Dual-Pixel 3D Display with Polarizing Films
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current large-scale polarizing 3D electronic displays suffer from visual flickering due to rapid image-switching, leading to visual fatigue and low compatibility with 2D displays, and have low resolution due to physical pixels only emitting light for either the left or right eye.
Innovation Solution
A large-scale polarizing 3D electronic display system with two individual electronic pixels in each physical pixel, each capable of emitting light for the left and right eyes with three primary colors, and utilizing polarizing films with specific orientation to separate images, eliminating the need for shutter glasses and maintaining high resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical pixels are arranged in alternate rows or columns for 3D display, then stereoscopic effect is achieved, but resolution is reduced due to one pixel per eye
Solution Approach 1:
Each physical pixel is segmented into two independent electronic pixels (left-eye pixel and right-eye pixel), allowing each pixel to independently control light emission for respective eyes. This segmentation enables full resolution for both eyes simultaneously without requiring alternate row/column arrangements that would halve the effective resolution.
Solution Approach 2:
The patent transitions from spatial arrangement (alternate rows/columns) to a dual-pixel architecture within each physical pixel location. By adding the dimension of independent dual-subpixel control within each physical pixel, the system achieves full resolution stereoscopic display without sacrificing pixel density.
2Reliability
If shutter mode glasses are used for 3D display, then stereoscopic effect is achieved, but visual flickering and fatigue occur due to rapid image switching
Solution Approach 1:
The patent extracts the image switching function from the display system and relocates it to the polarizing filter layer. Instead of rapidly switching images on the display and using shutter glasses to block/unblock light, the system continuously displays both left and right eye images simultaneously and uses polarizing filters to direct appropriate images to each eye, eliminating flicker and the need for active shutter glasses.
Solution Approach 2:
Polarizing films are introduced as an intermediary between the display and the viewer's eyes. These films passively separate the light paths for left and right eyes based on polarization orientation, replacing the active electronic shutter mechanism with a passive optical mediator that continuously transmits appropriate images without switching.
3Adaptability or versatility
If polarizing films are applied to achieve 3D effect, then stereoscopic display is achieved, but compatibility with 2D display is reduced
Solution Approach 1:
The display system is designed with universal functionality to operate in both 3D and 2D modes. By controlling the polarization state and using appropriate viewing glasses, the same display can provide high-quality stereoscopic 3D images or function as a standard 2D display, maintaining full image quality and resolution in either mode without compromise.
