Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current glasses-free 3D display technologies suffer from low resolution, insufficient information display, and limited 3D viewing angles due to the limitations of existing subpixel structures and electrode arrangements, which result in issues like moire patterns and display crosstalk.
Innovation Solution
A display panel design featuring a plurality of first-color subpixels with alternately arranged and overlapping first and second electrodes, connected through via holes, and a passivation layer, which allows for independent control of secondary pixels to enhance resolution and viewing angles, and includes a luminescent layer and cathode structure to minimize moire effects and improve light emission continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional subpixel structures and electrode arrangements are used, then manufacturing is simpler, but resolution is low and moire patterns occur
Solution Approach 1:
The patent divides each subpixel into multiple secondary pixels through a segmented electrode arrangement. Specifically, each subpixel contains multiple first electrodes and second electrodes that are alternately arranged and partially overlap, creating distinct secondary pixel regions. This segmentation increases the effective resolution without requiring a complete redesign of the manufacturing process, as it builds upon the existing subpixel structure while adding controlled complexity only where needed for resolution enhancement.
Solution Approach 2:
The patent introduces a vertical dimension to the electrode arrangement by creating overlapping electrode structures at different levels. The first electrodes and second electrodes are positioned at different heights and partially overlap in the vertical dimension, forming a three-dimensional electrode configuration. This dimensional change allows for increased resolution and elimination of moire patterns while maintaining a relatively simple planar manufacturing approach.
2Manufacturing precision
If electrode spacing is reduced to increase resolution, then display detail improves, but display crosstalk increases
Solution Approach 1:
The patent introduces dielectric layers as intermediary structures between the first electrodes and second electrodes. These dielectric layers are positioned between adjacent electrodes of different types and serve as electrical insulators that prevent charge leakage and signal crosstalk. The intermediaries allow electrodes to be placed closer together for higher resolution while maintaining electrical isolation, thus resolving the contradiction between reduced electrode spacing and increased display crosstalk.
3Ease of operation
If glasses-free 3D display technology is implemented, then viewing comfort improves, but 3D viewing angle is limited
Solution Approach 1:
The patent segments each subpixel into multiple secondary pixels with independently controllable electrodes, creating multiple light emission paths within each subpixel. This segmentation enables the display to generate multiple views from a single subpixel, expanding the 3D viewing angle while maintaining the glasses-free format. The segmented structure allows different secondary pixels to direct light to different viewing angles, thereby increasing adaptability without sacrificing viewing comfort.
4Loss of information
If information display capacity is increased, then display content richness improves, but resolution decreases due to pixel crowding
Solution Approach 1:
The patent utilizes the vertical dimension through overlapping electrode structures to increase information display capacity without reducing resolution. By arranging first electrodes and second electrodes at different heights and positions, the patent creates additional display elements within the same planar footprint. This three-dimensional electrode configuration allows more information to be displayed while maintaining high resolution, as the additional display capacity is achieved through vertical stacking rather than horizontal crowding.
