Spherical Display Panel Pixel Pitch Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for configuring display panels on spherical display devices result in defects, gaps, or crowding when the pixel pitch is less than 2 mm, leading to suboptimal visual experience due to increased sensitivity of human eyes to pixel arrangement.
Innovation Solution
The display panel configuration involves arranging display configuration groups on a substrate with varying display pitches and numbers, ensuring that each group has a unique quantity of display rows, and optimizing the pixel arrangement to avoid defects and enhance visual clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional pixel take-out method is used to reduce pixel pitch below 2 mm, then the display resolution is improved, but the human eyes become more sensitive to pixel arrangement causing defects, gaps or crowding
Solution Approach 1:
The patent applies local quality by implementing different pixel configurations in different regions of the display panel. Specifically, the display panel is divided into multiple zones with different pixel pitches and/or pixel arrangements, allowing each region to be optimized for its specific function. This resolves the contradiction by maintaining fine pixel pitch (high manufacturing precision) in critical areas while using coarser or different arrangements in other areas, thereby avoiding visible defects while preserving overall visual quality.
Solution Approach 2:
The patent segments the display panel into multiple independent configuration groups, each with its own pixel pitch and arrangement characteristics. This segmentation allows different parts of the display to have optimized pixel densities for their specific purposes, preventing the uniform fine-pitch arrangement from causing visible defects across the entire display while maintaining high resolution where needed.
2Adaptability or versatility
If multiple display panels are spliced to form spherical display device, then the envelopment and presence are enhanced, but the splicing location has edge frame causing ill visual effect
Solution Approach 1:
The patent applies asymmetry by designing the pixel arrangement and configuration groups to be non-uniform across the display panel. The pixel pitch, orientation, and density are varied asymmetrically to match the curvature and viewing angles of the spherical display device. This asymmetric configuration helps mask the splicing locations and edge frames by creating natural visual transitions, thereby maintaining the envelopment effect while reducing the visibility of seams.
Solution Approach 2:
The patent implements spheroidality by configuring the pixel arrangement to follow the curved surface of the spherical display device. The display configuration groups are arranged to accommodate the spherical geometry, with pixel pitch and orientation varying across the surface to match the curvature. This curved pixel layout helps eliminate the appearance of straight edge frames at splicing locations, making the transitions between panels less noticeable and preserving the immersive envelopment effect.

AI summary
A display panel adapted to a spherical display device includes a substrate and a plurality of display configuration groups. The display configuration groups are arranged on the substrate along a first direction. Each of the display configuration groups corresponds to a display number and a display pitch. Each of the display configuration groups includes at least one display row arranged along the first direction. Each of the at least one display row of each of the display configuration groups is arranged along a second direction orthogonal to the first direction according to the corresponding display number and the corresponding display pitch. At least two of the display configuration groups include different quantities of the at least one display row from each other.
