Display Panel Embedding Functional Components via Through Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In devices like mobile phones and tablets, functional components such as buttons, speakers, and cameras occupy valuable space, reducing the screen area due to limited disposal space, which affects user experience.
Innovation Solution
A display panel design featuring a first substrate and a second substrate with a pixel array and an electrode, where a through hole exposes part of the electrode, allowing functional components like speakers, cameras, or buttons to be embedded and electrically connected, while a passivation layer and glue frames provide sealing and space optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If functional components (buttons, speakers, cameras) are disposed separately from the display panel, then each component can be independently manufactured and assembled, but the disposing space is occupied and screen portion is reduced
Solution Approach 1:
The patent merges functional components (speaker, camera, button) with the display panel by embedding them within the display panel structure. The functional components are positioned in the same plane as the display panel, with their input/output surfaces aligned with the panel surface, creating an integrated device that saves disposing space and increases screen portion.
Solution Approach 2:
The patent transitions from traditional three-dimensional stacking (display panel above or below functional components) to a two-dimensional planar integration where functional components are embedded within the display panel plane. This dimensional change allows components to share the same space without increasing overall device thickness.
2Area of stationary object
If functional components are embedded within the display panel, then disposing space is saved and screen portion is increased, but the manufacturing process becomes more complex
Solution Approach 1:
The patent segments the display panel structure into distinct functional zones: a display region for the display panel and a non-display region for embedding functional components. This segmentation allows different manufacturing processes to be applied to different regions independently, simplifying the overall manufacturing complexity while achieving integration.
Solution Approach 2:
The patent introduces a non-display region as an intermediary space between the display region and the functional components. This intermediary region serves as a dedicated embedding zone that facilitates the integration of functional components without interfering with the display manufacturing process, thereby easing manufacturing complexity.
3Ease of operation
If functional components are disposed separately, then manufacturing and assembly is simpler, but valuable space is occupied reducing user experience
Solution Approach 1:
The patent merges functional components (buttons, speakers, cameras) with the display panel by embedding them within the display panel structure. The functional components are positioned in the same plane as the display panel, with their input/output surfaces aligned with the panel surface, creating an integrated device that saves disposing space and increases screen portion.
