Multi-Display Panel Edge Structure for Bezel-Free Image Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display apparatuses suffer from image discontinuity due to bezel areas between adjacent display units, which degrade the user experience by creating a sense of separation in the connected screen.
Innovation Solution
A display apparatus and multi-display apparatus design that eliminates bezels by using a dam pattern and laser patterning to isolate light emitting devices, ensuring water resistance and enhancing reliability, while maintaining an air-bezel structure to prevent image discontinuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bezel area is provided to cover the edge portion of the display panel, then the light emitting devices are protected and isolated, but the width of the bezel increases and creates image discontinuity in multi-display apparatuses
Solution Approach 1:
The patent extracts the protective function from the traditional bezel structure and relocates it to the edge portion of the display panel itself. The edge portion is configured to expose the laser patterning portion that isolates adjacent light emitting devices, eliminating the need for a separate bezel while maintaining protection functionality.
Solution Approach 2:
The solution transitions from a two-dimensional bezel area covering the edge to a three-dimensional edge portion structure that vertically exposes the laser patterning portion. This dimensional change allows the protective function to be integrated into the panel's edge structure rather than requiring a separate planar bezel.
2Reliability
If a bezel is provided to isolate light emitting devices, then device degradation is prevented, but image discontinuity occurs between adjacent displays in multi-display apparatuses
Solution Approach 1:
The patent merges the protective isolation function with the display panel's edge structure. The edge portion and laser patterning portion are integrated into a single unified structure that both protects the light emitting devices and maintains visual continuity, eliminating the harmful effect of image discontinuity while preserving protection functionality.
Solution Approach 2:
The laser patterning portion acts as an intermediary structure that provides isolation between adjacent light emitting devices without creating a visible bezel. This intermediary structure enables device protection while maintaining image continuity across multiple displays.
3Object-generated harmful factors
If the display panel edge is exposed without a bezel, then image continuity is achieved, but light emitting devices may degrade due to lack of protection
Solution Approach 1:
The patent applies preliminary protective action by configuring the edge portion to expose the laser patterning portion before any potential degradation can occur. This pre-configured protective structure ensures that light emitting devices are isolated from adjacent devices while maintaining image continuity, preventing degradation proactively rather than reactively.
