Chip Array Segmentation for LED Display Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods for LED display screens face the issue of increased electromagnetic radiation when attempting to enlarge the data transmission range, which also leads to higher costs.
Innovation Solution
A control system and method that utilize a chip array with multiple rows of chip assemblies, where each row includes at least two cascaded chip sets, and a controller generates sub-display signals to distribute data across these sets, allowing for a larger display range with reduced electromagnetic radiation by using a series-parallel mixed connection mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If signal transmission speed is increased to enlarge data transmission range, then data transmission range is improved, but electromagnetic radiation increases
Solution Approach 1:
The patent divides the chip array into multiple independent groups, with each group capable of receiving data independently. This segmentation allows the system to expand the display range by adding more groups without increasing the transmission speed within each group, thereby avoiding increased electromagnetic radiation while achieving larger coverage area.
2Length of stationary object
If signal transmission speed is increased to enlarge data transmission range, then data transmission range is improved, but cost increases
Solution Approach 1:
By segmenting the chip array into multiple independently controllable groups, the system can achieve larger display ranges using standard transmission speeds, avoiding the need for expensive high-speed transmission equipment and reducing overall system cost.
3Device complexity
If series connection mode is used to connect chips, then device complexity is reduced, but data transmission range is limited
Solution Approach 1:
The patent implements a hybrid connection mode where chips within each group are connected in series (maintaining simplicity), but multiple groups are connected in parallel (enabling extended range). This segmentation approach balances structural simplicity with expanded data transmission capability.
Solution Approach 2:
The patent transitions from a one-dimensional series connection to a two-dimensional array structure with multiple independent groups. This dimensional change allows the system to achieve larger transmission ranges by adding groups in parallel without increasing the complexity of individual connection paths.
