AI Technical Summary

Technical Problem

Existing floating display technology cannot flexibly adjust the size of the floating image, which requires the design of different optical systems for different user needs, consuming a lot of manpower and resources. Furthermore, large-size floating images suffer from severe distortion, high cost, and large thickness.

Method used

By employing a splicing display device, multiple floating sub-images are formed in the air through multiple display units and optical imaging modules. Adjacent sub-images are overlapped and spliced ​​to form a complete image. Large-size floating display is achieved using small-sized optical elements, reducing costs and thickness.

Benefits of technology

It enables flexible adjustment of floating displays of different sizes, reduces manufacturing costs and thickness, reduces reliance on large-size optical components, and improves the flexibility and thinness of the optical system.

Abstract

The present application relates to a tiled display device for a floating image and a multi-layer display apparatus comprising the same. The tiled display device comprises: a display module configured to emit display light constituting a target image, the display module comprising a plurality of display portions arranged at intervals along a y direction, wherein each display portion is configured to display a corresponding portion of the target image; and a plurality of optical imaging modules configured to receive the display light emitted from the display module to form a plurality of floating sub-images in air, wherein each optical imaging module has an object plane and an image plane, wherein each of the plurality of display portions is placed at the object plane of a corresponding optical imaging module of the plurality of optical imaging modules, and the display light emitted by each display portion presents a corresponding floating sub-image at the image plane through the corresponding optical imaging module, wherein the plurality of floating sub-images constitute a complete floating image of the target image, and adjacent floating sub-images of the plurality of floating sub-images have an overlapping tiled area and have the same image content in the tiled area.
