Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for multi-screen displays in automotive intelligence and other applications requires a more efficient and cost-effective method to control and drive multiple display screens with varying resolutions and configurations, as existing technologies face challenges in simplifying complexity, reducing data transmission interference, and improving speed and security.
Innovation Solution
A display system comprising one or more display screens, a plurality of source drivers, a timing controller, and a graphics processor, where the graphics processor determines each frame of image and transmits it to the timing controller, which splits the image into sub-images through a Peer-to-Peer (P2P) transmission mode and outputs them to source drivers in parallel, enabling parallel data signal provision during line scans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display screens are controlled using existing technologies, then the display system can support multi-screen functionality, but the system complexity increases and data transmission interference occurs
Solution Approach 1:
The patent segments the display system into independent functional modules: graphics processor for image generation, timing controller for signal synchronization, and multiple source drivers for parallel screen control. Each module operates independently with defined interfaces, reducing overall system complexity while maintaining multi-screen capability
Solution Approach 2:
The timing controller serves as an intermediary between the graphics processor and multiple source drivers. It receives image data from the graphics processor, generates synchronization signals, and distributes data to multiple source drivers in parallel, thereby simplifying the control architecture and reducing data transmission interference
2Reliability
If data is transmitted sequentially to multiple display screens, then transmission interference is reduced, but transmission speed decreases
Solution Approach 1:
The image data is segmented into separate data streams for each display screen, with each source driver receiving and processing data independently. This parallel segmentation enables simultaneous data transmission to multiple screens without interference, improving both speed and reliability
Solution Approach 2:
The patent transitions from sequential (one-dimensional) data transmission to parallel (multi-dimensional) transmission by establishing independent data pathways from the timing controller to multiple source drivers. This dimensional change enables simultaneous data delivery to multiple displays, dramatically increasing transmission speed while maintaining signal integrity through dedicated channels
3Device complexity
If a single controller manages all display screens, then system cost is reduced, but control precision and reliability decrease
Solution Approach 1:
The control function is segmented between the timing controller (central coordination) and individual source drivers (screen-specific control). This hierarchical segmentation maintains cost-effectiveness with minimal controllers while achieving high reliability through distributed control at the source driver level, where each driver independently manages its connected display screen
Solution Approach 2:
The timing controller acts as a mediator that provides synchronized control signals to multiple source drivers, ensuring coordinate management across all displays. Each source driver then independently translates these synchronized signals into screen-specific control actions, achieving both unified coordination and precise individual control for high reliability
