Solution Overview

Problem

Existing display apparatuses are inefficient in allowing multiple users to simultaneously utilize different services on a single large screen, as they typically allow only one user to control the screen at a time, limiting the utilization of smart TV capabilities.

Innovation Solution

The method involves dividing the screen into multiple sub-screens, each bound to a different input device, allowing independent control of sub-screens by their respective input devices, enabling multiple users to use different services simultaneously on a single display apparatus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the screen is divided into multiple sub-screens and bound to different input devices, then multiple users can simultaneously use different services, but the device complexity increases

Engineering Contradiction:
Improvemulti-user service capabilityVSAvoidscreen control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display screen is segmented into multiple independent sub-screens (first sub-screen, second sub-screen, etc.), each bound to a different input device. This allows User 1 to control the first sub-screen via input device 1 while User 2 controls the second sub-screen via input device 2, enabling simultaneous independent service usage without interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display apparatus is designed to support multiple functions simultaneously by binding different sub-screens to different input devices. The system can handle broadcast content, web browsing, games, and other applications on different sub-screens at the same time, making a single device serve multiple users with diverse needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If only one service is provided at a time on the smart TV screen, then control is simple, but the capabilities of the smart TV are not sufficiently utilized

Engineering Contradiction:
Improvesmart TV capability utilizationVSAvoidscreen control simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

By dividing the single screen into multiple sub-screens, the system enables simultaneous execution of multiple services (broadcast content, web browser, games, etc.) that were previously mutually exclusive. Each sub-screen can run independent applications, fully utilizing the smart TV's multi-processing capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sub-screen binding mechanism acts as an intermediary that maps input devices to specific display regions. This mediator layer manages the complexity of multi-service control while presenting a simplified interface to users, who only need to control their assigned sub-screen without worrying about other running services.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Provided is a method of displaying and controlling a plurality of sub-screens on a display apparatus. A plurality of sub-screens of a preset number are displayed on a screen of the display apparatus, and the sub-screens are respectively bound to different input devices, and a control instruction sent from the input devices to the display apparatus independently controls only a sub-screen bound to a particular input device, and does not affect other sub-screens that are not bound to the particular input device. A user of a display may use various services at the same time via the plurality of independent sub-screens displayed on the screen of the display apparatus, and a plurality of users may share a large screen of the display apparatus and view respectively desired content at the same time.
