Backlight Module Sealing Member for Camera Aperture Dust and Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel designs with opening holes for camera modules suffer from issues such as dust ingress, light interference, and reduced sealing and imaging effectiveness, which hinder the achievement of a full-screen display effect.
Innovation Solution
A backlight module is positioned on the non-emitting side of the display panel with a through hole for the camera, featuring a fixing member and sealing member that form an integral structure to seal the hole, using extension parts with varying thicknesses and a mounting groove for secure connection, ensuring minimal gap and effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an opening hole is provided in the backlight module for camera module installation, then the camera module can be positioned on the screen, but external dust will enter the backlight module through the opening hole
Solution Approach 1:
A sealing member is introduced as an intermediary component between the opening hole and the backlight module interior. The sealing member includes a sealing surface that contacts the opening hole and an inner surface that faces the backlight module, creating a barrier that prevents dust from entering while allowing the camera module to be installed through the opening hole.
2Adaptability or versatility
If an opening hole is provided in the backlight module, then the camera assembly can be placed in the opening hole, but light inside the display panel will enter the camera assembly through a gap at an edge of the opening hole
Solution Approach 1:
The sealing member acts as an intermediary structure that fills the opening hole and prevents light leakage. The sealing surface contacts the opening hole edge, and the inner surface extends into the backlight module, creating a light barrier that prevents display light from entering the camera assembly while maintaining the opening for camera installation.
3Ease of manufacture
If a simple opening hole structure is used, then manufacturing is easier, but sealing and imaging effectiveness are reduced
Solution Approach 1:
The opening hole structure is segmented into multiple functional components: the opening hole itself, the sealing member with distinct sealing surface and inner surface, and the camera module mounting structure. This segmentation allows each component to perform its specific function - the opening hole provides access, the sealing member provides dust and light barrier, and the mounting structure secures the camera module.
Solution Approach 2:
Different regions of the sealing member have different properties optimized for their specific functions. The sealing surface is designed to contact the opening hole for sealing, while the inner surface is positioned to prevent light leakage. The projection structure provides localized support and positioning for the camera module.
