Solution Overview

Problem

Existing mobile terminals face user inconvenience when events occur during content display, as part of the screen is obscured, making it difficult to view detailed information related to the event without complex manipulations.

Innovation Solution

A mobile terminal with a transparent display unit featuring first and second transparent substrates, where content is displayed on one substrate and event-related information is shown on the other, allowing users to view both without obstruction by rotating the terminal body, with the controller sensing motion and orientation to switch the display accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If event information is displayed on the same screen as content, then users can access event information, but the content display screen is obscured and user convenience deteriorates

Engineering Contradiction:
Improveevent information accessibilityVSAvoiduser convenience
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display unit is divided into two separate transparent substrates: a first transparent substrate for displaying content and a second transparent substrate for displaying event information. This segmentation allows both types of information to be displayed simultaneously without obscuring each other, resolving the contradiction between information accessibility and user convenience.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-plane display to a multi-plane display structure where content and event information are displayed on different transparent substrates stacked in the thickness direction. Users can view both types of information by rotating the terminal body, adding a rotational dimension to the display interaction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If a single display screen is used for both content and event information, then device complexity is reduced, but information display completeness deteriorates

Engineering Contradiction:
Improvedisplay structure simplicityVSAvoidinformation display completeness
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent merges multiple display functions (content display and event information display) into a single integrated transparent display unit composed of stacked transparent substrates. This combining approach maintains relative structural simplicity while enabling complete information display through the multi-substrate configuration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display unit employs a composite structure of multiple transparent substrates (first transparent substrate and second transparent substrate) with different display functions. This composite material approach allows each substrate to be optimized for its specific function while maintaining overall transparency and visual accessibility.

Inventive Principle:
Principle #40Composite materials

3Loss of information

If transparent display substrates are used for both content and event information, then information visibility is improved, but device complexity increases

Engineering Contradiction:
Improveinformation visibilityVSAvoiddisplay unit structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Both the first transparent substrate and the second transparent substrate are designed with universal touch input functionality and similar structural characteristics. This multi-functionality design allows the system to handle different display tasks using the same fundamental technology platform, reducing the complexity increase that would result from using fundamentally different technologies.

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

AI summary

The present invention relates a mobile terminal capable of controlling contents displayed on a display unit, and a control method thereof. A mobile terminal according to one exemplary embodiment includes a terminal body, a transparent display unit having first and second transparent substrates both configured to sense touch inputs, a sensing unit to sense at least one of motion and rotation of the terminal body, and a controller to determine whether or not the sensed at least one of the motion and the rotation of the terminal body meets a preset condition information when an event is generated while a content is output on the first transparent substrate, and decide whether or not to display information relating to the generated event on the second transparent substrate based on the determination result.
