Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-definition glasses-free 3D display technologies face challenges in reducing data resource waste due to the need for high data transmission bandwidth and causing visual fatigue from focusing on a single point for extended periods.
Innovation Solution
A display device with a substrate, pixel islands, data lines, a multiplexing circuit, and a microlens layer that modulates light to create a three-dimensional display, along with a camera to determine the user's gaze area and adjust the resolution accordingly, allowing for high-resolution display in the gaze area and low-resolution display in non-gaze areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If full-screen high-definition 3D display is implemented, then display resolution is improved, but data transmission bandwidth requirement increases and data resource waste occurs in non-gaze areas
Solution Approach 1:
The patent implements variable resolution display where the gaze area is rendered at high definition (first resolution) while non-gaze areas are rendered at low definition (second resolution). This local quality differentiation ensures that computational and data resources are concentrated on the user's focus area, reducing overall data transmission bandwidth requirements while maintaining high display quality where needed.
Solution Approach 2:
The system dynamically adjusts display resolution based on real-time gaze detection. The controller continuously monitors user eye position through camera feedback and dynamically reconfigures the rendering resolution for different screen regions. This dynamic adaptation allows the display to optimize between high resolution and low data consumption based on current user attention patterns.
2Manufacturing precision
If high-definition display is used, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality enhancement by rendering high-definition images only in the gaze area while using low-definition rendering for non-gaze areas. This significantly reduces the total number of pixels that require high computational processing and power consumption, while maintaining excellent image quality in the user's focus area.
Solution Approach 2:
Instead of rendering the entire screen at high definition, the system applies partial action by focusing computational resources only on the necessary gaze area. This partial rendering approach reduces overall power consumption while delivering sufficient image quality for the user's actual viewing needs.
3Adaptability or versatility
If glasses-free 3D technology is combined with high-definition display, then display experience is improved, but data resource waste occurs due to limited gaze area
Solution Approach 1:
The patent combines glasses-free 3D technology with local quality rendering by generating stereoscopic image pairs only for the gaze area at high resolution, while non-gaze areas use lower resolution. This reduces the data resources required for 3D rendering while maintaining immersive display experience in the user's focus area.
Solution Approach 2:
The system dynamically adapts the 3D rendering resolution based on real-time gaze detection. The controller adjusts the computational effort for generating stereoscopic images in different screen regions, applying high-resolution 3D rendering only where the user is looking and lower-resolution elsewhere, thereby reducing data resource waste.

AI summary
A display apparatus and a driving method therefor. The driving method includes: determining a gaze area and a non-gaze area of a user on a display apparatus in real time (S10); and driving the gaze area for image displaying at a first resolution, and driving the non-gaze area for image displaying at a second resolution, wherein the first resolution is higher than the second resolution. By using of the display apparatus, image resolution can be adjusted according to different areas, so as to realize high-resolution image display in a display area at which a user gazes and realize low-resolution image display in other areas, thereby reducing power consumption and achieving reasonable allocation of resources on the premise of ensuring the user experience.
