Solution Overview

Problem

When multiple windows are displayed on an electronic device, information that the user does not pay attention to occupies excessive visible and operable space, reducing screen utilization and user experience.

Innovation Solution

The electronic device determines a 'hot region' based on the display region of response controls within a window, reducing non-essential display content to increase the operable region and maintain the size of the window's visible space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all display content is shown in the window, then information completeness is improved, but operable space and screen utilization deteriorate

Engineering Contradiction:
Improveinformation completenessVSAvoidoperable space
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display content is segmented into hot region (important/interactive content) and non-hot region (less important content). The hot region maintains full visibility and operability, while the non-hot region is reduced or obscured, allowing users to access complete information selectively without occupying the entire operable space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the display window are assigned different quality levels. The hot region receives full rendering and interaction capabilities, while the non-hot region is rendered with reduced quality or obscured, creating a gradient of information accessibility that optimizes both information completeness and operable space utilization.

Inventive Principle:
Principle #3Local quality

2Productivity

If window size is reduced to free up space, then screen utilization is improved, but visible information and operability deteriorate

Engineering Contradiction:
Improvescreen utilizationVSAvoidvisible information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The window is segmented into a visible hot region that maintains adequate size for information display and a reduced non-hot region. This segmentation allows the window to effectively occupy less screen space while still providing complete information access in the hot region, thereby improving screen utilization without sacrificing visible information quality.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If non-essential content is reduced, then operable space is improved, but display content completeness deteriorates

Engineering Contradiction:
Improveoperable spaceVSAvoiddisplay content completeness
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

Non-essential content is extracted from the main display area and placed in the reduced non-hot region. This extraction allows the hot region to maintain full operable space for essential interactions, while non-essential content remains accessible but occupies minimal space, effectively resolving the contradiction between operable space and content completeness.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Embodiments of this application provide a window display method and a related apparatus. The method includes: An electronic device displays a first window. The electronic device determines a hot region of the first window based on a first display region of the first window, where the first display region includes a display region of a response control in the first window, and the response control is a control capable of responding to a touch operation. According to embodiments of this application, the hot region of the window can be determined based on a display region of display content in the window. In this way, an operable region for a user on a display screen is increased, and screen utilization is effectively improved.
