Engineering Contradiction Analysis
1Speed
If dynamic capacitance compensation method is used to increase liquid crystal response speed, then response speed is improved, but manufacturing cost increases due to memory device requirement
Solution Approach 1:
The patent extracts and eliminates the memory device from the dynamic capacitance compensation system by implementing a lookup table directly within the data driving circuit, thereby removing the need for separate memory components while maintaining the response speed improvement
Solution Approach 2:
The patent merges the lookup table functionality with the data driving circuit, combining what were previously separate components (memory device and data driver) into an integrated structure that reduces overall system complexity and manufacturing cost
2Speed
If memory device is used for storing lookup table in dynamic capacitance compensation, then liquid crystal response speed is improved, but device complexity increases
Solution Approach 1:
The patent merges the lookup table storage function with the data driving circuit operations, eliminating the need for separate memory device and reducing overall device complexity while maintaining the capability for dynamic capacitance compensation
Solution Approach 2:
The data driving circuit is designed to perform multiple functions: it stores the lookup table, performs luminance difference calculation, and drives the data lines, thereby eliminating the need for dedicated memory components and reducing overall system complexity
