Abstract: In an exemplary variable rate display interface, a high-speed reverse data transfer is enabled over plural lanes of a display serial interface (DSI) bus during blanking periods. Further increases in bandwidth of each high-speed reverse data transfer may be achieved by increasing DSI clock speed during the blanking periods. Since a display relies on a host clock to send reverse data, the frequency of the reverse data is increased, which effectively increases the bandwidth of reverse channel lanes. By increasing the reverse bandwidth over existing pins in the DSI bus, more data may be transferred to the host, including raw touch/stylus data rather than processed data. The raw data may then be processed by the host's relatively powerful processors. By shifting the processing to the host, the need for a powerful touch screen controller (TSC) and/or a powerful touch display driver integrated circuit (TDDI) may be avoided.

Abstract: An organic light emitting diode display device includes a display module having a display panel and a panel driver; a host system separated from the display module with a timing controller to control the panel driver; and an interface device between the host system and the display module. The interface device includes a cable between the host system and the display module, a transmission module to compress display data from the timing controller in an active period of each frame without compressing sensing data and recovery data supplied in a blank period of the frame and to transmit the compressed display data, the non-compressed sensing data and recovery data via the cable, and a reception module to decompress the compressed data transmitted via the cable, to supply the decompressed data to the panel driver, and to supply the non-compressed data to the panel driver without data processing.

Abstract: A system, method and apparatus for implementing a wireless point-to-point interface that securely and robustly delivers digital content from a generalized content source to a generalized content sink. The system, method and apparatus performs in a manner that is sufficiently secure and robust to serve as a replacement for the delivery of HDMI content over cable. The system, method and apparatus is also applicable to the delivery of other types of content traditionally delivered over cable, including but not limited to Digital Video Interface (DVI) content, composite video (CVSB) content, S-video content, RGB video content, YUV video content, and/or various types of audio content.
