摘要： Driving a display of an input-display device includes generating, during a first display frame, a first touch sensing waveform to be applied to a touch screen of the display, and generating, during a second display frame, a second touch sensing waveform to be applied to the touch screen. The first touch sensing waveform generates on the display a first touch-to-display noise pattern of touch-to-display noise artifacts. The second touch sensing waveform generates on the display a second touch-to-display noise pattern of touch-to-display noise artifacts. The second touch-to-display noise pattern mitigates the first touch-to-display noise pattern.

摘要： Systems and method for streaming video content include downscaling video content using a downscaling model to generate downscaled video content and downloading the downscaled video content as a video stream and corresponding upscaling model to a client device. The system converts received video frames to a video memory format comprising channels having the same memory allocation size, each subsequent channel arranged in an adjacent memory location, for input to the downscaling model. The client device upscales the video stream using the received upscaling model for display by the client device in real-time. A training system trains the downscaling model to generate the downscaled video content, based on associated metadata identifying a type of video content. The downscaled video content and associated upscaling models are stored for access by an edge server, which downloads upscaling models to a client device to select an upscaling model.

摘要： This disclosure provides methods, devices, and systems for data compression and decompression. The present implementations more specifically relate to entropy encoding and decoding techniques for keeping a state variable within upper and lower bounds using a noniterative process. The entropy encoding uses a fixed state threshold to determine a number of bits to remove and removes the bits from a current state prior to encoding a symbol with the current state. The entropy decoding decodes encoded data in a bitstream based on a current state to obtain the symbol and a new state and determines a number of bits to read from the bitstream and to add to the new state to update the current state.

摘要： A display device includes a display panel, a backlight device, a drive circuit, and a backlight control circuit. The backlight device includes a plurality of light sources configured to illuminate the display panel. The drive circuit is configured to update the display panel based on an input image. The backlight control circuit is configured to apply a filter to a target part of the input image to generate a filtered image part. The target part of the input image is displayed in a corresponding region of the display panel illuminated by a target light source of the plurality of light sources. The backlight control circuit is further configured to control a luminance level of the target light source based on a maximum pixel luminance level of the filtered image part and a local average picture level (APL) of the filtered image part.

摘要： An apparatus for remote processing of raw image data receives the raw image data from a camera, such as a security camera. The apparatus includes a detection module to detect portions of the image data that contain possible regions of interest. Information indicating the portions that contain the possible regions of interest is then used during a compression process so that the portions that contain the possible regions of interest are compressed using one or more compression algorithms to facilitate further analysis and the remainder are treated differently. The compressed image data is then transmitted to a central system for decompression and further analysis. In some cases, the detection system may detect possible regions of interest which appear to be faces, but without performing full facial recognition. These parts of the image data are then compressed in such a way as to maintain as much facial detail as possible, so as to facilitate the facial recognition when it is carried out at the central server. The detection may be performed on the raw image data or may be performed as part of the compression process after a transformation of the raw image data has been carried out.

摘要： A display driver includes a bump array with a staggered bump arrangement, a data compensation circuit, and driver circuitry. The data compensation circuit processes input pixel data for a pixel of a display panel to generate compensated pixel data. The driver circuitry generates a data voltage based on the compensated pixel data and output the data voltage to the pixel via a bump of the bump array. The processing of the input pixel data is based on a location of the bump in the bump array.

摘要： A display driver includes image processing circuitry and drive circuitry. The image processing circuitry is configured to generate first voltage data for a first pixel in a first screen area of a display panel using a first gamma parameter. The image processing circuitry is further configured to generate second voltage data for a second pixel in a second screen area of the display panel using a second gamma parameter set. The image processing circuitry is further configured to determine an interpolated gamma parameter set for a third pixel in a connection area of the display panel through interpolation between the first gamma parameter set and the second gamma parameter set. The connection area is disposed between the first screen area and the second screen area. The image processing circuitry is further configured to generate third voltage data for the third pixel using the interpolated gamma parameter set.
