Display Controller Sleep Mode Recovery via Tab-Registered Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when waking a device from sleep mode, as they need to switch screens to access the desired standby screen, which is not displayed by default, requiring additional operations to change from the default screen.
Innovation Solution
A display controlling device with a controller that operates in a sleep mode where the standby screen is not displayed, and upon depression of a tab-registered key, it recovers to display the corresponding tab screen, allowing users to quickly access their desired screen upon waking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the default standby screen is displayed immediately after recovery from sleep mode, then the device operates reliably with a standard recovery procedure, but the user must perform additional tab switching operations to access the desired standby screen
Solution Approach 1:
The system performs preliminary action by storing the user's desired standby screen selection before entering sleep mode. When the device wakes up, it directly displays the pre-selected standby screen without requiring the user to switch tabs, thus eliminating the time loss while maintaining reliable operation.
Solution Approach 2:
The system uses feedback by detecting which tab the user has selected before sleep mode activation. This feedback information is stored and used to automatically restore the same tab selection after wake-up, creating a closed-loop system that adapts to user preferences and eliminates redundant operations.
2Adaptability or versatility
If the standby screen corresponding to the operation state before sleep is displayed, then the device maintains operational context, but the displayed screen may not be the user's desired standby screen, requiring additional switching operations
Solution Approach 1:
The system monitors user interactions with tabs before sleep mode and uses this feedback to determine the user's preferred standby screen. This feedback mechanism allows the system to balance maintaining operational context with displaying the user's actually desired screen, reducing the need for additional switching operations.
3Adaptability or versatility
If multiple tabs are provided on the standby screen, then the device offers versatility in displaying different standby screens, but the user requires additional operations to switch between tabs to access the desired screen
Solution Approach 1:
The system performs preliminary action by pre-selecting and storing the user's desired tab among multiple available tabs before sleep mode activation. Upon wake-up, it directly displays the pre-selected tab content, maintaining the versatility of having multiple standby screens while reducing the operational complexity to zero tab switching actions.

AI summary
A controller of a display controlling device is configured to display, on a display, a standby screen including multiple tabs, one of which is selectable, and a tab screen corresponding to a selected tab, at least one of the multiple hard keys serving as a tab-registered key associated with one of the multiple tabs, operate the display controlling device in a sleep mode in which the standby screen is not displayed. In response to a particular sleep condition being satisfied, the controller changes an operation mode of the display controlling device to the sleep mode, and in response to depression of the tab-registered key when the display controlling device operate in the sleep mode, the controller recovers from the sleep mode by changing the sleep mode and displaying the standby screen including the tab screen corresponding to the tab associated with the depressed tab-registered key on the display.
