Engineering Contradiction Analysis
1Speed
If the frame time is shortened to increase operation frequency, then the performance of electronic devices is enhanced, but the charging time of the signal channel becomes insufficient
Solution Approach 1:
The scan lines are divided into multiple groups, where each group shares common first and second scan lines. This segmentation allows the charging time to be distributed across multiple time periods, with each group being charged in sequence rather than all simultaneously, thus extending the effective charging time without increasing the overall frame time.
Solution Approach 2:
The patent implements periodic scanning and charging actions across multiple time periods. Different groups of scan lines are activated and charged in alternating time periods, creating a periodic pattern that extends the charging process over multiple cycles while maintaining the shortened frame time structure.
2Loss of time
If the resistance of the signal channel and capacitance of the modulating device are reduced to accelerate charging, then the charging time is shortened, but significant modification to the design and process is required, increasing design cost and manufacturing cost
Solution Approach 1:
The patent introduces dynamic control through multiple switches associated with each modulator and periodic activation of different scan line groups. This dynamic time-multiplexed approach allows the system to achieve extended charging time without modifying the physical resistance or capacitance values, avoiding costly design and process changes while maintaining fast charging performance.
