PATENTS

Extensive patent portfolio

Epson has a long history of developing see-through smart glasses and has been granted many important patents for optical engine module technology.
Each patent application is planned and submitted to ensure the security of key concepts for optical engine technology development.

US9829709

Technical Field

The present invention relates to a virtual image display apparatus which provides video formed by an image display element or the like to an observer, and in particular, to a virtual image display apparatus which is suitable for a head-mounted display mounted to the head of the observer.

Abstract

A light guide member (10) includes three surfaces of a second surface (S12), a fourth surface (S14), and a fifth surface (S15) as two or more non-axisymmetric curved surfaces, and a projection lens (30) includes a lens surface (31 a) as a non-axisymmetric aspheric surface. With this, on the light guide member side, even when there is a shape constraint that the first surface (S11) or the third surface (S13) which is a surface contributing to light guide is a flat surface, and correction of asymmetric aberration is limited, it becomes possible to perform sufficient aberration correction as the whole of an optical system including the projection lens. Therefore, the virtual image display apparatus can have a wide viewing angle and high performance, and can be made small and lightweight

US9269924

Technical Field

The present invention relates to electro-optical apparatuses, manufacturing methods for such electro-optical apparatuses, and electronic devices.

Abstract

An electro-optical apparatus includes a first pixel and a second pixel. The first pixel and the second pixel include a reflective layer, an insulating layer, a functional layer, and an opposing electrode. The insulating layer includes a first insulating layer, a second insulating layer having a first opening, and a third insulating layer having a second opening. A first pixel electrode is provided on the first insulating layer in the first opening. A second pixel electrode is provided on the second insulating layer.

US10247945

Technical Field

The present invention relates to a virtual image display apparatus that presents a viewer with video images formed by an image display apparatus (video device).

Abstract

In a projection system, providing a stop that forms an opening that is symmetric with respect to a first flat plane including the projection system optical axis and a first axis that extends in parallel to the first direction and intersects the projection system optical axis but asymmetric with respect to a second flat surface including the projection system optical axis and a second axis that extends in parallel to the second direction and intersects the projection system optical axis allows appropriate light adjustment at the stop even when pencils of light from the points in a video device exit at different angles along a second direction, whereby high-quality video images can be provided with the size of an optical system further reduced and therefore the size of an overall virtual image display apparatus reduced.
