Abstract
A transparent display device and method of forming such device. The transparent display device includes a substrate, wherein the substrate allows greater than 50% of incident light to pass through the substrate. The device also includes a plurality of pixels formed on the substrate, wherein the pixels are formed of an adjustable permittivity material wherein the adjustable permittivity material exhibits a change in permittivity upon the application of a voltage and is normally transparent. The device further includes interconnects operatively coupled to the adjustable permittivity material in each pixel, wherein the interconnects are configured to provide voltage to the adjustable permittivity material.
Claims25
A transparent display device, comprising:
- a substrate, wherein said substrate allows greater than 50% of incident light to pass through said substrate;
- a plurality of pixels formed on said substrate, wherein said pixels are formed of an adjustable permittivity material wherein said adjustable permittivity material exhibits a change in permittivity upon the application of a voltage and is normally transparent;
- and
- interconnects operatively coupled to said adjustable permittivity material in each pixel, wherein said interconnects are configured to provide said voltage to said adjustable permittivity material.
A method of forming a transparent display device comprising:
- forming a plurality of pixels on a substrate by depositing an adjustable permittivity material in discrete sections on said substrate wherein said substrate allows greater than 50% of incident light to pass through said substrate and said adjustable permittivity material is normally transparent;
- depositing horizontal and vertical interconnects on said substrate, wherein said interconnects are operatively coupled to the adjustable permittivity material of said pixels.
A method of forming an image on a transparent display, comprising:
- generating an image to be displayed on a transparent display with a processor, wherein said display allows greater than 50% of incident light having a wavelength in the range of 380 nm to 700 nm to pass through said display;
- dividing an image into pixels with said processor;
- determining the color and transparency of each pixel by said processor;
- determining a voltage to apply to each of said pixels based on measured relationships of strain to permittivity for an adjustable permittivity material forming said pixels;
- applying a voltage to the adjustable permittivity material of one or more of said pixels by said processor;
- and
- altering the permittivity of said adjustable permittivity material.
A system of forming an image on a transparent display, comprising one or more storage mediums having stored thereon, individually or in combination, instructions that when executed by one or more processors result in the following operations comprising:
- generating an image to be displayed on a transparent display with a processor, wherein said display allows greater than 50% of incident light having a wavelength in the range of 380 nm to 700 nm to pass through said display;
- dividing an image into pixels with said processor;
- determining the color and transparency of each pixel by said processor;
- determining a voltage to apply to each of said pixels based on measured relationships of strain to permittivity for an adjustable permittivity material forming said pixels;
- applying a voltage to the adjustable permittivity material of one or more of said pixels by said processor;
- and
- altering the permittivity of said adjustable permittivity material.
