Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a light-shielding structure array is added to improve imaging quality, then light diffraction is reduced, but device complexity increases
Solution Approach 1:
The light-shielding structure array divides the light path into multiple controlled segments, with each light-shielding structure creating specific diffraction patterns that collectively improve imaging quality while managing complexity through modular repetition
Solution Approach 2:
The light-shielding structures are designed with asymmetric orientations at different angles within the array, creating controlled diffraction effects that reduce overall light diffraction interference while maintaining a relatively simple repeating unit structure
2Measurement precision
If light-shielding structures are oriented at different angles to increase diffraction directions, then imaging quality improves, but manufacturing precision requirements increase
Solution Approach 1:
Different regions of the light-shielding structure array have structures oriented at different angles, with each local region optimized for specific diffraction control needs while maintaining overall system performance through coordinated local variations
Solution Approach 2:
The orientation angle of light-shielding structures is varied as a controlled parameter across the array to optimize diffraction patterns, allowing systematic adjustment of imaging quality while managing manufacturing precision through defined angle specifications

AI summary
The present disclosure provides a display panel and a display device including the display panel. The display panel has a display region including a first display region and a second display region, and the first display region has a smaller sub-pixel density than the second display region. Light-shielding structures are arranged in the first display region, and one light-shielding structure overlaps a light-emitting region of at least one first sub-pixel. The light-shielding structure group constituted by the light-shielding structures includes main and auxiliary light-shielding structures having the same shape. When viewed from the top at the same viewing angle, the auxiliary light-shielding structure is equivalent to a structure obtained by rotating the main light-shielding structure by a certain angle in a plane where the main light-shielding structure is located. With this design, a light diffraction phenomenon is alleviated and the imaging quality of the under-screen optical device is improved.
