Tilted Camera Module in Display Panel for Square Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as OLED and LCD, face issues with capturing images of objects in front of them due to the camera module's position at the edge, leading to off-center or unnatural captures, as the target object is not squarely captured.
Innovation Solution
Incorporating a reflection pattern and a transflective reflection pattern on the display panel, with the camera module positioned between the substrates, allowing for improved light transmissivity and reflection, enabling the capture of images through transparent regions, thus ensuring the object is squarely captured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera module is disposed in the border of the display device, then the camera module can be integrated into the display device, but the camera module cannot squarely capture the target object that is disposed in front of the display device
Solution Approach 1:
The patent introduces a new spatial dimension by tilting the imaging sensor relative to the display surface. Instead of placing the camera module in the border plane, the sensor is angled so that its imaging surface intersects with the display surface, creating a geometric relationship where the optical axis passes through the center of the display while the physical module remains integrated in the border region.
2Device complexity
If the camera module is disposed in the border of the display device, then the display device structure is simplified, but the captured image shows the user looking at 'somewhere else' not at the camera
Solution Approach 1:
The patent employs asymmetric positioning and orientation of the imaging sensor. The sensor is tilted at a specific angle relative to the display surface, creating an asymmetric geometric configuration that allows the optical axis to align with the center of the display while the physical module remains offset in the border region. This asymmetric design resolves the conflict between structural simplicity and user gaze alignment.
3Measurement precision
If a reflection pattern and transflective reflection pattern are added to the display panel, then light transmissivity and reflection are improved for accurate image capture, but the device complexity increases
Solution Approach 1:
The transflective reflection pattern serves multiple functions simultaneously: it reflects ambient light to improve visibility of the display, transmits light from the imaging sensor to enable accurate image capture, and can be positioned to work with the tilted sensor configuration. This multi-functionality reduces the need for separate components and justifies the added structural complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for improved image definition and visibility by reflecting and transmitting light effectively, ensuring the camera module captures the object accurately, aligning with the user's gaze.
Implementation Method 1
a display device (e.g., the OLED device or the LCD device) capable of displaying an image and reflecting an image of an object that is disposed in front of the display device
Implementation Method 2
The transflective reflection pattern is disposed on the second substrate, and has an opening exposing at least a portion of at least one transparent region among the transparent regions included in a plurality of the pixel regions

AI summary
A display device includes a display panel and a camera module. The display panel displays an image on a first surface, and includes a first substrate, a sub-pixel structure, a reflection pattern, and a transflective reflection pattern. The first substrate included a plurality of pixel regions each having sub-pixel regions, a transparent region, and a reflection region surrounding the sub-pixel regions and the transparent region. The second substrate is disposed on the sub-pixel structure. The reflection pattern is disposed in the reflection region on the second substrate, and exposes the sub-pixel regions and the transparent region. The transflective reflection pattern is disposed on the second substrate, and has an opening exposing at least a portion of at least one transparent region among the transparent regions. The camera module is disposed in the second surface on the display panel, and the second surface is opposite to the first surface.
