Abstract

The present invention discloses a transparent display, comprising a first display, comprising a plurality of first display regions and a plurality of transparent regions alternately arranged along a first direction; a second display, comprising a plurality of second display regions and a plurality of second transparent regions which are alternately located along the first direction, and the second display is laminated with the first display and located at one side of the first display in an image display direction, and the vertical projections of the second display regions on the first display completely coincide with the first transparent regions, and the vertical projections of the second transparent regions on the first display completely coincide with the first transparent regions; a camera shooting module; a signal process module.

Claims

1. A transparent display in an enclosed environment, where a user of the transparent display is, comprising:

a first display, and the first display comprises a plurality of first display regions and a plurality of transparent regions alternately arranged along a first direction;

a second display, the second display is laminated with the first display and located at one side of the first display in an image display direction, and the second display comprises a plurality of second display regions and a plurality of second transparent regions which are alternately located along the first direction, and the second transparent regions are employed to transmit the light emitted by the first display to human eyes of the user;

vertical projections of the first display regions on the second display completely coincide with the second transparent regions, and vertical projections of the first transparent regions on the second display completely coincide with the first transparent regions;

a camera shooting module, and the camera shooting module is employed to shoot an environment image to form an environment image signal of an outdoor environment, which is not the enclosed environment where the user of the transparent display is;

a signal process module, and the signal process module receives the environment image signal and converts the same into a first display image signal, and the first display receives the first display image signal and shows the same in the first display regions;

the signal process module further receives a picture image signal and converts the same into a second display image signal, and the second display receives the second display image signal and shows the same in the second display regions to respectively show the environment image of the outdoor environment, which is not the enclosed environment and the picture image of the transparent display in the enclosed environment in a form of an individual layer display with the first display and the second display laminated with the first display, wherein the user watches the environment image signal of the outdoor environment shown by the first display and the picture image signal shown by the second display at the same time.

2.
