Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display devices face challenges in achieving high resolution and fast pixel charging times, particularly in 3D displays, due to the limitations of dual-gate and triple-gate technologies which compromise on cost and performance.
Innovation Solution
A display panel design with a specific arrangement of data lines and scan lines, where three rows of scan lines are disposed between every two rows of sub-pixels, and one column of data line is placed for every one or two columns of sub-pixels, increasing the number of gate driver units by 1.5 times while reducing the number of data lines to ⅔, thereby enhancing pixel charging time and reducing power consumption.

Engineering Contradiction Analysis
1Ease of manufacture
If dual-gate or triple-gate technology is adopted to reduce costs, then manufacturing cost is reduced, but pixel charging time decreases significantly
Solution Approach 1:
The gate driver is segmented into multiple independent gate driver units, each capable of driving a specific group of scan lines. This segmentation allows for optimized charging paths where each unit can independently charge pixels without interference from other units, thereby maintaining fast charging performance while using a cost-effective multi-gate architecture.
Solution Approach 2:
The patent introduces a time-dimensional optimization by carefully sequencing the operation of different gate driver units. By controlling the timing and order in which each gate driver unit operates on its assigned scan lines, the system achieves efficient pixel charging across the entire display panel, effectively resolving the charging time issue while maintaining cost benefits.
2Ease of manufacture
If triple-gate technology is used to reduce costs, then manufacturing cost is reduced, but charging time of pixels decreases
Solution Approach 1:
The system dynamically allocates and controls multiple gate driver units to operate on different scan line groups simultaneously. This dynamic operation allows the triple-gate architecture to achieve efficient pixel charging by optimizing the temporal and spatial distribution of charging operations, thereby maintaining fast charging performance while benefiting from reduced manufacturing costs.
Solution Approach 2:
By having multiple gate driver units operate continuously and simultaneously on different portions of the display panel, the system ensures that pixel charging occurs without interruption or delay. Each gate driver unit continuously charges its assigned pixels, maintaining high charging efficiency throughout the entire display area while using the cost-effective triple-gate structure.
3Ease of manufacture
If more gate lines are increased to 2 or 3 times for dual-gate or triple-gate technology, then cost is reduced, but pixel charging time is significantly reduced
Solution Approach 1:
The gate driver is divided into multiple independent gate driver units, each responsible for a specific subset of scan lines. This segmentation creates parallel charging paths that operate independently, allowing pixels across different regions of the display to be charged simultaneously, thereby maintaining high charging speed while using the cost-reduced multi-gate architecture.
Solution Approach 2:
Each gate driver unit is designed with multi-functionality to handle its assigned group of scan lines efficiently. By making each unit self-sufficient and capable of independent operation, the system achieves fast pixel charging across the entire panel without requiring a single complex high-speed driver, thus reducing overall cost while maintaining performance.
