Under-Display Image Acquisition Through-Hole Electrode Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses face manufacturing difficulties and reduced effective display area due to the need for slots or grooves to accommodate camera devices, which limit the display effect and increase manufacturing complexity.
Innovation Solution
A display apparatus with an image acquisition region on the display panel, featuring light-emitting elements with non-transparent electrodes having through-holes to allow external light passage, enabling image capture without reducing the display area, and an image acquisition device positioned to capture outside patterns, allowing for both camera functionality and display functionality within the same area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a slot or groove is cut in the display panel to accommodate the camera device, then the camera can capture external images, but the manufacturing difficulty increases and the effective display area is reduced
Solution Approach 1:
The patent merges the camera function with the display panel by integrating the image acquisition device directly into the display structure. The camera device is positioned at the back of the display panel, sharing the same space, which eliminates the need for separate slots or grooves and simplifies manufacturing while maintaining full display area.
Solution Approach 2:
The patent transitions from a two-dimensional display surface to a three-dimensional integration by placing the camera device in the depth dimension behind the display panel. This allows the camera to be accommodated without occupying any display area or requiring modifications to the front surface of the display panel.
2Adaptability or versatility
If a slot or groove is cut in the display panel to accommodate the camera device, then the camera can capture external images, but the effective display area is reduced
Solution Approach 1:
The patent utilizes the third dimension (depth) by positioning the camera device behind the display panel. This spatial arrangement allows the camera to be integrated without reducing the two-dimensional display area, as the camera occupies space in the depth dimension rather than the display surface area.
Solution Approach 2:
The display panel and camera device are merged into a single integrated structure where the camera is housed within the display panel assembly. This integration allows both functions to coexist without the camera requiring separate space that would reduce the display area.
3Adaptability or versatility
If light-emitting elements with through-holes are used in the image acquisition region, then external light can pass through for image capture, but the display functionality in that region must be maintained
Solution Approach 1:
The patent applies local quality by creating through-holes only in the specific regions where light-emitting elements are located within the image acquisition region. This allows external light to pass through these localized areas for image capture while maintaining the normal display functionality in other regions, thus managing complexity by targeting modifications only where necessary.
Applied Scientific Principles
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 enhances the display area and display effect by allowing image acquisition without the need for slots or grooves, simplifying manufacturing and maintaining the display functionality, while ensuring the image acquisition device does not obstruct the display.
Implementation Method 1
the non-transparent electrode is provided with at least one through-hole therein, configured to allow the lights from the outside pattern to pass through the display panel
Implementation Method 2
The image acquisition device is at a position corresponding to the image acquisition region, and is configured to capture an image based on lights from an outside pattern
Implementation Method 3
each of at least one of the one or more first light-emitting elements can further include an organic light-emitting functional layer and a first electrode
