Abstract
Flexible plastic screen for glasses, sunglasses or helmet faceshields with controlled light transmission based on applied electrical voltage. The screen consists of two transparent flexible conductive polymer electrodes disposed and an electrochromic layer disposed between them. The electrochromic layer is a homogeneous mixture of active electrochromic components dissolved in a polymer matrix. The electrochromic screen is operable to vary the light transmission of any wearable electro-optical devices, such as the glasses, for creating an effect of a blackout for augmented/virtual reality glasses.
Claims21
1-20. (canceled)
A wearable electro-optical device comprising:
- an electrochromic layer of active electrochromic components dissolved in a polymer matrix;
- a controller electrically coupled to the electrochromic layer and configured to apply a controlling voltage to the electrochromic layer in response to a received control command to vary light transmittance of the electrochromic layer;
- and
- a power source for supplying electrical power to the controller.
Virtual or augmented reality glasses comprising:
- (a) an electrochromic layer;
- (b) a controller electrically coupled to the electrochromic layer and configured to apply a controlling voltage to the electrochromic layer in response to a received control command to vary light transmittance of the electrochromic layer;
- and
- (c) a power source for supplying electrical power to the controller.
Sun glasses comprising:
- (a) an electrochromic layer;
- (b) a controller electrically coupled to the electrochromic layer and configured to apply a controlling voltage to the electrochromic layer in response to a received control command to vary light transmittance of the electrochromic layer;
- and
- (c) a power source for supplying electrical power to the controller.
