This application provides an electronic device, to reduce a probability that a screen stalling phenomenon. A timing control unit sends one first pulse of a tearing effect signal every a first preset time T1. The timing control unit sends S second pulses of the tearing effect signal when a transceiver unit does not receive an N.sup.th frame of display data within a preset time. The processing unit receives the N.sup.th frame of display data in the (N+1).sup.th frame, and controls, based on the N.sup.th frame of display data, the display to display an N.sup.th frame of image.

Ray tracing systems have computation units (“RACs”) adapted to perform ray tracing operations (e.g. intersection testing). There are multiple RACs. A centralized packet unit controls the allocation and testing of rays by the RACs. This allows RACs to be implemented without Content Addressable Memories (CAMs) which are expensive to implement, but the functionality of CAMs can still be achieved by implemented them in the centralized controller.

The present disclosure relates to a chip booting control method, a chip, a display panel, and an electronic apparatus. The method is applied to a control circuit of a chip, and the chip further includes a buffer. The method includes: reading first booting information from the buffer in response to a chip triggering non-power-down reset, the first booting information being used to boot the chip; determining whether the first booting information satisfies a first preset condition; and booting the chip according to the first booting information in response to the first booting information satisfying the first preset condition.

A graphics pipeline includes a cache having cache lines that are configured to store data used to process frames in a graphics pipeline. The graphics pipeline is implemented using a processor that processes frames for the graphics pipeline using data stored in the cache. The processor processes a first frame and writes back a dirty cache line from the cache to a memory concurrently with processing of the first frame. The dirty cache line is retained in the cache and marked as clean subsequent to being written back to the memory. In some cases, the processor generates a hint that indicates a priority for writing back the dirty cache line based on a read command occupancy at a system memory controller.

Systems, methods, and non-transitory media are provided for dynamically switching frame rates without changing a display refresh rate. An example method can include receiving, from a display device associated with a computing device, a set of control signals indicating a display refresh rate implemented by the display device; adjusting a frame rate associated with application data from one or more applications executed on the computing device; synchronizing, based on the set of control signals, the adjusted frame rate with two or more display refresh cycles, each display refresh cycle being based on the display refresh rate; providing, to the display device, a first frame at the adjusted frame rate, the first frame being generated based on the application data; and displaying the first frame at the display device implementing the display refresh rate.

Video or graphics, received by a render engine within a graphics processing unit, may be segmented into a region of interest such as foreground and a region of less interest such as background. In other embodiments, an object of interest may be segmented from the rest of the depiction in a case of a video game or graphics processing workload. Each of the segmented portions of a frame may themselves make up a separate surface which is sent separately from the render engine to the display engine of a graphics processing unit. In one embodiment, the display engine combines the two surfaces and sends them over a display link to a display panel. The display controller in the display panel displays the combined frame. The combined frame is stored in a buffer and refreshed periodically. In accordance with another embodiment, video or graphics may be segmented by a render engine into regions of interest or objects of interest and objects not of interest and again each of the separate regions or objects may be transferred to the display engine as a separate surface. Then the display engine may transfer the separate surfaces to a display controller of a display panel over a display link. At the display panel, a separate frame buffer may be used for each of the separate surfaces.

An embodiment of an electronic processing system may include an application processor, persistent storage media communicatively coupled to the application processor, a graphics subsystem communicatively coupled to the application processor, an object space adjuster communicatively coupled to the graphics subsystem to adjust an object space parameter based on a screen space parameter, and a sample adjuster communicatively coupled to the graphics subsystem to adjust a sample parameter of the graphics subsystem based on a detected condition. Other embodiments are disclosed and claimed.

A gallery view or a virtual space view is provided in an online meeting user interface associated with a videoconferencing system. The gallery view or virtual space view displays video feeds of meeting participants on their respective participant computers. The video feeds are camera-captured views of each of the meeting participants. The videoconferencing system receives an electronic request from one or more meeting participants via the meeting participant's respective participant computer to either display a mirrored view of the video feed of the meeting participant to all meeting participants in the online meeting, or display an unmirrored view of the video feed of the meeting participant to all meeting participants in the online meeting. A video processor associated with the videoconferencing system creates the respective mirrored or unmirrored view of the video feed of each of the meeting participants whose participant computer sent the electronic request. The videoconferencing system then generates instructions for a gallery view or virtual space view in the online meeting user interface using the mirrored or unmirrored view of the video feeds created by the video processor, and transmits instructions to display the gallery view or virtual space view to all meeting participants on their respective participant computers.

Disclosed is a display method of a display panel. The display panel includes two display screens arranged opposite to each other, and the display method of the display panel includes: acquiring a liquid crystal response duration of each display screen upon receiving image information to be displayed; taking a display screen having a shorter liquid crystal response duration as a first display screen, and taking a display screen having a longer liquid crystal response duration as a second display screen; and driving the second display screen to display, and delaying to drive the first display screen to display. A display device and a display panel are also disclosed. The display panel of the present application has a good display effect.

A display controlling method for a broadcast receiving apparatus allowed to receive IP simultaneous broadcasting of a 4K broadcasting service via a communication transmission line, in which simultaneous broadcasting of the 4K broadcasting service and a 2K broadcasting service is executed by a broadcasting wave, is configured to: receive and demodulate the 4K broadcasting service, and display a broadcasting program of the 4K broadcasting service; and select and execute one display switching process of first and second display switching processes in accordance with priority order in a case where a defect occurs in reception, demodulation, or display of the 4K broadcasting service, the 2K broadcasting service being received and demodulated to display a broadcasting program of the 2K broadcasting service in the first display switching process, the IP simultaneous broadcasting being received and demodulated to display a program of the IP simultaneous broadcasting in the second display switching process.
