Abstract: A display panel may comprise a first pixel including a first light emitting diode for emitting light based on a first current received from a first power voltage, a second pixel including a second light emitting diode for emitting light based on a second current received from the first power voltage, and a common transistor forming a first current path through which the first current flows between a first power source for supplying the first power voltage and the first light emitting diode, and forming a second current path through which the second current flows between the first power source and the second light emitting diode, in response to an emission control signal.

Abstract: 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.
