Abstract: A display apparatus includes a display panel configured to display an image. The display panel includes a plurality of display areas. A display panel driver is configured to output a driving signal to the display panel. A backlight unit is configured to provide light to the display panel. A luminance compensating part is configured to generate a backlight compensating signal having different compensating values according to a distance between the display panel driver and the display areas of the display panel.

Abstract: A display device includes a substrate, pixels on the substrate, pads, and test lines. The pads are between the pixels and an edge of the substrate and include a first pad and a second pad. The test lines include a first test line and a second test line. The first test line includes a first section and a second section. The second section is closer to the edge of the substrate than the first section and is connected through the first section to the first pad. The second test line includes a first segment and a second segment. The second segment is closer to the edge of the substrate than the first segment and is connected through the first segment to the second pad. A minimum distance between the first section and the first segment is larger than a minimum distance between the second section and the second segment.

Abstract: A liquid crystal display comprises: an upper panel including an upper substrate on which a plurality of thin film layers are formed; a lower panel including a lower substrate on which a plurality of thin film layers are formed; a liquid crystal layer positioned between the upper panel and the lower panel; and a sealing member bonding between the upper panel and the lower panel and constraining the liquid crystal layer. The lower panel includes an aligning agent margin part which is positioned inside the sealing member on the lower substrate and dummy pixels which are positioned at the aligning agent margin part and which enclose a display area. By this configuration, it is possible for a liquid crystal display to be capable of reducing the peripheral area of the display panel so as to expand the display area or making the peripheral area seem smaller to make the display area seem larger.

Abstract: A display device includes a display panel including pixels disposed at rows and columns, first data lines respectively disposed at the columns, and second data lines respectively disposed at the columns, a first data driver connected to the first data lines, and a second data driver connected to the second data lines. A first portion of the pixels are connected to the first data lines, and a second portion of the pixels are connected to the second data lines. The first data driver provides first gray voltages corresponding to a first gamma curve to the first portion of the pixels through the first data lines, and the second data driver provides second gray voltages corresponding to a second gamma curve different from the first gamma curve to the second portion of the pixels through the second data lines.

Abstract: A display device includes a display panel, a gray-scale voltage generator, and a data driver. The data driver includes a first amplifier. The first amplifier includes a first voltage input terminal configured to receive a first voltage, a second voltage input terminal configured to receive a second voltage lower than both the first voltage and a common voltage to be applied to a pixel included in the display panel, an input terminal configured to receive a gray-scale voltage having a gray-scale level corresponding to image data, and an output terminal configured to output the data voltage as a buffered voltage corresponding to the gray-scale voltage.
