Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies, such as liquid crystal panels and OLED panels, face issues like slow response time, high power consumption, difficulty in compact design, and screen burn-in, while micro-LED panels offer better contrast, response times, and energy efficiency but require improved structural support and assembly methods.
Innovation Solution
A display apparatus comprising a frame with a frame panel and insert portion, studs, and brackets that support multiple display modules in an M*N matrix, allowing for detachable coupling and efficient heat dissipation, along with a manufacturing method that includes forming insert portions and attaching reinforcing members for enhanced structural integrity and heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If micro-LED panels are used to replace OLED panels, then luminance, resolution, power consumption, and durability are improved, but structural support and assembly methods require improvement
Solution Approach 1:
The display apparatus is divided into multiple display modules arranged in an M*N matrix, with each module independently mounted on the frame. This segmentation allows for simplified assembly and replacement of individual modules while maintaining overall system reliability
Solution Approach 2:
The frame is pre-designed with insert portions and coupling structures before the display modules are installed. This preliminary preparation of the mounting structure simplifies the assembly process and ensures proper structural support for the micro-LED panels
2Adaptability or versatility
If display modules are arranged in an M*N matrix on the frame, then various resolutions and screen sizes can be manufactured according to customer order, but the frame structure requires enhanced support
Solution Approach 1:
The frame panel includes openings of different sizes at different locations to accommodate various display module configurations. The asymmetric arrangement of openings and support structures allows the same frame design to adapt to different screen sizes and resolutions while maintaining structural integrity
Solution Approach 2:
The frame incorporates local reinforcement at specific positions where display modules are mounted, with varying thickness and material properties in different regions. This localized strengthening provides enhanced support where needed while keeping the overall frame lightweight and adaptable
3Use of energy by moving object
If inorganic light emitting devices are mounted on substrates, then self-light emission and energy efficiency are achieved, but heat dissipation requires improved management
Solution Approach 1:
The heat dissipation function is extracted from the display module itself and transferred to a dedicated heat dissipation structure integrated into the frame. This separation allows the micro-LED panels to operate efficiently while the frame's thermal management system handles the heat dissipation
Solution Approach 2:
A heat dissipation intermediary structure is introduced between the display modules and the frame, facilitating thermal transfer from the high-energy micro-LED devices to the frame's heat dissipation pathways. This intermediary layer improves thermal management while maintaining the energy efficiency benefits of inorganic LEDs
