Dual-Display Device with Segmented Gate Lines for Impact Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices capable of only single image on a monitor are unsuitable for military or industrial applications exposed to impact, as they may malfunction or be damaged, leading to operational issues.
Innovation Solution
A display device with separate first and second display areas, each with independently driven gate and data lines, allowing for dual image display on a single screen, and a layout that maximizes the distance between gate lines to prevent static electricity, enabling continued operation even if one area is damaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a display device uses a single display area with shared gate lines, then the device complexity is reduced, but the reliability decreases when exposed to impact damage
Solution Approach 1:
The display panel is divided into two independent display areas (first display area and second display area), each with its own set of gate lines and data lines. This segmentation allows one display area to continue functioning even if the other is damaged by impact, thereby improving reliability without requiring a completely redundant dual-monitor system.
2Area of stationary object
If gate lines are positioned closer together, then the display area increases, but static electricity occurs between adjacent electrodes
Solution Approach 1:
The harmful effect of static electricity between adjacent gate lines is eliminated by extracting or removing the problematic close-proximity arrangement. Instead, gate lines are positioned at greater distances from each other, specifically with the second gate lines located above the first gate lines in a diagonal direction, thereby preventing static electricity while maintaining display functionality.
3Adaptability or versatility
If a single image is displayed on one monitor, then the ease of operation is simplified, but the adaptability for military and industrial applications is reduced
Solution Approach 1:
The display device achieves multi-functionality by enabling both display areas to operate independently or simultaneously. The first and second display areas can display different images for military/industrial applications (enhancing adaptability) or the same image for simplified operations (maintaining ease of use). This universal design allows the system to adapt to various operational requirements.
