Display Panel Light Converging Member for Full-Screen Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current full-screen mobile phone designs face challenges in achieving a 100% screen ratio due to the need for a dedicated area to accommodate the front camera, limiting the screen ratio and making a full-screen design difficult to realize.
Innovation Solution
Incorporating a light transmitting hole in the display panel with a lens and a light-emitting element, along with a light converging member, to allow for image acquisition and display functionality, enabling the camera to be integrated within the screen while maintaining a full-screen display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated area is set on the front of the mobile phone to accommodate the front camera, then the front camera function is achieved, but the screen ratio is limited and full-screen design is difficult to realize
Solution Approach 1:
The patent embeds the front camera lens and light-emitting element within a light-transmitting hole of the display panel, nesting multiple functional components in a three-dimensional arrangement. The camera lens is positioned below the display panel while the light-emitting element is arranged above the lens, allowing both camera and display functions to coexist in the same spatial region without compromising screen ratio.
Solution Approach 2:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional spatial arrangement by placing the camera lens and light-emitting element at different depths (above and below the display panel). This vertical stacking approach allows both components to occupy the same footprint area while maintaining their respective functions, thereby achieving full-screen display without sacrificing camera capability.
2Adaptability or versatility
If a light transmitting hole is formed in the display panel to accommodate the camera, then the camera can be integrated within the screen, but the display effect at the hole position may be compromised
Solution Approach 1:
The patent introduces a light-emitting element as an intermediary component positioned above the camera lens within the light-transmitting hole. This light-emitting element fills the optical path and ensures that light can be properly emitted and displayed through the hole position, maintaining display continuity and effect uniformity across the entire screen including the area where the camera is integrated.
Solution Approach 2:
The patent applies local quality by specifically addressing the display requirements at the light-transmitting hole position. The light-emitting element is precisely positioned and configured to ensure that the display effect at this specific location matches the surrounding areas, maintaining overall display uniformity while accommodating the camera integration.
3Adaptability or versatility
If the light-emitting element and light converging member are arranged at the light transmitting hole, then both image acquisition and display functionality are achieved, but the device structure becomes more complex
Solution Approach 1:
The light-transmitting hole position serves multiple functions simultaneously: it accommodates the camera lens for image acquisition, houses the light-emitting element for display output, and maintains the display panel's optical path. This multi-functional design allows a single structural location to fulfill both camera and display requirements, reducing the need for separate dedicated areas for each function.
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
This solution allows for both image capturing and full-screen display functionality, optimizing the display effect by converging light emitted by the light-emitting element onto the lens, thus enhancing user experience and achieving a seamless full-screen design.
Implementation Method 1
a light-emitting element and a light converging member arranged at the light transmitting hole, wherein the light converging member is arranged at a side of the light-emitting element from which light is emitted, and is used for converging the light emitted by the light-emitting element on the lens
