Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light transmitting area has uneven width distribution, then the display panel can be manufactured with simpler structure, but diffraction occurs and optical sensing effect deteriorates
Solution Approach 1:
The patent applies local quality by making the light transmitting area have different width characteristics at different positions. Specifically, the width at the center point is made equal to the width at positions closer to the sides, creating a localized adjustment that reduces diffraction while maintaining overall structural simplicity. This targeted modification addresses the diffraction problem without requiring complete redesign of the entire light transmitting area.
2Ease of manufacture
If the light transmitting area has uneven width distribution, then manufacturing is easier, but optical sensing effect is reduced
Solution Approach 1:
The patent changes the geometric parameter (width) of the light transmitting area at specific positions. By adjusting the width at the center point to be equal to the width at positions closer to the sides, the patent optimizes the optical sensing effect. This parameter modification allows the same structural simplicity to coexist with improved optical performance, as the width adjustment is minimal and maintains manufacturing ease.
3Object-affected harmful factors
If the light transmitting area has symmetrical width configuration, then diffraction is reduced, but device complexity increases
Solution Approach 1:
The patent applies asymmetry in a subtle way by creating a specific width configuration where the center point width equals the side-adjacent width, while the overall light transmitting area maintains its functional asymmetry relative to the transistor and scan line. This controlled asymmetry adjustment reduces diffraction without requiring complete symmetrization of the entire structure, thus avoiding excessive complexity.

AI summary
An electronic device includes a first transistor, a first scan line electrically connected to the first transistor, and a light transmitting area adjacent to the first transistor. The light transmitting area includes a first side adjacent to the first scan line, and a center point. A first width of the light transmitting area at the center point is measured along a first direction, a second width of the light transmitting area at a position closer to the first side than the center point is measured along the first direction, and a third width of the light transmitting area at another position closer to the center point than the position is measured along the first direction. The first width is substantially equal to the third width, and the second width is less than the third width.
