Detachable SerDes Conversion Module for Low-Noise Display Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face complexities in connecting multiple external apparatuses due to complex connection lines and potential communication interference caused by the integration of high-speed Serializer/Deserializer (SerDes) communication circuits with the basic display apparatus circuit on the same substrate, leading to communication noise and interference.
Innovation Solution
A modular conversion apparatus for high-speed communication is introduced, detachable from the display apparatus, which includes a SerDes for converting serial to parallel signals and a separate power supply to prevent noise interference, allowing for independent operation and upgrading of the display system's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If SerDes communication circuit and basic display apparatus circuit are integrated on the same substrate, then device complexity is reduced, but communication interference and power noise increase
Solution Approach 1:
The patent divides the display system into two separate modules: a display apparatus and a detachable conversion apparatus. The SerDes communication circuit is isolated in the conversion apparatus, while the basic display circuit remains in the display apparatus. This segmentation prevents mutual interference between high-speed communication signals and basic circuit operations, resolving the contradiction between integration simplicity and interference prevention.
Solution Approach 2:
The SerDes communication circuit is extracted from the main display apparatus substrate and placed in a separate conversion apparatus. This extraction removes the source of power noise and communication interference from the display apparatus, allowing the basic display circuit to operate without disturbance while maintaining the capability for high-speed communication when needed.
2Adaptability or versatility
If multiple external apparatuses are connected to the display apparatus, then functionality is enhanced, but connection complexity increases
Solution Approach 1:
The conversion apparatus serves multiple functions: it provides SerDes high-speed communication capability, acts as a signal converter between serial and parallel interfaces, and enables connection to various external apparatuses through a single unified interface. This multi-functionality allows the system to support multiple external devices without requiring separate connection infrastructure for each device type.
Solution Approach 2:
The conversion apparatus acts as an intermediary device between external apparatuses and the display apparatus. It receives various input signals from different external devices, converts them to the appropriate format, and transmits them to the display apparatus. This intermediary role simplifies the connection architecture by providing a single point of interface rather than requiring direct connections from multiple external devices to the display apparatus.
