Abstract: A display device includes a display layer on which a display area and a non-display area adjacent to the display area are defined and a sensor layer on which a plurality of sensor units are defined. The plurality of sensor units includes a first sensor unit overlapping the display area and a second sensor unit overlapping the display area and the non-display area. The second sensor unit includes a first portion and a second portion expanded from the first portion, and the first portion has a shape that is the same as a shape of which a portion is removed from the first sensor unit, and a width of the second sensor unit in a first direction is greater than a width of the first sensor unit in the first direction.

Abstract: An electronic panel includes a base substrate having a first area, a second area adjacent to the first area, and a third area adjacent to the second area, a plurality of pixels in the second area, a plurality of pixel signal lines in the third area and connected to the pixels, a crack detecting pattern spaced apart from the pixels and in the first area, a first line spaced apart from the pixel signal lines, in the third area, and connected to a portion of the crack detecting pattern, and a second line spaced apart from the pixel signal lines, in the third area, connected to another portion of the crack detecting pattern, and spaced apart from the first line. The crack detecting pattern has a line-symmetrical shape with respect to a symmetry axis passing through a center of the first area.

Abstract: Provided is an input detection unit with a plurality of first electrodes and second electrodes insulated from the first electrodes. Dummy patterns are disposed between the patterns and the detection patterns. A secondary dummy pattern is disposed adjacent to the dummy patterns. Signal lines overlap the non-detection area. The signal lines include a first signal line connected to the patterns and a second signal line connected to the detection patterns. The plurality of patterns includes a row of patterns closest to the non-detection area. The secondary dummy pattern overlaps a portion between the row of patterns closest to the non-detection area and the second signal line.

Abstract: A display panel driving apparatus includes a data driver, a gate driver, an extra resistance part through which a constant current passes, and a circuit configured to generate a first gamma voltage, and output a first extra gamma voltage indirectly to the data driver through the extra resistance part. The data driver is configured to generate a data signal based on the first gamma voltage and output the data signal to a data line of a display panel. The gate driver is configured to output a gate signal to a gate line of the display panel.
