Visibly opaque and near infrared transparent display border with underlying encoded pattern
A display may include a viewing area and a border about the viewing area. The border is visibly opaque and near infrared transparent. An encoded pattern underlies the border.
1. A display comprising:
a viewing area, wherein the viewing area corresponds to an image layer;
an encoded pattern embedded in a dot film, wherein the dot film is adhered to the image layer;
a sensor glass adhered to the dot film, opposite the image layer; and
a border about the viewing area, the border being visibly opaque and near infrared transparent and adhered to the sensor glass opposite the dot film.
2. The display of claim 1 , wherein the encoded pattern continuously extends from within the viewing area to beneath the border.
3. The display of claim 2 , wherein the encoded pattern extends at least 5 mm beyond the viewing area beneath the border.
4. The display of claim 1 , wherein the encoded pattern extends in the viewing area, the display further comprising a touch sensor in the viewing area.
5. The display of claim 1 , wherein the encoded pattern contains positional information readable by an infrared emitter/receiver of an electrical optical pen to indicate a position of the electro optical pen.
6. The display of claim 5 , wherein the border comprises:
a visibly transparent layer; and
a visibly opaque, near infrared transparent layer between the visibly transparent layer and the encoded pattern beneath the border.
7. The display of claim 1 , wherein the border comprises:
a visibly transparent layer; and
a visibly opaque, near infrared transparent layer between the visibly transparent layer and the encoded pattern beneath the border.
8. The display of claim 1 , further comprising a graphic on the border over the encoded pattern underlying the border.
9. The display of claim 8 , wherein the graphic comprises a visibly opaque, near infrared transparent layer.
10. The display of claim 8 , wherein the graphic indicates an input selection corresponding to a graphical user interface within the viewing area, wherein the input selection is adjacent to the viewing area within the border area coinciding with the encoded pattern underlying the border proximate the graphic.
11. The display of claim 1 , wherein encoded pattern comprises near infrared reflective dots over a near infrared absorptive background.
12. The display of claim 1 , wherein encoded pattern comprises near infrared absorptive dots over a near infrared reflective background.
13. A method comprising:
presenting an image in a viewing area of display, wherein the viewing area corresponds to an image layer;
reflecting near infrared wavelengths of light through the border of the viewing area from an encoded pattern beneath the border, wherein the encoded pattern is embedded in a dot film and the dot film is adhered to the image layer and a sensor glass opposite the image layer; and
blocking visible wavelengths of light that impinge a border of the viewing area of the display, wherein the border of the viewing area is adhered to the sensor glass opposite the dot film.
14. The method of claim 13 , wherein the near infrared wavelengths of light are reflected from the encoded pattern through the border area of the viewing area to an input pointer while the input pointer is in contact with the viewing area of the display.
15. A display comprising:
a viewing area, wherein the viewing area corresponds to an image layer;
an encoded pattern embedded in a dot film, wherein the dot film is adhered to the image layer;
a touch sensor in the viewing area, wherein the touch sensor corresponds to a sensor glass adhered to the dot film, opposite the image layer; and
a border about the viewing area, the border being visibly opaque and near infrared transparent and adhered to the sensor glass opposite the dot film.
