Display device including abnormal pixels and operation method thereof

Abstract

A display device is disclosed. The display device includes: a plurality of light-emitting elements including light emitting circuitry comprising a plurality of subpixels of a display panel, a light emitting diode (LED) driving circuit configured to drive the plurality of light emitting elements, a substrate on which the plurality of light emitting elements and the LED driving circuit are disposed, memory storing an abnormal pixel area and LED arrangement information of the abnormal pixel area, and at least one processor, comprising processing circuitry, individually and/or collectively, configured to control the LED driving circuit such that a signal corresponding to gradation information corresponding to each of the plurality of light emitting elements is provided based on specified LED color positions, wherein at least one processor, individually and/or collectively, is configured to control the LED driving circuit such that a signal corresponding to the LED arrangement information of the abnormal pixel area is provided instead of the specified LED color positions, with respect to the plurality of light-emitting devices in the abnormal pixel area.
