Solution Overview

Problem

Electronic devices face power consumption issues and freezing problems when displaying play screens with multiple dynamic elements, as reducing the screen refresh rate to conserve power can cause important dynamic elements to be discarded and not displayed, leading to a frozen playback experience.

Innovation Solution

An electronic device method that determines the area proportion and frame rate of dynamic elements on a play screen, reducing the frame rate of less attractive dynamic elements to conserve power while ensuring more attractive elements are updated at their original frame rate, thereby reducing the likelihood of freezing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the screen refresh rate is reduced to reduce power consumption, then power consumption is reduced, but dynamic elements may be discarded and not displayed, causing freezing

Engineering Contradiction:
Improvepower consumptionVSAvoiddisplay smoothness
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent segments the screen elements into different categories (video elements, dynamic elements, static elements) and applies different refresh rate strategies to each segment. Video elements maintain their original frame rates, while dynamic elements have their frame rates adjusted based on area proportion thresholds, allowing selective optimization without compromising overall display quality

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by treating different regions of the screen differently based on the area proportion of dynamic elements. When dynamic elements occupy a small area (below threshold), their frame rates are reduced to save power. When they occupy a large area (above threshold), their frame rates are maintained to ensure display smoothness, creating a localized optimization strategy

Inventive Principle:
Principle #3Local quality

2Use of energy by moving object

If the frame rate of dynamic elements is reduced to save power, then power consumption is reduced, but the display of these elements may freeze

Engineering Contradiction:
Improvepower consumptionVSAvoiddisplay fluency
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent dynamically changes the frame rate parameter of dynamic elements based on the area proportion threshold. By adjusting this parameter selectively for different dynamic elements based on their screen occupancy, the system optimizes power consumption while maintaining display fluency for elements that require it

Inventive Principle:
Principle #35Parameter changes

AI summary

A method for displaying a play screen and an electronic device relate to the field of terminal technologies to reduce power consumption of an electronic device. The method includes: determining, by the electronic device based on a preset condition, whether the screen element in the play screen includes a second dynamic element, where the second dynamic element has a second frame rate, and the preset condition includes that: an area proportion of the second dynamic element in the play screen is less than a preset threshold, and the second frame rate is greater than the first frame rate; and when the screen element in the play screen includes the second dynamic element, displaying, by the electronic device, the play screen of the foreground application at the first frame rate.
