数据传送到信宿设备的系统和方法。在进入PSR模式后，信源控制电路使得信源发送器电路、信宿接收器电路和eDP高带宽通信链路保持活跃，而不是非活跃。信源控制电路生成一个或多个数据传送单元(DTU)，这些数据传送单元具有头
