Solution Overview

Problem

Current display devices lack the ability to dynamically modify their display area based on the visual attributes of the images output, limiting user interaction and experience, especially for visually impaired users who would benefit from tactile representation.

Innovation Solution

A display device and method that analyze visual attributes of images to determine modification target areas, allowing the display area to be dynamically adjusted based on these attributes, enabling a more realistic and three-dimensional output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display area is fixed and preset, then the device structure is simple, but the adaptability to different image characteristics and user needs is poor

Engineering Contradiction:
Improveadaptability to image characteristicsVSAvoiddisplay area modification capability
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display device enables dynamic modification of the display area based on visual attribute analysis. The controller dynamically adjusts the display area boundaries, modification degrees, and tactile feedback parameters according to the analyzed image characteristics, transforming a static display system into an adaptive one that responds to content requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters simultaneously: the display area parameters (position, size, shape), the modification degree parameters (protrusion depth, curvature), and the tactile feedback parameters (vibration frequency, intensity). These parameter changes are coordinated based on visual attribute analysis to achieve optimal display and tactile representation.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the display area is modified based on visual attributes, then the tactile representation quality improves, but the processing time and computational load increase

Engineering Contradiction:
Improvetactile representation accuracyVSAvoidimage processing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The controller divides the display area into multiple regions based on visual attribute analysis, identifying modification target areas separately from non-target areas. This segmentation allows selective application of tactile modification only where needed, reducing overall processing time while maintaining high tactile representation accuracy in critical regions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies partial modification to the display area by identifying specific modification target areas rather than modifying the entire display. The modification degree is adjusted based on the importance and visual attributes of different regions, applying full modification only where necessary and reduced or no modification in other areas, thereby optimizing processing efficiency.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

In a display device, an image may be three-dimensionally output by modifying a display area corresponding to an area selected based on a visual attribute of the image to be output on a display unit of the display device. The display device may include a display unit configured such that at least one portion of the display unit is modified, and a controller configured to display an output target image on the display unit and control to modify the display unit based on a visual attribute of a portion of the output target image. The controller may be configured to determine a modification target area in the output target image based on the visual attribute of components included in the output target image, and modify a display area of the display unit corresponding to the determined modification target area.
