Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

3D display apparatuses face the challenge of maintaining a stable depth for on-screen display (OSD) menus while adjusting the depth of 3D images, as changes in 3D image depth can alter the perceived depth of OSDs, distracting users and disrupting their viewing experience.

Innovation Solution

A display apparatus and method that include a depth adjusting unit for 3D images and a controlling unit to maintain the OSD depth at a specific level, using techniques such as inversely applying depth adjusting values, recognizing OSD areas, and deactivating depth adjustments when necessary, ensuring the OSD remains at a consistent depth regardless of changes in the 3D image depth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the depth of 3D image is adjusted, then the 3D stereoscopic effect is improved, but the depth of OSD changes and user experience deteriorates

Engineering Contradiction:

Improve3D depth adjustment capabilityVSAvoidOSD depth stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent segments the display area into two independent zones: a 3D image display area and an OSD display area. The OSD is rendered in a separate depth space from the 3D content, allowing independent depth control. This segmentation enables the OSD to maintain stable depth while the 3D image depth is adjusted, resolving the contradiction between 3D depth adaptability and OSD depth stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of allowing the OSD to follow the 3D image depth changes, the patent inverts the approach by fixing the OSD at a reference depth position and preventing it from changing depth. The OSD depth is decoupled from the 3D image depth, so when 3D depth is adjusted, the OSD remains stationary at its reference position, eliminating the depth fluctuation problem.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If OSD depth changes with 3D image depth, then OSD is integrated with 3D content, but OSD becomes distracting and user experience worsens

Engineering Contradiction:

ImproveOSD integration with 3D contentVSAvoidOSD distraction to user

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional approach by preventing OSD depth from changing when 3D image depth is adjusted. The OSD is maintained at a fixed reference depth position, decoupled from 3D depth variations. This inversion eliminates the distracting effect of OSD depth fluctuations while preserving OSD functionality and integration with the overall display system.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent applies different depth characteristics to different regions of the display: the 3D image area allows dynamic depth adjustment for stereoscopic effect, while the OSD area maintains fixed depth for stability. This local differentiation of depth properties ensures that each region serves its intended function without interfering with the other, reducing user distraction.

Inventive Principle:

Principle #3Local quality

AI summary

A display apparatus and a method for applying an OSD applying thereto. The display apparatus maintains the depth of the OSD to be displayed on the screen at a specific depth if the depth of a 3D image is adjusted. Accordingly, even if the depth of the 3D image is adjusted, the depth of the OSD remains the same. Therefore, a user may be provided with the OSD of which depth does not change even if the depth of the 3D image is adjusted.
