Patent Issued for Organic Light-Emitting Display Apparatus and Method of Manufacturing the Same Including RGB Insulating Layer Configuration (USPTO 9570710)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- SAMSUNG DISPLAY CO., LTD. (Yongin, Gyeonggi-Do, KR) has been issued patent number 9570710, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Oh, Jaehwan (Yongin, KR); Choi, Jaebeom (Yongin, KR); Park, Sehun (Yongin, KR); Son, Yongduck (Yongin, KR); Lee, Jiyoun (Yongin, KR); Chang, Youngjin (Yongin, KR).

This patent was filed on April 28, 2015 and was published online on February 14, 2017.

From the background information supplied by the inventors, news correspondents obtained the following quote: "One or more exemplary embodiments relate to a display apparatus, for example, to an organic light-emitting display apparatus and a method of manufacturing the same.

"Among display apparatuses, an organic light-emitting display apparatus may have a wide viewing angle, an excellent contrast ratio, and a high response speed, and may be regarded as a next-generation display apparatus."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "Embodiments may be realized by providing an organic light-emitting display apparatus, including a substrate; a first reflective layer, a second reflective layer, and a third reflective layer that are separately disposed on the substrate; a first insulating layer on the first reflective layer, but not on the second reflective layer and the third reflective layer; a second insulating layer on the first insulating layer and the second reflective layer, but not on the third reflective layer; and a first pixel electrode for red emission on the second insulating layer and corresponding to the first reflective layer, a second pixel electrode for green emission on the second insulating layer and corresponding to the second reflective layer, and a third pixel electrode for blue emission on the third reflective layer.

"The first pixel electrode, the second pixel electrode, and the third pixel electrode may be transparent electrodes.

"The first insulating layer and the second insulating layer may be transparent insulating layers.

"Each of the first reflective layer, the second reflective layer, and the third reflective layer may include a metal material.

"The organic light-emitting display apparatus may further include a thin-film transistor electrically connected to each of the substrate, the first pixel electrode, the second pixel electrode, and the third pixel electrode. The thin-film transistor may include a semiconductor layer, a gate electrode, and source and drain electrodes, and each of the first reflective layer, the second reflective layer, and the third reflective layer may include a same material as one or more of the gate electrode or the source and drain electrodes of the thin-film transistor.

"The first insulating layer may not be between the second pixel electrode and the second reflective layer and may not be between the third pixel electrode and the third reflective layer.

"The second insulating layer may not be between the third pixel electrode and the third reflective layer.

"The organic light-emitting display apparatus may further include a common layer on the first pixel electrode, the second pixel electrode, and the third pixel electrode, a red emission layer on the common layer and corresponding to the first pixel electrode, a green emission layer on the common layer and corresponding to the second pixel electrode, and a blue emission layer on the common layer and corresponding to the third pixel electrode.

"The organic light-emitting display apparatus may further include an opposite electrode on the red emission layer, the green emission layer, and the blue emission layer and corresponding to the first pixel electrode, the second pixel electrode, and the third pixel electrode. A first distance between a surface of the first reflective layer facing the opposite electrode and a surface of the opposite electrode that corresponds to the first pixel electrode and faces the first pixel electrode may conform to an n.sup.th resonance distance of light emitted from the red emission layer, a second distance between a surface of the second reflective layer facing the opposite electrode and a surface of the opposite electrode that corresponds to the second pixel electrode and faces the second pixel electrode may conform to an n.sup.th resonance distance of light emitted from the green emission layer, and a third distance between a surface of the third reflective layer facing the opposite electrode and a surface of the opposite electrode that corresponds to the third pixel electrode and faces the third pixel electrode may conform to an n.sup.th resonance distance of light emitted from the blue emission layer, where n is a natural number.

"The organic light-emitting display apparatus may further include a third insulating layer on the second insulating layer and between the third pixel electrode and the third reflective layer.

"Embodiments may be realized by providing a method of manufacturing an organic light-emitting display apparatus, the method including preparing a substrate, and forming a first reflective layer, a second reflective layer, and a third reflective layer on the substrate such that the first reflective layer, the second reflective layer, and the third reflective layer are separate from each other; forming a first insulating layer on the first reflective layer, but not on the second reflective layer and the third reflective layer; forming a second insulating layer on the first insulating layer and the second reflective layer, but not on the third reflective layer; and forming a first pixel electrode for red emission, a second pixel electrode for green emission, and a third pixel electrode for blue emission that correspond to the first reflective layer, the second reflective layer, and the third reflective layer, respectively, that are separately formed on the substrate.

"The first pixel electrode, the second pixel electrode, and the third pixel electrode may be formed as transparent electrodes.

"The method may further include forming a third insulating layer on the second insulating layer and between the third pixel electrode and the third reflective layer.

"The first insulating layer, the second insulating layer, and the third insulating layer may be formed as transparent insulating layers.

"Each of the first reflective layer, the second reflective layer, and the third reflective layer may be formed of a metal material.

"The method may further include forming a thin-film transistor electrically connected to each of the first pixel electrode, the second pixel electrode, and the third pixel electrode. Forming the thin-film transistor may include forming a semiconductor layer, a gate electrode, and source and drain electrodes, and forming the first reflective layer, the second reflective layer, and the third reflective layer may simultaneously be performed with one of forming the gate electrode or forming the source and drain electrodes.

"The method may further include forming a common layer on the first pixel electrode, the second pixel electrode, and the third pixel electrode; and forming a red emission layer, a green emission layer, and a blue emission layer on the common layer. The red emission layer, the green emission layer, and the blue emission layer may correspond to the first pixel electrode, the second pixel electrode, and the third pixel electrode, respectively."
