摘要： A display driver circuit may include a revision controller for controlling a nonvolatile memory having instructions by which control data for controlling devices controlled by the display driver circuit are changed, and a drive controller for controlling the devices based on the instructions. The revision controller determines whether to perform a read operation to the instructions based on electrical power being applied to the display driver circuit, and transfers instruction signals, which are generated based on the determination to perform the read operation, to the driving controller.

摘要： The present disclosure provides apparatuses including display driver circuits and operating methods thereof. In some embodiments, an electronic device includes a display panel, a nonvolatile memory, and a display driver circuit configured to receive frame data through a video interface channel, generate compensated frame data by compensating for the frame data by using compensation data, and send the compensated frame data to the display panel. The display driver circuit includes a display memory configured to store the compensation data, a compensation circuit configured to generate the compensated frame data from the frame data, a buffer memory, and a backup controller configured to monitor a status of the compensation circuit, and, when the compensation circuit is in an idle state, read partial data among the compensation data from the display memory, and write data present in the buffer memory in the nonvolatile memory.
