3D Display Panel Asymmetric Pixel Design for Moire Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies suffer from the Moire effect due to uneven fringes caused by the geometric arrangement of black matrix regions and metal wiring, particularly exacerbated by low-temperature polysilicon active device arrays, which affects display quality.
Innovation Solution
A three-dimensional display design incorporating a lenticular lens array or parallax barrier with a display panel featuring non-rectangular pixel regions and mirror-image transparent regions, where semiconductor patterns overlap to maintain consistent transmittance loss, reducing the Moire effect and improving display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a barrier is configured between the display panel and the user to control images captured by respective eyes, then 3D image display is achieved, but Moire effect occurs due to geometric arrangement of black matrix regions and metal wiring
Solution Approach 1:
The patent applies asymmetry by configuring transparent regions in adjacent pixels with different geometric arrangements. Specifically, first pixels have transparent regions arranged in one pattern while second pixels have transparent regions arranged in a different pattern, breaking the symmetry that causes Moire effect with the barrier slits. This asymmetric design prevents the formation of equidistant bright-and-dim fringes while maintaining 3D display functionality.
2Ease of manufacture
If low-temperature polysilicon active device array is used in the display panel, then manufacturing is simplified, but light strength distribution becomes uneven and Moire effect worsens
Solution Approach 1:
The patent applies local quality by making different regions of the pixel array have different transparent region configurations. First pixels in odd rows have one transparent region arrangement while second pixels in even rows have another arrangement. This local variation compensates for the uneven light strength distribution caused by polysilicon wirings, as each local region's transparent regions are optimized to counteract the specific wiring pattern in that area, thereby reducing Moire effect while maintaining ease of manufacture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively minimizes the Moire effect and enhances display quality by ensuring uniform transmittance and reduced bright-and-dim fringes, resulting in a clearer 3D image without the distortion caused by the Moire effect.
Implementation Method 1
The lenticular lens array comprises a plurality of lenticular lenses extending along directions parallel to each other
Implementation Method 2
The parallax barrier includes a plurality of slits extending along directions parallel to each other. The images respectively captured by a viewer's left and right eyes respectively pass through the slits of the barrier

AI summary
A three-dimensional display includes a display panel having a plurality of first pixels arranged in the odd row, and a plurality of second pixels arranged in the even row. Each first pixel has a first and a second transparent regions and a first semiconductor pattern. Each second pixel has a third and a fourth transparent regions and a second semiconductor pattern. In any two adjacent first and second pixels, the first and the third transparent regions are mirror images of each other, and the second and the fourth transparent regions are mirror images of each other. In the adjacent first and second pixels arranged in any two rows, the loss of the light transmittance at any position along the row direction due to overlapping of the first semiconductor and the first transparent region and overlapping of the second semiconductor and the fourth transparent region remains unchanged.
