Dual Under-Display Camera Layout With Variable Pixel Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large non-display areas in display panels are visually noticeable and limit the image display area, and the quality of images captured by camera modules positioned under the display is affected by pixel density and light incidence.
Innovation Solution
An electronic device with a display panel that includes overlapping display areas with varying pixel densities to accommodate camera modules, using at least two camera modules based on external illumination, and a processor to control image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pixels are arranged densely in the display area overlapping the camera module, then image quality captured by the camera module is improved, but the display area for image display is reduced
Solution Approach 1:
The patent applies local quality by creating different pixel densities in different regions of the display panel. Specifically, a first pixel density is used in a first region overlapping the camera module to improve image capture quality, while a second pixel density is used in a second region to maintain adequate display area. This spatial variation in pixel density resolves the contradiction between image quality and display area.
2Ease of manufacture
If the non-display area is made large to accommodate camera modules, then camera module placement is facilitated, but the display area is limited and the non-display area becomes visually noticeable
Solution Approach 1:
The patent resolves this contradiction by transitioning from a traditional layout with separate non-display areas to an integrated layout where pixels are arranged directly over the camera module location. This dimensional reorganization allows the camera module to be positioned within the active display area without creating visible non-display regions, thereby maintaining both adequate display area and proper camera module placement.
3Reliability
If pixels are removed from the display area to create a non-display area for the camera module, then camera module positioning is improved, but the image display area is reduced
Solution Approach 1:
Instead of removing pixels entirely to create a non-display area, the patent maintains pixels in the region overlapping the camera module but adjusts their density and arrangement. This local modification allows the camera module to be properly positioned while the pixels continue to function for display purposes, thereby preserving both camera module positioning and image display area.
