Foldable Wallpaper Display With Offset-Based State Transitions

The patent applies dynamics by making the wallpaper display adaptive to different device states. The system dynamically adjusts the wallpaper display configuration based on whether the device is folded or unfolded, using state detection to trigger appropriate display modes. This resolves the contradiction by allowing the display area to be maximized in unfolded state while maintaining visual consistency in folded state through state-dependent rendering.

The patent changes display parameters (such as offset values, scaling factors, and clipping regions) based on device state. By storing multiple wallpaper configurations with different parameters for folded and unfolded states, and switching between them based on detected device state, the system maintains visual consistency while adapting to different screen areas.

The patent applies preliminary action by pre-calculating and storing offset values and display parameters for both folded and unfolded states. Before the actual state transition occurs, the system has already prepared the appropriate wallpaper configuration, allowing for smooth transitions without sudden picture changes. The offset information is computed in advance based on the geometric relationship between folded and unfolded screen areas.

The patent introduces an intermediary mechanism (the offset calculation and state detection system) that mediates between the unfolded and folded display states. This intermediary layer processes the transition smoothly by applying calculated offsets and transformations, preventing abrupt visual changes and maintaining user experience quality during state transitions.

The patent applies self-service by having the system automatically detect its own device state and self-adjust the wallpaper display parameters accordingly. The state detection mechanism monitors whether the device is folded or unfolded, and based on this self-detected information, the system automatically selects and applies the appropriate wallpaper configuration without requiring manual intervention or complex external control.

The patent implements feedback by using state detection to provide information about the current device configuration back to the display system. This feedback loop allows the system to continuously monitor the device state (folded or unfolded) and automatically adjust the wallpaper display parameters in response, creating a closed-loop control system that simplifies the overall complexity through automated adaptation.
