Solution Overview
Problem
Conventional display apparatuses require additional masks and complex manufacturing processes to create notch portions for modules like cameras and sensors, which increases costs and reduces design flexibility.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch portion is formed by cutting out a portion of the display panel edge, then modules such as camera and sensor can be positioned in the notch, but an additional mask must be used which increases manufacturing complexity and cost
Solution Approach 1:
The invention extracts the light-blocking function from the physical notch structure and relocates it to a virtual light-blocking layer formed by the pixel array itself. By setting pixels surrounding the module area to a light-blocking state, the physical cutting and additional masking are eliminated, thereby reducing manufacturing complexity while maintaining module placement flexibility
Solution Approach 2:
The pixel array serves multiple functions: it displays image information in the active area and simultaneously creates the light-blocking effect for module protection without requiring separate components. The same pixel structure that displays images also provides the light-blocking function traditionally requiring additional masks, thereby simplifying the overall device structure
2Adaptability or versatility
If a notch portion is formed by cutting out the display panel, then modules can be disposed in the notch region, but light from the display or outside can still interfere with the modules
Solution Approach 1:
The invention introduces a light-blocking layer formed by pixel arrays as an intermediary between the light sources (display or external) and the modules. This intermediary layer selectively blocks harmful light from reaching the modules while allowing the modules to be integrated in the notch region, thereby solving the light interference problem without compromising module integration capability
Solution Approach 2:
The pixel arrays exhibit different optical properties in different regions: pixels in the active area maintain normal light transmission for display, while pixels surrounding the module area are set to light-blocking state to protect modules. This local differentiation of pixel properties enables selective light blocking to prevent interference while maintaining display functionality
3Object-affected harmful factors
If additional masks are used to create notch portions, then modules can be positioned without light interference, but manufacturing costs and process complexity increase
Solution Approach 1:
The pixel array is designed to perform dual functions: image display in the active area and light blocking for module protection. By utilizing the existing pixel structure for both purposes, the invention eliminates the need for additional masks, thereby maintaining light interference protection while simplifying the manufacturing process and reducing costs
Solution Approach 2:
The invention merges the light-blocking function traditionally performed by separate masks into the pixel array structure itself. The pixel arrays that normally display images are additionally utilized to create the light-blocking effect around modules, combining multiple functions into a single component and eliminating redundant manufacturing steps
