Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular display apparatuses face limitations in installation and maintenance due to the need for dismantling cables when replacing timing controller boards or display modules, leading to potential image errors and difficulty in cleaning.
Innovation Solution
Implementing a display apparatus with a first board and a second board connected via wireless communication, where the first board generates driving signals and transmits them wirelessly to the second board, which distributes them to display modules without physical connections, allowing easy module replacement and reducing cable-related issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are used to connect timing controller board and display modules, then stable electrical connection is achieved, but installation and maintenance become complex requiring cable dismantling
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The timing controller board and display modules communicate through wireless signals (e.g., radio frequency communication) instead of physical cable connections. This eliminates the need for cable assembly and disassembly during installation and maintenance while maintaining reliable data and control signal transmission between components.
Solution Approach 2:
The patent extracts and removes the cable connection component from the system architecture. By eliminating cables entirely, the system achieves wireless communication between the timing controller board and display modules, simplifying the overall structure and making the display module independently replaceable without dealing with cable connections.
2Reliability
If multiple cables connect timing controller board to display modules, then complete signal transmission is achieved, but potential image errors occur from defective cables
Solution Approach 1:
The patent substitutes wireless communication for cable-based signal transmission. By using wireless protocols (such as RF or other wireless communication standards), the system transmits control signals and image data without physical cables, thereby eliminating image errors caused by cable defects, poor connections, or cable damage while maintaining complete signal transmission.
3Reliability
If display modules are connected with cables to timing controller board, then electrical connection is established, but cleaning becomes difficult due to cable interference
Solution Approach 1:
The patent removes cables from the system architecture, enabling wireless communication between the timing controller board and display modules. This extraction of the cable component provides unobstructed access to the rear surfaces and edges of display modules, allowing easy cleaning and maintenance without any cable interference in the physical space around the modules.
4Reliability
If physical cable connections are used between boards, then stable power and signal transmission is achieved, but module replacement requires cable disconnection
Solution Approach 1:
The patent replaces the mechanical cable connection system with wireless communication, allowing display modules to be replaced by simply detaching the module itself without any cable disconnection or reconnection operations. The wireless communication system automatically re-establishes connections after module replacement, making the replacement process as simple as removing and installing the module while maintaining stable power and signal transmission.
