Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex algorithm is used for power saving operation, then power consumption estimation accuracy is improved, but calculation complexity and processing time increase
Solution Approach 1:
The patent segments the channel data into multiple groups (first channel groups and second channel groups) and processes them separately. This segmentation allows the system to calculate power consumption for different channel groups independently, reducing the overall calculation complexity while maintaining estimation accuracy through targeted analysis of each group's characteristics.
Solution Approach 2:
The patent applies different processing methods to different channel groups based on their specific characteristics. First channel groups are processed to determine drive currents based on gray scale value differences, while second channel groups are processed to determine transient values. This local quality approach allows optimized power estimation for each group type without requiring complex unified algorithms.
2Device complexity
If a simple algorithm is used for power saving operation, then calculation complexity is reduced, but power consumption estimation accuracy deteriorates
Solution Approach 1:
By dividing channel data into multiple groups with distinct processing methods, the patent achieves simple yet accurate power estimation. Each group is processed using a straightforward method appropriate to its characteristics, avoiding the need for complex unified algorithms while maintaining overall estimation accuracy through the combined results of simple group-level calculations.
Solution Approach 2:
The patent changes the parameters used for calculation based on channel group type. For first channel groups, gray scale value differences are used to determine drive currents, while for second channel groups, transient values are calculated from data changes. This parameter adaptation allows simple algorithms to achieve accurate power estimation by selecting appropriate parameters for each group type.
3Use of energy by stationary object
If power saving operation is implemented for all channel groups, then power consumption is reduced, but display quality and responsiveness may deteriorate
Solution Approach 1:
The patent segments channel groups into first and second groups with different power saving strategies. First channel groups use drive current optimization based on gray scale differences, while second channel groups use transient value-based power saving. This segmentation allows selective power saving that maintains display quality by applying appropriate methods to each group type.
Solution Approach 2:
The patent dynamically determines power saving operations based on calculated transient values and gray scale value differences. The system adapts its power saving strategy in real-time based on the actual data characteristics of each channel group, ensuring that power saving does not compromise display quality or responsiveness.

AI summary
A driving method includes: allocating multiple pieces of channel data to multiple first channel groups and multiple second channel groups; determining, based on the multiple pieces of channel data, a largest gray scale value difference of two adjacent pieces of channel data of each of the first channel groups, to determine multiple drive currents; or determining, based on a first piece of data and a second piece of data that correspond to each of the multiple second channel groups in the multiple pieces of channel data, a first transient value and a second transient value that correspond to each of the multiple second channel groups, where the multiple drive currents are used to drive the first channel groups; and determining, based on the first transient value and the second transient value, whether at least one of the second channel groups performs a power saving operation.
