  • Patent number: 12225358
    Abstract: The present disclosure relates to a technique for selectively reproducing multiple sounds for respective areas of a display through image analysis for each display area. A technique, for individually controlling multiple audio devices by analyzing an image to extract regions of the image and classifying sound types through data learning, can be provided.

  • Publication number: 20240321221
    Abstract: A display driving apparatus includes a display panel comprising a first display area displaying a first image and a second display area being maintained in a turn-off state during a hybrid mode; a source driving circuit configured to supply a first source signal to first pixels included in the first display area and supply a second source signal to second pixels included in the second display area to sense electrical characteristics of the second pixels when the display panel operates in the hybrid mode; and a timing controller configured to transfer first image data for the first image and sensing data for sensing to the source driving circuit and compensate for second image data for a second image which is to be displayed after displaying of the first image, based on a target compensation value obtained from the electrical characteristics sensed by the source driving circuit, wherein the target compensation value is determined based on a third image displayed in a previous display mode of the hybrid mode.

  • Patent number: 12033587
    Abstract: A display driving apparatus includes a source driving circuit supplying a first source signal to a first display area to display a first image and supply a second source signal to a second display area to sense characteristics of a pixels of the second display area when a display panel operates in a hybrid mode, the second display area being in a turn-off state during the hybrid mode, a gate driving circuit supplying a gate pulse to first gate lines of the first display area and supply the gate pulse to target gate lines of the second display area, a timing controller transferring first image data for the first image and sensing data for sensing to the source driving circuit and compensate for second image data for a second image which is to be displayed after the first image, based on a target compensation value obtained from a sensing result.

  • Publication number: 20240194160
    Abstract: The present disclosure relates to a display apparatus and control method thereof. The display apparatus includes a receiver configured to receive input image data, an accumulator configured to generate a cumulative data count by analyzing a degree of degradation according to the received input image data and a burn-in factor, an interpolator configured to update the cumulative data count in a memory by applying an adaptive weight to the generated cumulative data count, and a compensator configured to generate compensation data using the input image data and the updated cumulative data count.
