Transparent Connection Layer for Camera Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels with camera devices have incomplete display areas due to small light-transmitting holes, which limits the screen-to-body ratio and display completeness.
Innovation Solution
A display panel design featuring a first display area with a liquid crystal layer and driving circuit layer, and a second display area with a transparent connection layer, allowing for increased light transmittance and pixel density distribution to enhance the screen-to-body ratio and complete the display area, while a camera device collects external light signals through the second display area for imaging.

Engineering Contradiction Analysis
1Area of stationary object
If light-transmitting holes are used for camera access, then screen-to-body ratio is improved, but display area completeness deteriorates
Solution Approach 1:
The display panel is divided into a first display area with full display function and a second display area with light-transmitting function for camera access. This segmentation allows different regions to serve different purposes, resolving the contradiction between maximizing screen-to-body ratio and maintaining display area completeness.
Solution Approach 2:
Different areas of the display panel are assigned different functional qualities: the first display area maintains full display capability with pixel electrodes and liquid crystal layers, while the second display area is optimized for light transmission with transparent connection layers and reduced pixel density, allowing the camera to capture external light signals.
2Illumination intensity
If transparent connection layer is used in second display area, then light transmittance is improved, but manufacturing complexity increases
Solution Approach 1:
The transparent connection layer serves multiple functions: it provides electrical connection between driving circuit units and liquid crystal layers, maintains structural integrity of the display panel, and enables light transmission for camera access in the second display area. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The transparent connection layer is integrated within the existing layered structure of the display panel, nesting the light-transmitting function within the connection layer rather than adding a separate component. This integration reduces manufacturing steps and overall device complexity.

AI summary
A display panel and an electronic device are provided. The display panel includes a first display area and a second display area. The first display area includes a first liquid crystal layer and a driving circuit layer. The driving circuit layer includes a first driving unit group and a second driving unit. The first driving unit group is configured to drive the first liquid crystal layer. The second display area includes the second liquid crystal layer and the transparent connection layer, and the second driving unit group drives the second liquid crystal layer through the transparent connection layer, so to complete the display area of the display panel.
