Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a uniform color filter arrangement is used across all regions, then manufacturing is simple, but light transmittance becomes inconsistent across different regions affecting display quality and module performance
Solution Approach 1:
The patent applies local quality by configuring color filters differently in different regions of the display panel. Specifically, a first color filter is disposed in a first region overlapping a first pixel, while a second color filter is disposed in a second region overlapping a second pixel and a third pixel. This regional differentiation optimizes light transmittance for both display pixels and sensor pixels, resolving the contradiction between manufacturing simplicity and light transmittance uniformity.
2Illumination intensity
If color filters are optimized for display pixels, then display quality improves, but light transmittance to sensor modules deteriorates
Solution Approach 1:
The patent implements local quality by creating region-specific color filter configurations. The first color filter in the first region is optimized for display pixel performance, while the second color filter in the second region is optimized for sensor module light reception. This allows simultaneous optimization of display brightness and sensor performance without compromise.
Solution Approach 2:
The patent applies segmentation by dividing the display panel into multiple regions with different color filter configurations. The panel is segmented into a first region with a first color filter and a second region with a second color filter, enabling independent optimization of optical properties for different functional areas.
3Manufacturing precision
If the shape of color filters matches the shape of light emission elements, then manufacturing precision is improved, but device complexity increases due to multiple shape variations
Solution Approach 1:
The patent applies local quality by allowing different color filter shapes in different regions. The first color filter has a shape corresponding to the first light emission element, while the second color filter has a shape corresponding to the second and third light emission elements. This regional adaptation achieves precise alignment without requiring a single complex universal shape.

AI summary
An electronic device includes a display panel including a first region, a second region, a third region, and a reflection prevention optical layer. A first light emission element is disposed in the first region, a second light emission element is disposed in the second region, and a third light emission element is disposed in the third region. The reflection prevention optical layer includes a first color filter overlapping the first light emission element, a second color filter overlapping the second light emission element, and a third color filter overlapping the third light emission element. The first color filter, the second color filter, and the third color filter transmit light of the same color, and the shape of the first color filter is different from the shape of the second color filter and the shape of the third color filter.
