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 3D display device is provided. The 3D display device includes a display panel and a liquid crystal lens panel. The display panel operates in one of a 2D mode for displaying a 2D image, a 3D mode for displaying a 3D image, and a coincident mode for displaying the 2D image and the 3D image. The liquid crystal lens panel is disposed on the display panel. The liquid crystal lens panel is configured to refract the 3D image through a third region of the liquid crystal lens panel and to transmit the 2D image without refracting the 2D image when the display panel operates in the coincident mode.
