Embedded Sensor Display Panel for High Screen Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile display products face a constraint in achieving a high screen occupation ratio due to the need for a significant distance between the screen and the frame to accommodate camera units, which reduces the integration of other components and affects the display area.
Innovation Solution
The integration of sensors, such as front and rear camera units, into a receiving portion on the display panel, specifically through holes or grooves, allows for their embedding, eliminating the need for external space, thereby reducing the non-display region and increasing the screen occupation ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a significant distance is maintained between the screen and frame to accommodate camera units, then camera functionality is ensured, but screen occupation ratio decreases
Solution Approach 1:
The sensor is embedded into a receiving portion formed on the display panel, nesting the camera component within the display structure itself. This eliminates the need for external space while maintaining camera functionality, thereby resolving the contradiction between accommodating camera units and maximizing screen occupation ratio.
Solution Approach 2:
The invention transitions from a planar arrangement where sensors are placed outside the display panel to a three-dimensional embedding approach. By creating a receiving portion that extends into the display panel thickness, the sensor is positioned in an additional dimension, allowing camera functionality without compromising the front surface area for display.
2Area of stationary object
If sensors are integrated into the display panel, then screen occupation ratio increases, but manufacturing complexity increases
Solution Approach 1:
The display panel is segmented into functional regions, with a specific receiving portion dedicated to housing the sensor. This segmentation allows the sensor to be integrated at a specific location without requiring complete redesign of the entire display structure, thereby managing manufacturing complexity while achieving high screen occupation ratio.
Solution Approach 2:
The receiving portion serves multiple functions: it houses the sensor, maintains structural integrity of the display panel, and does not obstruct the display area. This multi-functionality reduces the need for additional components or structures, simplifying the overall manufacturing process despite the integration complexity.
3Device complexity
If sensors are embedded into the display panel, then component integration is enhanced, but camera functionality may be obstructed
Solution Approach 1:
The sensor is nested within a receiving portion that is specifically designed to accommodate the sensor while maintaining optical pathways and functional access. This nesting approach enhances component integration by embedding the sensor within the display panel structure, while the receiving portion geometry ensures that camera functionality is not obstructed.
Solution Approach 2:
The receiving portion is designed with local quality variations - specific regions have different transparency, thickness, or structural properties to optimize both sensor housing and camera function. This localized customization allows the embedded sensor to maintain full camera functionality while achieving high component integration within the display panel.
