Abstract
An optical stack includes a front major surface and a rear major surface defining a peripheral edge. A reflective element is located between the front and rear major surfaces and configured to modify the transmission of light. A scattering layer is located between the front major surface and the reflective element. The scattering layer is switchable between a transmissive mode and a scattering mode. In the transmissive mode, light reflected from or transmitted through the reflective element is substantially unchanged. In the scattering mode, light reflected from or transmitted through the reflective element is substantially scattered.

An optical stack comprising:
- a front major surface and a rear major surface defining a peripheral edge;
- a reflective element located between the front and rear major surfaces and configured to modify the transmission of light;
- and
- a scattering layer located between the front major surface and the reflective element, the scattering layer switchable between a transmissive mode wherein light reflected from or transmitted through the reflective element is substantially unchanged, and a scattering mode wherein light reflected from or transmitted through the reflective element is substantially scattered.
An optical stack selectively bi-directionally reflective, the optical stack comprising:
- a front major surface and a rear major surface defining a peripheral edge;
- a switchable reflective element located between the front and rear major surfaces and configured to selectively reflect the transmission of light from the front major surface in a first state and selectively transmit the transmission of light from the front major surface in a second state;
- and
- a scattering layer located between the front major surface and the reflective element, the scattering layer switchable between a transmissive mode wherein light reflected from or transmitted through the reflective element is substantially unchanged, and a scattering mode wherein light reflected from or transmitted through the reflective element is substantially scattered.
An optical stack comprising:
- a front major surface and a rear major surface defining a peripheral edge;
- a reflective element located between the front and rear major surfaces and configured to modify the transmission of light;
- and
- a segmented scattering layer located between the front major surface and the reflective element including a plurality of scattering segments, each scattering segment in the scattering layer individually switchable between a transmissive mode wherein light reflected from or transmitted through the reflective element is substantially unchanged, and a scattering mode wherein light reflected from or transmitted through the reflective element is substantially scattered.
