Abstract

A display with illumination function, comprising: a display body, including a display screen; a support, have a top and a base, said top includes at least one of the pivot member joint to one side of display body allow the display body to rotate freely; a light source disposed around the display screen; and a stand connected to the base of the support. When the surrounding environment has insufficient lighting for reading or using the display, the user can simply turn on the light source to illuminates the display screen and work area, without the needs of additional lamps or other lighting devices which can occupy extra desk space.

Claims

1. A display for an electronic device with additional illumination function comprising:

a display body including a display screen arranged to display images generated by the electronic device to a user;

a support having a top and a base, the top including at least one pivot member jointed to one side of the display body allowing the display body to rotate freely;

a plurality of light sources disposed on an exterior perimeter of the display screen in a symmetrical arrangement surrounding the display screen; and

a stand connected to the base of the support,

wherein the display screen has an exterior surface, the exterior surface including a layer of backlight film; and

wherein the backlight film is treated with mirror finish arranged to permit backlight to pass through the display screen toward the user when the display is turned on and reflect external light off the backlight film creating a mirror image when the display is turned off.

2. The display with additional illumination function as in claim 1, wherein each of the plurality of light sources is a point light source.

3. The display with additional illumination function as in claim 1, wherein each of the plurality of light sources is a tube light source.

4. The display with additional illumination function as in claim 2, wherein the point light source is a light-emitting diode, halogen light bulb or fluorescent light bulb.

5. The display with additional illumination function as in claim 3, wherein the tube light source is a light-emitting diode, halogen light bulb or fluorescent light bulb.

6. The display with additional illumination function as in claim 1, wherein the display screen is a liquid crystal display, a plasma display panel, or an organic light emission diode.

7. The display with additional illumination function as in claim 1, the mirror finish is coated by spray coating.

8. The display with additional illumination function as in claim 1, the mirror finish is coated by electroplating.

9. The display with additional illumination function as in claim 1, wherein the plurality of light sources is in addition to a source of illumination for the display screen for displaying images of the electronic device.

10. A display for an electronic device with additional illumination function comprising:

a display body including a display screen arranged to display images generated by the electronic device to a user;

a support having a Y-shaped top and a base, the Y-shaped top including two pivot members on each side jointed to two sides of the display body allowing the display body to rotate freely within the Y-shaped top;

a plurality of light sources disposed on an exterior perimeter of the display screen in a symmetrical arrangement surrounding the display screen; and

a stand connected to the base of the support,

wherein the display screen has an exterior surface, the exterior surface including a layer of backlight film; and

wherein the backlight film is treated with mirror finish arranged to permit backlight to pass through the display screen toward the user when the display is turned on and reflect external light off the backlight film creating a mirror image when the display is turned off.

11. The display with additional illumination function as in claim 10, wherein each of the plurality of light sources is a point light source.

12. The display with additional illumination function as in claim 10, wherein each of the plurality of light sources is a tube light source.

13. The display with additional illumination function as in claim 11, wherein the point light source is a light-emitting diode, halogen light bulb or fluorescent light bulb.

14. The display with additional illumination function as in claim 12, wherein the tube light source is a light-emitting diode, halogen light bulb or fluorescent light bulb.

15. The display with additional illumination function as in claim 10, wherein the display screen is a liquid crystal display, a plasma display panel, or an organic light emission diode.

16. The display with additional illumination function as in claim 10, the mirror finish is coated by spray coating.

17. The display with additional illumination function as in claim 10, the mirror finish is coated by electroplating.

18. The display with additional illumination function as in claim 10, wherein the plurality of light sources is in addition to a source of illumination for the display screen for displaying images of the electronic device.
