Dynamic PIP Display Area and Backlight Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with picture-in-picture (PIP) mode fail to dynamically adjust sub-screen areas and backlight settings based on the instant state of signal sources, leading to inefficient use of screen space and missed notifications, as they cannot differentiate display settings for multiple signal sources and do not provide timely updates when a signal source transitions from idle to active.
Innovation Solution
A display device with a processor that dynamically adjusts the size and position of display areas and corresponding backlight brightness based on the state of continuous image signals, allowing for separate display settings and dimming modes for each sub-screen area, ensuring timely notification and efficient use of screen space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PIP mode is enabled to display multiple signal sources simultaneously, then the user can view multiple pictures on one display monitor, but the sub-screen area for idle signal sources continues to occupy screen space and display idling screens, reducing viewing efficiency and causing information loss
Solution Approach 1:
The patent applies dynamics by making the sub-screen area dynamically adjustable rather than static. When a signal source transitions from idle to active state, the sub-screen area automatically expands to display the new content. This dynamic adjustment ensures that screen space is efficiently utilized while maintaining the ability to display multiple signal sources simultaneously, resolving the contradiction between display versatility and viewing efficiency.
2Ease of operation
If unified display settings are applied to all PIP sub-screen areas, then the display configuration is simple to manage, but different display settings cannot be appropriately applied to different PIP sub-screen areas based on their specific applications or images
Solution Approach 1:
The patent applies segmentation by dividing the display settings into independent controllable units for each PIP sub-screen area. Each sub-screen can have its own display settings (such as resolution, color mode, refresh rate) independently configured based on the specific requirements of the signal source it displays. This segmentation allows different parts of the display system to be optimized independently, resolving the contradiction between ease of operation and display setting flexibility.
3Productivity
If the user manually closes the sub-screen of an idle signal source or disables PIP mode, then screen space is freed up, but the user cannot receive instant state changes or new information when the signal source wakes from idle state
Solution Approach 1:
The patent applies feedback by implementing a state monitoring mechanism that continuously tracks the status of signal sources. When a signal source transitions from idle to active state, the system receives feedback about this state change and automatically responds by adjusting the sub-screen area to display the new content. This feedback loop ensures that screen space is efficiently utilized while preventing information loss, as the system proactively responds to signal source state changes without requiring manual user intervention.
