摘要： A system and method for denoising a sequence of images while maintaining a consistent appearance among images displayed consecutively in the sequence. A machine learning system maps a first input image in the sequence of images to a first output image based on a neural network algorithm and determines a first network loss based on differences between the first output image and a ground truth image. The system further maps a second input image in the sequence of images to a second output image based on the neural network algorithm and determines a second network loss based on differences between the second output image and the ground truth image. The system determines a consistency loss based on differences between the first output image and the second output image and updates the neural network algorithm based on the first network loss, the second network loss, and the consistency loss.

摘要： An input device configured for multi-factor authentication. The input device includes a plurality of sensor electrodes, one or more light sources, and an authentication component. The plurality of sensor electrodes is configured for capacitive sensing in a sensing region of the input device. The one or more light sources are configured to illuminate at least a portion of the sensing region of the input device. The authentication component is configured to receive a first authentication input via a first authentication device, determine whether the first authentication input matches a first credential of an authorized user, and selectively activate the one or more light sources based at least in part on whether the first authentication input matches the first credential of an authorized user.

摘要： 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.

摘要： An input-display device includes a display screen on a display substrate and capacitive sensing electrodes for capacitive sensing in a sensing region of the display screen. The input-display device also includes a touch and display driver integration (TDDI) circuit on the display substrate, the TDDI circuit including a source driver circuit driving a subset of display pixels of the display screen based on a processed image signal, and an analog frontend for the capacitive sensing, interfacing with the capacitive sensing electrodes to obtain touch signals. The input-display device also includes an image processing circuit generating the processed image signal based on a received image signal and a display parameter, a touch processing circuit generating a touch output signal by processing the touch signals based on instructions of a touch firmware, and a memory physically separate from the display substrate, the memory storing the display parameter and the touch firmware.

摘要： A display driver that drives a display panel comprises storage circuitry, color addition processing circuitry, and drive circuitry. The storage circuitry stores F subpixel data acquired from color coordinate data indicating color coordinates of a displayed color in a predetermined color space displayed on the display panel when an R subpixel, a G subpixel, and a B subpixel in each of a plurality of pixels of the display panel are driven with drive signals corresponding to a minimum grayscale value and an F subpixel in each of the plurality of pixels which displays an additional color other than a primary color R, a primary color G, and a primary color B is driven with a drive signal corresponding to a maximum grayscale value. The color addition processing circuitry generates output FRGB data from input RGB data, in response to the F subpixel data stored in the storage circuitry.

摘要： A processing system for an input device includes an in-phase and quadrature (I/Q) receiver module including a first and second charge integrators, and first and second demodulator modules. The I/Q receiver module alternates integration of a resulting signal, received from a receiver electrode of the input device, between the first and the second charge integrators in four consecutive quarter cycles, to obtain four consecutive integration results. The four consecutive quarter cycles coincide with one cycle of a local oscillator signal for the first and second demodulator modules. The I/Q receiver module further alternates demodulation of the four consecutive integration results between the first and second demodulator modules. The first demodulator module performs an in-phase demodulation to produce an in-phase component of a sensing signal associated with the first resulting signal, and the second demodulator module performs a quadrature demodulation to produce a quadrature component of the sensing signal.

摘要： A method of detecting shift of a rotatable interface is disclosed. The rotatable interface has a fixed base with a conductive region on a bottom surface, the fixed base attached to a display screen of an input device. The method includes providing, during a first time period, a reference signal to first and second sets of electrodes of the input device that are each capacitively coupled to the conductive region. The method further includes, during a second time period, providing the reference signal to the first set of electrodes, providing a sensing signal to the second set of electrodes, and receiving, during the second time period, a resulting signal on the second set of electrodes. The method still further includes determining a translation of the rotatable interface relative to the display screen based, at least in part, on the resulting signal values received during the second time period.
