1Ease of operation
If video card-level backup is implemented, then the backup scope is simplified and easier to manage, but when a certain chip within a video card fails, the backup of the entire video card is affected
Solution Approach 1:
The patent segments the video card backup system into independent chip-level units. Each LED driver chip is equipped with independent data input pins and data output pins that can be connected in series to form multiple independent data links. This segmentation allows individual chips to be backed up independently rather than requiring entire video card backup, thus improving reliability while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent introduces a new dimension of data transmission by creating multiple parallel data links between chips. Instead of a single data path, the system establishes series connections where data can flow through multiple independent paths. This dimensional expansion from single-path to multi-path transmission provides redundancy at the chip level, allowing backup continuity even when individual chips fail.
2Reliability
If multiple independent data links are established between LED driver chips, then chip-level data backup reliability is improved, but the device complexity increases
Solution Approach 1:
The patent divides the complex data link configuration into standardized, repeatable chip modules. Each LED driver chip contains predefined data input pins and data output pins with fixed connection patterns. This segmentation transforms the overall complex system into simple, identical units that can be assembled in series, reducing the complexity of individual components while achieving system-level reliability through replication.
Solution Approach 2:
The patent employs homogeneous LED driver chips with identical pin configurations and data transmission capabilities. Each chip in the series connection follows the same design template with matching data input and output interfaces. This homogeneity simplifies the overall system complexity by eliminating the need for customized configurations, allowing identical modules to be chained together to form reliable multi-path data links.
