US 2026/0190753 A1 · DISPLAY APPARATUS

Abstract

Provided is a display apparatus including a substrate in which a plurality of sub pixels is defined. Each subpixel includes a first light emitting diode having a first electrode, an emission layer, and a second electrode, and a plurality of second light emitting diodes also having a first electrode, an emission layer, and a second electrode. The first electrode of the first light emitting diode and the first electrodes of the plurality of second light emitting diodes may be integrally formed, while the second electrode of the first light emitting diode and the second electrodes of the plurality of second light emitting diodes are electrically separated. A lens is disposed on the first light emitting diode or the plurality of second light emitting diodes and is configured to control a path of light emitted from the diodes. Through this arrangement, the display apparatus allows selective control of viewing characteristics.
