Display Panel Binding Layout for Narrow Seam Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-screen display technologies face challenges in achieving seamless image continuity due to the formation of wide splicing seams when splicing multiple displays with small display areas together.
Innovation Solution
The display panel design includes a front surface with a display region for picture display and a back surface with a binding region that overlaps with the display region. A first flexible substrate is positioned between the thin-film transistor layer and the binding region, allowing the binding region to be placed on the opposite side of the display panel from the display region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple displays with small display areas are spliced together to form a large-screen display, then the display area is increased, but wide splicing seams are formed between adjacent displays affecting image continuity
Solution Approach 1:
The binding region is moved from the same side as the display region to the opposite side of the display panel. This spatial reconfiguration allows the binding region to overlap with the display region in the overlapping view direction, effectively hiding the binding region behind the display region and eliminating visible splicing seams between adjacent displays.
2Ease of manufacture
If the binding region is disposed on the same side as the display region, then the signal lines can be easily connected to IC components, but wide splicing seams are formed between adjacent displays
Solution Approach 1:
The binding region is repositioned to the opposite side of the display panel, allowing it to overlap with the display region in the overlapping view direction. This maintains ease of manufacturing by keeping the binding region accessible for signal line connections while eliminating visible splicing seams.
Solution Approach 2:
The binding region is positioned to overlap with the display region, allowing the binding region to be effectively 'nested' within the spatial footprint of the display region when viewed from the front. This nesting arrangement hides the binding region behind the display region, eliminating visible seams while maintaining manufacturing accessibility.
3Adaptability or versatility
If flexible displays are bent at an angle to splice them together, then the binding region can be positioned differently, but splicing seams with certain width are still formed
Solution Approach 1:
Instead of bending the flexible display to reposition the binding region, the patent directly positions the binding region on the opposite side of the display panel in a planar configuration. This eliminates the need for bending while achieving the same goal of overlapping the binding region with the display region to hide splicing seams.

AI summary
A display panel includes a front surface, a back surface, a display region, a binding region, a first flexible substrate, and a thin-film transistor. The display region is arranged on the front surface and configured to display a picture. The binding region is arranged on the back surface and at least partially overlaps with the display region. The thin-film transistor layer is arranged on a side of the first flexible substrate close to the front surface of the display panel. The first flexible substrate is arranged between the thin-film transistor layer and the binding region.
