1Area of stationary object
If data packets are transmitted to multiple display devices, then the display coverage is improved, but phase differences and skew phenomena occur due to inconsistent impedance matching or path lengths
Solution Approach 1:
The phase detection unit continuously monitors the phase of synchronous signals from multiple data packets and feeds this information back to the signal reconstruction unit. The system uses this feedback to dynamically adjust and reconstruct synchronous signals, ensuring that phase differences are compensated in real-time, thereby maintaining synchronization accuracy across multiple display devices.
Solution Approach 2:
The signal reconstruction unit acts as an intermediary between the phase detection unit and the transmission units. It receives asynchronous synchronous signals, reconstructs them into synchronized signals by compensating for phase differences, and then transmits these reconstructed signals to the transmission units for synchronized display across multiple devices.
2Speed
If synchronous signals are transmitted without phase compensation, then the transmission speed is maintained, but skew phenomena cause user discomfort
Solution Approach 1:
The system performs preliminary phase detection on incoming synchronous signals before they are transmitted to display devices. By detecting and compensating for phase differences in advance through the signal reconstruction unit, the system ensures that synchronous signals are corrected before transmission, thereby eliminating skew phenomena without compromising transmission speed.
3Manufacturing precision
If phase detection and signal reconstruction are implemented, then synchronization accuracy is improved, but device complexity increases
Solution Approach 1:
The phase detection unit and signal reconstruction unit are designed as integrated components that can handle multiple data packets simultaneously. These units serve multiple functions: detecting phase differences, reconstructing synchronous signals, and compensating for variations in impedance matching and path lengths. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while maintaining high synchronization accuracy.
