Display Extension Board Layout Reducing Connectors for Local Dimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges with numerous connectors and cables connecting LED drivers and substrates, leading to increased costs, complex layouts, and prolonged working times, especially when dealing with large numbers of local dimming blocks.
Innovation Solution
A display device structure featuring a display panel, frame, substrates, and an extension board with driver chips, where the substrates are coupled to the extension board in a direction intersecting them, reducing the need for multiple connectors and cables by integrating the LED driver board with a main board or power supply board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connectors and cables are used to connect LED drivers and substrates, then the number of local dimming blocks can be increased, but the device complexity and manufacturing cost increase
Solution Approach 1:
The extension board integrates multiple driver chips and connector functions into a single unified structure. Multiple substrates are connected to the extension board through a unified coupling mechanism, eliminating the need for separate connectors and cables for each substrate-d driver connection. This merging approach maintains support for multiple local dimming blocks while reducing overall system complexity.
Solution Approach 2:
The extension board serves multiple functions simultaneously: it provides electrical connections to multiple substrates, houses multiple driver chips for different local dimming blocks, and offers a unified coupling interface. This multi-functional design allows a single component to replace what would traditionally require multiple separate connectors and cables.
2Adaptability or versatility
If multiple connectors and cables are used to connect LED drivers and substrates, then the number of local dimming blocks can be increased, but the working time and cost increase
Solution Approach 1:
By combining multiple connection functions into the single extension board structure, the assembly process is simplified. Workers need to perform fewer separate connection operations, as multiple substrates are coupled to the extension board through a unified mechanism rather than requiring individual connector installations for each substrate-driver pair.
3Adaptability or versatility
If multiple connectors and cables are used to connect LED drivers and substrates, then the number of local dimming blocks can be increased, but the layout complexity increases
Solution Approach 1:
The extension board consolidates multiple driver chips and connection interfaces into a single organized structure with a unified coupling area. This arrangement creates a more compact and orderly layout compared to having separate connectors and cables distributed throughout the display device, making the overall structure easier to manage and assemble.
