摘要： A display device includes a display panel and a scan driving circuit. The display panel includes a plurality of pixels and a plurality of sensors. The scan driving circuit drives a plurality of scan lines. Pixels in a j-th row among the plurality of pixels are connected to a j-th scan line among the plurality of scan lines, in which j is a positive integer. Sensors, which correspond to the pixels in the j-th row, from among the plurality of sensors are connected to an a-th scan line among the plurality of scan lines, in which a is a positive integer different from j.

摘要： A display apparatus includes a display panel configured to display an image, a data driver including a voltage generator configured to convert an image data applied thereto to a data voltage and a buffer configured to apply the data voltage to the display panel, a timing controller including a mode controller configured to generate a mode selection signal on the basis of an image frame rate of the image data. The data driver is configured to be operated in a power cut-off mode or a stand-by mode in response to the mode selection signal. The driving voltage switch is configured to cut off the analog driving voltage applied to at least one of the buffer and the voltage generator during the power cut-off mode and the bias controller is configured to reduce a bias current in the stand-by mode.

摘要： A display device and a method of compensating a luminance of the display device enhance display quality and reducing storage capacity of a memory, the display device including: a display panel including a plurality of pixels arranged in a matrix form; a storage unit storing a gray level compensation value of a reference pixel defined by at least one pixel; a compensation circuit receiving a gray level datum and generating a compensated gray level datum by applying the gray level compensation value; and a data driving circuit receiving the compensated gray level datum to generate a data voltage and outputting the data voltage to the display panel. The display panel includes a first compensation area and a second compensation area. The reference pixel in the first compensation area is defined by one pixel and the reference pixel in the second compensation area is defined by m×n pixels, m and n being natural numbers greater than 1.

摘要： A mask substrate inspection system includes a measurement target module, a camera module, and a control module. The measurement target module includes a mask substrate and a surface light source supplying a light to the mask substrate. The camera module generates image information of the mask substrate using the light from the surface light source. The control module determines whether defects are present in the mask substrate using the image information, without damaging the mask substrate.
