AI Technical Summary

Benefits of technology

The patent text describes a technology that allows for the modeling and recording of light propagation in a detector. This knowledge of light propagation has several advantages, including the ability to modify the observer position after recording an image. By changing the distance to the lens or the image plane, hidden objects can be made visible. The modification of observer position is particularly useful in motion capture and three-dimensional video recordings as it avoids the cardboard effect. Additionally, the text describes the use of a combination of electrically conductive polymers and metal layers to provide thin, transparent, and highly electrically conductive layers for the second electrode.

Problems solved by technology

A technically complex driving electronics of the generating pixels and the displaying pixels is required.
