Engineering Contradiction Analysis
1Reliability
If periodic pulse signals are transmitted to synchronize timing between processor and display driver circuitry, then display quality and service efficiency are improved, but device complexity increases
Solution Approach 1:
The patent implements periodic pulse signal transmissions from the processor to the display driver circuitry to synchronize timing. This periodic action establishes a reliable timing reference without requiring complex continuous synchronization mechanisms, thereby improving display quality while managing system complexity through simple, repeated signals rather than complex continuous coordination
Solution Approach 2:
The emission synchronization signal serves as a feedback mechanism where the display driver circuitry informs the processor of its timing state. This feedback loop enables adaptive refresh rates and improves display quality by allowing the processor to adjust image transmission timing based on actual display driver readiness, while the feedback structure itself is integrated into existing communication protocols rather than adding significant complexity
2Productivity
If adaptive refresh rates are implemented for initial image display, then service efficiency is improved, but timing synchronization difficulty increases
Solution Approach 1:
The emission synchronization signal acts as an intermediary that mediates between the processor and display driver circuitry timing systems. This intermediary signal simplifies timing synchronization for adaptive refresh rates by providing a clear, standardized reference point that both sides can use to coordinate image transmission, thereby improving service efficiency without significantly increasing timing detection and measurement difficulty
Solution Approach 2:
The periodic pulse signals are transmitted before the actual image transmission occurs, establishing timing synchronization in advance. This preliminary action ensures that when adaptive refresh rates are activated for initial image display, the timing infrastructure is already in place, allowing efficient service delivery without the added complexity of real-time timing coordination
