Solution Overview

Problem

Smartphones and similar devices have a low screen-to-body ratio, leading to poor user experience due to limited space for image capture without compromising display functionality.

Innovation Solution

Incorporating a transparent entity area on the display screen assembly that allows light to pass through for image capture, enabling the camera to capture external scenes while maintaining display functionality, and using a processor to remove internal scenes from the image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a physical opening is made in the display screen for image capture, then the camera can capture external scenes, but the display integrity and aesthetic appeal deteriorate

Engineering Contradiction:
Improveimage capture capabilityVSAvoiddisplay integrity
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The display screen is divided into a transparent entity area and a non-transparent area, allowing different regions to serve different functions. The transparent area enables light transmission for image capture while the non-transparent area maintains display integrity and aesthetics.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the display screen are assigned different optical properties. The transparent entity area has high light transmittance for camera access, while surrounding areas maintain normal display properties, creating localized functional zones within the unified display structure.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the display screen is made fully transparent for image capture, then the camera can capture through the screen, but the display functionality and visibility deteriorate

Engineering Contradiction:
Improvelight transmission for image captureVSAvoiddisplay visibility
Core Design Contradiction:
Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The display screen is segmented into transparent and non-transparent regions, allowing simultaneous optimization of light transmission in the transparent area for image capture and light emission in the non-transparent area for display visibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display screen can dynamically adjust its transparency characteristics. The transparent entity area can switch between transparent and opaque states, allowing the system to adapt between image capture mode and normal display mode as needed.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the transparent entity area is made larger for better image capture, then more light can pass through, but the display area and screen-to-body ratio deteriorate

Engineering Contradiction:
Improvelight transmission areaVSAvoiddisplay area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The transparent entity area is strategically positioned and sized to provide sufficient light transmission for image capture while minimizing impact on the overall display area. The local transparency is optimized for camera functionality without compromising the global display properties.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The transparent entity area is positioned in a region that does not significantly reduce the effective display area. By utilizing the spatial arrangement and positioning the transparent area in a less critical display zone, the screen-to-body ratio is maintained while still providing adequate light transmission.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Illumination intensity

If the display screen maintains full opacity for better display contrast, then display quality improves, but image capture capability without openings deteriorates

Engineering Contradiction:
Improvedisplay contrastVSAvoidimage capture capability
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The display screen is segmented into functional zones: transparent entity areas for image capture and non-transparent areas for high-contrast display. This segmentation allows each zone to be optimized for its specific function without compromising the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display screen serves multiple functions simultaneously: it acts as both a display device and a light transmission window for the camera. The transparent entity area enables the display screen to fulfill dual roles, combining display functionality with image capture assistance.

Inventive Principle:
Principle #6Universality (Multi-functionality)
