Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen display panels exhibit significant chromatic aberration between the camera area and display area, particularly in off-screen states, leading to reduced display effect and user experience.
Innovation Solution
A display module with a supporting layer containing a through hole in the camera area, equipped with a light-enhancing layer and anti-reflection layers to ensure consistent light transmission and reduce chromatic aberration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a through hole structure is used for under-screen camera in full-screen display panel, then camera function is realized and screen integrity is protected, but chromatic aberration between camera area and display area becomes obvious in off-screen state
Solution Approach 1:
The patent applies local quality by placing specific optical components (light-enhancing layer and anti-reflection layer) only in the camera area through hole, rather than uniformly across the entire display panel. The light-enhancing layer with reflective surface and anti-reflection layer are positioned at specific locations within the through hole to address the chromatic aberration problem locally where it occurs, without affecting other areas of the display panel.
Solution Approach 2:
The patent changes optical parameters by introducing a light-enhancing layer with specific reflective properties and an anti-reflection layer with controlled light transmission characteristics. These layers modify the light transmission parameters in the camera area, adjusting the optical path and reducing chromatic aberration to achieve better display consistency between the camera area and surrounding display area.
2Manufacturing precision
If under-screen camera technology is adopted, then black holes in camera area are reduced, but visual observation of camera area becomes possible in off-screen state reducing display effect
Solution Approach 1:
The patent converts the harmful effect of visible camera area in off-screen state into a benefit by using the light-enhancing layer with reflective surface. The reflective surface redirects light that would otherwise create visible dark areas or chromatic aberration, transforming the problematic through hole structure into an optical element that improves overall display uniformity while maintaining camera functionality.
Solution Approach 2:
The patent introduces an intermediary structure - the light-enhancing layer with anti-reflection coating - that mediates between the camera module and the display surface. This intermediary layer controls light interaction in the camera area, preventing direct visual observation of the camera structure while maintaining optical performance and reducing chromatic aberration.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances display consistency and overall performance by minimizing chromatic aberration between the camera and display areas, improving the visual experience.
Implementation Method 1
an anti-reflection layer is disposed on at least one light-transmitting surface of the light-enhancing layer
Implementation Method 2
the light-enhancing layer is disposed in the through hole, and an anti-reflection layer is disposed on at least one light-transmitting surface of the light-enhancing layer

AI summary
The display module and the display device provided by the embodiments of the present disclosure include a display panel and a supporting layer, the display module includes a light-enhancing layer, the light-enhancing layer is arranged in a through hole, and an anti-reflection layer is disposed on at least one light-transmitting surface of the light-enhancing layer. Under action of the light-enhancing layer and the anti-reflection layer, the light will make the display effect in the display area and the camera area be consistent, thereby reducing the chromatic aberration between different areas of the display panel and improving the display effect.
