Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display panels face issues with insufficient charging of pixel circuits due to short charging times, which affects the display effect.
Innovation Solution
The display panel design includes multiple pixel circuit rows and columns arranged in an array, with each row containing a first and second pixel circuit connected to separate scan and data lines. This configuration allows for independent control of charging times for each pixel circuit, enabling longer charging durations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If time-share multiplexing is used to control multiple pixel circuits through a single scan line, then device complexity is reduced, but pixel circuit charging time becomes insufficient
Solution Approach 1:
The scan lines are segmented into multiple independent scan lines (first scan line, second scan line, etc.), each dedicated to controlling specific pixel circuits. This segmentation eliminates the time-share multiplexing approach, allowing each pixel circuit to receive data signals simultaneously without waiting for time-division multiplexing cycles, thereby sufficient charging time while maintaining manageable device complexity through systematic organization.
2Device complexity
If time-share multiplexing is used to write data signals to pixel circuits, then the number of data lines is reduced, but display effect deteriorates due to insufficient charging
Solution Approach 1:
The data transmission path is segmented into multiple independent data lines (first data line, second data line, etc.), each dedicated to writing data signals to specific pixel circuits. This eliminates the time-share multiplexing approach, allowing simultaneous data writing to all pixel circuits, ensuring sufficient charging time and maintaining excellent display effect while managing device complexity through systematic line organization.
3Productivity
If scanning time is extended to accommodate multiple pixel circuit rows, then charging time for each pixel circuit is reduced, but if scanning time is shortened, then charging time becomes insufficient
Solution Approach 1:
The pixel circuit array is segmented into multiple independent rows, each controlled by its own dedicated scan line. This allows parallel scanning operations across different rows simultaneously, maintaining high productivity and fast scanning speed while ensuring each pixel circuit receives sufficient charging time through dedicated time slots on its specific scan line, eliminating the time-division multiplexing constraint.
