Display Pixel Layout for Seamless Mixed-Resolution Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with different resolution areas often exhibit visible boundaries due to differences in pixel density, leading to suboptimal display quality and potential color mixing.
Innovation Solution
The arrangement of light emitting areas with specific sizes and positions on a display panel, where centers of adjacent areas are aligned on axes, maintains a constant interval between high and low resolution areas, preventing visible boundaries and color mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the first display area has a high resolution and the second display area has a lower resolution, then the light transmittance through the second display area is higher, but the boundary between the first and second display areas becomes visible
Solution Approach 1:
The patent applies local quality by making the light emitting areas at the interface have different sizes and arrangements depending on their location. Specifically, the light emitting area in the second display area adjacent to the first display area is configured with a different size than other light emitting areas in the second display area, creating a gradual transition in pixel density at the boundary region while maintaining high light transmittance in the second display area.
Solution Approach 2:
The patent changes the parameter of light emitting area size at the interface between the first and second display areas. The light emitting area in the second display area adjacent to the first display area is configured to have a different size compared to light emitting areas farther from the interface, creating a gradual transition that reduces boundary visibility while maintaining high light transmittance.
2Manufacturing precision
If light emitting areas are arranged to produce a gradual decrease in light intensity from the first display area to the second display area, then boundary visibility is reduced, but the arrangement complexity increases
Solution Approach 1:
The patent implements local quality by applying a special arrangement configuration only to the light emitting areas at the interface between the first and second display areas, while other light emitting areas in the second display area use a standard configuration. This localized approach reduces boundary visibility without requiring complex arrangements throughout the entire display area.
Solution Approach 2:
The patent employs asymmetry by making the light emitting area in the second display area adjacent to the first display area have a different size and configuration than other light emitting areas in the second display area. This asymmetric arrangement creates a gradual light intensity transition at the boundary while maintaining simplicity in other regions.
3Illumination intensity
If the second display area has a lower pixel density, then the light transmittance is higher, but the resolution is lower
Solution Approach 1:
The patent applies local quality by configuring the light emitting area in the second display area adjacent to the first display area with a different size than other light emitting areas in the second display area. This creates a local region with intermediate pixel density at the boundary, allowing high light transmittance in the second display area while reducing boundary visibility through a gradual transition.

AI summary
A display apparatus is disclosed that includes a first display area and a second display area adjacent to the first display area. The first and second display areas include first and second light emitting areas having first and second pixel densities, respectively. The first and second light emitting areas at an interface between the first and second display areas are arranged such that in operation light emitted by the first and second light emitting areas produces a gradual decrease in light intensity from the first display area to the second display area near the interface.
