Solution Overview
Problem
Three-dimensional displays using polarized glasses often suffer from reduced resolution and flicker phenomena, particularly in spatial-multiplexed types, which affect display quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spatial-multiplexed type three-dimensional display is used, then flicker phenomenon is prevented, but resolution is reduced by 50%
Solution Approach 1:
The invention divides the display panel into multiple sub-pixels (red, green, blue sub-pixels for left eye and red, green, blue sub-pixels for right eye) within each pixel unit. This segmentation allows simultaneous display of left and right eye images in different spatial regions, achieving spatial multiplexing that prevents flicker while maintaining full resolution through the liquid crystal phase modulator.
Solution Approach 2:
The liquid crystal phase modulator acts as an intermediary component between the display panel and the polarized glasses. It introduces phase retardation to modify the optical path of light, enabling the system to maintain resolution while preventing flicker by controlling the phase relationship between left and right eye images.
2Adaptability or versatility
If polarized glasses are used for three-dimensional display, then three-dimensional effect is achieved, but resolution is reduced
Solution Approach 1:
The invention applies different phase retardation characteristics to different regions of the display panel through the liquid crystal phase modulator. Each sub-pixel region (left eye vs. right eye) receives appropriate phase modulation to work with the corresponding lens in the polarized glasses, maintaining local optical quality that preserves resolution while enabling three-dimensional effect.
Solution Approach 2:
The liquid crystal phase modulator changes the optical phase parameter of light passing through different regions of the display panel. By introducing controllable phase retardation, the system modifies the optical properties to work synergistically with the polarized glasses, achieving three-dimensional effect without the 50% resolution loss of conventional approaches.
3Adaptability or versatility
If time-multiplexed type is used, then three-dimensional effect is achieved, but flicker phenomenon occurs
Solution Approach 1:
The invention transitions from time-multiplexed to spatial-multiplexed approach by utilizing the liquid crystal phase modulator to create phase differences in the optical dimension. This allows simultaneous display of left and right eye images in space rather than alternating them in time, achieving three-dimensional effect without flicker.

AI summary
A three-dimensional display for the viewer to watch through glasses is provided, wherein the glasses have two lenses and the polarized directions thereof are perpendicular to each other. The three-dimensional display includes a display panel and a liquid crystal phase modulator. The display panel, suitable for displaying an image, has a plurality of pixels arranged in array and a polarizer having a transmission axis, wherein the polarizer disposed between the pixels and the glasses. The liquid crystal phase modulator suitable for providing phase retardation includes a liquid crystal layer and an alignment layer adjacent to the display panel. An included angle between an alignment direction of the alignment layer and the transmission axis is substantially equal to n×45 degrees, wherein an absolute value of n is an integer. The liquid crystal phase modulator adjusts a phase of the image and then outputs an image with three-dimensional information.
