Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices have a significant bezel region where images are not displayed, limiting the visible display area and affecting the aesthetic appeal and functionality.
Innovation Solution
The design of the display device includes a unique arrangement of drivers in the corner and edge regions of the display panel, allowing for a reduced bezel size by optimizing the placement and shape of pixel driving circuits and light emission elements, thereby increasing the inner space for pixel disposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display region is expanded to reduce the bezel, then the visible display area increases, but the space for disposing driving circuits and other components becomes insufficient
Solution Approach 1:
The display panel is divided into a display region and a non-display region, with the non-display region further segmented into edge regions and corner regions. This segmentation allows different types of driving circuits to be disposed in different regions, optimizing space utilization while maintaining a large display area.
Solution Approach 2:
Different driving circuits are disposed in different regions of the non-display area based on local space characteristics. Edge regions accommodate certain driving circuits while corner regions accommodate others, allowing each region to be utilized according to its geometric properties and reducing overall bezel size.
2Area of stationary object
If the bezel size is reduced, then the aesthetic appeal and visible display area improve, but the placement and shape of drivers become more constrained
Solution Approach 1:
The driving circuits in corner regions are designed with asymmetric shapes that adapt to the corner geometry, while edge region circuits have different configurations. This asymmetric design allows efficient space utilization in constrained areas while maintaining manufacturing feasibility.
Solution Approach 2:
The patent utilizes the two-dimensional space of the non-display region by disposing different driving circuits in different spatial locations (edge vs. corner regions). This dimensional utilization maximizes the use of available space without increasing the physical size of the display panel.
3Manufacturing precision
If the inner space for pixel disposition is secured, then the display quality improves, but the bezel region occupies more area
Solution Approach 1:
Driving circuits are extracted from the display region and disposed in the non-display region, specifically in edge and corner regions. This extraction allows the display region to be maximized while maintaining all necessary driving functions, thereby reducing the effective bezel area while preserving pixel disposition space.
