Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Double-sided display devices face issues with poor display synchronization due to asynchronous operation of two display panels, leading to inconsistent screen displays.
Innovation Solution
A display panel design featuring single-way conducting switches connected between gate lines of opposing sub-panels, allowing a gate scan signal to be sent to one sub-panel while maintaining a cutoff signal on the other, ensuring synchronized display by unidirectional signal transfer through these switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two display panels are bonded opposite to each other for double-sided display, then the display device can show content on both sides, but the driving process becomes complicated and display synchronization deteriorates
Solution Approach 1:
The patent combines the gate scan signal input for both display panels into a single input terminal. The single-way conducting switches enable one gate scan signal to simultaneously control both display panels, merging what would traditionally require two separate signal inputs into one unified input, thereby simplifying the driving process while maintaining double-sided display functionality
Solution Approach 2:
The single-way conducting switches act as intermediaries between the single gate scan signal input and the two display panels. These switches receive the gate scan signal and unidirectionally transmit it to both display panels, mediating the signal distribution in a way that simplifies the overall driving architecture while ensuring proper signal routing to each panel
2Ease of operation
If gate scan signals are independently input to both display panels, then each panel can be controlled separately, but display synchronization deteriorates and asynchronous display occurs
Solution Approach 1:
The patent merges the gate scan signal inputs of both display panels into a single shared input terminal. By using single-way conducting switches to distribute this single signal to both panels, the system ensures that both panels receive identical gate scan signals simultaneously, achieving perfect display synchronization while maintaining the ability to independently control each panel through the switch architecture
3Reliability
If single-way conducting switches are added to achieve synchronized display, then display synchronization is improved, but device structure becomes more complex
Solution Approach 1:
The single-way conducting switches serve as intermediary components that enable synchronized display by unidirectionally transmitting the gate scan signal from a single input terminal to both display panels. While these switches add circuit elements, they do so in a controlled manner that achieves the critical function of synchronization without proportionally increasing overall system complexity
Solution Approach 2:
The patent segments the signal transmission path by introducing single-way conducting switches at specific points in the circuit. This segmentation allows the gate scan signal to be properly distributed to both panels while maintaining clear signal flow control, achieving synchronization through strategic placement of switching elements rather than complex overall circuit redesign
