Under-Display Motion Blurring for Scintillation and Boundary Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scintillations occur in regions of lower pixel-density displays due to under-display sensors, causing visible boundaries and degrading user experience.
Innovation Solution
Implement motion-induced blurring techniques that adjust the amount of blurring based on the speed and resolution of moving content, applying it only when necessary to reduce scintillations and boundary appearance.

1Area of stationary object
If under-display sensors are placed in regions of the display, then the display size can be increased, but the pixel-density in those regions must be reduced which causes scintillations and visible boundaries
Solution Approach 1:
The patent applies different pixel-density characteristics to different regions of the display. Regions with under-display sensors have reduced pixel-density to accommodate the sensors, while other regions maintain higher pixel-density. This local differentiation allows the display to accommodate sensors without sacrificing overall display area, while managing the visual quality trade-off in specific zones.
Solution Approach 2:
The patent dynamically adjusts rendering parameters based on the detected motion state of content. When motion is detected in low pixel-density regions, the system changes rendering parameters by applying motion-induced blurring to reduce scintillations. This parameter change allows the display to maintain acceptable visual quality in regions with reduced pixel-density by adapting the display characteristics to the content being shown.
2Object-affected harmful factors
If motion-induced blurring is applied to reduce scintillations, then the appearance of boundaries is reduced, but the blurring amount must be adjusted based on content speed to avoid excessive blur
Solution Approach 1:
The patent employs motion detection to sense the speed and direction of content movement in real-time. This feedback information about content motion is then used to dynamically adjust the degree of motion-induced blurring applied to low pixel-density regions. The system responds to actual motion conditions, increasing blur when motion is detected and reducing or eliminating blur when content is stationary, thereby adapting to varying content characteristics.
Solution Approach 2:
The patent makes the blurring effect dynamic rather than static. The degree of blurring is continuously adjusted based on detected motion parameters, allowing the display to adapt its appearance in real-time. When content moves faster, more blurring is applied to reduce scintillations; when content is slower or stationary, less blurring is applied to preserve detail. This dynamic adjustment resolves the contradiction between reducing scintillations and maintaining visual quality.

AI summary
This document describes techniques and devices for motion-induced blurring to reduce an appearance of a boundary separating regions of a display. Sensors (e.g., cameras, microphones, biometric sensors, ambient light sensors, radar sensors, and so forth) may be placed at least partially underneath regions of a display. Placing a sensor underneath a region of a display, however, often requires reduced pixel-density (e.g., relatively low resolution), which can cause scintillations of the content as it moves on the display. The techniques described herein address some undesirable effects of this reduced pixel-density by blurring content moving within regions of low resolution. Furthermore, the techniques can adjust an amount of blurring based on a speed of the moving content. Thus, when the display includes regions of differing resolutions, the techniques described herein can blur the moving content to reduce the appearance of a boundary separating these regions of differing resolutions.
