Display Control Unit Application Setting Pre-Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maintaining optimal display settings when switching between different application programs, leading to temporary drops in display quality due to the need for analysis and adjustment of display settings.
Innovation Solution
A control method for a display device involving a first and second control unit, where the first control unit manages display settings and the second control unit executes application programs, allowing for swift adjustment of display settings based on the application program's state, ensuring optimal display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display settings are adjusted by analyzing input video to match application program state, then display quality becomes suitable for the video, but there is a temporary drop in display quality during the adjustment period
Solution Approach 1:
The system pre-prepares multiple display setting data corresponding to different application programs in advance. When an application program is executed, the corresponding display setting data is immediately selected and applied without requiring real-time analysis or adjustment, thereby eliminating the temporary drop in display quality during the transition period.
2Extent of automation
If the device integrates both genre identification function and video display function, then the system can automatically adjust settings, but the device complexity increases
Solution Approach 1:
The system divides the control functions into two separate control units: a first control unit dedicated to video display and a second control unit dedicated to executing application programs. The first control unit holds multiple display setting data and selects the appropriate one based on notifications from the second control unit, achieving automatic adjustment while maintaining clear functional separation and reduced overall complexity.
3Adaptability or versatility
If display settings are changed in response to application program execution, then display quality matches the application state, but the system requires complex coordination between control units
Solution Approach 1:
The system uses a notification mechanism as an intermediary between the second control unit (application execution) and the first control unit (display control). The second control unit notifies the first control unit when an application program is executed, and the first control unit autonomously selects and applies the corresponding display setting data, thereby achieving adaptable display settings with minimal coordination complexity.

AI summary
A control method for a display device including a display unit, a first control unit, and a second control unit, the control method comprising: holding a plurality of display setting data relating to a display state of an image by the display unit in such a way that the plurality of display setting data are available for use by the first control unit, causing the first control unit to execute display control to cause the display unit to display an image based on display data, causing the second control unit to execute an application program and output the display data, and causing the first control unit to set an one of the plurality of display setting data corresponding to the application program in response to the second control unit starting up the application program.
