A display device includes first lead lines connecting the circuit signal lines with the driving integrated circuit, and second lead lines connecting the panel signal lines with the driving integrated circuit, wherein the second lead lines comprise a 2-1 sub-lead line configured to supply a scan-high voltage signal from the driving integrated circuit to the panel signal lines, and a 2-2 sub-lead line configured to supply a scan-low voltage signal from the driving integrated circuit to the panel signal lines, wherein the first lead lines comprises a 1-1 sub-lead line connected to the driving integrated circuit, a 1-1-1 sub-lead line separated from the 1-1 sub-lead line in a first direction, a 1-2 sub-lead line spaced apart from the 1-1 sub-lead line in a second direction intersecting the first direction, and a 1-2-1 sub-lead line spaced apart from the 1-2 sub-lead line in the second direction.

Display device

A display device includes a touch panel (TP), a transparent adhesive member (TAM) on a surface of the TP, a touch printed circuit board (TPCB), and a display panel (DP) on a surface of the TAM. The TP includes a sensing portion and a pad side portion (PSP) on a side of the sensing portion. The TPCB includes a contact portion (CP) attached to a surface of the PSP. The DP includes a substrate, an optical film (OF) on a surface of the substrate, and a bending protection layer (BPL) on a side of the OF on the surface of the substrate. The surface of the PSP includes a connection area attached to the CP and a non-connection area not attached to the CP. The OF is spaced from the BPL with a gap disposed therebetween. The TAM overlaps, in a thickness direction, with the TPCB and the gap.

A display apparatus includes a display panel, an electrode, a first wiring, a second wiring, a first contact hole, a second contact hole and a first resistor. The display panel includes an active area to display an image and a peripheral area adjacent to the active area. The electrode is in the active area. The first wiring is in the peripheral area and configured to apply a power voltage to the electrode. The second wiring is in the peripheral area and configured to apply the power voltage to the electrode. The first contact hole connects the electrode and the first wiring. The second contact hole connects the electrode and the second wiring. The first resistor is connected between the first wiring and the second wiring.

Display apparatus and method of detecting defect of the same

A display device includes a display panel having a display area and pixels at the display area, a power supply configured to supply a first power source voltage to the pixels through a first power line extending to the display area, and to supply a second power source voltage lower than the first power source voltage to the pixels through a second power line including first and second side power lines extending in first and second peripheral areas located at first and second sides of the display area of the display panel, a sensor configured to detect first and second detection values corresponding to currents of the first and second side power lines, and a controller configured to control an operation of the power supply, based on a difference between the first detection value and the second detection value.

Provided are an apparatus for manufacturing an OLED display and a method of manufacturing OLED display. According to another aspect of the present invention, there is provided the method of manufacturing an OLED display which includes placing a substrate having rows and columns of pixels through on a stage, ejecting organic light-emitting ink to the pixels through on the substrate by using a print head placed above the stage, and sequentially covering pixels through coated with the organic light-emitting ink with a cover plate placed above the stage.
