Purpose. The patent addresses narrow-border flexible display panels. In pad bonding, a bendable region between a display region and a binding region of a panel is bent toward the back side of the display region so the binding region sits behind the display region, reducing border width. The disclosure aims to improve signal transmission through that bendable region.

Plain-language scope. A display panel has a panel main body with a display region, a bendable region, and a binding region. Signal transmission lines run from the display region to the binding region through the bendable region. An enhancement layer in the bendable region includes an electrode layer with at least one auxiliary electrode; each auxiliary electrode corresponds to, and is electrically connected to, one signal transmission line, with different auxiliary electrodes corresponding to different lines. In embodiments, an auxiliary electrode connects to its signal transmission line via an anisotropic conductive adhesive to form parallel conductive channels. The enhancement layer may include a flexible substrate (e.g., polyimide) on a side of the electrode layer distal to the panel main body. The disclosure also describes arrangements of auxiliary electrodes and signal transmission lines whose length-direction virtual extension lines intersect at a common convergence point on a reference line, and electrode materials such as single-layer Mo or Ag, Mo/Al/Mo, or Ti/Al/Ti. A second aspect covers a flexible display device comprising such a panel.

What the excerpt does not establish. The supplied text lists classifications (e.g., G06F1/1652, H10K59/1315) and definitions but does not provide the full claims, the complete description, drawing content (e.g., FIG. 1), a prior-art discussion, cited references, or an examination history. It therefore does not establish the exact claim scope, validity, or the figures' details beyond the captions quoted above.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.

PTAB challenges

AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
