  • Patent number: 11367376
    Abstract: The present application provides a display panel and a display device. The display panel includes a plurality of sub-pixels. Each sub-pixel includes a light-emitting unit and a drive switch electrically connected to a first electrode of the light-emitting unit. The light-emitting units in the multiple sub-pixels form a pixel array. Multiple light-emitting units in at least one pixel column of the pixel array correspond to sub-pixels of at least two colors. The drive switches in the multiple sub-pixels form a drive array. In the drive array, in drive columns correspondingly connected to the at least one pixel column, multiple drive switches in at least one drive column drive-control light-emitting units of the same color. Thus, the corresponding drive column can be connected to a peripheral drive circuit by using only one switch element.

  • Patent number: 11302288
    Abstract: The disclosed techniques use a display device, in conjunction with various optical sensors, e.g., an ambient light sensor or image sensors, to collect information about the ambient lighting conditions in the environment of the display device. Use of this information—and information regarding characteristics of the display device—can provide a more accurate determination of unintended light being added to light driven by the display device. A processor in communication with the display device may evaluate a saturation model based, at least in part, on the received information about the ambient lighting conditions and display device characteristics to determine unintended light. The determined unintended light may prompt adjustments to light driven by the display device, such that the displayed colors remain relatively independent of the current ambient conditions. These adjustments may be made smoothly over time, such that they are imperceptible to the viewer.

  • Patent number: 11282258
    Abstract: Image quality can be improved by rendering the image based on an importance map that indicates regions of the image that will benefit from more samples. Adaptive sampling determines a number of samples for each pixel of the image using a target sampling rate and the importance map for the image. The number of samples for each pixel needs to be a non-negative integer value, so the per-pixel sampling rates are quantized using per-pixel random values. The resulting quantized sampling rates provides a distribution of samples that closely matches the importance map. The per-pixel random values may vary over time so that the average of the distribution more closely matches the importance map.

  • Patent number: 11272039
    Abstract: A virtual reality network provides access to a number of virtual reality representations, each virtual reality representation representing a location in a virtual universe and defined by VR data stored on the network. The VR data can be in a simplified data format. A database stores the network address and the location in the universe of each virtual reality representation. A database server provides access to the database. The database server generates a list of locations in response to a location query from a visitor, and provides the network address of the virtual reality representation of a selected location. A visitor connects to the database server with a client host to visit the locations in the virtual universe.

  • Patent number: 11263476
    Abstract: The system and method are directed to a prototypical contrastive learning (PCL). The PCL explicitly encodes the hierarchical semantic structure of the dataset into the learned embedding space and prevents the network from exploiting low-level cues for solving the unsupervised learning task. The PCL includes prototypes as the latent variables to help find the maximum-likelihood estimation of the network parameters in an expectation-maximization framework. The PCL iteratively performs an E-step for finding prototypes with clustering and M-step for optimizing the network on a contrastive loss.

  • Patent number: 11244635
    Abstract: Visual safety is ensured when image switching takes place. When an image is switched by nonlinear reproduction, a display property is kept switched, during a transition display period, to a transition display property with a brightness level kept lower than a normal level, on the basis of pixel statistical information regarding the image. For example, an electro-optic conversion property is controlled to a transition property or the brightness level of a backlight is suppressed.
