Under-display Camera Light Distortion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing devices face challenges in designing displays that accommodate cameras without compromising the display area, often resulting in notches or cutouts that disrupt the seamless operation of emissive displays.
Innovation Solution
The implementation of a display with distinct regions, each having different light-blocking structures that distort light in unique ways, paired with specific sensors under these regions, allows for image fusion using machine learning models to generate high-quality images while eliminating the need for notches or cutouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is positioned on the display surface, then the camera can be integrated into the device, but the display area is reduced due to notches or cutouts
Solution Approach 1:
The camera is nested under the display surface, with the sensor positioned beneath the display layers. Light passes through transparent regions of the display to reach the camera sensor, allowing the camera to be integrated into the device without creating notches or cutouts that would reduce the display area.
Solution Approach 2:
The camera system transitions from a two-dimensional surface mounting approach to a three-dimensional layered integration. The sensor is positioned in a layer beneath the display, and light travels through the display layers to reach the sensor, effectively utilizing the vertical dimension to resolve the conflict between camera integration and display area.
2Manufacturing precision
If light-blocking elements are added to the display, then light distortion can be controlled, but the display structure becomes more complex
Solution Approach 1:
Light-blocking elements are strategically positioned in specific regions of the display where needed to control light distortion. The display structure maintains simple, uniform regions in areas where light distortion control is not required, thereby managing overall structural complexity while achieving precise light control where necessary.
