Distributed Driver Blocks for Narrow Bezel Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display apparatuses with non-rectangular display regions, the concentration of driver ICs leads to a widened bezel width, which is undesirable for maximizing the display area.
Innovation Solution
The arrangement of scan driver blocks in one side portion and data driver blocks in an opposing side portion of the display apparatus, with intersecting scan lines and data lines configured to reduce the necessary region for driver block placement, allowing for a narrower bezel width and even distribution around the display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If driver ICs are disposed in a concentrated manner in a partial region of the outer circumference, then the driver circuit can be efficiently arranged, but the bezel width in that region widens
Solution Approach 1:
The driver circuit is divided into multiple independent driver blocks (first driver block, second driver block, third driver block, fourth driver block) that are distributed around the outer circumference of the display region. Each driver block independently drives a corresponding pixel group, eliminating the need for concentrated driver IC placement and reducing bezel width in any single region.
Solution Approach 2:
Different driver blocks are positioned at different locations around the display region's outer circumference, with each driver block optimized to drive its specific pixel group. This distributed arrangement allows the bezel width to be uniformly minimized across all regions while maintaining efficient driver circuit functionality.
2Device complexity
If driver ICs are disposed in a concentrated manner, then the driver circuit layout is simplified, but the display area is reduced due to widened bezel
Solution Approach 1:
The driver circuit is segmented into multiple driver blocks distributed around the display region, eliminating the need for large concentrated driver IC areas. This allows the display area to be maximized while maintaining simplified driver circuit functionality through modular, distributed architecture.
Solution Approach 2:
Instead of concentrating driver ICs in a single linear region, the driver blocks are distributed along the circumferential dimension of the display region. This dimensional redistribution allows efficient driver circuit layout without sacrificing display area, as the driver components are spread around the perimeter rather than concentrated in one location.
