Display Synchronization via Embedded Flags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display synchronization technologies require sending an additional synchronization short packet, which increases transmission duration and affects efficiency, leading to higher energy consumption and increased cabling complexity.
Innovation Solution
A method that eliminates the need for an additional synchronization short packet by encapsulating data blocks and synchronization flags within data packets, allowing the display module to determine the display location based on the synchronization flag, thus maintaining display synchronization without the need for extra synchronization packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional synchronization short packet is sent before display data, then display synchronization is achieved, but transmission duration increases and transmission efficiency decreases
Solution Approach 1:
The patent merges the synchronization function with the display data transmission by embedding a synchronization flag within each data packet. Instead of sending separate synchronization short packets, the synchronization information is combined with the display data blocks, allowing both synchronization and data transmission to occur simultaneously in a single transmission sequence, thereby eliminating the additional transmission duration.
2Reliability
If an additional synchronization short packet is sent before display data, then display synchronization is achieved, but energy consumption increases
Solution Approach 1:
The patent combines synchronization signaling with display data transmission by incorporating a synchronization flag into each data packet. This merging eliminates the need for separate synchronization short packets, reducing the number of transmission operations and allowing the system to remain in low-power states longer, thereby reducing overall energy consumption while maintaining display synchronization.
3Reliability
If dedicated signal lines or bidirectional transmission lines are used to transmit synchronization flags, then display synchronization is achieved, but cabling complexity and costs increase
Solution Approach 1:
The patent makes the data transmission line universal by enabling it to carry both display data and synchronization information through the synchronization flag embedded in each data packet. This eliminates the need for dedicated synchronization signal lines or bidirectional transmission lines, as the unidirectional data line performs multiple functions: transmitting both synchronization commands and display data, thereby reducing cabling complexity and costs.
Data Source
AI summary
A method includes: a processor that obtains several lines of data in to-be-displayed display data to generate a data block; generates a synchronization flag corresponding to the data block; encapsulates the data block and the synchronization flag corresponding to the data block to obtain a data packet corresponding to the data block; and sends all data packets corresponding to the display data to the display system. The display system sequentially parses all the data packets sent by the processor to obtain a synchronization flag associated with each data packet, and determines a display location of each data block on a display panel based on the synchronization flag to display the display data.
