Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic paper display panels require a large number of driving chips and flexible circuit boards to charge data signal lines, leading to high costs, especially for longer displays like signs and billboards.
Innovation Solution
An array substrate with multiple display areas and a peripheral circuit area, featuring data signal lines, signal leads, and switch modules, where each data signal line is connected to a signal lead through a switch module, and all control terminals of switch modules in a display area are connected to a single control signal line, allowing for efficient charging and control of data signal lines across areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional electronic paper display panel uses multiple driving chips and flexible circuit boards to charge data signal lines, then the display can be driven, but the cost increases significantly
Solution Approach 1:
The patent merges multiple driving functions into a single driving chip by integrating multiple switch modules on one array substrate. Instead of using multiple separate driving chips and flexible circuit boards, the invention combines all switching control for multiple display areas into one unified driving chip, thereby reducing component count and overall system complexity while maintaining full driving capability
Solution Approach 2:
The driving chip is designed with multi-functionality to control multiple display areas through a single device. The switch modules within the driving chip can selectively connect different data signal lines to different display areas, allowing one driving chip to perform the work of multiple traditional driving chips, thus reducing the number of components needed
2Area of stationary object
If multiple driving chips are used to charge data signal lines in long electronic paper displays, then the display areas can be driven, but the overall cost becomes high
Solution Approach 1:
The patent merges the driving functions for multiple display areas into a single driving chip. The array substrate integrates multiple switch modules that can selectively route data signals to different display areas, eliminating the need for multiple separate driving chips and flexible circuit boards, thereby reducing component count and overall system complexity
Solution Approach 2:
The switch modules provide dynamic routing capability, allowing the single driving chip to adaptively connect different data signal lines to different display areas based on operational requirements. This dynamic switching mechanism enables one driving chip to serve multiple display areas that would traditionally require multiple dedicated driving chips
3Ease of operation
If each data signal line is connected to signal leads through individual switch modules, then precise control is achieved, but the number of control connections increases
Solution Approach 1:
Each switch module is designed with multi-functionality to handle multiple control tasks. The switch modules can selectively connect different data signal lines to different display areas, and can be controlled in groups or individually as needed. This universal design allows precise control of individual data signal lines while the modules themselves can operate in coordinated fashion to reduce the effective number of control connections required
