Transparent Display Region for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of cameras and infrared face recognition structures in display devices reduces the screen-to-body ratio, hindering the realization of full screen display due to their placement in non-display regions.
Innovation Solution
A display panel design with a base substrate featuring a first display region with lower sub-pixel density and smaller sub-pixel area, allowing for increased transparent regions where imaging structures can be integrated without reducing the display area, and a second display region with higher sub-pixel density for normal display functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cameras and infrared face recognition structures are set in non-display regions, then imaging functions are achieved, but screen-to-body ratio decreases
Solution Approach 1:
The patent merges the imaging function with the display region by integrating cameras and infrared face recognition structures within the display area. The first display region is designed with transparent regions that allow these imaging components to be positioned inside the display region rather than in separate non-display regions, thus combining display and imaging functions in one space.
Solution Approach 2:
The patent utilizes the vertical dimension by positioning imaging structures at different depths within the display panel. The cameras and infrared face recognition structures are arranged in the first display region with transparent regions, allowing them to be integrated without occupying horizontal display space, effectively using the Z-axis dimension to resolve the space conflict.
2Area of stationary object
If imaging structures are integrated in display regions, then screen-to-body ratio increases, but display quality may be compromised
Solution Approach 1:
The patent applies local quality by creating a first display region with different characteristics from the second display region. The first display region contains transparent regions with lower sub-pixel density specifically where imaging structures are located, while the second display region maintains normal high-density sub-pixel arrangement for optimal display quality in areas without imaging components.
Solution Approach 2:
The patent segments the display panel into two distinct display regions: a first display region with transparent regions for imaging function integration and a second display region with normal sub-pixel density for high-quality display. This segmentation allows each region to be optimized for its specific function without compromising the other.

AI summary
Disclosed are a display panel and a display device. The display panel includes a base substrate, and a first display region and a second display region that are located on the base substrate, where the first display region includes a plurality of first sub-pixels and a plurality of transparent regions, the second display region includes a plurality of second sub-pixels, and a distribution density of the first sub-pixels is smaller that of the second sub-pixels; and an area occupied by the first sub-pixels is smaller than that occupied by the second sub-pixels.
