Transparent Flexible Substrate Camera Assembly for High Screen Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels face a limitation in increasing screen ratio due to the presence of front-facing cameras, which occupy space and require larger black edges to avoid blocking light, making it difficult to integrate high-screen ratio or full-screen designs.
Innovation Solution
A display panel design featuring a transparent flexible base substrate with a camera assembly disposed on the side, allowing the camera to operate under the display area without the need for camera holes, achieved by using a stacked arrangement of a wire connecting substrate, image sensor, infrared filter, focus motor, and lens unit, with a protection lens and polarizer, enabling light transmittance and image capture without obstructing the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If front-facing cameras are disposed on conventional display panels, then image capture function is achieved, but screen ratio is reduced due to camera holes and black edges
Solution Approach 1:
The camera assembly is moved from the front surface (2D plane) to the back side of the display panel, utilizing the third dimension (depth/thickness) to resolve the conflict between camera functionality and screen ratio. The camera assembly is disposed on a side of the display area adjacent to the flexible base substrate, allowing light to pass through the transparent display panel to reach the camera sensor without occupying front display area.
Solution Approach 2:
The flexible base substrate is made transparent, changing its optical property from opaque to transparent. This allows the camera assembly to be positioned behind the display panel while still receiving light for image capture, effectively hiding the camera components from the front view and eliminating the need for camera holes.
2Adaptability or versatility
If cameras and display panels are alternately disposed, then camera function is maintained, but display area is reduced due to occupied space
Solution Approach 1:
The camera assembly is positioned in the depth dimension behind the transparent display panel rather than occupying lateral space that would reduce display area. The stacked arrangement places the camera assembly on a side of the display area adjacent to the flexible base substrate, maximizing the front display area while maintaining camera functionality.
3Adaptability or versatility
If camera holes are created on display panels, then camera light path is enabled, but display integrity is compromised
Solution Approach 1:
Instead of creating holes in the display panel (compromising display integrity), the camera assembly is positioned in the third dimension behind the transparent panel. Light travels through the transparent flexible base substrate to reach the camera sensor, maintaining the continuous integrity of the display panel structure.
Solution Approach 2:
The transparent flexible base substrate allows light to pass through without interruption, enabling the camera to receive light through the panel material itself rather than through holes. This maintains the structural integrity and visual continuity of the display panel.

Function Achieved in This Case
This configuration enhances light transmittance and allows for seamless image shooting while maintaining normal display functionality, effectively increasing the screen ratio by eliminating the need for camera holes and larger black edges.
Implementation Method 1
the flexible base substrate is a transparent flexible base substrate... allowing light transmittance and image capture without obstructing the display
Implementation Method 2
the display panel further comprises a polarizer, wherein the polarizer is disposed on a side of the touch layer away from the flexible base substrate
Implementation Method 3
an infrared filter... sequentially disposed in a stacked arrangement

AI summary
A display panel and a display device are disclosed. The display panel includes a first substrate and a camera assembly. The first substrate includes a display area and a non-display area. The display area includes a flexible base substrate, a pixel array layer, a light-emitting layer, and a touch layer all sequentially disposed in a stacked arrangement. The camera assembly is disposed on a side of the display area adjacent to the flexible base substrate, so that an opening of the camera assembly of the display panel can be omitted, and a screen ratio of the display panel and the display device can be increased.
