In-Display Image Pickup Apparatus for Narrow Frame Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with front cameras face design constraints due to the camera's location in non-display regions, leading to space inefficiencies and user experience issues when taking selfies, as users tend to look downward instead of directly at the camera.
Innovation Solution
Integrating imaging components and image sensors within the display region of a display panel, utilizing microlenses and different types of imaging components to image targets at various object distances, allowing for image signal processing to achieve a depth of field, thus enhancing user experience and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the front camera is located in a non-display region of the display screen, then the camera can be integrated into the display device, but it takes up space in the peripheral region and is unfavorable for narrow frame design
Solution Approach 1:
The patent transitions the camera from a peripheral location (2D plane) to a location within the display region (utilizing the display pixels themselves), effectively using the third dimension of the display structure to accommodate the imaging function without increasing frame area
Solution Approach 2:
The display pixels serve dual functions: displaying images and capturing images. By making the display region itself capable of both emission and detection, the patent eliminates the need for separate camera modules in the periphery, thereby reducing frame width while maintaining camera functionality
2Ease of manufacture
If the front camera is located in a non-display region, then the camera can be integrated, but users tend to look downward instead of directly at the camera, worsening user experience
Solution Approach 1:
By enabling the display pixels to function as both display and capture elements, the camera can be positioned directly in the user's line of sight. This multi-functional approach allows the same region to serve dual purposes, improving selfie quality by enabling direct eye contact during self-photography
3Area of stationary object
If imaging components are integrated into the display region, then space utilization is improved, but the structure becomes more complex with multiple imaging components and image sensors
Solution Approach 1:
The patent combines the display function and image capture function into a single integrated structure. The display pixels serve dual purposes, and the imaging components are merged with the display region, reducing overall device complexity despite the advanced functionality achieved
4Adaptability or versatility
If multiple imaging components with different focal lengths are used, then imaging capability at various object distances is improved, but the device complexity increases
Solution Approach 1:
The imaging system is segmented into multiple imaging components, each with different focal lengths, allowing the system to handle different object distances. This segmentation enables versatile imaging capability while managing complexity through modular design
