Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic image display devices face challenges in maintaining a strong stereoscopic effect due to the characteristics of liquid crystal displays, where the images for the left and right eyes are not clearly distinguished, leading to decreased display quality.
Innovation Solution
A stereoscopic image display device that inserts a third image with predetermined luminance between the images for the left and right eyes, applying different data voltages to overlapping and non-overlapping pixels to clearly distinguish and enhance the stereoscopic effect, using a liquid crystal panel and backlight unit, and optionally synchronized spectacles with IR or wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical autostereoscopic image display device uses lenticular lenses on a liquid crystal display, then the viewer can directly view the screen without additional glasses, but the image transmitted to the right eye and the image transmitted to the left eye are not distinctly distinguished, resulting in decreased stereoscopic effect
Solution Approach 1:
The display device segments the pixel array into distinct regions: first pixel regions for transmitting images to the left eye, second pixel regions for transmitting images to the right eye, and third pixel regions positioned between them. This spatial segmentation allows clear distinction between left and right eye images while maintaining direct viewing capability without glasses.
Solution Approach 2:
Different data voltages are applied to different pixel regions based on their specific functions. The first pixel regions receive voltages optimized for left eye image transmission, the second pixel regions receive voltages optimized for right eye image transmission, and the third pixel regions receive voltages that create intermediate luminance levels. This local differentiation enhances image distinction while preserving stereoscopic effect.
2Reliability
If a typical stereoscopic image display device uses polarization or time divisional schemes, then the image transmitted to the right eye and the image transmitted to the left eye are clearly distinguished with strong stereoscopic effect, but additional glasses must be worn, increasing cost and reducing viewing convenience
Solution Approach 1:
The invention extracts and removes the requirement for additional glasses by implementing the image distinction function directly within the display device's pixel structure. The spatial arrangement and voltage control of different pixel regions inherently separate left and right eye images, eliminating the need for external optical components like polarizing filters or shutter glasses.
Solution Approach 2:
The third pixel regions positioned between the first and second pixel regions act as intermediaries. These regions display images with intermediate luminance levels that facilitate smooth transitions and enhance the distinction between left and right eye images without requiring external optical mediators like glasses.
3Reliability
If different data voltages are applied to overlapping and non-overlapping pixels to display substantially the same luminance, then the images for left and right eyes are clearly distinguished, but the device complexity increases due to amended input data processing
Solution Approach 1:
The control unit performs preliminary processing of input data before it reaches the pixel regions. By pre-calculating and amending the data voltages for the first, second, and third pixel regions based on their specific functions, the system simplifies the real-time control process and reduces the complexity of dynamic voltage adjustment during operation.
Solution Approach 2:
The invention changes the luminance parameter of pixels in the third regions to intermediate levels between the first and second pixel regions. This parameter adjustment creates a gradual luminance transition that enhances image distinction while using simple voltage modulation rather than complex processing circuits.
