摘要： A horizontal line driver providing a scan signal to scan lines, and including: first scan signal output blocks providing the scan signal to scan lines in a first side display area, wherein each of the first scan signal output blocks include a first output buffer; second scan signal output blocks providing the scan signal to scan lines in a first front display area including curved edges, wherein each of the second scan signal output blocks include a second output buffer; and third scan signal output blocks providing the scan signal to scan lines in a second front display area. Each of the third scan signal output blocks include a third output buffer. The width of the first front display area is larger than a width of the first side display area but is smaller than a width of the second front display area, and the width gradually increases.

摘要： An organic light emitting display device includes a display panel including and a plurality of pixels, a gate driver configured to a normal gate signal and an alternative gate signal to the pixels, a data driver configured to provide a data signal to the pixels, an emission control driver configured to an emission control signal to the pixels, and a controller configured to control the gate driver, the data driver, and the emission control driver. Each of the pixels is driven by the normal gate signal in a first driving mode and is driven by the alternative gate signal in a second driving mode. A threshold voltage of a first transistor is compensated in the first driving mode and the threshold voltage of the first transistor is not compensated in the second driving mode.

摘要： A method of driving a display panel is provided. The method includes generating first compensated and second compensated data based on input image data, outputting the first compensated data to a data driver during a first frame, outputting the first smoothing data to the data driver during a second frame subsequent to the first frame, and outputting the second compensated data to the data driver during an n-th frame subsequent to the second frame (where n is a natural number greater than two). The first smoothing data has a value between a value of the first compensated data and a value of the second compensated data.

摘要： A method of driving a display panel is proposed. The method includes determining whether an input image data represents a video image or a static image, determining whether an image transition occurs in the input image data when the input image data represents the static image, and inserting a plurality of image sticking compensation frames between normal frames in a low frequency driving when the image transition occurs in the input image data between the normal frames. The number of the image sticking compensation frame may be properly adjusted during a cycle of low frequency driving.
