  • Patent number: 11942061
    Abstract: An electronic device includes a display panel that includes a first region including first pixel groups and a second region including second pixel groups, and a compensation circuit. The compensation circuit may receive first image data. The compensation circuit may compensate to generate second image data in response to a determination that the first image data corresponds to at least one of one or more particular first pixel groups that are adjacent to a boundary between the first region and the second region or one or more particular second pixel groups that are adjacent to the boundary. The compensation circuit outputs the second image data to the display panel.

  • Publication number: 20240062698
    Abstract: A display driver integrated circuit (IC) includes a data line driver that drives a first data line connected with a first pixel of a display in response to output image data, and a dithering circuit that receives a brightness value of the display, calculates a first reference grayscale value corresponding to the brightness value using a first group of threshold grayscale values, receives input image data with a first grayscale value, which corresponds to the first pixel, compares the first grayscale value and the first reference grayscale value, and generates the output image data having not the first grayscale value but an output grayscale value when the first grayscale value is smaller than the first reference grayscale value.

  • Publication number: 20230153591
    Abstract: The described techniques provide efficient semiconductor device configurations and improved processes for facilitating artificial intelligence operations. In an example, a semiconductor device may be configured with first memory for storing data before an artificial intelligence operation and second memory for storing data after an artificial intelligence operation. The use of the first memory and the second memory for storing data before and after the artificial intelligence operation, respectively, may support a simplified layout for a semiconductor device to facilitate artificial intelligence operations with minimal hardware configurations and limited software. In addition, the use of the first memory and the second memory for storing data before and after the artificial intelligence operation, respectively, may allow for processing when the domains of input data and output data are different.
