Compressible Transparent Member for Seamless Display Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display wall splicing techniques suffer from visible black lines due to seams between displays, which are not completely resolved by narrow borders or optical elements, as assembly tolerance still results in visible seams.
Innovation Solution
A display device comprising a display panel, a transparent plate, and a compressible transparent member with a tilted light emitting surface, which is compressed to fill the seams between adjacent display devices, refracting the image beam and emitting it perpendicular to the display surface, thereby eliminating visible black lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If displays with slim borders are used to narrow seams between displays, then the visibility of splicing seams is reduced, but assembly tolerance still results in visible black lines
Solution Approach 1:
A transparent optical element is introduced as an intermediary component between adjacent displays. This optical element includes a light incident surface facing the display surface and a light emitting surface that extends along the splicing seam. The optical element receives light from the display surface and emits it along the seam, effectively filling and obscuring the gap between displays, thereby eliminating visible black lines while accommodating assembly tolerances.
2Object-affected harmful factors
If optical elements are installed on display surfaces to shield borders and splicing seams, then seam visibility is reduced, but assembly tolerance still results in visible seams
Solution Approach 1:
The optical element extends in a direction along the splicing seam rather than merely covering the border area. The light emitting surface of the optical element stretches along the seam between adjacent displays, filling the gap in a dimensional manner that accommodates assembly variations and ensures complete coverage of the splicing seam, making it invisible.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively mitigates the issue of visible black lines at splicing seams, ensuring a seamless display with maintained brightness and correct image rendering.
Implementation Method 1
an image beam sent from the display panel to the compressible transparent member can be refracted by the compressible transparent member, and emitted from the splicing seam along a direction perpendicular to the light emitting surface of the display device

AI summary
A display device includes a display panel, a transparent plate and at least one compressible transparent member. The display panel has a display surface. The transparent plate is disposed on the display panel and has a light incident surface and a first light emitting surface opposite to each other. The display surface and the light incident surface face each other, and the transparent plate has at least one side surface connected between the light incident surface and the first light emitting surface. The compressible transparent member is disposed on the side surface and has a second light emitting surface, and the second light emitting surface is tilted relative to the first light emitting surface. Moreover, a display apparatus including a plurality of the display devices is also provided. When the display devices are spliced to form the display apparatus, the problem of visible black lines of splicing seams is mitigated.
