Optical Fiber Light Guiding Structure for Full-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen display devices face challenges in integrating off-screen camera shooting and image acquisition without compromising the display function, as traditional designs either lose display functionality or provide a suboptimal user experience due to the placement of lenses through openings.
Innovation Solution
A light guiding structure comprising a housing with a first optical fiber structure to transmit light to an image collection module and a second optical fiber structure to transmit images from an image compensation module, allowing for image acquisition and display through optical fibers arranged under the display screen, effectively mimicking the placement of sensors and cameras without obstructing the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lens or camera is placed through an opening in the display screen, then image acquisition function is achieved, but the display functionality is lost or user experience is compromised
Solution Approach 1:
The patent introduces optical fibers as an intermediary medium to transmit light between the opening and the image collection module. The optical fibers enable image acquisition without requiring a physical lens to protrude through the screen, thus maintaining the display's integrity and full-screen functionality while achieving off-screen camera capability
Solution Approach 2:
The patent moves the image collection module from a traditional front-facing position to a position beneath the display screen. By using optical fibers to transmit light from the opening through the display to the sensor located underneath, the system achieves image acquisition in a different spatial dimension without compromising the display surface
2Ease of operation
If the display screen maintains full coverage, then display quality is improved, but integration of image acquisition components becomes difficult
Solution Approach 1:
The patent embeds the image collection module and optical fiber structure within the display device's housing, beneath the display screen. The optical fibers are routed through the display layers to reach the opening, nesting the imaging components within the existing display structure without requiring separate housings or external protrusions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables real full-screen display functionality while allowing for image acquisition and display, enhancing user experience by maintaining the screen's functionality and resolution, and addressing the limitations of traditional 'bangs' or 'beauty arch' designs.
Implementation Method 1
a first optical fiber structure (3'), an image collection module (4'), a second optical fiber structure (6'), and an image compensation module (7') in the housing (1). The first optical fiber structure (3') is configured to transmit light incident into the opening (2) to the image collection module (4')
Implementation Method 2
the second optical fiber structure (6') is configured to transmit an image displayed by the image compensation module (7') to the opening (2)
Implementation Method 3
the image collection module comprises a convex lens configured to focus light transmitted by the first optical fiber structure to the photosensitive sensor
