Integrated Driver for Dual Flat Panel Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual type flat panel display devices face issues with increased size and manufacturing cost due to unnecessary wiring and the need for separate gate and data drivers for each panel, leading to dead space and inefficiencies.
Innovation Solution
Designing a dual type flat panel display device where the gate and/or data signal source is integrated into a single chip, reducing the number of wirings and drivers, and using on/off switching devices to selectively drive each panel without increasing the number of wirings, thereby simplifying the configuration and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate gate and data drivers are used for each panel, then each panel can be driven independently, but the device size and wiring complexity increase
Solution Approach 1:
The patent combines the gate drivers and data drivers into a single integrated driver unit that can selectively drive either the first panel or the second panel. This merging eliminates the need for separate driver circuits for each panel, reducing the overall device area while maintaining independent panel driving capability through selective activation.
Solution Approach 2:
The integrated driver unit is designed to perform multiple functions: it can drive the first panel, drive the second panel, or remain inactive. This multi-functional design allows a single driver unit to replace what would traditionally require separate dedicated drivers for each panel, reducing wiring complexity and device size.
2Ease of operation
If separate gate and data drivers are used for each panel, then each panel can be driven independently, but the wiring complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the gate driver circuits and data driver circuits into a single integrated driver unit. This consolidation reduces the number of separate wiring connections needed, as the integrated unit internally manages the signal distribution to either panel, thereby simplifying the overall wiring architecture and reducing manufacturing complexity.
3Adaptability or versatility
If unnecessary wirings are included for both panels, then the device can support dual panel operation, but dead space and manufacturing cost increase
Solution Approach 1:
The patent extracts and eliminates unnecessary wiring from the device architecture. By designing an integrated driver unit that selectively activates wiring paths based on which panel needs to be driven, the patent removes the need for permanent dual-path wiring connections, thereby reducing dead space while maintaining dual panel operation capability when needed.
4Ease of operation
If separate gate and data drivers are used for each panel, then each panel can be driven independently, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple driver functions into a single integrated driver unit, which reduces the total number of components that need to be manufactured and assembled. This consolidation lowers manufacturing costs by reducing component count, simplifying the assembly process, and potentially enabling more efficient production of the integrated driver circuit.
