Abstract: 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.

Abstract: 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.
