Screen Assembly Ink Layers Block Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in increasing the screen-to-body ratio of electronic devices is that smaller camera module holes restrict the field of view, leading to light leakage and visibility of internal structures, which affects both the camera's performance and aesthetics.
Innovation Solution
The use of ink layers with varying diameters and positions between the backlight module, display panel, and cover plate to block light leakage and shield internal structures, ensuring a larger camera field of view without obstructing external light, thereby enhancing the screen-to-body ratio and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the hole diameter is decreased to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the field of view of the camera module is blocked
Solution Approach 1:
The patent divides the hole structure into multiple segments: a first hole in the backlight module, a second hole in the display panel, and a third hole in the cover plate. These segmented holes with different diameters and positions allow the camera module to have a larger effective field of view while maintaining a small overall hole appearance on the screen surface, thus resolving the contradiction between screen-to-body ratio and field of view.
Solution Approach 2:
The patent extends the hole structure from a single-plane circular hole to a multi-dimensional configuration spanning multiple layers (backlight module, display panel, cover plate) with different diameters and orientations. This dimensional transformation allows light to pass through multiple offset holes, effectively increasing the camera's field of view without increasing the visible hole size on the screen.
2Area of stationary object
If the hole diameter is decreased to increase screen-to-body ratio, then the screen-to-body ratio is improved, but light leakage occurs affecting camera performance
Solution Approach 1:
The patent applies different hole diameters and ink layer configurations at different locations and layers. The first hole in the backlight module has a larger diameter than the second hole in the display panel, which is larger than the third hole in the cover plate. This local quality variation allows effective light blocking at each layer while maintaining overall high screen-to-body ratio.
Solution Approach 2:
The patent employs ink layers positioned between the holes of different modules to proactively block stray light before it can reach the camera module. This preliminary anti-action prevents light leakage that would otherwise degrade camera performance, allowing the use of smaller holes for high screen-to-body ratio without sacrificing shooting quality.
3Area of stationary object
If the hole diameter is decreased to increase screen-to-body ratio, then the screen-to-body ratio is improved, but internal structures become visible affecting aesthetics
Solution Approach 1:
The patent implements a nested structure where the first hole, second hole, and third hole are positioned concentrically or offset within each other across multiple layers. The ink layers are nested between these holes, creating a layered nesting configuration that effectively blocks views of internal structures while maintaining a clean external appearance with high screen-to-body ratio.

AI summary
A screen assembly and an electronic device are provided according to the disclosure. The screen assembly includes a backlight module, a display panel, a cover plate, and a camera module. The cover plate, the display panel, and the backlight module are stacked in sequence. The backlight module defines a mounting through hole for receiving the camera module. A first ink layer is sandwiched between the backlight module and the display panel. A second ink layer is sandwiched between the display panel and the cover plate. The first ink layer and the second ink layer cooperate with each other to block light leakage of the display panel and the backlight module toward the camera module. A technical solution of the disclosure is beneficial to increase a screen-to-body ratio of the electronic device and improve shooting performance of the camera module.
