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.

Abstract: A display driving circuit for driving a display panel includes a control logic that adjusts brightness of a first partial area by adjusting pixel data values included in partial image data to be displayed on the first partial area of the display panel based on received brightness control information, and a data driver that generates image signals by digital-analog conversion of pixel data values provided from the control logic, the data driver providing the image signals to the display panel.

Abstract: A method of transmitting information by an electronic device is provided. The method includes collecting log information, determining whether a keep-alive message transmission period arrives, and when the keep-alive message transmission period arrives, transmitting the log information to a push server.
