Particular embodiments described herein provide for an electronic device that includes a display and is configured enabling a low power refresh during a semi-active workload. The electronic device includes a display engine, where the display engine generates a video stream with a frame rate, a display, where the display includes an image viewable by a user and the image is refreshed at a first refresh rate, and a timing controller located in the display, where the timing control receives an indicator from the display engine and uses the indicator to determine that the first refresh rate can be lowered to a second refresh rate without the frame rate of the video stream from the display engine being changed. In an example, the indicator is frame with no image data at the start of the frame. In another example, the indicator is an implicit indictor sent by the display engine.

In an approach for dynamically adjusting parallel reality (PR) displays, a processor configures a viewing event. A processor receives data from data collecting devices located throughout a location of the viewing event. A processor classifies a crowd of the viewing event into at least two partitions using a learning-based neural network that ingests the data. A processor selects content to be displayed to each of the at least two partitions. A processor enables a PR display to simultaneously display the content to each of the at least two partitions.

An embodiment modular light-emitting diode (LED) display panel includes attachment points for use in attachment as part of a multi-panel modular LED display, a printed circuit board including a first side and an opposite second side, and a plastic casing attached to the opposite second side of the printed circuit board. A perimeter of the plastic casing is substantially rectangular and has a height and a width. The modular LED display panel further includes a display surface including a plurality of LEDs arranged as pixels and attached to the first side of the printed circuit board. The pixels are arranged in a rectangular array including at least fifty pixels. Each of the pixels of the rectangular array is spaced from each respective adjacent pixel of the rectangular array by a pitch. The pitch is a predetermined constant number. The pitch does not depend on the height and the width.

A control apparatus includes an acquiring unit configured to acquire a plurality of identification data indicating display performances regarding image qualities of a plurality of display apparatuses, and a generating unit configured to generate a first identification datum indicating a display performance with which all the display apparatuses are compatible using the plurality of identification data.

In accordance with some embodiments, an exemplary process for dynamically controlling the size of a display based on a moving of a visual object meeting a criterion in a computer-generated reality (CGR) environment is described.

A display panel, a display device including the display panel, and a personal immersive system using the display device includes a sample & holder that sequentially samples a data voltage sequentially outputted from a demultiplexer and then simultaneously output the data voltage to a plurality of data lines, and sub-pixels that sequentially charge the data voltage inputted from the sample & holder in response to a scan pulse.

A video play system, a video play device, and a video play method are provided. The video play system includes: a display module and a plurality of play modules electrically connected to the display module. The plurality of play modules individually decode and transcode a video source having first resolution to generate target video data, and simultaneously output the target video data generated themselves to the display module. The display module plays a video image having second resolution according to multiple channels of the target video data.

The present disclosure describes techniques for generating, maintaining, and operating a cooperative virtual reality (VR) environment across multiple computing devices. By utilizing these techniques, disparate users are able to work independently or in collaboration on projects within a single VR environment without the latency issues that plague prior VR environments. That is, unlike prior systems which are plagued with latency issues that interrupt the user's VR experience, the techniques described in the present disclosure allow for cooperative VR environments to be rendered in real time across large numbers of computing devices while enabling each computing device to provide a smooth user experience. Additionally, the techniques described herein distribute the data processing and analysis between the VR server and the individual computing devices rendering the cooperative VR environment.

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.

Various embodiments may provide an electronic device including: a housing; a first display configured to be slidable through the housing, wherein at least a portion of the first display is exposed to an outside through the housing, and a region of the first display, exposed to the outside, is capable of being changed based on sliding of the first display through the housing; a second display spaced a certain distance apart from the exposed at least portion of the first display and disposed to form a flat surface with the exposed at least portion of the first display; and at least one processor disposed in the housing, wherein the at least one processor is configured to display first content on the first display and second content on the second display. Various other embodiments are possible.
