Engineering Contradiction Analysis
1Device complexity
If a single driving voltage source is used for all sub-pixels, then device complexity is reduced, but power consumption increases and interference between sub-pixels occurs
Solution Approach 1:
The patent divides the single driving voltage source into multiple separate driving voltage sources (first driving voltage source for red sub-pixels, second driving voltage source for green sub-pixels, third driving voltage source for blue sub-pixels). This segmentation allows each color sub-pixel to receive independently optimized driving voltages, reducing power consumption and eliminating interference between sub-pixels while maintaining manageable device complexity through modular architecture.
2Device complexity
If a single driving voltage source is used for all sub-pixels, then device complexity is reduced, but interference between sub-pixels occurs
Solution Approach 1:
The patent segments the driving voltage generation into separate circuits for each color sub-pixel type. The first driving voltage source is dedicated to red sub-pixels, the second to green sub-pixels, and the third to blue sub-pixels. This segmentation prevents voltage interference between different color channels while maintaining clear signal integrity for each sub-pixel type.
3Device complexity
If driving voltage is not optimized for each sub-pixel type, then device complexity is reduced, but power consumption increases
Solution Approach 1:
The patent implements local quality optimization by providing different driving voltage characteristics to different color sub-pixels. The first driving voltage source provides voltages optimized for red sub-pixels, the second for green sub-pixels, and the third for blue sub-pixels. This localized optimization ensures each sub-pixel operates at peak efficiency with minimal energy loss, while the modular voltage source architecture keeps overall device complexity manageable.
