Display Panel Stage Layout for Narrower Non-Display Borders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels have a significant non-display region that reduces the effective display area, which is a concern for multimedia electronic devices aiming to minimize bezel size.
Innovation Solution
The display panel design includes a novel arrangement of stages and output wires, with alternating first and second stages and output wires positioned in a specific pattern to reduce the non-display region by optimizing the layout of scan and data driving circuits.

Engineering Contradiction Analysis
1Area of stationary object
If conventional display panel layout is used, then driving circuits can be properly arranged, but the non-display region width becomes large
Solution Approach 1:
The display panel is divided into multiple stages (first stage, second stage, etc.) with alternating first and second output wires extending from different regions. This segmentation allows driving circuits to be distributed across multiple regions rather than concentrated in one area, reducing the non-display region width while maintaining proper circuit arrangement
Solution Approach 2:
The patent utilizes both first direction (upper-lower ends) and second direction (left-right sides) for wire extensions and circuit arrangements. By transitioning from a single-dimension layout to a two-dimensional arrangement of stages and wires, the design optimizes space utilization and reduces the non-display region width
2Area of stationary object
If non-display region width is reduced, then display area is enhanced, but circuit wiring becomes more complex
Solution Approach 1:
Multiple output wires (first output wires, second output wires) extend from different regions (first lower end region, second upper end region) of different stages. This segmentation distributes the wiring load across multiple paths rather than requiring single long wires, reducing overall wire extension length while enhancing display area
Solution Approach 2:
The alternating stage structure acts as an intermediary, allowing output wires to extend from intermediate regions (lower end of first stage, upper end of second stage) rather than from a single remote location. This reduces the effective wire extension length needed to reach all display regions
