Solution Overview
Problem
Current full-screen display products face challenges such as complex preparation processes, long average preparation times, and high production costs, which hinder the achievement of a true full-screen display with a high screen-to-body ratio.
Innovation Solution
A display panel design featuring a base substrate with a first and second display area, where the circuit structure layer includes pixel circuits and connecting lines that extend from the second display area to the first display area, allowing for the electrical connection and light emission of light emitting elements without overlapping with the anodes of the second light emitting elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connecting lines are routed to electrically connect pixel circuits to light emitting elements, then electrical connection is achieved, but the connecting lines may overlap with anodes of light emitting elements causing manufacturing complexity
Solution Approach 1:
The patent utilizes multiple layers (third conductive layer and fourth conductive layer) to route connecting lines in different spatial dimensions, allowing lines to bypass anode regions without overlapping. This multi-dimensional routing approach achieves reliable electrical connection while avoiding manufacturing complexity associated with single-layer routing conflicts.
Solution Approach 2:
The connecting lines are divided into multiple segments across different conductive layers. The first connecting line is in the third conductive layer and the second connecting line is in the fourth conductive layer, allowing independent routing optimization for each segment to avoid anode overlap while maintaining electrical connectivity.
2Adaptability or versatility
If more conductive layers are added to route connecting lines, then routing flexibility increases, but device structure becomes more complex
Solution Approach 1:
The fourth conductive layer serves multiple functions: it provides additional routing paths for connecting lines and also functions as part of the electrode structure for light emitting elements. This multi-functionality approach increases routing flexibility while minimizing the addition of purely structural layers that would increase device complexity.
3Adaptability or versatility
If camera is installed on display device to meet shooting needs, then functionality is improved, but screen-to-body ratio decreases
Solution Approach 1:
The camera functionality is integrated within the display panel structure by locating the camera in the second display area and using the same conductive layers and pixel circuits for both display and camera functions. This merging approach allows shooting functionality without requiring additional external components that would increase the overall device footprint and reduce screen-to-body ratio.
