Foldable Display Power Control in Partially Folded Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face challenges in power management when placed in a partially folded state, as existing technologies do not efficiently control display power consumption based on the device's configuration.
Innovation Solution
The electronic device includes a flexible display with a housing that can be in flat, partially folded, and fully folded states, featuring separate display driving circuits for each area, and a processor that adjusts the power consumption based on the device's orientation, ensuring one area consumes less power than the other based on its alignment with the ground plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is divided into multiple areas with separate driving circuits, then the display can be controlled in different states (flat, partially folded, fully folded), but the device complexity increases
Solution Approach 1:
The display is divided into multiple areas (first area and second area) with separate display driving circuits for each area. This segmentation allows independent control of each display area, enabling the display to function in different states (flat, partially folded, fully folded) according to the device configuration.
2Use of energy by moving object
If power consumption is not optimized based on display orientation, then the display can operate uniformly, but energy efficiency deteriorates
Solution Approach 1:
Different power consumption levels are applied to different display areas based on their orientation relative to the ground plane. The first display driving circuit and second display driving circuit are configured to operate at different power consumption levels, optimizing energy efficiency by reducing power consumption in areas that are more closely aligned with the ground plane.
3Ease of operation
If the device is used in partially folded state, then portability is improved, but display power management becomes more challenging
Solution Approach 1:
The display driving circuits are dynamically configured based on the device state (flat, partially folded, or fully folded). The processor determines the device state and adjusts the operation of the display driving circuits accordingly, enabling effective power management in the partially folded state while maintaining portability.

AI summary
An electronic device is provided. The electronic device includes a first display driving circuit configured to control the first area of the flexible display, a second display driving circuit configured to control the second area of the flexible display, a processor, and a memory storing instructions, which when executed by the processor, cause the electronic device to: while the housing is in the flat state, display a first execution screen, corresponding to a first application, on the first area and the second area of the flexible display, while the first execution screen, corresponding to the first application, is displayed on the first area and the second area of the flexible display, identify the housing being moved from flat state to the partially folded state, based at least on the housing being moved from the flat state to the partially folded state, display a second execution screen corresponding to the first application, different from the first execution screen, on the first area and the second area of the flexible display, and while the second execution screen is displayed in the partially folded state, control the first display driving circuit and the second driving circuit such that one of the first area and the second area of the flexible display, which is more closely aligned with a ground plane, consumes electrical power less than electrical power consumed by the other one of the first area and the second area of the flexible display.
