SEIKO EPSON CORPORATION patent applications published on April 4th, 2024

Summary of the patent applications from SEIKO EPSON CORPORATION on April 4th, 2024

SEIKO EPSON CORPORATION has recently filed patents for innovative technologies in piezoelectric substrates, light-emitting element structures, circuit board units, and image reading apparatuses.

- The piezoelectric substrate features a base body, electrode, and piezoelectric layer containing potassium, sodium, and niobium, with an integrated intensity ratio (IRIR) less than 0.086. This technology aims to improve piezoelectric performance for sensing technology, energy harvesting devices, and acoustic wave filters.

- The light-emitting element structure enhances light output efficiency by utilizing a resonance effect between reflective and semi-transmissive layers. This innovation benefits display screens, lighting systems, and optical communication devices.

- The circuit board unit ensures reliable grounding between boards in electronic devices, improving electrical performance and reducing electromagnetic interference. This technology has potential applications in various electronic products.

- The image reading apparatus accurately detects movement in a two-dimensional coordinate system while protecting the sensor with a cover. This technology offers improved accuracy in movement detection for document scanners, image capture devices, and medical imaging equipment.

Potential Applications:

• Sensing technology, energy harvesting devices, acoustic wave filters
• Display screens, lighting systems, optical communication devices
• Electronic devices, computers, smartphones
• Document scanners, image capture devices, medical imaging devices.
