Transparent Display Panel for Full-Screen Camera Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile display devices cannot achieve a screen-to-body ratio of 100% due to the presence of functional components like cameras, which limits their full-screen design and aesthetic appeal, and existing solutions like lifting cameras are non-waterproof and have low lifespan.
Innovation Solution
A display panel with a transparent display area and an opaque display area, utilizing a backlight, liquid crystal display panel, and polarizers, where the transparent area allows light passage for camera use and switches to image display, enhancing the screen-to-body ratio and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a lifting camera structure is used to achieve full-screen display, then the screen-to-body ratio is improved, but the device becomes non-waterproof and has low lifespan
Solution Approach 1:
The patent replaces the mechanical lifting camera structure with a transparent display technology. Instead of mechanically moving the camera module to achieve full-screen effect, the invention uses a transparent display panel that allows light to pass through the display area, enabling the camera to function through the screen without any mechanical movement. This substitution eliminates the mechanical components that compromise waterproofing and durability.
Solution Approach 2:
The patent utilizes optical property changes in the display material, specifically using transparent liquid crystal or transparent OLED materials that can change from opaque to transparent state. This allows the display area to become transparent when the camera needs to function, eliminating the need for mechanical opening while maintaining full-screen appearance and waterproof integrity.
2Reliability
If functional components like camera are placed on the screen, then basic functions are achieved, but the screen-to-body ratio cannot reach 100% and appearance is compromised
Solution Approach 1:
The patent merges the display function and camera function into a single integrated structure. The transparent display panel serves both as the display interface and as the window through which the camera operates. This merging eliminates the need for separate openings or notches for the camera, achieving true full-screen ratio while maintaining all functional components.
Solution Approach 2:
The transparent display area serves multiple functions: it acts as the display interface when opaque, and as a transparent window for the camera when transparent. This multi-functionality allows a single area to fulfill both display and camera access requirements, eliminating the need for separate structural elements and achieving 100% screen-to-body ratio.
