Company patents
Shanghai AVIC OPTO Electronics Co., Ltd.
Shanghai AVIC OPTO Electronics Co., Ltd. shows a surprising shift in its patent strategy, with a strong re-emergence in Display Drivers, which saw a remarkable +300.0% YoY growth so far in 2026, now constituting 27.9% of its portfolio. This comes despite a significant decline in other semiconductor-related areas like Semiconductor Packaging & Encapsulation and Chip-to-Chip Interconnect (Bonding, Bumps), both experiencing a -100.0% YoY drop in 2026, indicating a focused pivot towards display technologies.

Techniques for driving electrophoretic displays, including managing remnant voltage, optimizing particle movement, and specific addressing pulse schemes to improve optical quality and update speed.
Packaging technologies where bare dies are embedded within a mold compound or substrate cavity, and then interconnected using redistribution layers (RDLs) for fan-out or compact integration, often avoiding through-silicon vias in the chips themselves.
Design and implementation of circuits and layouts for driving individual pixels or rows/columns of pixels, including gate drivers, data drivers, pixel driving circuits, and their integration onto the display substrate, often in non-display regions.
Innovations in backlight units, optical films, and light management structures to enhance display performance, uniformity, viewing experience, or specific functionalities like touch.
Methods and structures for integrating and enclosing electronic components into compact, multi-functional modules, often involving embedded components, multi-layer substrates, and electromagnetic shielding for performance and miniaturization.
Techniques and circuits for optimizing power consumption, voltage stability, and energy efficiency in display panels, often involving dynamic voltage scaling, duty cycle control, or remnant voltage management.
Methods and circuits for coordinating the timing of display signals, data transmission, and control signals across various display components, ensuring proper image rendering and efficient operation.
Design and manufacturing techniques for incorporating antenna structures directly into electronic devices, product housings, or materials, often under constraints of space, aesthetics, or environmental factors.
Systems and methods for electronically steering or shaping antenna beams by controlling the phase and amplitude of signals fed to individual elements in an array, including calibration techniques and multi-antenna configurations.
Physical layout and material composition of individual pixels within a display panel, including active layers, electrodes, light-emitting elements (LEDs, OLEDs), and associated thin-film transistors (TFTs).
Antennas engineered to operate effectively across a wide continuous range of frequencies (broadband) or multiple distinct frequency bands, often requiring specific radiating element geometries or impedance matching circuits.
Manufacturing processes and material compositions for creating electronic circuits on flexible or conformable substrates, enabling novel form factors, enhanced durability, and new applications beyond rigid PCBs.
Development of novel materials and designs for bonding, sealing, and underfill applications, focusing on improving mechanical integrity, electrical performance, and preventing defects like cracks or delamination in chip-to-chip connections.
Technologies that create dynamic and interactive visual content for displays, including virtual/wearable systems, by generating overlays, replacing input streams, or merging real-time user actions with digital environments.
Miniaturized devices that manipulate small volumes of fluids (nanoliters to picoliters) through microchannels to perform laboratory functions like mixing, separation, reaction, and detection on a single chip.
Techniques and structures used to reduce unwanted electromagnetic coupling, scattering, or interference between multiple antennas, different frequency bands, or sensitive electronic components within a device.
Self-contained or modular devices designed to automate and integrate multiple steps of molecular diagnostic assays, from sample preparation to result interpretation, often for point-of-care or high-throughput applications.
Methods and compositions for identifying, quantifying, or characterizing specific biological molecules (e.g., nucleic acids, proteins, metabolites, antibodies) or microbial species, often for diagnostic, prognostic, or quality control applications.
