Solution Overview
Problem
Existing methods for reducing power consumption in electronic devices with flexible displays do not effectively consider the unique characteristics of these devices, leading to inefficient battery usage.
Innovation Solution
An electronic device with a flexible display that includes a processor to identify the current form factor of the display when the battery level is low, determine alternative form factors that reduce power consumption, and provide information to the user about these options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the brightness of the entire display is adjusted to reduce power consumption, then battery power consumption is reduced, but the solution does not consider the unique characteristics of flexible displays and cannot effectively reduce battery power consumption
Solution Approach 1:
The patent applies local quality by adjusting the brightness of specific regions of the flexible display rather than the entire display. The display is divided into multiple zones with independently controllable brightness levels, allowing high brightness in areas where content is displayed and low brightness in inactive areas, thereby reducing overall power consumption while adapting to the flexible display's unique form factor characteristics
Solution Approach 2:
The patent implements dynamics by making the display brightness adaptive and changeable based on the flexible display's current form factor state. As the flexible display bends or changes shape, the system dynamically adjusts which regions receive high brightness and which receive low brightness, optimizing power consumption for each specific configuration rather than using a fixed brightness setting
2Adaptability or versatility
If the flexible display is used in various form factors to enhance adaptability, then device versatility is improved, but power consumption increases
Solution Approach 1:
The patent resolves this contradiction by applying local quality through region-specific brightness control. When the flexible display adopts different form factors, only the necessary display regions are activated at high brightness while other regions maintain low brightness, thus preserving form factor versatility without proportionally increasing power consumption across the entire display surface
Solution Approach 2:
The patent applies partial action by activating and maintaining high brightness only in the portions of the flexible display that are currently needed for content display. When the display is in a folded or bent state, only the visible or active regions consume high power, while inactive regions consume minimal power, thus achieving versatility with optimized energy usage

AI summary
An electronic device may include a flexible display, a battery, a memory, and a processor operatively connected to the flexible display, the battery, and the memory. The processor may be configured to: when the state of charge of the battery is a specified value or less, identify a current form factor of the flexible display; determine at least one form factor of the flexible display that can reduce power consumption of the battery; and provide information on the at least one form factor of the flexible display. Various other embodiments understood through the specification are also possible.
