摘要： Disclosed is a display driver integrated circuit (IC) which includes a data line driver that drives a first data line connected with a first pixel of a display in response to output image data, and a dithering circuit that receives a brightness value of the display, calculates a first reference grayscale value corresponding to the brightness value using a first group of threshold grayscale values, receives input image data with a first grayscale value, which corresponds to the first pixel, compares the first grayscale value and the first reference grayscale value, and generates the output image data having not the first grayscale value but an output grayscale value when the first grayscale value is smaller than the first reference grayscale value.

摘要： A display driver integrated circuit includes a frame buffer, a plurality of image processing circuits and an image processing controller. The frame buffer sequentially stores a plurality of frame data received from a host processor. Each of the plurality of frame data includes a plurality of data slices. The image processing circuits perform image signal processing operations, respectively, on ones of the data slices that are included in a respective one of the plurality of frame data and which are sequentially retrieved from the frame buffer. The image processing controller bypasses at least one of the image processing circuits by applying a bypass control signal to the image processing circuits based on a first plurality of data slices included in a first one of the plurality of frame data and a second plurality of data slices included in a second one of the plurality of frame data.

摘要： A luminance compensator includes a memory device and a luminance compensation circuit. The memory device stores a plurality of luminance compensation data and provides first luminance compensation data and second luminance compensation data among the plurality of luminance compensation data in response to a frame rate dimming-on signal. The first luminance compensation data corresponds to a first frame rate. The second luminance compensation data corresponds to a second frame rate. The plurality of luminance compensation data is for compensating luminance of at least one region that operates with a plurality of frame rates. The frame rate dimming-on signal represents time intervals in which frame rates of the at least one region are gradually changed. The luminance compensation circuit generates third luminance compensation data in response to the frame rate dimming-on signal, the first luminance compensation data, and the second luminance compensation data.
