Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic image display devices using binocular parallax can cause user dizziness when continuously viewing three-dimensional images, and display devices using non-binocular parallax methods may result in image distortion.
Innovation Solution
A display device with a bent display panel comprising first and second regions at a predetermined angle, an optical module with an inclined surface to reflect and transmit light, and a panel driver performing pixel shift operations to shift images in opposite or same directions to prevent distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If binocular parallax is used to display three-dimensional images, then depth perception is achieved, but user dizziness occurs when continuously viewing
Solution Approach 1:
The display panel is divided into multiple display regions positioned at different distances from the user. Each region displays images at different focal lengths, segmenting the depth perception task across multiple spatial zones rather than relying on a single binocular parallax mechanism, thereby reducing visual strain and dizziness during continuous viewing
Solution Approach 2:
The invention transitions from traditional binocular parallax (operating in the horizontal dimension) to a multi-dimensional approach by positioning display regions at different distances along the depth axis. This adds a longitudinal dimension to stereoscopic display, allowing depth perception through focal length differences rather than just horizontal image separation
2Ease of operation
If pixel shift operation is performed in conventional display devices, then image positioning is adjusted, but image distortion occurs
Solution Approach 1:
Different pixel shift operations are applied to different display regions based on their specific characteristics. Each region undergoes independent image processing tailored to its position and function, allowing precise control over image positioning in each zone while maintaining overall image integrity and avoiding distortion
Solution Approach 2:
Image data is pre-processed with appropriate pixel shift adjustments before being sent to each display region. By performing the positioning adjustment in advance during the data processing stage rather than during actual display, the system achieves accurate image positioning without introducing real-time distortion
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The display device effectively displays three-dimensional images without causing user dizziness or distortion by shifting images in coordinated directions, using a pixel shift operation that maintains image clarity and depth perception.
Implementation Method 1
an optical module which reflect slight emitted from the first display region, and transmits light emitted from the second display region
Implementation Method 2
a beam splitter including an inclined surface, where to the beam splitter divides light emitted from each of the first and second display regions and incident on the inclined surface into reflected light and transmitted light

AI summary
A display device includes a display panel including a first display region, and a second display region positioned at a predetermined angle with respect to the first display region, an optical module which reflects light emitted from the first display region, and transmits light emitted from the second display region, and a panel driver which drives the display panel, where the panel driver performs a pixel shift operation in a way such that first and second images respectively displayed in the first and second display regions are shifted in opposite directions along a first direction, and are shifted in a same direction along a second direction substantially perpendicular to the first direction.
