A method of configuring a display device interface (DDI) detects a trigger signal, generated by a display device. If the trigger signal is associated with a power on event, a full configuration of the DDI is performed, including loading display device capability information provided by the display device into DDI configuration registers and setting one or more DDI configuration parameters accordingly. If the trigger signal is associated with resume event, rather than a power on event, a modified fast link resume operation may be performed to route the trigger signal to a controller configured to explicitly write display device capability information to the appropriate DDI configuration registers before setting the corresponding DDI configuration parameter accordingly. The DDI may include a re-timer, between the DDI source and sink, configured to snoop the explicit write transaction such that the re-timer configuration is also updated.

Disclosed herein are techniques to provide notification of the type and/or attributes of frame updates. A platform can notify a panel of further frame updates, whether the frame update is a full frame update or a partial frame update and attributes of the frame update. The platform can notify the panel of information about the frame update during a vertical blanking interval by asserting a command or signaling the panel using selected symbols during the vertical blanking interval.

The present disclosure relates to a signal processing device and an image display apparatus including the same. The signal processing device includes: an input interface to receive an image signal; a first image processor to generate first image frame data based on the image signal; a second image processor including a scaler to generate second image frame data scaled down in comparison with the first image frame data; and an output interface to output the first image frame data and the second image frame data, wherein the scaler generates at least one super pixel or super block and outputs the scaled down second image frame data including the super pixel or the super block. Accordingly, it is possible to generate the scaled down second image frame data with reduced error as compared to the first image frame data.

Methods and systems are disclosed for an upstream facing port implementation for DisplayPort link-training tunable PHY repeaters (LTTPRs). The device includes an upstream facing port to interface with an external DisplayPort source device and a downstream facing port to interface with an external DisplayPort sink device and the upstream facing port. The upstream facing port is configured to perform operations including receiving a main link data stream from an external transmitting display device, generating an outbound main link data stream, and providing the outbound main link data stream for transmitting by the external device. The device is also configured for receiving an updated main link data stream corresponding to the outbound main link data stream and sending the updated main link data stream to the downstream facing port to be transmitted to a receiving display device.

Methods, systems and devices for displaying video content on large, high resolution video walls, which may comprise a mesh network of an array of display tiles with redundant network switching, in which a virtual, unlimited pixel canvas is created in a video controller memory to facilitate packetizing and addressing of video content packets for delivery to the video wall through a packet-switched network. Embodiments disclosed are particularly well-suited for use with video walls employing LED tiles.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.

Technologies for power efficient display synchronization are disclosed. A compute device may be connected to two display devices. The compute device may send image data to be displayed on each of the display devices in a burst mode, sending the image data in less time than the time between frames. The compute device may then enter a low-power state prior to sending the next image to the display devices. Before sending the next image to the display devices, the compute device may send a synchronization signal, which the display devices may use to synchronize the timing of displaying images between the two display devices.

A time code display system comprising: a video receiver configured for receiving a plurality of non-homologous video signals; a time code parser connected with the video receiver and configured for extracting time code data of each video frame from each video signal; a write controller and a buffer, the write controller being connected with the video receiver and the time code parser; a synchronous clock component configured for generating a local clock signal according to a channel associated clock signal of any video signal; and a read controller and a display, the read controller being connected with the synchronous clock component and the buffer and configured for reading out the video frame of each video signal and the time code data corresponding to the video frame from the buffer at the same time, according to the local clock signal.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment.
