Through Hole Display Panel for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional electronic apparatuses, users cannot simultaneously look straight at a camera and view their image on the screen while taking a photo, making it difficult to capture ideal images.
Innovation Solution
An electronic apparatus with a display panel featuring a through hole in the display region, allowing an image capturing device to capture images through the hole, enabling users to look directly at the camera while viewing their image on the screen, utilizing a pinhole imaging principle or fiber camera array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate camera and screen are provided in conventional electronic apparatus, then the camera can capture images and the screen can display images, but the user cannot simultaneously look straight at the camera and view their image on the screen when taking a photo
Solution Approach 1:
The patent merges the camera and screen into a single integrated display panel structure. The camera is positioned behind the display panel and captures images through a through-hole in the pixel region, allowing the screen to display both the captured image and the user's real-time view simultaneously. This integration enables users to look straight at the camera while viewing their image on the screen, resolving the contradiction between ease of operation and visual information loss.
Solution Approach 2:
The patent utilizes the thickness dimension of the display panel by positioning the camera behind the panel and forming a through-hole in the pixel region. This three-dimensional arrangement allows light to pass through the display panel from the front, enabling the camera to capture images while the screen displays them simultaneously, thus solving the problem of users being unable to view both the camera and screen at the same time.
2Ease of operation
If the through hole is formed in the pixel region, then the user can look straight at the camera while viewing the screen, but the display area is reduced
Solution Approach 1:
The patent applies local quality by forming the through-hole specifically in one of the sub-pixel regions (red, green, or blue sub-pixel) rather than in the entire pixel region. This localized approach minimizes the impact on display area while still enabling the camera to capture images through the through-hole. The small size of the through-hole (smaller than the sub-pixel region) ensures that the reduction in display area is minimal while maintaining the functionality of selfie photographing.
3Area of stationary object
If the through hole is formed in the black matrix region, then the display area is better preserved, but the structural complexity increases
Solution Approach 1:
The patent provides two implementation options: forming the through-hole in the pixel region or in the black matrix region. When formed in the black matrix region, the through-hole structure is integrated into the existing black matrix pattern, which helps maintain display area while managing structural complexity through careful design of the hole's position and size within the black matrix framework.

Function Achieved in This Case
Enables users to take photos while looking directly at the camera and viewing the screen, resulting in a satisfying orthographic image.
Implementation Method 1
the image capturing device comprises a lens group disposed to face toward the through hole to capture an image through the through hole by using a pinhole imaging principle
Implementation Method 2
the image capturing device comprises a fiber camera, at least a part of which is disposed in the through hole
