Display Device Data Divider for Tiled LCD Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen LCD devices face size limitations and resolution decreases when attempting to increase panel size, and tiled LCD devices require complex driving circuits to control multiple panels.
Innovation Solution
A display device with a simplified driving circuit, comprising a plurality of display modules, module drivers, a data divider, and a timing control signal generator, which divides data signals and generates modulated control signals to be supplied to the module drivers, allowing for unified control of multiple LCD modules using a single image output system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large-sized LCD panel is used to achieve large-screen display, then the screen size is increased, but the manufacturing capability is limited and resolution decreases
Solution Approach 1:
The display device is divided into multiple small-sized LCD panels (first, second, third, and fourth LCD panels) arranged in a tiled configuration. Each panel is driven by its own dedicated image output system, allowing the system to achieve a large overall screen area while maintaining the manufacturing capabilities and resolution quality of individual smaller panels.
2Area of stationary object
If multiple image output systems are used to control multiple LCD panels in a tiled device, then the screen size is increased, but the device complexity increases
Solution Approach 1:
Multiple image output systems are merged into a single integrated image output system that can simultaneously control all LCD panels. The system includes a single data divider, timing control signal generator, and memory unit that coordinate to drive multiple panels, thereby reducing device complexity while maintaining large-screen capability.
3Area of stationary object
If multiple image output systems are used to control multiple LCD panels, then the screen size is increased, but the control difficulty increases
Solution Approach 1:
The image output system is designed with multi-functionality to simultaneously perform data division, timing signal generation, and control of multiple LCD panels through a unified interface. The single image output system can adaptively control different panels with potentially different resolutions, simplifying the operation and control architecture.
