Light-Transmissive Display Layout for Under-Panel Module Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face complications in manufacturing processes due to the need for additional masks to create notches or free-form parts, which complicates the integration of elements like cameras, speakers, and sensors, increasing costs and time.
Innovation Solution
A display apparatus design that allows modules such as cameras, speakers, and sensors to be integrated into the active area without removing parts of the display panel, utilizing a bezel area for potential supply electrodes, and positioning gate and data lines to avoid module areas, enabling light transmission through a module region formed during the manufacturing process without separate masks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch or free-form part is created by cutting out a portion of the display panel edge, then elements such as camera, speaker, and sensor can be positioned in the removed region, but the manufacturing process becomes complicated due to the need for additional masks
Solution Approach 1:
The patent moves modules from the edge region (2D boundary) into the active area (2D interior space), utilizing the unused space within the display region. This dimensional repositioning allows modules to be integrated without requiring edge cutouts or additional masks, thereby maintaining manufacturing simplicity while achieving positioning flexibility.
Solution Approach 2:
The patent creates light-transmissive module areas with specific optical properties within the active area, allowing different regions of the display panel to have different functional qualities. The module areas are designed to transmit light while surrounding pixel areas maintain normal display functionality, enabling localized module integration without affecting overall display performance.
2Adaptability or versatility
If modules are positioned in a notch region formed by removing part of the display panel, then camera, speaker, and sensor elements can be integrated, but manufacturing time and cost increase due to additional masking steps
Solution Approach 1:
The patent merges the module area creation process with the existing display panel manufacturing process. The light-transmissive module areas are formed using the same manufacturing steps as the pixel areas, eliminating the need for separate masking operations. This integration reduces manufacturing time and maintains cost efficiency while enabling module integration.
3Adaptability or versatility
If gate lines and data lines are positioned to avoid module areas, then modules can be integrated in the active area, but the routing of signal lines becomes more complex
Solution Approach 1:
The patent segments the active area into pixel areas and light-transmissive module areas, with clear boundaries between them. This segmentation allows gate lines and data lines to be routed along the boundaries or through designated pathways, simplifying the routing logic. The segmented structure provides systematic guidance for signal line placement, reducing routing complexity despite the flexible module positioning.
