Display apparatus

Abstract

The present disclosure relates to a display apparatus, and the display apparatus includes a display panel on which a plurality of sub-pixels are disposed, the plurality of sub-pixels each including an organic light-emitting diode, a base voltage node connected to a cathode electrode of the organic light-emitting diode, a plurality of driving voltage lines disposed on the display panel and configured to supply a driving voltage of the organic light-emitting diode to the plurality of sub-pixels, a controller configured to control a gate driving circuit and a data driving circuit, and a defect detection circuit configured to determine whether a defect occurs in the driving voltage line based on a voltage sensed at the base voltage node, wherein, based on a defect signal output from the defect detection circuit, an output of at least one of the controller, the gate driving circuit, and the data driving circuit is controlled.

Dependencies are inferred from the claim text.
