  • Display driving circuit and operating method thereof
    Patent number: 11217199
    Abstract: Disclosed are a display driving circuit and a display apparatus including the same. A display driving circuit includes a first amplifier configured to drive a first data line of a display panel based on first pixel data and a second amplifier configured to drive a second data line of the display panel based on second pixel data, wherein, when a first data difference between the first pixel data and the second pixel data is greater than or equal to a data value indicating one grayscale and is less than or equal to a first threshold value, the second amplifier is turned off, and the first amplifier is configured to drive the first data line and the second data line based on the first pixel data and the second pixel data.
    Type: Grant
