Abstract: 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.

Abstract: Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.

Abstract: In one example, a method for controlling a display with a digital signal includes detecting a binary value from a timing controller, the binary value corresponding to a portion of an image to be displayed. The method can also include determining a previous binary value from the timing controller and calculating a difference between the binary value from the timing controller and the previous binary value from the timing controller. Furthermore, the method can include generating an encoded signal based on the difference and transmitting the encoded signal to a display panel.
