Time Controller for Multi-Resolution Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex circuitry and control methods are required in electronic products with multiple display panels, as each panel needs a corresponding time controller and driving circuit, leading to increased complexity.
Innovation Solution
A display apparatus with multiple panels and a time controller that sends priority control signals to select the appropriate panel or combination of panels based on image data resolution, simplifying the circuit and control method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display panels are used to satisfy display needs, then display versatility and image quality are improved, but circuit complexity and control complexity increase
Solution Approach 1:
A single time controller is designed to control multiple display panels with different resolutions (e.g., 800×600, 640×480, 480×270). The controller can dynamically select which panel to activate based on the input signal resolution, making one controller perform the function of what would traditionally require multiple dedicated controllers, thus reducing circuit complexity while maintaining display versatility
Solution Approach 2:
Multiple display panels are merged under a single control system. Instead of having separate control circuits for each panel, the invention combines them into one unified control architecture where panels are selected through signal processing and control logic within the single time controller, reducing the overall circuit complexity
2Reliability
If each display panel has a corresponding time controller and driving circuit, then display reliability is improved, but device complexity increases
Solution Approach 1:
The single time controller is designed with multi-functional capabilities to handle different panel types and resolutions. It includes resolution detection functionality and control logic that can adapt to various panel configurations, ensuring reliable operation across different display scenarios without requiring multiple specialized controllers
Solution Approach 2:
The controller implements dynamic panel selection based on the input signal characteristics. The system can dynamically determine which panel to activate (main panel, subordinate panel, or combination) based on the resolution of the incoming video signal, providing adaptive control that maintains reliability while simplifying the overall control architecture

AI summary
A display apparatus comprises a plurality of display panels and a time controller electrically coupled to each of the display panels respectively. The time controller is configured for sending out at least two priority control signals to each of the display panels according to an image data, to select at least one of the display panels to displaying the image data.
