US Patent 7636146: Summary

• Title: Electro-optical panel, system with terminals having different corresponding characteristics
• Current Assignee: 138 East LCD Advancements Ltd
• Inventor: Shin Fujita
• Filing Date: August 6, 2004
• Issue Date: December 22, 2009
• Abstract: The patent describes a liquid crystal panel with input terminals grouped into first, second, and third categories. Driving signals are supplied to the first and third terminal groups, while image signals are supplied to the second. The key innovation is that the driving signals contain higher frequency components than the image signals, and consequently, the input terminals for the driving signals (first and third groups) have a larger area than those for the image signals (second group). This larger area reduces contact resistance, preventing the driving signals from becoming distorted or "dull."

Plain-Language Overview of Independent Claims:

• Independent Claim 1: This claim describes an electro-optical display panel featuring data lines, scanning lines, and pixels at their intersections. It includes dedicated input terminals for scanning line clock signals and image signals. A scanning line drive circuit uses the clock signal to control the scanning lines, and a general drive circuit manages pixel grayscale based on both clock and image signals. The panel also has power source terminals. A key aspect is that the clock signal input terminals are larger than the image signal input terminals, and the power source terminals are at least as large as the clock signal input terminals. Furthermore, multiple power, clock, and image signal terminals are arranged in a line on the substrate, with the spacing between adjacent clock signal terminals being a whole-number multiple of the spacing between adjacent image signal terminals.
• Independent Claim 10: This claim details an electro-optical panel built on a first substrate, comprising data lines, scanning lines, and pixels. It includes clock-signal and image-signal input terminals, both connected to an external mounting member (e.g., a flexible substrate) via an anisotropic conductive film (ACF). These terminals are located along one side of the first substrate. Image signals are supplied simultaneously to all data lines from an external data drive circuit. The panel also has a scanning-line drive circuit on the first substrate, synchronized by the clock signal. The core of this claim is that the clock-signal input terminal makes a larger contact area with its corresponding wiring on the mounting member (through the ACF) than any individual image-signal input terminal makes with its wiring.
• Independent Claim 23: This claim describes an electro-optical panel on a substrate, including data lines, scanning lines, pixels, a clock signal input terminal, and an image signal input terminal, all integrated onto the substrate. A scanning line drive circuit outputs signals to the scanning lines. A separate mounting member is connected to this substrate. This mounting member has a first wiring connected to the clock signal input terminal and a second wiring connected to the image signal input terminal. The claim emphasizes that the contact area between the clock signal input terminal and its first wiring on the mounting member is larger than the contact area between any individual image signal input terminal and its second wiring.

CAFC 2026 Dockets:
A search for "US7636146 CAFC dockets 2026" did not yield any specific dockets directly mentioning US7636146 in the U.S. Court of Appeals for the Federal Circuit for the year 2026. While the patent's Google Patents page indicates ongoing District Court and PTAB litigation (some from 2025 and 2026), there is no authoritative information confirming an appeal to the CAFC specifically for this patent in 2026 at this time.
