Display Device Local Feedback Logic for Power-Reduced Source Image Provider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing systems face delays in responding to user input due to the need to power up components like the source image provider after being put into a reduced power mode, leading to a perceived unresponsiveness, especially when updating image content is required quickly.
Innovation Solution
Implementing local user feedback generation logic on the display that allows for immediate changes to the static image or audio content without requiring the source image provider to exit its reduced power mode, enabling near-instantaneous user feedback while the system prepares to provide updated image content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the source image provider is put into reduced power mode to conserve battery life, then energy consumption is reduced, but the system response time to user input increases
Solution Approach 1:
The patent segments the feedback generation function into two parts: simple visual feedback is generated locally by the display device without requiring the source image provider to wake up, while complex updated image content still requires the source image provider. This segmentation allows the system to provide immediate feedback for simple operations while conserving battery life, and only activates the power-consuming source image provider when necessary for complex updates.
Solution Approach 2:
The patent implements preliminary action by pre-processing and storing image content data in the frame buffer before the source image provider enters reduced power mode. This allows the display device to quickly retrieve and display updated content or generate feedback images without waiting for the source image provider to wake up and process requests, thereby reducing perceived response time while maintaining battery savings.
2Speed
If the source image provider remains active to provide immediate updated image content, then system responsiveness is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial action by providing only the necessary amount of image content update rather than full updates for every user interaction. When the source image provider is in reduced power mode, the system generates minimal feedback images locally rather than activating the provider for every interaction, thus consuming less energy while still providing responsive feedback for common operations.
3Loss of energy
If additional components are powered down during static screen conditions to increase power savings, then energy efficiency is improved, but the perceived system responsiveness deteriorates
Solution Approach 1:
The patent introduces the display device as an intermediary that can generate feedback images locally without requiring the source image provider to be active. This intermediary capability allows the system to maintain perceived responsiveness by providing immediate visual feedback even when the main processing components are in reduced power mode, thus resolving the contradiction between power savings and perceived responsiveness.

AI summary
An apparatus and a method for responding to user input by way of a user interface for an apparatus that employs a display detect user input associated with the display during a static screen condition on the display wherein a static image provided by a source image provider is displayed on the display. In response to detecting the user input, the method and apparatus provide user feedback by incorporating a first type of change to the static image displayed on the display while the source image provider is in a reduced power mode wherein a standby power is available to the source image provider and communicate control information to the source image provider. The method and apparatus receive from the source image provider updated image content based on the communicated control information.
