Tiled Display Boundary Regions for Optical Border Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices using self-emitting light-emitting elements face challenges in enhancing image quality due to visible optical borders between adjacent panels, which are caused by differences in luminance, wavelength, or surface-reflection components of light emitted by adjacent units.
Innovation Solution
A display device configuration that includes a first region emitting first light and a second region emitting second light with different luminance, wavelength, or surface-reflection components, where the second regions are positioned between adjacent first regions, ensuring that the difference in optical characteristics between adjacent units is minimized, thereby reducing the visibility of optical borders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple self-emitting display panels are linked together to form a tiling display, then the display area is expanded, but optical borders become visible between adjacent panels
Solution Approach 1:
The patent applies local quality by introducing a second region with different optical characteristics (different luminance, wavelength, or surface-reflection component) specifically at the boundary areas between display panels. This localized modification allows the boundary regions to emit light with optical characteristics that match adjacent panels, thereby reducing visible optical borders while maintaining the overall expanded display area.
Solution Approach 2:
The patent changes optical parameters (luminance, wavelength, or surface-reflection component) of the light emitted by the second region compared to the first region. By adjusting these parameters, the optical characteristics at panel boundaries are modified to match adjacent panels, reducing the visibility of optical borders while preserving the expanded display area.
2Object-affected harmful factors
If the second region emits light with different optical characteristics from the first region, then the optical border visibility is reduced, but the device complexity increases
Solution Approach 1:
The patent segments each display panel into two distinct regions: a first region for normal display purposes and a second region for boundary matching. This segmentation allows the boundary regions to be independently controlled with different optical characteristics, reducing optical border visibility while maintaining a relatively simple overall structure that can be integrated into existing display technologies.

AI summary
There is provided a display device including a plurality of unit regions disposed adjacent to each other, a first region that is provided in each of the unit regions, and emits first light, and a second region that is provided outside the first region in each of the unit regions, and emits second light. The second light is different from the first light in at least one of luminance, wavelength, or surface-reflection component, the second regions are provided between adjacent ones of the first regions, and a difference in luminance, wavelength, or surface-reflection component between the second light to be emitted from adjacent ones of the unit regions is smaller than a difference in luminance, wavelength, or surface-reflection component between the first light and the second light in a same one of the unit regions.
