Abstract: A display device includes a display panel and a touch sensing unit on the display panel. The touch sensing unit comprises a first conductive pattern on the display panel, an insulating layer covering the first conductive pattern, and a second conductive pattern on the insulating layer. This second conductive pattern partially crosses the first conductive pattern and has a thickness greater than that of the first conductive pattern.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a display device featuring a display panel and a touch sensing unit mounted on it. The touch sensing unit includes a first conductive pattern, an insulating layer that covers the first pattern, and a second conductive pattern on top of the insulating layer. A key aspect is that the second conductive pattern partially overlaps the first conductive pattern, and importantly, the second conductive pattern is thicker than the first conductive pattern.

• Claim 12: This claim also details a display device with a display panel and a touch sensing unit. Here, the display panel is specifically defined as having a base layer, a circuit layer, an organic light-emitting device layer, and a thin film encapsulation (TFE) layer, all stacked sequentially. The first conductive pattern of the touch sensing unit is directly on this TFE layer. The insulating layer covering the first conductive pattern has a specific stepped structure: a first part above the first conductive pattern (and away from the TFE layer), a second part directly touching the TFE layer, and a third part connecting these first and second parts. Similar to Claim 1, the second conductive pattern is on the insulating layer, partially crosses the first conductive pattern, and is thicker than the first conductive pattern.

• Claim 18: This claim presents a display device with a display panel and a touch sensing unit, similar to Claim 1, where the second conductive pattern is thicker than the first. However, Claim 18 further specifies the internal structure of the first conductive pattern. It states that the first conductive pattern is a triple-layer structure, comprising a first conductive layer, a second conductive layer on the first, and a third conductive layer on the second. The second conductive layer in this stack has lower electrical resistivity than both the first and third conductive layers, and its thickness is greater than both the first and third conductive layers.

CAFC 2026 Dockets:
A review of the U.S. Court of Appeals for the Federal Circuit (CAFC) scheduled cases for May 2026 does not show any cases specifically mentioning patent US10541279. While the patent's Google Patents page indicates "Family has litigation" including a PTAB case IPR2025-01476 and a US case filed in the Texas Eastern District Court, no specific CAFC dockets for 2026 related to this patent were found in the provided search results.
