Display device and driving device for display device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as LCD and light emitting displays, face challenges with increasing size, space constraints, and risk of damage due to external impacts, as well as the need for always-on-display functionality that requires additional mounting space and increased exposure of the display panel.
Innovation Solution
A display device with a module housing that includes a first and second moving plate, driven by belts and motors, allowing the display panel to be pulled up or down for reduced exposure and efficient space use, enabling switching between always-on-display and normal modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device size is increased to meet user needs for larger screen, then the display area is improved, but the risk of damage due to external impact increases and more mounting space is required
Solution Approach 1:
The display panel is designed to be movable between extended and retracted positions within the housing. The driving assembly enables the display panel to dynamically adjust its position, allowing it to be pulled up for protection or extended for use, thus resolving the contradiction between display area and damage risk
Solution Approach 2:
The display panel is nested within the housing when not in use, with the housing accommodating the display panel in a retracted state. This nesting arrangement protects the display panel from external impacts while maintaining the capability to extend the display area when needed
2Adaptability or versatility
If the display panel is externally exposed for normal display mode, then the display functionality is improved, but the risk of damage due to external impact increases
Solution Approach 1:
The system provides dynamic positioning capability where the display panel can be extended for normal display functionality or retracted for protection. The driving assembly enables smooth transitions between these states, allowing the display to adapt between functionality and protection as needed
Solution Approach 2:
The housing serves multiple functions: it acts as both a protective enclosure and a mounting structure that accommodates the movable display panel. This multi-functionality allows the same structure to provide both protection and display capability without requiring separate systems
3Adaptability or versatility
If additional mounting space is allocated for always-on-display mode, then the display versatility is improved, but the space efficiency deteriorates
Solution Approach 1:
The display panel dynamically adjusts its position and exposure level to accommodate different display modes. For always-on-display, the panel can be partially extended, while for normal mode it extends fully. This dynamic adjustment eliminates the need for separate mounting spaces for different modes
Solution Approach 2:
The always-on-display functionality is merged with the normal display mode within the same housing and mounting structure. The single mounting space accommodates both modes by allowing the display panel to be positioned at different extension levels, combining multiple functions into one integrated system
4Area of moving object
If the display panel is fully extended for normal mode, then the display area utilization is improved, but the vulnerability to external impact increases
Solution Approach 1:
The display panel transitions from a static to a dynamic configuration, capable of being fully extended for maximum display area utilization or retracted to a protected position within the housing. This dynamic capability allows the system to optimize between display area and reliability based on operational needs
