Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in increasing the screen-to-body ratio while maintaining effective camera photography and display effects, particularly with the 'water drop screen' design, which complicates internal structures and increases manufacturing costs.
Innovation Solution
A display panel design featuring a first display region with higher light transmittance than a second display region, where the first region includes sub-pixels arranged in a specific pattern and connected through transparent conductive data lines, allowing for both display functionality and camera operation without compromising the camera's photographing effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a water drop screen design is used to increase the body-to-screen ratio, then the screen-to-body ratio is improved, but the internal structure complexity increases and manufacturing cost increases
Solution Approach 1:
The display area is segmented into a first display region with higher light transmittance and a second display region with lower light transmittance. This segmentation allows the front camera to be positioned under the high-transmittance region while maintaining display functionality in both areas, thereby achieving a high screen-to-body ratio without complex mechanical structures.
Solution Approach 2:
The first display region serves dual functions: it acts as both a display area and a light-transmitting region for the under-screen camera. This multi-functionality eliminates the need for separate mechanical structures like lift cameras or sliding mechanisms, simplifying the overall device structure while maintaining high screen-to-body ratio.
2Area of moving object
If a water drop screen design is used to increase the body-to-screen ratio, then the screen-to-body ratio is improved, but the manufacturing cost increases
Solution Approach 1:
The display is divided into regions with different light transmittance characteristics, allowing the front camera to be integrated under the screen without requiring complex mechanical structures. This segmentation can be achieved through standard display manufacturing processes, avoiding additional manufacturing steps and costs associated with lift or sliding mechanisms.
3Area of moving object
If a digging hole full screen design is used to increase the body-to-screen ratio, then the original body structure is kept unchanged, but the overall visual experience is affected
Solution Approach 1:
Different regions of the display have different light transmittance properties: the first display region has higher light transmittance for camera operation, while the second display region has lower light transmittance for optimal visual display. This local differentiation ensures that the digging hole is not visually noticeable while maintaining both display quality and camera functionality.
4Reliability
If the light transmittance of the first display region is increased to improve camera photographing effect, then the camera photographing effect is improved, but the display effect in the first region may be compromised
Solution Approach 1:
The display is designed with spatially varying light transmittance: the first display region has higher light transmittance to improve camera photographing effect, while the second display region has lower light transmittance to maintain optimal display brightness and visual quality. This local quality differentiation resolves the contradiction between camera performance and display effect.
