Electronic Device Power Module for Display Content During Processor Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in efficiently managing power consumption when the processor is driven, particularly in maintaining display functionality while conserving battery life, especially when the battery voltage drops below a certain threshold.
Innovation Solution
The electronic device employs a power module to interrupt power supply to non-essential components while maintaining power to the display module, allowing it to continue displaying content even when the processor is powered off, by using a control signal to manage power distribution based on battery voltage levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the processor is driven to maintain display functionality, then the display can show content, but the battery life is reduced due to increased power consumption
Solution Approach 1:
The patent segments the power supply control into two independent parts: the processor power control and the display module power control. This allows the display to operate independently from the processor, enabling the display to remain functional while the processor is powered down to conserve battery life.
Solution Approach 2:
The display module is enabled to autonomously display content without requiring continuous processor operation. The display controller can manage the display functionality independently, allowing the system to maintain display output even when the main processor is powered off, thus reducing overall power consumption.
2Use of energy by moving object
If the processor is powered off to conserve battery, then power consumption is reduced, but the display cannot update or control content
Solution Approach 1:
Content is prepared and transferred to the display module's memory in advance before the processor is powered off. This preliminary action ensures that the display has the necessary content data stored locally, allowing it to continue displaying and updating content without requiring the processor to remain active.
3Reliability
If power is supplied to non-essential components when battery voltage is low, then those components can function, but the battery drains faster
Solution Approach 1:
The patent applies local quality by providing differentiated power supply to different components based on their essentiality. The display module, being essential for information presentation, receives continued power supply even when battery voltage is low, while non-essential components are powered down. This selective power distribution maintains critical functionality while extending battery duration.

AI summary
Various exemplary embodiments of the present disclosure relate to an apparatus and method for outputting content in an electronic device. In this case, the electronic device includes a display module, a power module configured to interrupt power supply to at least one element of the electronic device based on a control signal, and a processor. The processor may be configured to transmit to the power module the control signal for interrupting the power supply to the processor if a designated condition is satisfied, and transmit content information to the display module so that the display module displays the content information when the power supply to the processor is interrupted.
