A touch recognition enabled display device includes a plurality of common electrode blocks serving as touch-sensing regions and/or touch-driving regions. Conductive lines connected to the common electrode blocks are placed under the common electrode blocks and the pixel electrodes of the pixels, and they are routed across the active area, directly toward an inactive area where drive-integrated circuits are located. The conductive lines are positioned under one or more planarization layers, and are connected to the corresponding common electrode blocks via one or more contact holes.

A touch recognition enabled display panel includes a plurality of common electrode blocks serving as touch-sensing regions and/or touch-driving regions. Conductive lines connected to the common electrode blocks are placed under the common electrode blocks and the pixel electrodes of the pixels, and they are routed across the active area, directly toward an inactive area where drive-integrated circuits are located. The conductive lines are positioned under one or more planarization layers, and are connected to the corresponding common electrode blocks via one or more contact holes.

Touch recognition enabled display panel with asymmetric black matrix pattern

A liquid crystal display panel includes features to prevent damage to the liquid crystal alignment layer when a color filter substrate and a thin-film transistor array substrate are moved relative to each other. The liquid crystal display panel may include a column spacer on the color filter substrate under the black matrix and a bump pattern on the array substrate where the column spacer and the bump pattern are in contact with each other. The array substrate may otherwise include a planarization layer with a step portion and a protective layer on the planarization layer where the protective layer is in contact with the column spacer.

Array substrate and liquid crystal display device including the same

A display of an electric device includes a plurality of separated transparent electrode blocks, which are configured to provide one or more of supplemental features such as touch recognition. Signal paths between the transparent electrode blocks and the driver for the supplemental feature are implemented with a plurality of conductive lines placed under positioned under one or more planarization layers. The conductive lines implementing the signal paths are routed across the display area, directly toward a non-display area where drive-integrated circuits are located.

Display with separated electrode blocks

A display device according to an embodiment includes a plurality of driving blocks including a plurality of gate lines and a gate shorting structure spaced apart from the gate lines by an amount equal to a trimming region; an equipotential line extending from one of the driving blocks to an adjacent driving block, part of which is removed by the amount equal to the trimming region; a gate dummy line extending from at least one of the driving blocks; a plurality of data lines intersecting the gate lines; and an active layer disposed between the gate dummy line and the data lines, wherein some part of the active layer that overlaps the gate dummy line but does not overlap the data lines is removed.
