Display apparatus and method of operating the same

摘要

A display apparatus may include a first substrate defined by a pixel region and a transmitting region adjacent to the pixel region, the pixel region emitting light in a first direction and the transmitting region transmitting external light; a second substrate that faces the first substrate and seals pixels defined on the first substrate; an optical filter arranged on a first side of the display apparatus through which light is emitted, the optical filter being configured to transmit circularly polarized light that rotates in a predetermined direction; and an optical reflectance conversion device arranged on a second side of the display apparatus, opposite the first side, the optical reflectance conversion device being configured to change a reflectance of the external light according to modes of operation of the display apparatus.

1. A display apparatus, comprising:
a display device, the display device including: a first substrate; a second substrate, the second substrate facing the first substrate, and a display unit between the first substrate and the second substrate, the display unit including at least one pixel having a pixel region and a transmitting region, at least a portion of the pixel region emitting light and at least a portion of the transmitting region transmitting external light, the pixel including: at least one thin-film transistor; at least one first electrode electrically connected to the thin-film transistor, where the first electrode is an anode or a cathode; a pixel define layer disposed on the at least one first electrode, the pixel define layer including a first opening to expose at least a portion of the at least one first electrode and a second opening adjacent to the first opening; an organic film disposed on the at least a portion of the at least one first electrode; at least one second electrode disposed on the organic film and the pixel define layer, wherein at least one of sides of the second electrode is disposed on an area between the first opening and the second opening, the at least one second electrode is a reflection electrode, and the light emitted in the at least a portion of the pixel region goes through the first substrate; and wherein at least a portion of the second opening is formed in the transmitting region.
