Dual-Panel 3D Display Mode Switching for Motion-Induced Dizziness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D image electronic devices provide only binocular disparity information, lacking monocular depth perception factors such as focus control and motion disparity, leading to user dizziness when 3D depth and image motion are significant.
Innovation Solution
An electronic device with dual display panels and a display panel driver that switches between 2D and 3D modes based on image motion and 3D depth values, using RGB-YCoCg data conversion and pixel row averaging to determine these values, ensuring appropriate image display modes to alleviate dizziness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 3D depth is increased to provide better depth perception, then depth perception capability is improved, but user dizziness occurs due to large image motion
Solution Approach 1:
The patent implements dynamic mode switching between 2D and 3D display modes based on real-time calculation of image motion values. When image motion exceeds a threshold, the system automatically switches from 3D mode to 2D mode, preventing dizziness while maintaining depth perception capability when conditions are favorable
Solution Approach 2:
The patent changes the display mode parameter (2D/3D) based on the image motion value parameter. By monitoring and comparing image motion values against thresholds, the system adjusts the depth perception parameter dynamically, resolving the contradiction between providing strong depth perception and avoiding motion-induced dizziness
2Measurement precision
If 3D depth value is large to enhance depth perception, then depth perception is improved, but dizziness is caused when combined with large image motion
Solution Approach 1:
The patent employs feedback mechanisms by continuously calculating image motion values from current and previous frame data, comparing these values against thresholds, and using this feedback to determine whether to maintain or switch display modes, thereby maintaining user comfort while preserving depth perception capability
Solution Approach 2:
The system dynamically adjusts the display mode based on real-time image motion conditions. When image motion is small, 3D mode provides enhanced depth perception; when image motion increases, the system switches to 2D mode to maintain user comfort, creating a dynamic balance between depth perception and comfort
3Loss of information
If dual display panels are used to provide different images to left and right eyes, then binocular disparity information is improved, but monocular depth perception factors are still lacking causing dizziness
Solution Approach 1:
The patent makes the display system multi-functional by enabling it to operate in both 2D and 3D modes using the same dual display panel structure. This universality allows the system to provide binocular disparity information when needed (3D mode) while switching to identical images for both eyes (2D mode) when image motion suggests dizziness risk, thus addressing the limitation of lacking monocular depth perception factors
Data Source
AI summary
An electronic device comprises a first display panel including first pixels which display a left eye image, a second display panel including second pixels which display a right eye image, and a display panel driver configured to apply a left eye data voltage to the first pixels and to apply a right eye data voltage to the second pixels. The first display panel and the second display panel are configured to operate in a 2D image mode in which the left eye image and the right eye image which are identical to each other are displayed or to operate in a 3D image mode in which the left eye image and the right eye image which are different from each other are displayed, based on an image motion value and a 3D depth value.
