Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face insufficient charging times for pixel electrodes due to inadequate data signal transmission, particularly when data voltage is sent through adjacent pixel circuits, leading to inefficient image display operations.
Innovation Solution
The implementation of a display device design where first and second switches, located at non-adjacent rows of pixel electrodes, electrically connect the data line to the pixel electrodes, ensuring sufficient charging by extending the time span between gate signals, and the use of data transmission lines that connect pixel electrodes across rows, facilitating efficient data voltage delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data voltage is sent through adjacent pixel circuits, then the structure is simple, but the charging time is insufficient
Solution Approach 1:
The patent divides the data transmission path into separate segments by using non-adjacent row switches. Instead of transmitting data through adjacent pixel circuits which creates a continuous path, the invention segments the transmission by routing data through switches in non-adjacent rows (e.g., row 1 and row 3), thereby extending the transmission duration and preventing insufficient charging while maintaining structural simplicity.
2Device complexity
If switches are placed in adjacent rows, then the device complexity is reduced, but the charging efficiency decreases
Solution Approach 1:
The patent transitions from a one-dimensional adjacent row arrangement to a two-dimensional non-adjacent row arrangement. By distributing switches across non-adjacent rows in the vertical dimension, the invention extends the data transmission path length and duration, thereby improving charging efficiency without significantly increasing device complexity, as the switch count remains similar but their spatial distribution changes.
3Duration of action of moving object
If data transmission line connects non-adjacent pixel electrodes, then charging time is sufficient, but the transmission path becomes more complex
Solution Approach 1:
The patent makes the data transmission line multi-functional by enabling it to connect non-adjacent pixel electrodes through switches in different rows. The same transmission line structure serves multiple purposes: it provides extended charging time for sufficient voltage delivery while also enabling flexible routing to multiple pixel electrodes across different rows, thereby managing complexity through universal design rather than requiring separate dedicated paths for each function.
