GRAPHICS PROCESSOR SWITCHING BASED ON COUPLED DISPLAY DEVICES
In one example in accordance with the present disclosure, a computing device is described. The computing device includes a number of ports. Each port receives a connection to a display device. A first port is coupled to the first graphics processor which supports a number of display devices and a second graphics processor. The computing device also in-cludes a controller. The controller determines when a number of coupled display devices is greater than the number of display devices supported by the first graphics processor and switches the first port from being driven by the first graphics processor to be driven by the second graphics processor.
Ruggedized remote control display latency and loss of signal detection for harsh and safety-critical environments
Systems, methods, and apparatuses are disclosed for overcoming latency and loss of signal detection in remote control displays. An exemplary system includes a remote control, a host computing device, and one or more target systems communicatively coupled to each other over a wired and/or wireless network. One method includes receiving, by the remote control and from a host computing device, a first video frame captured by a target device, determining a first time corresponding to receipt of the first video frame, receiving, from the host computing device, a second video frame, determining a second time corresponding to receipt of the second video frame, comparing the time difference to a latency threshold, and causing an alert graphic element to be displayed indicating a latency in communication.
Display device and image display system having the same
An image display system includes a graphic processor which generates an image signal, a control signal, and a variable frequency signal; and a display device which displays an image at a frame frequency corresponding to the variable frequency signal from the graphic processor. The display device includes pixels connected to emission control lines, data lines, and scan lines; a controller which provides reference data including information on reference cycles, which are cycles in which an emission control start signal is output, to the graphic processor, outputs the emission control start signal based on the control signal, and adjusting an output timing of a scan start signal based on the variable frequency signal; an emission driver which supplies emission control signals to the emission control lines based on the emission control start signal; and a scan driver which supplies scan signals to the scan lines based on the scan start signal.
Display control device
A display control device is mounted on a vehicle and is configured to control display of information on a display device. The display control device includes an electronic control unit that determines whether there is information to be displayed on the display device, determines whether a predetermined first condition to determine that a driving operation by a user is not required is satisfied, determines whether a predetermined second condition to determine that the driving operation by the user is required is satisfied, controls the display device such that the display device displays the information when it is determined that there is information to be displayed on the display device and that the first condition is satisfied, and controls the display device such that the display device hides the information when it is determined that the second condition is satisfied.
DEVICE AND METHOD FOR FOVEATED RENDERING
A display driver includes image processing circuitry and drive circuitry. The image processing circuitry is configured to receive a foveal image, a full frame image, and coordinate data that specifies a position of the foveal image in the full frame image. The image processing circuitry is further configured to render a resulting image based on the full frame image independently of the foveal image in response to detection of a data error within the coordinate data. The drive circuitry is configured to drive a display panel based on the resulting image.
Video timing for display systems with variable refresh rates
A display system supports variable refresh rates that include a plurality of refresh rates. A source such as a graphics processing unit (GPU) provides frames to the display system at a selected one of the refresh rates. The refresh rates are factored into a corresponding plurality of prime factors. A plurality of numbers of lines per frame in frames provided at the plurality of refresh rates is determined based on one or more ratios of the plurality of refresh rates, the plurality of prime factors, and a line rate for providing frames to the display system at the plurality of refresh rates. The source then selectively provides frames to the display system at one refresh rate of the plurality of refresh rates using the same line rate regardless of which refresh rate is chosen. Furthermore, the number of lines per frame is an integer for frames provided at the refresh rates.
Augmenting Virtual Reality Content With Real World Content
Methods, devices, and computer programs for augmenting a virtual reality scene with real world content are provided. One example method includes an operation for obtaining sensor data from an HMD of a user to determine that a criteria is met to overlay one or more real world objects into the virtual reality scene to provide an augmented virtual reality scene. In certain examples, the criteria corresponds to predetermined indicators suggestive of disorientation of a user when wearing the HMD and being presented a virtual reality scene. In certain other examples, the one or more real world objects are selected based on their effectiveness at reorienting a disoriented user.
LASER PROJECTION DISPLAY DEVICE, AND METHOD FOR CONTROLLING LASER LIGHTSOURCE DRIVING UNIT USED FOR SAME
The laser projection display device includes: a photo-sensor for detecting the quantity of laser light generated by the laser light source; and an image processing unit for processing a drive signal on the basis of the quantity of light of the detected laser light and supplying the processed drive signal to a driving unit for the laser light source. Right after the dimming, the image processing unit supplies the drive signal to the driving unit for the laser light source on the basis of the quantity of light of the detected laser light within a second execution cycle shorter than a first execution cycle which is the execution cycle used during the normal operation.
Multi-thread graphics processing system
A graphics processing system comprises at least one memory device storing a plurality of pixel command threads and a plurality of vertex command threads.
