Abstract

According to the present invention, a MicroLED-based display device for sending an image to a projection area includes a projection device and a transmission element. The projection device emits imagelight based on a MicroLED. The transmission element includes a coupling-in component, a conveying layer and a coupling-out member. The projection device is arranged on the coupling-in component of the transmission element in a manner to align the image light. The coupling-in component receives and guides the image light transmission. The coupling-out component expands and outputs the image lightoutward. The image that enters the conveying layer from the coupling-in component is totally reflected to a light output component, and then is conveyed to the projection area. In addition, the present invention provides a MicroLED-based projection device and a display method thereof. The display device balances on image generation and image transmission to improve the final display quality.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a projection device, imaging equipment, and an imaging method. Background technique [0002] Optical imaging devices are indispensable entertainment facilities in modern life. From classic TVs, computers, mobile tablets, to smartphones, smart watches, and augmented reality (Augmented Reality, AR) and virtual reality (Virtual Reality, VR) are all specific optical imaging application devices. Some existing imaging devices are implemented by optical transmission or video transmission. More specifically, for augmented reality technology, the optical transmissive method has become a mainstream implementation method because of its high resolution, no visual deviation, no time delay, and more conveniences in line with social habits. [0003] For imaging devices, the light source and light transmission path are equally important. When the image information of the light-emitting element ...
