Abstract: The present invention provides a display apparatus that improves the uniformity of luminance among a plurality of pixels and improves chromaticity by recalibrating artifacts of a display image recognized by a visual sensation even after calibration is performed, and a method of controlling the same. The display apparatus may include a display panel; a communication circuitry configured to receive an initial calibration coefficient value of a first pixel and at least one second pixel except for the first pixel of the display panel; and a controller configured to compare luminance of the first pixel and the second pixel based on the initial calibration coefficient value, to modify the initial calibration coefficient value based on the comparison result, and to control the display panel based on the modified calibration coefficient value.

Abstract: The present disclosure relates to a display apparatus including a substrate, a thin film transistor disposed on the substrate, a first insulating layer disposed on a source electrode and a drain electrode of the thin film transistor, a light emitting diode disposed on the first insulating layer to emit light toward the substrate, a second insulating layer disposed on the first insulating layer to surround the light emitting diode, an upper electrode disposed on the second insulating layer, and a driver IC chip disposed above the upper electrode to be connected to the upper electrode. According to the above configuration, the driver IC chip is disposed on the back side of a light emitting surface of a display panel, so that a bezel is capable of being minimized or omitted, and manufacturing of the display apparatus is easy and manufacturing costs is reduced.
