Array Substrate Gate Drive Circuit Scanning Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel technologies face interruptions in scanning due to issues with shift registers, leading to incomplete full-screen scanning, despite bilateral arrangements of gate integrated drive circuits, which cannot guarantee full-screen scanning.
Innovation Solution
An array substrate design with two groups of gate integrated drive circuits at both ends of gate lines, where each shift register's output terminal is connected to both the gate line and the input terminal of the next level shift register, with first and second leads providing an overlapping area for insulation and signal transfer, ensuring smooth scanning by laser fusing or cutting connections as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gate integrated drive circuits are bilaterally arranged at both ends of gate lines, then the problem of scanning interruption at single end is ameliorated, but full-screen scanning cannot be completely guaranteed due to potential failures at multiple levels
Solution Approach 1:
The gate drive function is segmented into multiple independent shift registers arranged in series, where each shift register can independently drive a portion of the gate lines. This segmentation allows the system to maintain scanning functionality even when individual shift registers fail, as other segments can continue operating.
Solution Approach 2:
A compensation shift register is introduced as an intermediary component between the normal shift registers. This compensation register acts as a backup that can take over the driving function when a normal shift register fails, ensuring continuous scanning operation and full-screen coverage.
2Stability of the object's composition
If shift registers are connected in series for gate line scanning, then scanning sequence is maintained, but scanning interruption occurs when a shift register fails to generate or transmit trigger signals correctly
Solution Approach 1:
The compensation shift register is pre-configured and positioned in advance within the series connection of shift registers. It stands by ready to receive and transmit trigger signals, so when a failure occurs in any normal shift register, the compensation register can immediately take over without disrupting the scanning sequence.
Solution Approach 2:
The system incorporates a backup compensation shift register that provides cushioning protection against potential failures in the normal shift registers. This redundant component ensures that even if trigger signal transmission fails at any point in the series connection, the scanning sequence can continue uninterrupted through the compensation register.
