Display Panel Layout With Embedded Lens Modules for Full-Screen Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with high screen-to-body ratios cannot achieve a true full-screen display due to the need for a 'forehead' or 'chin' to accommodate cameras, which reduces the display area.
Innovation Solution
A display panel design incorporating lens imaging modules with adjustable focal length, integrated between pixel units, allowing for camera functionality without affecting the display and increasing the screen-to-body ratio by eliminating the need for a traditional camera layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is located at the uppermost or bottommost position of the display screen, then the camera functionality is achieved, but the display area is reduced due to the presence of 'forehead' or 'chin'
Solution Approach 1:
The patent moves the camera from the traditional planar position at the top or bottom edge of the display screen to a position within the display panel itself, utilizing the third dimension (depth/thickness) of the panel. This allows the camera to be embedded between the front and back substrates, eliminating the need for 'forehead' or 'chin' regions and achieving a true full-screen display while maintaining camera functionality.
Solution Approach 2:
The camera module is nested within the display panel structure, specifically positioned between the front substrate and back substrate. The lens imaging module is integrated into the display panel's internal space, allowing the camera to be contained within the display device without occupying external display area, thus resolving the contradiction between camera functionality and display area.
2Reliability
If a traditional camera layout is used, then the camera functionality is achieved, but the screen-to-body ratio is reduced due to the presence of 'forehead' or 'chin'
Solution Approach 1:
The patent transitions from a two-dimensional camera layout (at the top or bottom edge) to a three-dimensional integration within the display panel. The lens imaging module is positioned in the internal volume of the display panel, utilizing the depth dimension to achieve camera functionality without reducing the screen-to-body ratio.
Solution Approach 2:
The camera module is nested within the display panel structure, embedded between the front and back substrates. This nesting approach allows the camera to be housed within the display device's internal space, eliminating the need for external camera protrusions or display area sacrifices, thereby maintaining a high screen-to-body ratio.

AI summary
A display panel includes: a first base substrate and a second base substrate which are opposite to each other, and a plurality of lens imaging modules. The first base substrate includes a plurality of pixel units arranged in an array. The plurality of lens imaging modules are located between the first base substrate and the second base substrate, and an orthogonal projection of the lens imaging module on the first base substrate is located between two adjacent pixel units. Therefore, the lens imaging modules are disposed inside the display panel without affecting display of the display panel, such that a screen-to-body ratio can be significantly increased, which is advantageous for achieving borderless full-screen display.
