FIELD

The present disclosure generally relates to holographic glass, and more specifically to holographic glass for screen color matching.

BACKGROUND

A typical display screen on a device does not occupy the entire surface of the device. As such, the boundary between a display screen and the non-displaying portions of the device may be readily visible. A technique to reduce the visibility of this boundary includes coloring the non-displaying portions of the device the same color as the display screen (i.e., pigment matching). However, because display screens typically have a periodic micro-structure (e.g., a pixelated structure), the color of the display screen may be dependent on the angle at which a viewer is looking at the display screen. The non-displaying portions of the device may be unable to match this angular color dependence of the display screen, resulting in a readily visible boundary between the display screen and the non-displaying portions of the device. Accordingly, there is a need for better color integration between the displaying portions of a device and the non-displaying portions of the device.

BRIEF SUMMARY

Exemplary systems and devices that may reduce or eliminate the visibility of a boundary between displaying portions of the system and non-displaying portions of the system are disclosed. An exemplary system includes a display screen including a plurality of pixels forming a first periodic structure and a frame surrounding at least a portion of the display screen. The frame may include a holographic structure having a second periodic structure. The first pitch of the first periodic structure may be within 0.5 percent to 20 percent of the second pitch of the second periodic structure.
