Stereoscopic Display Optics With Reflective Lens-Black Matrix Boundaries

The patent converts the harmful light loss at lens boundaries into a beneficial effect by introducing a light reflection layer. This layer captures light that would otherwise be lost at the boundaries between lenses and black matrices, and redirects it toward the front of the display device. The reflection layer transforms the harmful light absorption into useful light contribution, thereby increasing overall luminance and converting energy loss into energy utilization.

The light reflection layer acts as an intermediary element between the lenses and the black matrices. It is positioned at the boundaries where light loss occurs, serving as a mediator that intercepts lost light and redirects it toward the viewing area. This intermediary layer prevents direct contact between the lens and black matrix boundaries, allowing light management without interfering with the primary functions of the lenses and black matrices.

The light reflection layer is applied selectively only at the critical boundaries between lenses and black matrices where light loss occurs, rather than uniformly across the entire display device. This localized application targets the specific problem areas, providing the necessary light reflection function only where needed. The reflection layer's lower refractive index is specifically optimized for its boundary location, creating local quality enhancement without unnecessary complexity elsewhere in the device.

The patent employs a composite structure by integrating the light reflection layer with the existing lens and black matrix components. The reflection layer is formed as a distinct material phase with different optical properties (lower refractive index) than the surrounding lens material. This composite approach allows each component to maintain its primary function while the combined structure provides the additional light reflection capability, achieving complexity only where functionally necessary.
