Multi-Module Display Frame Rate Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses struggle to maintain and output the frame rate of each content when multiple contents with different frame rates are displayed simultaneously, leading to improper expression of motion in content with varying frame rates.
Innovation Solution
A display apparatus comprising multiple display modules, each with a corresponding timing controller (T-CON), and a processor that identifies the frame rate of each content and controls the T-CONs to operate the display modules at the respective identified frame rates, ensuring each content is displayed at its intended frame rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display apparatus outputs multiple contents at a common frame rate, then the display apparatus can simplify frame rate management and ensure consistent display performance, but the motion of objects in contents with different original frame rates cannot be properly expressed
Solution Approach 1:
The display apparatus divides the display into multiple regions, with each region corresponding to a different content source. Each region is controlled by its own timing controller that independently manages the frame rate for that specific content, allowing different frame rates to be maintained simultaneously without affecting other contents.
Solution Approach 2:
Different regions of the display are assigned different frame rates according to the requirements of each content source. This allows each content to be displayed at its optimal frame rate (e.g., 120 Hz for gaming content, 60 Hz for video content) while other regions display their respective contents at their own frame rates, maintaining local optimization for motion expression.
2Reliability
If the display apparatus maintains different frame rates for multiple contents, then the motion integrity of each content is preserved, but the display apparatus must manage multiple timing controllers and frame rates simultaneously
Solution Approach 1:
The display apparatus is divided into multiple independent regions, each with its own timing controller. This segmentation allows each region to independently manage its frame rate without interfering with other regions, simplifying the overall system architecture while enabling different frame rates for different contents.
Solution Approach 2:
Each timing controller in the display apparatus is designed to handle multiple functions: it manages frame rate generation, synchronizes display operations, and coordinates with the content source. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while maintaining motion integrity.
3Device complexity
If the display apparatus uses a single timing controller for all display modules, then the device structure is simplified, but the frame rate of each content cannot be maintained independently
Solution Approach 1:
The display apparatus is divided into multiple independent regions, each with its own timing controller. This segmentation allows each region to independently manage its frame rate without interfering with other regions, simplifying the overall system architecture while enabling different frame rates for different contents.
Solution Approach 2:
The timing controllers are configured with different frame rate parameters according to the requirements of each content source. Each timing controller can operate at different frame rates (e.g., 120 Hz, 60 Hz) depending on the content being displayed, allowing independent frame rate maintenance while keeping the overall structure manageable.
