Multimedia Display Area Segmentation for Black-Edge Reduction

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional display technologies for touchscreen devices result in poor display effects due to black edges when screen sizes mismatch multimedia content, and operation views are often superimposed on multimedia information, complicating user interactions.

Innovation Solution

Separate the display of multimedia information and operation views into distinct areas on the screen, adjusting the display manner based on screen and content size differences, using fixed or folded/shrunk formats to optimize area utilization and simplify user interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If operation view is superimposed on multimedia information for display, then screen space utilization is improved, but display effect deteriorates

Engineering Contradiction:

Improvescreen space utilizationVSAvoiddisplay effect

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The display screen is segmented into multiple display areas, with the first display area dedicated to multimedia information and the second display area dedicated to operation views. This spatial segmentation prevents superposition while ensuring full utilization of screen space, resolving the contradiction between screen space utilization and display effect.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If operation view is superimposed on multimedia information, then ease of operation is improved, but user experience deteriorates

Engineering Contradiction:

Improveease of operationVSAvoiduser experience

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of superimposing operation views on multimedia information in the same spatial dimension, the patent places them in separate display areas, effectively using spatial dimensioning to avoid visual interference while maintaining operational accessibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If black areas are filled when screen size does not match multimedia information, then display compatibility is improved, but screen space utilization deteriorates

Engineering Contradiction:

Improvedisplay compatibilityVSAvoidscreen space utilization

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent dynamically adjusts the display configuration based on the relationship between screen size and multimedia information size. When sizes match, full-screen display is used; when they don't match, the system transitions to a multi-area display mode that eliminates black areas by placing operation views in previously unused spaces, thus adapting to different conditions while maximizing screen utilization.

Inventive Principle:

Principle #15Dynamics

AI summary

This application provides a display control method and apparatus, and the method includes: separately obtaining first size information of a display screen of an electronic device, second size information of to-be-played multimedia information, and an operation view used to control the multimedia information; determining, based on the first size information and the second size information, a first area that is on the display screen and in which the multimedia information is displayed; and displaying the operation view in a second area other than the first area on the display screen. In the display control method and apparatus provided in this application, a display effect of a picture can be effectively improved.
