Spliced Display Device Backward Bending Non-Display Region Seam Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-scale LCD/AMOLED displays face challenges in ensuring image continuity and integrity due to non-display regions, which are difficult to manage during splicing, leading to gaps and disruptions in the image.
Innovation Solution
A spliced display device is designed with display panels where one end is backwardly bended to match the non-display region of another panel, allowing for a seamless integration by bending and fixing the non-display regions together, potentially using flexible substrates and organic light-emitting layers, and incorporating conductive elements to connect adjacent panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display panels are spliced together using conventional methods with frames, then the structure is simple and easy to manufacture, but the image continuity and completeness are destroyed due to visible seams and gaps
Solution Approach 1:
The patent transitions from a two-dimensional planar splicing approach to a three-dimensional configuration by bending the non-display regions of display panels backward. This dimensional change allows the non-display regions to overlap and connect with adjacent panels, eliminating visible seams while maintaining manufacturing feasibility through flexible substrate technology.
Solution Approach 2:
The patent employs flexible substrates that enable the display panels to be bent backward at their edges. This flexibility allows the non-display regions to be folded back and connected to adjacent panels, creating a seamless spliced display structure without requiring complex rigid mechanical components.
2Ease of manufacture
If the non-display region is made larger to facilitate splicing, then the ease of manufacture improves, but the display area is reduced
Solution Approach 1:
The patent applies curvature by bending the non-display regions backward at an angle, transforming them from flat extensions into three-dimensional folded structures. This curvature allows the non-display regions to overlap and connect with adjacent panels, achieving easy splicing while minimizing the horizontal space occupied and preserving maximum display area.
3Area of stationary object
If multiple display panels are spliced to create large-scale displays, then the display size increases, but the image completeness is compromised due to frame separation
Solution Approach 1:
The patent merges the non-display regions of adjacent display panels by bending them backward and connecting them together. This merging eliminates the traditional frame separation between panels, creating a unified seamless display surface that maintains image completeness across large-scale spliced configurations.
4Device complexity
If conventional splicing methods are used with frames, then the device complexity is low, but the visual segmentation is prominent
Solution Approach 1:
The patent resolves the contradiction by moving the splicing connection from the two-dimensional display surface to the third dimension through backward bending of non-display regions. This allows the panels to be structurally connected without visible seams on the display surface, achieving visual continuity while maintaining relatively simple splicing structures.
