Solution Overview
Problem
The communication efficiency of chain systems comprising multiple interconnected devices via data cables is low, failing to meet current demands.
Innovation Solution
A processing method where a first display device outputs trigger information to a second display device upon meeting a trigger condition, obtaining and transmitting their respective identification information to an electronic device, which represents the connection sequence of the display devices, enabling efficient data transmission and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are connected in a chain structure via data cables, then device interconnection is achieved, but communication efficiency deteriorates
Solution Approach 1:
The system performs preliminary actions by establishing identification information exchange and connection sequence determination before actual data transmission. The first display device obtains its own identification information and the second display device's identification information in advance, enabling the electronic device to pre-establish the communication topology and optimization strategies, thus improving subsequent communication efficiency.
2Measurement precision
If identification information exchange is implemented between display devices, then connection sequence determination is improved, but system complexity increases
Solution Approach 1:
The system segments the identification information into distinct components: first identification information representing the first display device and second identification information representing the second display device. This segmentation allows the electronic device to clearly distinguish device identities and positions in the chain, improving connection sequence determination while maintaining manageable system complexity through structured information organization.

AI summary
A processing method includes: outputting, by first display device, trigger information to a second display device in response to a trigger condition being met; obtaining, by the first display device, second identification information output by the second display device in response to the trigger information; obtaining, by the first display device, first identification information of the first display device; and transmitting, by the first display device, the first identification information and the second identification information to an electronic device, the first identification information and the second identification information representing a connection sequence of the first display device and the second display device. The electronic device, the first display device, and the second display device are connected in sequence, and the first display device obtains first image data from the electronic device and transmits part or all of the first image data to the second display device.
