Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device operates at high frame frequency to meet diverse application scene requirements, then the adaptability and display performance are improved, but the power consumption increases
Solution Approach 1:
The display panel is divided into multiple independent display blocks, each with its own driving module. This segmentation allows different blocks to operate at different frame frequencies simultaneously, enabling the system to adapt to diverse application scenes while consuming power only where and when needed, rather than forcing the entire display to run at high frame frequency.
Solution Approach 2:
The system dynamically adjusts the frame frequency of each display block independently based on the specific requirements of different application scenes. The control module can set different frame frequencies for different display blocks in real-time, optimizing power consumption while maintaining the required display performance for each scene.
2Adaptability or versatility
If the display device uses a single frame frequency for all display blocks, then the device complexity is reduced, but the adaptability to different application scenes is limited
Solution Approach 1:
Each display block is equipped with an independent driving module containing shift register, latch, level converter, decoder, digital-to-analog converter, and operational amplifier. This segmentation enables each block to be controlled independently with different frame frequencies, achieving diverse display capabilities while keeping each individual driving module's design relatively simple and standardized.
Solution Approach 2:
The driving modules use standardized components (shift register, latch, level converter, decoder, DAC, operational amplifier) that can be universally applied to different display blocks. This universal design allows the system to achieve multi-functionality and adaptability without proportionally increasing device complexity, as the same module design can serve multiple blocks with different frame frequency requirements.
