Solution Overview
Problem
Existing display apparatuses lack efficient control over light source modules to provide improved image quality and flexibility in displaying multiple contents on a modular display screen with varying characteristics, such as luminance, color gamut, and gamma, while maintaining power efficiency and durability.
Innovation Solution
A display apparatus comprising a plurality of light source modules arrayed like tiles, each driven by a driver configured to receive image data and identification information, allowing selective activation and deactivation of modules based on image characteristics, with sub-drivers controlling module groups to optimize luminance, color, and gamma settings for improved image quality and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If all light source modules are driven to display content, then the display area is maximized, but power consumption increases and light source durability decreases
Solution Approach 1:
The display screen is segmented into multiple independent light source modules arranged in a matrix. Each module can be independently controlled by the driver circuit, allowing selective activation of only those modules required to display the current content, thereby reducing overall power consumption while maintaining the necessary display area.
Solution Approach 2:
The system dynamically adjusts which light source modules are active based on the content being displayed. The driver circuit receives display content information and dynamically activates only the relevant modules, optimizing the balance between display area utilization and power consumption in real-time.
2Area of stationary object
If all light source modules are driven, then the display area is maximized, but the life of light sources decreases
Solution Approach 1:
By segmenting the display into independent light source modules, the system can rotate or restactivate modules that have been in use for extended periods. This reduces cumulative operating hours for individual modules, thereby extending their operational life while maintaining full display area coverage.
Solution Approach 2:
The system implements periodic activation patterns where light source modules are cycled on and off based on content requirements. This periodic usage reduces continuous operation stress on individual modules, extending their operational lifespan while ensuring the display area remains fully functional.
3Use of energy by stationary object
If light source modules are selectively driven based on content characteristics, then power consumption is reduced, but control complexity increases
Solution Approach 1:
The driver circuit is designed with multi-functionality to handle both full-screen and selective module activation modes. It can interpret display content information and automatically determine which modules to activate, consolidating control logic into a single versatile component rather than requiring separate control circuits for each module.
Solution Approach 2:
The driver circuit autonomously processes display content information and self-determines the activation pattern of light source modules without requiring external control signals. This self-service capability reduces the need for complex external control systems while achieving selective module activation for power savings.
4Reliability
If modular light source modules are used, then durability and light emission efficiency are improved, but the ability to display multiple contents with varying characteristics is reduced
Solution Approach 1:
The modular architecture segments the display into independent light source modules that can be selectively activated. This segmentation enables different combinations of modules to be used for different content types, allowing the system to optimize display characteristics for various content while maintaining the durability benefits of individual modular units.
Solution Approach 2:
The system dynamically reconfigures which light source modules are active based on the characteristics of the content being displayed. This dynamic adaptability allows the same modular hardware to efficiently display multiple content types with varying requirements, combining the durability of modular design with the flexibility needed for diverse content display.
