Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple gate lines are driven using traditional multi-stage circuits, then each gate line can be driven independently, but the circuit size increases and bezel width increases
Solution Approach 1:
The patent merges the functionality of multiple stage circuits into a single stage circuit by implementing a gate driving circuit that can simultaneously drive multiple gate lines (GL1 to GL4) using one stage circuit (ST1), thereby reducing the overall circuit size and bezel width while maintaining independent gate line driving capability
Solution Approach 2:
The single stage circuit is designed with multi-functional capability to drive multiple gate lines simultaneously. The circuit incorporates multiple output nodes (OUT1 to OUT4) that can independently control different gate lines, making one stage circuit universal enough to replace multiple traditional stage circuits
2Reliability
If traditional gate driving circuits are used, then gate lines can be driven sequentially, but power consumption increases and resolution is reduced
Solution Approach 1:
The gate driving circuit enables simultaneous driving of multiple gate lines within one horizontal period through continuous operation. The circuit generates scan signals for multiple gate lines (GL1 to GL4) in parallel without sequential delays, maintaining continuous useful action and reducing overall power consumption compared to traditional sequential driving methods
3Reliability
If multiple stage circuits are used to drive gate lines, then comprehensive coverage is achieved, but manufacturing cost increases
Solution Approach 1:
The invention combines multiple stage circuits into a single integrated gate driving circuit that provides comprehensive gate line coverage. By merging the functions of multiple stages into one circuit block (ST1), the patent reduces the total number of circuit components required, thereby lowering manufacturing costs while maintaining full coverage of all gate lines (GL1 to GL4)
Solution Approach 2:
The single stage circuit is designed with universal functionality to cover all gate lines through multiple output nodes. This multi-functional design eliminates the need for multiple specialized stage circuits, simplifying the manufacturing process and reducing overall manufacturing cost while achieving comprehensive gate line驱动 coverage

AI summary
A gate driving circuit and a display apparatus including the same are disclosed, in which a plurality of gate lines may be driven through one stage circuit. The gate driving circuit includes first to mth stage circuits outputting a plurality of scan signals by dividing the scan signals into a first signal group and a second signal group. The first to mth stage circuits are grouped into k number of stage groups having two adjacent stage circuits, stage circuits of jth stage group (j is a natural number of 1 to k−1) output the scan signals of the first signal group to be earlier than the scan signals of the second signal group, and stage circuits of (j+1)th stage group output the scan signals of the second signal group to be earlier than the scan signals of the first signal group.
