Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional RGB sub-pixel arrangement is used, then manufacturing process is simple, but image brightness and white balance are insufficient
Solution Approach 1:
The sub-pixel array is segmented into alternating first sub-pixel rows (RGB) and second sub-pixel rows (BW), allowing different functional zones to coexist. This segmentation enables the display to achieve high brightness through white sub-pixels while maintaining color accuracy through RGB sub-pixels, resolving the contradiction between brightness enhancement and structural complexity.
Solution Approach 2:
The patent transitions from traditional single-row RGB arrangement to a two-dimensional alternating pattern of RGB and BW rows. This dimensional change allows the display to utilize both colored and white sub-pixels in a structured manner, improving overall brightness and white balance without requiring complete structural overhaul.
2Illumination intensity
If more white sub-pixels are added to improve brightness, then image brightness increases, but hardware cost increases
Solution Approach 1:
Instead of uniformly distributing white sub-pixels throughout the entire display, the patent applies them locally in alternating rows (second sub-pixel rows), while maintaining traditional RGB rows elsewhere. This local quality approach allows brightness enhancement in specific areas without proportionally increasing the total number of sub-pixels across the entire display, thereby controlling hardware costs.
3Manufacturing precision
If alternating RGB and BW sub-pixel rows are used, then image definition and white balance improve, but manufacturing complexity increases
Solution Approach 1:
The patent employs dynamic control methods where the display system adaptively switches between different sub-pixel row configurations and adjusts grayscale values based on image content requirements. This dynamic approach allows the system to optimize image definition and white balance through software control rather than requiring complex hardware modifications, thereby managing manufacturing complexity.
Solution Approach 2:
The patent utilizes parameter changes in the form of adjustable grayscale values for different sub-pixel rows. By dynamically adjusting the intensity parameters of RGB and BW sub-pixels based on image content, the system achieves improved image definition and white balance without requiring permanent structural changes, thus managing manufacturing complexity.
