  • Patent number: 11915668
    Abstract: A display device includes a display panel including a plurality of pixels, a display panel driver, and a zone compensating circuit which divides the display panel into a plurality of unit blocks, obtains load values of input image data for the unit blocks, and generates corrected image data by correcting the input image data based on the load values. Each of the load values corresponds to one of the unit blocks. The display panel driver generates a data signal for displaying an image on the display panel based on the corrected image data. When grayscale values included in the input image data are the same, a luminance of the image displayed on the display panel is decreased moving away from a center of a reference block having a largest load value among the unit blocks based on the corrected image data.

  • Publication number: 20230198651
    Abstract: A slave node calculates and stores a propagation delay generated when exchanging a message with a master node. The master node transmits a reference time indicated by a hardware clock of the master node, and the slave node synchronizes a hardware clock of the slave node to the reference time indicated by the hardware clock of the master node. The master node transmits a time value in a first time domain to the slave node, where the time value is calculated by the master node by adding an offset of the first time domain to the reference time. The slave node calculates the offset using the time value and the stored propagation delay, and obtains a time in the first time domain by applying the calculated offset to a reference time indicated by the hardware clock of the slave node.
