Description

imaging display device This specification relates to an image display device. More specifically, it relates to an image display device for a vehicle or an image display device for an advertisement that displays a pop-up image together with a background image. An imaging display device can be implemented to display multiple images superimposed on each other. In this regard, it is necessary to display a pop-up image to focus the user's attention on a background image. Popup videos that capture the user's attention can be applied to outdoor advertising signs to enhance advertising effectiveness. Additionally, these attention-grabbing popup videos can be utilized on vehicle dashboards and implemented to display popup videos upon the detection of in-vehicle events. However, there is no presentation of a specific structure for an optical structure for implementing a video display device that displays a pop-up video to focus the user's attention on a background video. Meanwhile, a dihedral corner reflector array (DCRA) can be utilized as an optical structure for implementing a video display device. Optical structures utilizing a dihedral corner reflector array (DCRA) not only increase the system volume but also have low resolution, resulting in low image quality and brightness, and a narrow viewing angle. In addition, a micro lens array (MLA) can be utilized as an optical structure for implementing image display devices. Optical structures utilizing a micro lens array (MLA) not only increase system volume but also result in low image brightness and quality. Therefore, there is a need to implement an image display device that can reduce the volume of the optical system while maintaining image quality and viewing angle characteristics above a certain level.
