Abstract: An inspection system for inspecting a display device including pixels includes a camera for capturing the display device and providing a sensing image signal and an inspection device for receiving the sensing image signal and outputting a compensation signal for compensating for luminance of a defective pixel. The inspection device includes an image detector outputting a sensing input signal corresponding to the sensing image signal, a defect coordinate detector detecting the defective pixel based on the sensing input signal and outputting defect coordinates indicating a position of the defective pixel, an image analyzer analyzing consistency of the defect coordinates based on the sensing image signal and the sensing input signal and outputting final coordinates, and a defect compensation calculator outputting a compensation signal for adjusting luminance of compensation pixels adjacent to the defective pixel from among the pixels based on the final coordinates.

Abstract: A display device include: a display panel including first to third pixels, a data driver for providing first to third data voltages to the first to third pixels, and a scan driver for providing first and second scan signals to each of the first to third pixels. The scan driver performs a first active scan operation of sequentially providing the first and second scan signals to the first to third pixels in a first frame period, and perform a dummy scan operation of sequentially providing the second scan signal to the first to third pixels after the first active scan operation. The data driver changes a voltage level of at least one of the first to third data voltages in an overlap period in which the dummy scan operation and a second active scan operation of a second frame period are simultaneously performed.

Abstract: A method of generating compensation data for a display device is disclosed that includes measuring a front luminance and a side luminance of the display device, generating a front correction value and a side correction value based on the front luminance and the side luminance, respectively, determining a front background component of the front correction value and a side background component of the side correction value, generating a front background-synthesized side correction value by replacing the side background component with the front background component in the side correction value, and generating the compensation data based on the front correction value and the front background-synthesized side correction value.
