摘要: An electronic device is provided. The electronic device includes a display that is configured to show content that includes a plurality of frames. The plurality of frames includes a first frame that is associated with a pre-transition value. The plurality of frames also includes a second frame that is associated with a current frame value that corresponds to a first luminance. Additionally, the electronic device is configured to determine an overdriven current frame value corresponding to a second luminance that is greater than the first luminance. The electronic device is also configured to display the second frame using the overdriven current frame value.

摘要: A mobile electronic device includes a display having an active array and a reference array. The active array includes a pixel and the reference array includes a reference pixel. The mobile electronic device also includes processing circuitry communicatively coupled to the display. The processing circuitry is configured to instruct the active array to drive the pixel based at least in part on a current-voltage relationship of the pixel and a reference current-voltage relationship of the reference pixel.

摘要: A mobile electronic device includes a display having an active array and a reference array. The active array includes a pixel and the reference array includes a reference pixel. The mobile electronic device also includes processing circuitry communicatively coupled to the display. The processing circuitry drives the pixel based at least in part on a degraded current-voltage relationship of the pixel, a reference current-voltage relationship of the reference pixel, and an aged current-voltage relationship.

摘要: An electronic device may include an electronic display having multiple pixels to display an image based on processed image data. Each of the pixels may include multiple sub-pixels. The electronic device may also include image processing circuitry to receive input image data, in a first color space, having luminance values for each of the sub-pixels. The circuitry may also map the input image data from the first color space to a second color space and apply a multi-dimensional lookup table, based on the input image data in the second color space, to generate compensated image data. The lookup table may receive the luminance values for each of the sub-pixels and output corrected luminance values compensated for an expected amount of current leakage between the sub-pixels. The circuitry may also inversely map the compensated image data from the second color space to the first color space to generate the processed image data.

摘要: An electronic device may include an electronic display having multiple pixels to display an image based on processed image data. Each of the pixels may include multiple sub-pixels. The electronic device may also include image processing circuitry to receive first image data for a sub-pixel of the and second image data for a group of sub-pixels surrounding the sub-pixel. The first image data may include a luminance value for the sub-pixel and the second image data may include luminance values for each sub-pixel of the group. The image processing circuitry may also determine a compensation value, to compensate the luminance value for lateral current leakage between the sub-pixel and the group of sub-pixels, based on the luminance value of the sub-pixel and the luminance values for each sub-pixel of the group of sub-pixels.

摘要: An electronic device may have a camera and a display. The display may be configured to display virtual reality content for a user in which no real-world content from the camera is displayed or mixed reality content in which a combination of real-world content from the camera and overlaid virtual reality content is displayed. Control circuitry in the device may adjust the display and camera while transitioning between virtual reality and mixed reality modes. The control circuitry may reconfigure the camera to exhibit a desired frame rate immediately upon transitioning from virtual reality mode to mixed reality mode. Transitions between modes may be accompanied by smooth transitions between frame rates to avoid visible artifacts on the display. The camera frame rate may be synchronized to the display frame rate for at least part of the transition between the virtual reality and mixed reality modes.

摘要: The present disclosure relates to systems and methods of accounting for the kickback voltage in an LCD display. For example, a method may include obtaining, via a processor, a difference between a nominal voltage of a common electrode of a display and a measured voltage of the common electrode. The processor may obtain image data associated with an image to be displayed on the display. The processor may adjust the image data of a pixel of the display based on the difference. The processor may output an image signal indicative of the adjusted image data to a pixel electrode of the pixel.
