Solution Overview
Problem
Current projection display apparatuses lack the capability to display 8K resolution images, as they do not have corresponding 8K projection display components, necessitating a breakthrough in signal processing and display technology.
Innovation Solution
A projection display apparatus comprising a motion deblurring circuit, image processing circuit, color managing circuit, and a multi-axis shifting device, which processes input video signals to reduce motion blur, convert them to higher resolutions, separate color components, and shift images to achieve higher resolution display through a digital micro display component and projection device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a general projection display apparatus is used, then the device complexity is low, but the display resolution cannot reach 8K
Solution Approach 1:
The patent divides the 8K resolution display into multiple 4K sub-images that are processed and projected separately. The image processing circuit converts a single 8K image into multiple 4K sub-images, which are then displayed by the projection device in sequence. This segmentation allows achieving 8K resolution without requiring an expensive 8K projection component.
Solution Approach 2:
The patent introduces a temporal dimension by displaying multiple 4K sub-images in rapid succession. The multi-axis shifting device shifts the projected image in different directions for each sub-image, creating a time-based sequence that the human eye perceives as a single high-resolution image. This transforms a spatial resolution problem into a temporal display problem.
2Manufacturing precision
If motion deblurring processing is applied, then the image quality is improved, but the processing time is increased
Solution Approach 1:
The motion deblurring circuit performs motion compensation and deblurring processing on the input video signal before it is converted into multiple 4K sub-images. By preprocessing the video signal with motion information, the system reduces motion blur in the final displayed image without adding significant delay during the actual display process.
3Manufacturing precision
If 8K input signals are converted to multiple 4K output signals, then the display resolution is improved, but the device complexity is increased
Solution Approach 1:
The projection device is designed to perform multiple functions: it can display both standard 4K images and the sequence of 4K sub-images that compose an 8K image. The multi-axis shifting device also serves dual purposes by both positioning the image on the screen and creating the temporal sequence for resolution enhancement. This multi-functionality reduces the need for additional dedicated components.

AI summary
A projection display apparatus includes a motion deblurring circuit, an image processing circuit, a color managing circuit, an image projection display device and a multi-axis shifting device. The motion deblurring circuit receives an input video signal with the first resolution and processes it to reduce a motion blur. The image processing circuit receives the input video signal processed by the motion deblurring circuit, and converts it into a plurality of the output video signals with the second resolution. The color managing circuit receives the output video signals with the second resolution, separates the color of the output video signals, and outputs it. The projection device including a digital micro display component has a native resolution with a second resolution, and displays the output video signals. The multi-axis shifting device shifts the output video signals outputted from the image projection display device onto a projection screen with a control timing signal.
