OLED Panel Gap Filling Structure for Tiled Display Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-area displays, such as outdoor display boards, often require multiple display panels to be tiled together, resulting in gaps that negatively impact the visual effect and performance of the electronic device.
Innovation Solution
Incorporating a filling element between adjoined display panels or light emitting plates to improve the performance of the electronic device, with the filling element having different materials and properties to optimize its function.

1Area of stationary object
If multiple display panels are tiled together to form large-area displays, then the display area is increased, but gaps between panels appear that negatively impact visual effect and performance
Solution Approach 1:
A filling element is introduced as an intermediary component between adjacent display panels. This filling element fills the gap between panels, preventing light leakage and improving the visual effect at panel boundaries while maintaining the large display area achieved through tiling.
Solution Approach 2:
The filling element is specifically positioned at the boundary regions between display panels where gaps occur. By applying this local solution only where needed (at panel interfaces rather than across the entire display), the visual effect is improved without affecting the overall display area or requiring complete redesign of the panel structure.
2Area of stationary object
If display panels are adjoined to create large displays, then the display size is increased, but the gap between panels affects the overall visual effect
Solution Approach 1:
The filling element serves as a mediator that bridges the visual and physical gap between adjacent display panels. It is positioned in the gap region and provides optical isolation, preventing light from one panel from leaking into adjacent panels, thereby improving the overall visual effect while preserving the large display size.
Solution Approach 2:
The filling element may incorporate light-absorbing materials or specific optical properties that prevent light leakage and improve contrast at panel boundaries. By controlling the optical characteristics of the filling element, the visual effect is enhanced without compromising the display size.

AI summary
An electronic device includes a first substrate, a second substrate, organic light emitting diodes, a filter layer, a third substrate, a structure, and a first adhesive element. At least a part of the organic light emitting diodes are disposed on the first substrate. The filter layer is disposed at least on the second substrate. The third substrate is disposed corresponding to the first substrate and the second substrate. The organic light emitting diodes and the structure are disposed under the third substrate. The first adhesive element is disposed between the first substrate and the second substrate, directly contacts the structure, and does not overlap with the organic light emitting diodes. A distance between a bottom surface of the structure and a top surface of the third substrate is different from a minimum distance between one of the organic light emitting diodes and the top surface of the third substrate.
