Multi-Layout Display Resampler for Sensor Reception and Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of sensors and display panels in electronic devices often results in perceivable image artifacts due to opaque materials in the display panel blocking light from reaching the sensor, and varying pixel resolutions affecting perceived image quality.
Innovation Solution
Implementing a display panel with multiple regions of different pixel resolutions, including a high-resolution region, a middle-resolution transition region, and a low-resolution region, and using image processing circuitry with resamplers to apply resolution compensation factors to input image data, thereby reducing perceivable transitions and enhancing image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If opaque material is implemented in the display panel to enable switching devices, then the sensor's ability to sense light is improved, but perceived image quality deteriorates due to pixel resolution variations
Solution Approach 1:
The display panel is divided into multiple regions with different pixel resolutions: a first region with first pixel resolution, a second region with second pixel resolution, and a third region with third pixel resolution. This segmentation allows the sensor to be positioned in a region optimized for light sensing while maintaining high image quality in other regions through appropriate resolution transitions.
Solution Approach 2:
Different regions of the display panel are assigned different pixel resolutions based on their functional requirements. The region containing the sensor uses a pixel resolution that optimizes light transmission, while other regions use higher resolutions for superior image display quality, creating local optimization throughout the panel.
2Reliability
If pixel resolution is reduced in certain regions to improve sensor light reception, then sensor performance is improved, but image quality in those regions deteriorates
Solution Approach 1:
The pixel resolution parameter is varied across different regions of the display panel. By changing the resolution parameter from first pixel resolution to second pixel resolution to third pixel resolution across different regions, the system optimizes both sensor light reception and overall image quality through parameter optimization.
3Productivity
If multiple pixel layouts are implemented with different resolutions, then real estate utilization is optimized, but perceivable transitions between regions are created
Solution Approach 1:
The display panel implements dynamic resolution transitions across three distinct regions. By progressively changing pixel resolution from the first region through the second region to the third region, the system creates smooth, adaptive transitions that reduce perceivable artifacts while optimizing real estate utilization for both display and sensor functions.

AI summary
An electronic device may include a display panel implementing a first region having a first pixel layout and a second region having a second pixel layout, a sensor disposed behind the first region, and image processing circuitry communicatively coupled to the display panel. The image processing circuitry may process image data associated with the first region of the display panel using a first pixel layout resampler and process image data associated with the second region of the display panel using a second pixel layout resampler.
