Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D image display devices face issues with crosstalk and chromatic dispersion, especially when increasing the number of viewpoints, leading to reduced resolution and severe Moire phenomena, while also limiting observer mobility and freedom due to narrow viewing zones.
Innovation Solution
A 3D image display device with a lattice-patterned sub-pixel structure and an optical plate or backlight panel featuring inclined light transmission regions or emission units, where the tilt angle is optimized to minimize crosstalk and maintain high resolution, allowing for a wider observation area and continuous motion parallax without chromatic dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an inclined parallax barrier is used to solve chromatic dispersion, then chromatic dispersion is reduced, but crosstalk increases and Moire phenomenon becomes severe
Solution Approach 1:
The patent divides the image display panel into multiple data rows (first data row, second data row, third data row, etc.) with different sub-pixel arrangements. Each data row is segmented to form viewing zones at different positions, allowing the system to express multiple viewpoints while controlling crosstalk through strategic placement of sub-pixels across rows.
Solution Approach 2:
The patent employs asymmetric sub-pixel arrangements where different data rows have different configurations of red, green, and blue sub-pixels. For example, the first data row has a specific arrangement while the second data row has a different arrangement, creating asymmetric viewing zone patterns that reduce crosstalk between adjacent zones.
2Adaptability or versatility
If the number of viewpoints is increased to enhance 3D effect, then 3D image quality is improved, but resolution deteriorates and Moire phenomenon increases
Solution Approach 1:
The patent transitions from a single-plane pixel arrangement to a multi-row dimensional structure where sub-pixels are distributed across multiple data rows. This dimensional expansion allows the system to express multiple viewpoints by utilizing the vertical arrangement of rows, thereby increasing the number of expressible viewpoints without compromising horizontal resolution.
Solution Approach 2:
Different data rows are assigned different local sub-pixel qualities and arrangements. For instance, odd-numbered rows may have one sub-pixel configuration while even-numbered rows have another, allowing each local region to contribute differently to the overall multi-viewpoint image, thus maintaining resolution while increasing viewpoint capacity.
3Device complexity
If a vertical parallax barrier is used to simplify structure, then device complexity is reduced, but viewing zone width is limited and observer mobility is restricted
Solution Approach 1:
The patent creates a dynamic viewing experience by arranging sub-pixels in multiple data rows that form viewing zones at different horizontal positions. This dynamic arrangement allows observers to move horizontally and vertically while still accessing different viewpoints, effectively expanding the usable viewing area without requiring a complex inclined barrier structure.
Solution Approach 2:
The patent expands the viewing zone in the horizontal dimension by utilizing multiple data rows arranged vertically. This dimensional transformation allows the system to provide wide viewing zones and enhanced observer mobility without increasing the complexity of the parallax barrier, as the multi-row sub-pixel arrangement inherently creates expanded viewing areas.
