Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with integrated optical electronic devices, such as cameras or sensors, face challenges in maintaining a large display area while accommodating these components without exposing them on the front surface, leading to reduced transmittance and design constraints.
Innovation Solution
A display device design with distinct optical and normal areas, where optical areas include light transmission structures and share signal lines with normal areas, allowing optical devices to be positioned under the display panel, thus maintaining high transmittance and concealing them from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical electronic devices are installed on the front surface of the display panel, then the devices can be easily accessed and functionally integrated, but the display area is reduced and the appearance is compromised due to visible notches or holes
Solution Approach 1:
The patent relocates optical electronic devices from the front surface (2D plane) to the rear side of the display panel, utilizing the third dimension (depth) to resolve the conflict between functional integration and display area maintenance. This allows full display area while accommodating camera and sensor functions.
Solution Approach 2:
The optical electronic devices are nested within the display panel structure itself, specifically positioned in the rear side substrate. The display panel acts as a container that houses both display functionality and optical electronic components without requiring separate external structures.
2Area of stationary object
If optical electronic devices are positioned under the display panel, then the display area is maximized and appearance is improved, but light transmission to the devices becomes insufficient without additional transmission structures
Solution Approach 1:
The rear side substrate is segmented into distinct regions: light emitting areas for display and light transmission areas for optical devices. This segmentation allows simultaneous optimization of both display quality and light transmission to hidden optical components.
Solution Approach 2:
Light transmission structures act as intermediary elements between the front surface and rear-side optical devices. These structures facilitate light passage through the display panel to reach the optical electronic devices positioned on the rear side.
3Adaptability or versatility
If signal lines are extended into the optical area to support hidden devices, then electrical connectivity is improved, but light transmission is blocked and display quality deteriorates
Solution Approach 1:
The patent applies different properties to different regions: the optical area contains both light transmission structures and signal lines, with the signal lines strategically positioned to minimize light blockage. The normal area has standard signal line distribution without transmission structures.
Solution Approach 2:
Signal lines are segmented into multiple sections with connection portions that route electrical signals around light transmission areas. This allows electrical connectivity to optical devices while preserving light paths through dedicated transmission zones.
