Display Panel Transmission Lines for Narrow Frame Control Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel display apparatuses have a wide frame due to the separate and redundant control circuits for gate and data lines, which increases production costs and complicates the manufacturing process.
Innovation Solution
The integration of transmission lines extending in the same direction as gate lines and electrically connected to them, with a single control circuit connected to both data and transmission lines, reduces the number of control circuits and minimizes the frame width, allowing for an ultra-narrow or frame-free design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate control circuits are used for gate lines and data lines, then signal transmission control is achieved, but the frame width increases and device complexity increases
Solution Approach 1:
The patent merges the gate line control function and data line control function into a single control circuit. The transmission lines are electrically connected to both the gate lines and the control circuit, allowing the control circuit to simultaneously control both gate lines and data lines without requiring separate control circuits for each, thereby reducing the frame width while maintaining signal transmission control reliability
2Reliability
If separate control circuits are used for gate lines and data lines, then signal transmission control is achieved, but production cost increases and manufacturing process becomes complex
Solution Approach 1:
The patent combines multiple control circuits into a single control circuit that manages both gate lines and data lines through transmission lines. This integration reduces the number of control circuits from two separate circuits to one unified circuit, simplifying the device architecture and manufacturing process while maintaining the ability to control signal transmission to both gate and data lines
Solution Approach 2:
The single control circuit is designed with multi-functionality to perform both gate line control and data line control functions. By making the control circuit universal, it can simultaneously manage different types of lines (gate lines and data lines) through the transmission lines, reducing overall device complexity and the number of components required
3Device complexity
If transmission lines are added to extend in the same direction as gate lines, then control circuit integration is enabled, but the number of lines increases
Solution Approach 1:
The patent introduces transmission lines that extend in the same direction as the gate lines, creating a dimensional arrangement where control signals can be transmitted along the gate line direction to reach both gate lines and data lines. This dimensional change allows the control circuit to be integrated more efficiently by utilizing the existing gate line direction for transmission line placement, thereby managing the line arrangement area effectively
