  • Patent number: 11942016
    Abstract: A display device includes: a gain provider configured to set a time point elapsed by a set period from a time point at which a first region of an input image is detected as a still region, as a set time, and to gradually decrease a gain value from the set time; and a grayscale converter configured to generate an output image by applying the gain value to the first region and a second region including a peripheral region of the first region among the input image, wherein the gain provider is configured to set the set period differently according to size of grayscale values in the first region.

  • Publication number: 20240096258
    Abstract: A display device includes blocks each including two or more pixels commonly coupled to a first power line, and a first power voltage controller for determining a margin value of a first power voltage supplied to the first power line, based on load values of the blocks. The first power voltage controller determines the load values based on grayscale values of the pixels included in each of the blocks. The magnitude of the first power voltage is determined to become smaller as the margin value becomes larger. The margin value includes a first margin value. The first power voltage controller determines the first margin value according to a degree of distribution of load values of first blocks arranged in a first direction among the blocks.

  • Patent number: 11935488
    Abstract: A display device includes a display panel, a power supply a current measurer, a controller, and a sensor. The display panel includes pixels connected between first and second power lines. The power supply applies power voltages to the first and second power lines. The current measurer measures a current applied to the display panel from the power supply through the first and second power lines. The controller outputs a first sensing control signal indicating whether to sense a voltage-current characteristic of the light emitting element of at least one of the pixels based on a measured current. The sensor senses the voltage-current characteristic of the light emitting element in response to the first sensing control signal.
