Abstract

A bezel-less display is disclosed that includes an electronic display device and a cover. The electronic display device has an image-displaying portion and another portion adjacent the image-displaying portion along at least one side. The cover is positioned adjacent the electronic display device and includes a first portion positioned adjacent the image-displaying portion of the display device and a second portion positioned adjacent the other portion of the display device. The optical properties of the first and second portions of the cover are selected to present an appearance of a uniform cover without a bezel when the display device is not displaying an image. The optical properties of the first portion are also selected to transmit images displayed on the image-displaying portion. Preferably, the optical properties of the second portion are selected to mask the other portion of the display device. A secondary display device may also be provided that presents an image, such as a logo, independently of whether the other or main electronic display device is displaying an image.

Claims

1. An electronic display without a bezel, comprising:

an electronic display device comprising an image-displaying portion and another portion adjacent the image-displaying portion along at least one side, the image-displaying portion selectively projecting light to generate images and not projecting light, and the other portion not projecting light and not generating images; and

a cover positioned adjacent the electronic display device, the cover including a first portion having first optical properties positioned adjacent the image-displaying portion of the display device and a second portion having second optical properties positioned adjacent the other portion of the display device, the first optical properties of the first portion of the cover being such that the first portion substantially transmits light projected from the image-displaying portion, and the first optical properties of the first portion and the second optical properties of the second portion being such that the cover presents an appearance of a uniform cover without a bezel when light is not projected from the image-displaying portion.

2. The electronic display of claim 1 wherein, the second portion comprises an opaque material comprising optical properties matched to those of the first portion so that the first and second portions present the appearance of a uniform cover without a bezel when light is not projected from the image-displaying portion.

3. The electronic display of claim 1 wherein, the second portion comprises an opaque material, and the opaque material and the first portion comprise color values such that the first and second portions present the appearance of a uniform cover without a bezel when light is not projected from the image-displaying portion.

4. The electronic display of claim 1 wherein, the second portion comprises an opaque material and the first portion comprises tinting that provides an appearance of the first portion that matches an appearance of the opaque material and which together present the appearance of a uniform cover without a bezel when light is not projected from the image-displaying portion.

5. The electronic display of claim 1 wherein, the cover comprises a plastic, light-transmitting sheet and the second portion comprises an opaque layer on the plastic sheet, the opaque layer and the plastic sheet in the first portion of the cover together presenting the appearance of a uniform cover without a bezel when light is not projected from the image-displaying portion.

6. An electronic display without a bezel, comprising:

an electronic display device comprising an image-displaying portion and another portion adjacent the image-displaying portion along at least one side, the image-displaying portion selectively projecting light to generate images and not projecting light, and the other portion not projecting light and not generating images; and

a cover positioned adjacent the electronic display device, the cover including a first portion having first optical properties positioned adjacent the image-displaying portion of the display device and a second portion having second optical properties different from the first optical properties positioned adjacent the other portion of the display device, the first optical properties of the first portion of the cover being such that the first portion substantially transmits light projected from the image-displaying portion, and the first optical properties of the first portion and the second optical properties of the second portion being such that the cover presents an appearance of a uniform cover without a bezel when light is not projected from the image-displaying portion.
