MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202514082897 A) filed by Lg Display Co. , Ltd. on September 01, 2025, for Organic Light Emitting Display Apparatus.
Inventor includes Gong, Hyojoon.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: An organic light emitting display apparatus is disclosed, including a substrate (100) having a plurality of subpixels (SP1, SP2, SP3); a pixel defining layer (PDL) on the substrate (100) and defining a light emitting opening (OPE); a partition wall (105) on the pixel defining layer (PDL) and defining a partition wall opening (OPP) corresponding to the light emitting opening (OPE); and a light emitting element (ED) corresponding to the partition wall opening (OPP). The partition wall opening (OPP) includes a center opening (OPPa), a first partition wall opening (OPPb) extending in a first direction from the center opening (OPPa), a second partition wall opening (OPPc) extending in a second direction overlapping the first direction, and a third partition wall opening (OPPd) extending in a third direction overlapping both the first and second directions. The plurality of subpixels (SP1, SP2, SP3) is respectively disposed in the first, second, and third partition wall openings (OPPb, OPPc, OPPd), enabling separation and arrangement of subpixels (SP1, SP2, SP3) within a shared structure for efficient light emission without using a fine metal mask.
