Transparent Display Panel Spacer Distribution for Mask Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In partially transparent display panels, the spacers in the transparent area provide weak support during manufacturing, leading to potential damage to the film layer and result in non-uniform visual color errors when viewed from different angles due to asymmetrical spacer distribution.
Innovation Solution
The display panel incorporates a higher density of first pixel apertures in the transparent area with symmetrical spacers on opposite sides, ensuring adequate support for the mask and uniform spacer distribution to prevent color errors, while maintaining transparency and supporting requirements for both transparent and non-transparent areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If spacers are sparsely distributed in the transparent display area, then transparency is maintained, but mask support becomes insufficient leading to film layer damage
Solution Approach 1:
The patent applies different spacer distribution densities to different display areas: the transparent display area uses a first spacer distribution density while the non-transparent display area uses a second spacer distribution density. This local differentiation allows the transparent area to maintain adequate transparency while still providing sufficient mask support, resolving the contradiction between transparency and structural reliability during manufacturing.
2Ease of manufacture
If spacers are asymmetrical in distribution, then manufacturing is simpler, but visual color errors occur when viewed from different angles
Solution Approach 1:
The patent employs symmetrical spacer distribution patterns around pixel apertures, where spacers are positioned at regular intervals and distances from each aperture. This symmetrical arrangement ensures uniform optical properties when viewed from different angles, eliminating visual color errors while maintaining manufacturing feasibility through standardized positioning.
3Manufacturing precision
If aperture density is increased in transparent area, then display resolution improves, but transparency decreases
Solution Approach 1:
The patent implements different aperture densities in different display areas: the transparent display area uses a first aperture density while the non-transparent display area uses a second aperture density. This allows the transparent area to achieve adequate display resolution while preserving transparency by not over-populating it with apertures, thus resolving the contradiction between resolution and transparency.

AI summary
The present disclosure relates to a display panel and a display device. The display panel includes a transparent display area, and a non-transparent display area. The transparent display area has a plurality of first pixel apertures, and the non-transparent display area has a plurality second pixel apertures. A density of the first pixel apertures of the transparent display area is smaller than a density of the second pixel apertures of the non-transparent display area, and opposite sides of each the first pixel aperture are provided with first spacers.
