Display Panel Refractive Device for Borderless Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid-crystal display (LCD) technologies face challenges in achieving true borderlessness due to the space-consuming nature of gate driving circuits, which results in noticeable black borders on both sides of the display panel, negatively impacting the user's viewing experience.
Innovation Solution
A display panel design incorporating a refractive device on the front side of the substrate to refract light from the wiring area, making it invisible to the viewer while allowing light from the display area to be perceived, thereby minimizing or eliminating the black border.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If gate driving circuits are integrated into the display panel, then control functionality is improved, but the black border width increases
Solution Approach 1:
The patent applies GOA (Gate Driver on Array) technology to integrate gate driving circuits directly into the array substrate, transitioning from external flexible circuit boards to in-panel integration. This dimensional reorganization eliminates the need for separate border areas for driver circuits, thereby reducing black border width while maintaining control functionality.
Solution Approach 2:
The gate driving circuits are merged with the array substrate to form an integrated structure. By combining the driver circuit functions with the display array, the patent eliminates separate border regions, achieving both control functionality and reduced black border width simultaneously.
2Ease of manufacture
If the wiring area is made visible to improve manufacturing simplicity, then manufacturing ease is improved, but the viewing experience deteriorates due to noticeable black borders
Solution Approach 1:
The patent applies a black matrix material to the wiring area, changing its optical appearance to match the surrounding black border regions. This color matching makes the wiring area visually imperceptible, eliminating the harmful effect of noticeable black borders while maintaining manufacturing simplicity through standard materials and processes.
3Object-affected harmful factors
If the black border is completely eliminated to achieve true borderlessness, then viewing experience is improved, but the wiring area becomes completely invisible which may cause detection issues
Solution Approach 1:
The patent applies different optical properties to different regions: the display area maintains its normal light transmission characteristics for visibility, while the wiring area is treated with black matrix material for visual concealment. This local differentiation allows the wiring area to be visually imperceptible as part of the black border while remaining detectable through manufacturing inspection processes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The refractive device effectively reduces or eliminates the black border, enhancing the viewing experience by making the wiring area unperceivable, thus achieving a narrower border or borderlessness.
Implementation Method 1
a refractive device is disposed on a front side of the substrate to refract light from the display area and the wiring area
Data Source
AI summary
A display panel and a display device are provided. The display panel includes a substrate. The substrate includes a display area in the middle of the substrate and a wiring area around the display area. A refractive device is disposed on the front side of the substrate to refract light from the display area and the wiring area and so partially or totally prevent the wiring area from being seen.
