Abstract: A test method includes generating first image data by imaging a display panel including pixels, generating boundary data by detecting a spot area in the display panel based on the first image data, generating second image data by deblurring the first image data with respect to a boundary area disposed at a boundary of the spot area based on the boundary data and generating correction data by setting a correction area including the boundary area based on the second image data.

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 system for compensating a stain in a display device including a display panel including pixels and a driving controller, an imaging unit, and an inspection device including a defect characteristic classifying unit, and a compensation data generating unit. The inspection device generates first measurement data and second measurement data. The inspection device compares second image data with compensation data that is based on the first and second measurement data, and the defect characteristic classifying unit classifies, as a first defect pixel or a second defect pixel a plurality of pixels, based on the first measurement data, the second measurement data, and the second image data. The compensation data generating unit generates a first compensating value for compensating for the first defect pixel in a first pixel unit, and a second compensating value for compensating for the second defect pixel in a second pixel unit different from the first unit.

Abstract: A method of detecting a stain of a display panel is disclosed that includes capturing a first color image of the display panel, capturing a second color image of the display panel, generating a merged image by merging a color coordinate map of the first color image and a color coordinate map of the second color image, generating a background image of the merged image by a morphology filtering, generating a flattened image by operating the merged image and the background image and detecting an area of the flattened image in which a color coordinate value exceeds a threshold value as a stain area.

Abstract: A display device includes: a display panel, which includes a pixel; a voltage generator, which generates a driving voltage for an operation of the display panel; and a driving controller, which receives an input image signal and outputs an output image signal obtained by compensating for the input image signal based on a characteristic of the display panel. The driving controller includes: a control unit, which outputs an error correction value corresponding to a voltage difference between a voltage level of the driving voltage provided from the voltage generator and a voltage level stored in advance in the control unit when the driving voltage is provided from the voltage generator; and an image correction unit. which converts the input image signal into the output image signal based on the error correction value.

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.
