A display apparatus is disclosed, which is capable of reducing the number of output channels in a column driving circuit. The display apparatus comprises a display portion including pixels arranged in pixel areas defined by row line groups and column line groups, a row driving circuit configured to supply a scan control signal to the row line groups, a column driving circuit configured to sequentially output a data signal every horizontal period, and a data distribution circuit configured to sequentially supply the data signal, which is sequentially output from each of output channels of the column driving circuit, to the column line groups in accordance with a data selection signal, wherein a period of the data selection signal is longer than 1 horizontal period.

Display apparatus

A display device with a substrate including an active area having a plurality of pixels, and an inactive area adjacent to the active area; a plurality of power lines in the active area, connected to the plurality of pixels; a first power link line in the inactive area configured to receive power voltage and transmit the power voltage to the plurality of power lines; and a first hole disposed in the first power link line.

Display device

An electroluminescent display device includes sub-pixels connected to gate lines, and a gate driver configured to supply a scan signal to at least one of the gate lines, and including stages. One of the stages includes a QB-node regulation unit configured to charge a QB-node and a QP-node to turn-on voltage by using a first gate clock signal and a second gate clock signal, and a pull-down unit configured to output a turn-off voltage in response to a voltage of the QP-node. The QB-node regulation unit includes a QP-node control part configured to invert a phase of a voltage of a Q1-node and apply the voltage of the inverted phase to the QP-node, and a QB-node control part configured to bootstrap the QP-node. Accordingly, by employing the gate driver including the QB-node regulation unit that provides a stable voltage to the QB-node and the QP-node, the reliability of the gate driver can be improved, and the bezel of the electroluminescence display device can be reduced.

Gate driver and electroluminescence display device including the same

A display device can include a substrate including an active area having a plurality of pixels and a non-active area adjacent to the active area; a plurality of power lines in the active area, configured to transmit a power voltage to the plurality of pixels, and including a plurality of first power lines and a plurality of second power lines; and a power link line disposed in the non-active area and including a lower power link line connected to the plurality of power lines, a first lower connecting line extending from the lower power link line, and a second lower connecting line extending from the lower power link line, in which the first and second lower connecting lines extend in a different direction than the lower power link line, the plurality of first power lines includes at least two sets of first power lines spaced apart from each other, and the plurality of second power lines includes at least two sets of second power lines spaced apart from each other.

A display panel and display device are provided that may be capable of sensing an external light source, such as a laser. The display device may include a display panel including gate lines, data lines, and sub-pixels defined at intersections between the gate lines and the data lines; a light source-sensing circuit in an inactive area of the sub-pixels to sense an external light source; and a monochromatic color filter pattern disposed on a sensor transistor of the light source-sensing circuit. Thus, the incident amount of an external light source other than a laser can be reduced, and the incident amount of the laser can be increased. Accordingly, it may be possible to decrease an initial off-current caused by an external light source and improve the sensitivity in laser sensing. Thus, the size of the sensor transistor can be reduced and aperture ratio can be increased.
