Abstract
A glass article including a spatial location encoding layer for use in a digital inking system, an associated electronic device, a method of making and a digital inking system are provided. The glass article utilizes a plurality of light converting regions disposed on the surface of the glass in a pattern encoding spatial location. The plurality of light converting regions are formed from an inorganic, environmentally stable material, such as alternating stacks of III-V compound materials.
Claims23
A glass article comprising:
- a glass layer comprising:
- a first major surface;
- a second major surface opposite the first major surface;
- and
- a plurality of light converting regions disposed on the first major surface of the glass layer, each of the plurality of light converting regions comprising:
- a layer of a first III-V compound;
- and
- a layer of a second III-V compound, wherein the first III-V compound is different from the second III-V compound;
- wherein the plurality of light converting regions are arranged in a pattern relative to the first major surface which encodes information indicating a spatial location of each light converting region along the first major surface of the glass layer.
An electronic display device configured for digital handwriting conversion, the electronic display device comprising:
- a housing;
- a cover glass layer supported by the housing, the cover glass layer including an outward facing major surface and an inward facing major surface;
- a plurality of light converting regions located below the cover glass layer, the plurality of light converting regions arranged in a pattern relative to the outward facing major surface which encodes information indicating a spatial location of each light converting region relative to the outward facing major surface of the cover glass layer;
- wherein the plurality of light converting regions are formed from an inorganic material that absorbs light having a wavelength less than 400 nm and that emits light having a peak wavelength greater than 650 nm in response to the absorbed light;
- and
- wherein a region of the electronic display device within the housing surrounding the plurality of light converting regions is not hermetically sealed such that the housing includes at least one pathway for oxygen to traverse into the housing to reach the plurality of light converting regions.
A method of forming an article for a digital inking system comprising:
- depositing a layer of light converting inorganic material onto a major surface of a sheet of transparent material in a pattern which encodes information indicating a spatial location of each region of the pattern along the major surface of the sheet of transparent material;
- wherein the major surface of the sheet of transparent material and the layer of light converting inorganic material are exposed to oxygen during or following the depositing step, wherein the light converting inorganic material is oxygen insensitive such that exposure to oxygen does not degrade the light converting inorganic material.
