Solution Overview

Problem

Current methods for restoring display on electronic devices require cumbersome operations, such as multiple taps on the screen, which can be frustrating for users who are unaware that tapping is the method for restoration, especially when transitioning from a low-luminance or black-out state to a steady state.

Innovation Solution

An image display control apparatus and method that utilizes a detector to sense an object's proximity to the display, allowing for automatic restoration to a steady state when the object is detected, eliminating the need for explicit tapping and simplifying the operation by integrating a display controller that changes states based on user presence and registered gestures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If display is restored by tapping operation on display panel, then display can be restored from low-luminance state, but operation becomes troublesome requiring multiple taps and users unaware of the method cannot restore display

Engineering Contradiction:
Improvedisplay restoration operationVSAvoidoperation steps
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical tapping operation with a proximity detection mechanism. The detector senses when an object (such as a user's finger or another device) approaches the display, automatically triggering display restoration without requiring physical contact or knowledge of specific gestures. This substitutes the mechanical interaction model with a field-based detection model.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The display system automatically restores itself when proximity is detected, without requiring the user to know or initiate a specific restoration command. The system monitors its own state and autonomously transitions from low-luminance to normal display state based on the proximity signal, making the restoration process self-activating rather than user-commanded.

Inventive Principle:
Principle #25Self-service

2Use of energy by moving object

If display enters low-luminance state for power saving, then energy consumption is reduced, but user interaction becomes less responsive

Engineering Contradiction:
Improvedisplay power consumptionVSAvoiddisplay response speed
Core Design Contradiction:
Use of energy by moving objectVSSpeed

Solution Approach 1:

The proximity detector continuously monitors for approaching objects even when the display is in low-luminance state. This preliminary detection prepares the system for potential user interaction, so that when a user approaches, the display can restore immediately without waiting for touch input or other delayed commands. The system is pre-positioned to respond instantly to proximity events.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback loop where the detector continuously provides information about object proximity to the display controller. This real-time feedback enables the display to dynamically adjust its state based on user presence, automatically transitioning from power-saving mode to active mode when proximity is detected, and returning to power-saving mode when proximity is lost.

Inventive Principle:
Principle #23Feedback

AI summary

An image display control apparatus and method are used to detect an object that is in proximity to a display. A display controller is used to change the display from a first display state to a second display state after the object is not detected for a predetermined time period. The display state is then restored to the first display state when the detector detects the object being in proximity to the display. In another aspect, the display controller changes the display to the first display state from the second display state when the detector detects the object being in proximity to the display, where the second display state is a lower power state than the first display state.
