Integrated Camera Window for Glare-Free Imaging
Here’s PatSnap Eureka !
Summary
Problems
Portable electronic devices face challenges in integrating cameras effectively due to issues with glare and image quality, particularly when using glass cover arrangements, which often lack sufficient illumination and suffer from veiling glare.
Innovation solutions
The integration of a camera window into the cover glass with an optical barrier perimeter reduces glare by interposing a layer between the camera and the adjacent glass region, enhancing image quality and incorporating chemically strengthened glass for added durability.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a glass cover is used to protect the display, then scratch resistance and protective barrier are improved, but glare at the camera is increased
Why choose this principle:
The glass cover is segmented into distinct functional regions: a transparent camera window area and a darkened peripheral area. This segmentation allows the camera region to maintain transparency for clear imaging while the peripheral region provides glare reduction through darkening, resolving the contradiction between protective glass properties and glare reduction needs.
Principle concept:
If a glass cover is used to protect the display, then scratch resistance and protective barrier are improved, but glare at the camera is increased
Why choose this principle:
Different regions of the glass cover are assigned different optical properties. The camera window region remains transparent to allow light transmission for imaging, while the peripheral region is darkened to block stray light and reduce glare. This local differentiation of properties enables simultaneous achievement of transparency and glare reduction.

Abstract
Apparatus, systems and methods for camera integration with cover glass and for processing cover glass to provide a camera window for an electronic device are disclosed. A camera window can be integrated into the cover glass. The apparatus, systems and methods are especially suitable for cover glasses, or displays (e.g., LCD displays), assembled in small form factor electronic devices such as handheld electronic devices (e.g., mobile phones, media players, personal digital assistants, remote controls, etc.). The apparatus, systems and methods can also be used for cover glasses or displays for other relatively larger form factor electronic devices (e.g., portable computers, tablet computers, displays, monitors, televisions, etc.).
