摘要： A display device includes a pixel, a first control pad, a second control pad, and a first dummy pad. The pixel may emit light with luminance corresponding to a data signal. Supply of the data signal to the pixel depends on a first control signal and a second control signal. The first control pad is connected to a first control line for supplying the first control signal. The second control pad is connected to a second control line for supplying the second control signal. The first dummy pad is positioned between the first control pad and the second control pad and may receive a first dummy signal. A voltage level of the first dummy signal is in a range from a voltage level of the first control signal to a voltage level of the second control signal.

摘要： A wiring-disconnection detecting circuit includes a low-power voltage supply, a monitoring wiring, and a wiring-disconnection determiner. The low-power voltage supply supplies a low-power voltage to a low-power voltage wiring that extends along a periphery of a display panel in a normal operating mode of the display panel and supplies a test voltage to the low-power voltage wiring in a wiring-disconnection detecting mode of the display panel. The monitoring wiring includes a first end connected to one point of the low-power voltage wiring and a second end at which a feedback voltage corresponding to the test voltage is output in the wiring-disconnection detecting mode. The wiring-disconnection determiner receives the feedback voltage from the second end, measures an RC delay of the feedback voltage, and determines that the low-power voltage wiring is disconnected when the RC delay is larger than a predetermined reference value.

摘要： An inspection system for a display cell having a display part and a plurality of data lines connected to first and second pixel units of the display part. An array test part and a lighting test part are located in a peripheral area around the display part. An inspection apparatus is configured to provide the array test part with an array control signal to block an array data signal from being applied to a plurality of data lines in a period in which a white image is displayed and to provide the lighting test part with a lighting control signal to block a lighting data signal from being applied to a plurality of data lines during a period in which a black image is displayed, during a drive reliability test mode for displaying a test image including the black image and the white image.

摘要： A display device includes a signal line disposed on a substrate. A signal input line is disposed on the substrate and connected to a driver. A first insulating layer is disposed on the signal line. A second insulating layer is disposed on the signal input line and the first insulating layer. First contact holes penetrate the first insulating layer and the second insulating layer and expose a portion of the signal line. Second contact holes penetrate the second insulating layer and expose a portion of the signal input line. A connecting member connects the signal line and the signal input line through the first and the second contact holes and is disposed on the second insulating layer. The first and the second contact holes are alternately arranged in the second insulating layer.
