The application the USPTO published on July 2, 2026 — US20260190833A1, "Display Device," assigned to LG Display Co., Ltd. — claims a way to suppress OLED glare by ordering three layers on top of the touch sensor. Before walking the claim, the procedural posture matters: this is a published application, not a granted patent. The USPTO publishes applications roughly eighteen months after their earliest priority date, before examination concludes, so the claim language read here is what LG Display is seeking, not a right that has issued. Scope can narrow in prosecution, and nothing below should be read as characterizing what the applicant will ultimately be allowed.

With that fixed, the first independent claim is worth taking limitation by limitation, because the invention lives entirely in the order of the stack. The claim recites a substrate with an active area of sub-pixels and an adjacent non-active area; a plurality of light-emitting elements in those sub-pixels; an encapsulation structure covering them; a touch sensing structure on the encapsulation, carrying the touch electrodes; a black matrix on that touch sensing structure; a plurality of metal patterns disposed in an opening of the black matrix; and an organic dye layer on the metal patterns. Every element is a layer, and the claim's work is the sequence: the anti-reflection components — black matrix, metal patterns, dye — are stacked above the touch sensor, with the metal patterns seated inside the black matrix's opening.

A display device comprising: a substrate including an active area in which a plurality of sub-pixels is disposed and a non-active area adjacent to the active area; a plurality of light emitting elements disposed in the plurality of sub-pixels on the substrate; an encapsulation structure disposed to cover the plurality of light emitting elements; a touch sensing structure disposed on the encapsulation structure and including a plurality of touch electrodes; a black matrix disposed on the touch sensing structure; a plurality of metal patterns disposed in an opening of the black matrix; and an organic dye layer disposed on the plurality of metal patterns.— Display Device, US20260190833A1

The element that carries the claim

The operative limitation is the placement of the metal patterns inside the opening of the black matrix, on top of the touch sensing structure, with the organic dye layer over them. A black matrix over a touch sensor is, on its own, familiar; a dye layer over emitters is familiar. What the claim ties together is metal patterns seated in the black matrix opening — over each pixel's exit — beneath a dye layer, on the touch stack. That combination is where an examiner's novelty and obviousness analysis would concentrate, and it is the coordinate a practitioner mapping this filing would record: not "an anti-reflection OLED," but this specific ordering of absorber, in-opening metal, and dye above the touch sensor.

The application does not rest on a single independent claim. A second independent claim (claim 9) recites the metal patterns as "positioned on the same layer as the black matrix" and disposed in the opening to overlap the emission area — a formulation that pins the metal patterns and black matrix to a common layer rather than merely stacking them. A third independent claim (claim 17) drops the dye from the base recitation and instead claims the metal pattern's geometry directly: "a basal segment extending horizontally relative to the substrate and a sidewall segment extending vertically from an edge of the basal segment along a side surface of the black matrix defining the opening." Read together, the three independents cover the same physical structure from three angles — the ordered stack, the same-layer relationship, and the metal pattern's cross-section — the conventional way an applicant hedges which limitation ends up doing the distinguishing work.

The dependent claims fill in the geometry a litigator or licensing analyst would want to see. Claim 2 recites that the metal patterns are thinner than the black matrix. Claim 3 splits each metal pattern into a first portion on the touch structure inside the opening and a second portion on the side surface of the black matrix, of equal thickness — the same basal-and-sidewall shape the third independent claim recites. Claims 4 through 7 then define the dye's coverage: claim 4 has one dye layer integrally covering both emission and non-emission areas; claim 5 has separate dye layers spaced apart to correspond to each emission area; claims 6 and 7 detail whether the dye fills between the metal's top and the sidewall or extends over the black matrix itself. Claim 8 places a dye layer at the outermost side of the substrate in contact with the black matrix's side surface. These are the variants that let the applicant claim both a continuous dye sheet and islanded dye without amending the independent claim.

Where the claim lands in the CPC map

The classification places the filing squarely in organic light-emitting display structure, not in a UI or driving-scheme class. Its listed CPC groups include H10K 59/8792 and H10K 59/879 — optical arrangements and light-extraction structures for OLED devices — alongside H10K 59/40 for OLEDs integrated with touch or other sensing, H10K 59/873 for encapsulation, and H10K 59/1201 for pixel-defining structure. That distribution is itself a reading aid: the claim is examined as OLED panel architecture — how absorbing, light-extraction and touch layers are arranged on the panel — which is consistent with independent claims whose limitations are all about the ordering and geometry of films, not about materials chemistry or circuits.

The filing sits inside a dense same-day LG Display cluster in the same CPC neighborhood, which is where a landscape reader would place it. US20260190831A1, from the same inventor team, claims organic dye patterns on the touch sensor whose side surfaces refract light toward the opening — a companion classified in H10K 59/8792. US20260190834A1 claims a light-guide member with a visible-light-absorbing layer; US20260190806A1 claims optical members with light-blocking patterns; US20260190815A1 claims a dual-refractive-index optical improvement layer; and US20260190818A1 claims a varied planarization height to reduce external-light reflectance. Each is a separate pending application with its own claims; they are cited here as neighbors sharing the anti-reflection and light-extraction CPC space, not as part of the hero claim's scope.

What the hero application claims is legible and specific: an OLED whose black matrix, in-opening metal patterns, and organic dye layer are ordered on top of the touch sensor, recited across three independent claims that fix the stack, the same-layer relationship, and the metal cross-section. This brief identifies the claimed structure and its CPC coordinates and characterizes the scope no further than the language supports. And it repeats the one procedural fact that governs everything above — US20260190833A1 is a pending, published application, disclosed and now searchable, but not yet examined to grant.
