Display Panel Groove Light Refraction for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies cannot achieve a full screen display due to the need for camera notches and holes, which obstruct the incoming light required for camera functionality, and there is a lack of effective integration of camera areas with imaging regions.
Innovation Solution
A display panel design featuring an imaging area with a groove for camera light entry, an LED lamp plate, a light controlling layer with refracting structures, and a liquid crystal structural layer that allows light to be refracted into the groove, ensuring adequate light for camera use while enabling full-screen display when the camera is off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a groove is provided in the imaging area to allow light entry for camera, then the amount of incoming light for camera photographing is improved, but the display quality and full-screen effect may deteriorate due to the interruption in the display area
Solution Approach 1:
The light controlling layer acts as an intermediary component between the display area and the groove. It selectively controls light transmission: allowing light to pass through the groove area to the camera while blocking light in the surrounding display areas to maintain display quality. This mediator approach resolves the contradiction by enabling both sufficient light entry and preserved display effect.
Solution Approach 2:
The light controlling layer implements local quality differentiation: it has different optical properties in different regions. The area corresponding to the groove has high light transmission to enable camera function, while the surrounding areas have light blocking properties to maintain display integrity. This local differentiation allows the system to simultaneously achieve both contradictory requirements.
2Adaptability or versatility
If the LED lamp plate is configured above the camera and on two sides of the groove, then the imaging area can display images when the camera is turned off, but the light distribution uniformity may worsen due to the groove interruption
Solution Approach 1:
The light controlling layer serves as a mediator that redistributes light from the LED lamp plate. It receives light from LEDs positioned on both sides of the groove and selectively directs it: blocking light that would create uneven distribution while allowing controlled light transmission through the groove area. This mediation achieves uniform light distribution across the display area while preserving the dual functionality of the imaging region.
3Adaptability or versatility
If the light controlling layer with refracting structures is used to refract light into the groove, then the display panel can normally display images when the camera is not in operation, but the manufacturing precision requirements increase due to the refracting structure complexity
Solution Approach 1:
The refracting structures are designed with specific geometric parameters (arc radius, depth, spacing) that optimize light refraction into the groove while maintaining manufacturability. By carefully selecting these parameters, the patent achieves effective light redirection for camera-off display function without requiring excessively tight manufacturing tolerances. The parameter optimization balances performance with manufacturing feasibility.
4Illumination intensity
If the groove extends from the LED lamp plate to the surface of the liquid crystal structural layer, then light can effectively reach the camera, but the structural integrity of the display panel may deteriorate due to the through-hole
Solution Approach 1:
The light controlling layer is implemented as a thin film structure that can be flexibly positioned and shaped. This thin film approach allows the groove to extend through the panel while maintaining structural integrity, as the flexible film can conform to the groove geometry without creating weak points. The thin film nature provides sufficient mechanical strength while enabling effective light transmission to the camera.
