Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display panel uses a uniform sub-pixel structure across the entire display area, then the manufacturing process is simple, but the display quality and image formation quality cannot be simultaneously optimized
Solution Approach 1:
The patent applies local quality by creating different sub-pixel structures in different regions of the display panel. The first display region contains first sub-pixels with a first structure optimized for display quality, while the second display region contains second sub-pixels with a second structure optimized for image formation quality. This allows each region to have specialized characteristics tailored to its specific function, resolving the contradiction between manufacturing simplicity and quality optimization.
Solution Approach 2:
The patent segments the display panel into multiple display regions with different sub-pixel configurations. By dividing the uniform display area into distinct regions (first display region and second display region), each with optimized sub-pixel structures, the patent achieves both display quality and image formation quality without requiring complete redesign of the entire panel, thus balancing manufacturing complexity with performance optimization.
2Manufacturing precision
If the display panel increases the area ratio of display sub-pixels to achieve higher screen-to-body ratio, then the display quality improves, but the image formation quality deteriorates due to reduced light transmittance
Solution Approach 1:
The patent applies local quality by creating different sub-pixel structures in different regions of the display panel. The first display region contains first sub-pixels with a first structure optimized for display quality, while the second display region contains second sub-pixels with a second structure optimized for image formation quality. This allows each region to have specialized characteristics tailored to its specific function, resolving the contradiction between manufacturing simplicity and quality optimization.

AI summary
An electronic device includes a photosensor and a display panel disposed on the photosensor. The display panel includes a first display region overlapping the photosensor and a second display region. The first display region includes first sub-pixels displaying a first color and second sub-pixels displaying a second color different from the first color. The second display region includes first sub-pixels displaying the first color and second sub-pixels displaying the second color. Along a first direction, a first gap between two adjacent first sub-pixels of the first display region is greater than a second gap between two adjacent first sub-pixels of the second display region. Along a second direction perpendicular to the first direction, a third gap between another two adjacent first sub-pixels of the first display region is greater than a fourth gap between another two adjacent first sub-pixels of the second display region.
