Solution Overview
Problem
Conventional display devices, such as liquid crystal panels and OLED panels, face issues like slow response time, high power consumption, short lifespan, and image degradation due to seams between display modules when implementing a large screen, which affects image quality.
Innovation Solution
A display device comprising multiple modules with inorganic light emitting elements mounted on a substrate, featuring a light absorbing pattern to cover gaps between modules and an encapsulation layer to minimize image degradation, including a transparent molding resin or optical adhesive for protection and improved visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display modules are assembled together to create a large screen, then the screen size and resolution are improved, but gaps appear between modules causing image degradation
Solution Approach 1:
The patent extracts the problematic gap between display modules and addresses it separately by filling the gap with a light-absorbing material. This isolates the gap-filling function from the display modules themselves, allowing each module to maintain its original structure while collectively achieving seamless拼接.
Solution Approach 2:
The patent introduces a light-absorbing material as an intermediary substance between adjacent display modules. This intermediary fills the gap and absorbs stray light, preventing image degradation while allowing the modules to remain physically separate for manufacturing and assembly purposes.
2Productivity
If display modules are placed adjacent to each other, then productivity and ease of assembly are improved, but gaps between modules cause harmful light leakage
Solution Approach 1:
The patent converts the harmful effect of light leakage in the gap into a beneficial solution by filling the gap with a light-absorbing material. The same gap that causes light leakage is transformed into a light-trapping region, eliminating the harmful effect while maintaining the modular assembly structure.
Solution Approach 2:
The patent applies a specialized light-absorbing material specifically in the gap regions between modules, where light leakage occurs, while leaving the display modules themselves unchanged. This localized treatment addresses the harmful effect only where needed, maintaining overall assembly efficiency.
3Ease of manufacture
If conventional display technologies like LCD or OLED are used, then manufacturing is simplified, but response time increases and power consumption increases
Solution Approach 1:
The patent changes the fundamental parameter of light emission by using self-emissive micro-LEDs instead of non-emissive LCD or OLED technologies. This parameter change from passive to active light emission achieves faster response times and lower power consumption while maintaining manufacturing feasibility through modular assembly.
