Display Device Segmented Pixel Regions for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with integrated cameras face limitations in display area due to the need for a border region to accommodate the camera lens, resulting in reduced image display capability.
Innovation Solution
A display device design featuring a substrate with two distinct display regions, one for passive pixels and the other for active pixels, where the active pixels include an active element connected to a driving circuit and a light-emitting diode, and the passive pixels are directly connected to a driving circuit, allowing for increased transmittance and display area by optimizing the placement of optical modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a border region is created to accommodate the camera lens, then the camera function can be integrated, but the display area is reduced
Solution Approach 1:
The display panel is segmented into two distinct display regions: a first display region with passive pixels and a second display region with active pixels. This segmentation allows different pixel types to serve different functions, with the passive pixel region optimized for camera integration and the active pixel region for high-quality display, thereby resolving the contradiction between camera integration and display area.
Solution Approach 2:
Different regions of the display panel are assigned different pixel qualities and functions. The first display region uses passive pixels suitable for areas where camera integration is needed, while the second display region uses active pixels for areas requiring superior display performance. This local differentiation allows the system to achieve both camera integration and maximized display area without compromise.
2Adaptability or versatility
If the display panel is drilled to set the camera lens, then the camera module can be mounted, but the display function is lost in that portion
Solution Approach 1:
The display panel achieves multi-functionality by incorporating both passive and active pixel regions, allowing the same display structure to serve both camera integration and full-area display functions. The passive pixel region specifically enables camera module mounting while maintaining partial display capability, and the active pixel region provides high-quality display, together achieving universal functionality.
3Illumination intensity
If the entire display region uses active pixels, then display quality is maximized, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of uniformly applying active pixels across the entire display panel, the invention applies active pixels only to the second display region where high display quality is prioritized, while using simpler passive pixels in the first display region. This local quality differentiation optimizes the balance between display quality and manufacturing complexity.
Solution Approach 2:
The display panel is divided into segments with different pixel technologies. The first display region uses passive pixels with simpler structure and lower manufacturing complexity, while the second display region uses active pixels for enhanced display quality. This segmentation resolves the contradiction by allowing each region to be optimized independently.
