Display device and method of controlling the same
First Claim
1. A display device comprising:
- a transparent display panel;
an imaging device disposed at a light-exiting side of the transparent display panel; and
a light adjusting cover disposed at a side of the transparent display panel opposite to the light-exiting side, the transparent display panel being disposed such that a distance between the transparent display panel and the imaging device is less than or equal to a focal length of the imaging device;
wherein the imaging device is configured to image a picture displayed on the transparent display panel at a side of the transparent display panel away from the imaging device; and
wherein the light adjusting cover is switchable between a light-transmitting state and a light-shaded state, and is capable of covering a viewing field of human eyes;
wherein the imaging device comprises a liquid lens, and the liquid lens comprises a transparent housing and a conductive aqueous solution and an insulation solution that are packaged in the transparent housing;
a hydrophobic layer being provided on an inner wall of the transparent housing and incompletely covering the transparent housing;
wherein the conductive aqueous solution and the insulation solution have different refractive indexes and are not soluble in each other.

Abstract
A display device and a method of controlling the same realizes a virtual reality display and an augmented reality display. The display device includes a transparent display panel, an imaging device disposed at a light-exiting side of the transparent display panel, and a light adjusting cover disposed at a side of the transparent display panel away from the light-exiting side. The transparent display panel is disposed within a focal length of the imaging device. The imaging device is configured to image pictures displayed on the transparent display panel at a side thereof away from the imaging device. The light adjusting cover is switchable between a light-transmitting state and a light-shaded state, and is capable of covering a viewing field of human eyes. The display device can perform the virtual reality display or the augmented reality display.
