- Publication/Filing Date: Published: June 11, 2015; Filed: December 9, 2014.
- Brief Description: This patent application describes a display device including a display panel and a touch sensing unit. The touch sensing unit has a first electrode layer and a second electrode layer, which may include transparent conductive materials or metal meshes. The application discusses touch sensor patterns, insulating layers between them, and methods to suppress mutual interference between display signals and touch signals. It also mentions flexible display devices and various arrangements of touch electrodes.
- Potential Anticipated Claim(s) of US10541279: This reference broadly describes display devices with integrated touch sensing units comprising multiple conductive patterns and insulating layers (e.g., claims 1, 14, 15). Depending on the specifics of the disclosed electrode and insulating layer structures, it could potentially anticipate aspects of claims describing a display device with a display panel and a touch sensing unit on the display panel, where the touch sensing unit includes a first conductive pattern, an insulating layer covering the first conductive pattern, and a second conductive pattern on the insulating layer, partially crossing the first conductive pattern. However, the critical inventive feature of US10541279, relating to the thickness of the second conductive pattern being greater than the first to prevent cracking, would need to be explicitly disclosed or inherently present to be a direct anticipation of claims incorporating this specific thickness relationship (e.g., claims 1, 4, 14).

- Publication/Filing Date: Granted: December 20, 2016; Filed: July 28, 2015.
- Brief Description: This patent describes a display device including a display panel, a touch electrode layer, and an encapsulation layer. It focuses on the structure of touch electrodes that are configured to minimize light interference while maintaining touch sensitivity. The touch electrodes can be formed of a metal layer and can include mesh patterns. The patent also discusses transparent conductive layers and buffer layers.
- Potential Anticipated Claim(s) of US10541279: Similar to US20150160759A1, this patent generally describes display devices with integrated touch electrode layers (e.g., claims 1, 14, 15 of US10541279). Its discussion of metal layers and mesh patterns for touch electrodes could be relevant to the structural details of the conductive patterns in US10541279 (e.g., claims 10, 11). However, without explicit disclosure of the specific thickness differential between the first and second conductive patterns and the problem/solution of preventing cracking/shorts due to this differential, it would likely not anticipate the claims of US10541279 that focus on this critical feature (e.g., claims 1, 4, 14).

- Publication/Filing Date: Granted: April 4, 2017; Filed: May 2, 2016.
- Brief Description: This patent describes a display device with a touch sensing unit having first and second touch electrodes. The first touch electrodes include sensing patterns and connection parts, while the second touch electrodes include sensing patterns. An insulating layer separates the first and second touch electrodes. The invention addresses reducing resistance of sensing patterns without increasing thickness or reducing aperture ratio.
- Potential Anticipated Claim(s) of US10541279: This patent describes a touch sensing unit with first and second touch electrodes separated by an insulating layer, which is a foundational aspect of US10541279 (e.g., claims 1, 14, 15). The focus on reducing resistance and patterns could relate to the mesh lines in US10541279 (e.g., claim 11). However, the specific inventive concept of US10541279, concerning the relative thicknesses of the first and second conductive patterns to prevent cracking of the insulating layer, is not immediately apparent from the abstract of US9612662B2. Therefore, it would not directly anticipate claims that specifically rely on this thickness difference (e.g., claims 1, 4, 14).

- Brief Description: This patent relates to a display device with a touch screen panel. It discloses touch electrodes including first and second touch electrodes, and a dielectric layer therebetween. The touch electrodes are made of a transparent conductive material or a metal wire. The invention aims to improve touch detection sensitivity and reduce the resistance of the touch electrodes.
- Potential Anticipated Claim(s) of US10541279: Similar to the other cited art, this patent discloses a display device with a touch screen panel having first and second touch electrodes and a dielectric layer (insulating layer) between them (e.g., claims 1, 14, 15 of US10541279). The use of metal wires for electrodes could be relevant to the conductive patterns. However, there is no explicit mention in the abstract of the specific thickness differential between the conductive patterns and its purpose in preventing insulating layer cracking, which is a key distinguishing feature of US10541279 (e.g., claims 1, 4, 14).

- Publication/Filing Date: Granted: February 16, 2016; Filed: July 16, 2012.
- Brief Description: This patent describes a flexible display apparatus including a flexible display and a touch sensor panel. The touch sensor panel has first and second electrodes and an insulating layer between them. The invention is concerned with improving touch sensing performance and durability for flexible displays, particularly regarding the materials and arrangement of the electrodes and insulating layer.
- Potential Anticipated Claim(s) of US10541279: This patent broadly covers flexible display devices with touch sensor panels, including first and second electrodes and an insulating layer (e.g., claims 1, 14, 15 of US10541279, especially if US10541279 is applied to flexible displays as indicated in its description). While it addresses durability for flexible displays, the specific solution of making the second conductive pattern thicker than the first to prevent cracking of the insulating layer as highlighted in US10541279's claims is not explicitly detailed in the abstract of US9262078B2. Therefore, it is unlikely to directly anticipate the claims focused on that specific thickness relationship (e.g., claims 1, 4, 14).

- Publication/Filing Date: Published: June 16, 2016; Filed: December 10, 2015.
- Brief Description: This patent application describes a display device comprising a display panel and a touch screen panel. The touch screen panel includes first and second electrodes and an insulating layer. The invention focuses on reducing or eliminating color shift in the display due to the touch screen panel and improving display quality.

- Potential Anticipated Claim(s) of US10541279: This reference also describes a display device with a display panel and a touch screen panel having first and second electrodes and an insulating layer (e.g., claims 1, 14, 15 of US10541279). While it addresses display quality issues, the primary inventive concept of US10541279 regarding the specific differential thickness of conductive patterns to prevent insulating layer cracking and shorts is not explicitly disclosed or suggested in the abstract of this reference. Therefore, it would not directly anticipate claims that specifically require this thickness difference (e.g., claims 1, 4, 14).

Summary of Potential Anticipation:

The cited prior art generally discloses the fundamental components of a display device with an integrated touch sensing unit, including first and second conductive patterns (touch electrodes) and an insulating layer separating them. These references broadly anticipate elements found in the independent claims of US10541279, such as "a display device including a display panel, and a touch sensing unit on the display panel, the touch sensing unit including 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, partially crossing the first conductive pattern" (e.g., claims 1, 14, 15).

However, the key distinguishing feature of US10541279, as stated in its abstract and claims, is that the second conductive pattern has a thickness that is greater than a thickness of the first conductive pattern, specifically to prevent cracking of the insulating layer and shorting. Claims 1, 4, 14, 15, and 16 explicitly include this thickness relationship. Without a clear disclosure in the cited prior art of this specific thickness differential and its technical effect on preventing insulating layer cracks, these claims would likely not be directly anticipated by the listed references. The detailed specifications for the multi-layer conductive patterns (e.g., claims 5-9, 17-20) and their specific material compositions (e.g., claims 9, 20) also represent additional layers of specificity that would need to be met by prior art for direct anticipation.To accurately identify the most relevant prior art for US patent 10541279, I need to consult the "Cited patents" or "References" section of its Google Patents page.
