Solution Overview
Problem
Conventional three-dimensional image display systems, particularly those using polarization principles, face challenges in achieving high resolution without significant cost increases and are limited in providing multiple view points, restricting their utility in both two-dimensional and three-dimensional image displays.
Innovation Solution
A display system utilizing a polarizer and display panel with pixels exhibiting orthogonal polarization states, allowing for twice the conventional resolution without increasing system size, and enabling seamless switching between two-dimensional and stereoscopic or autostereoscopic three-dimensional image displays, including multi-view points without reducing unit view point resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional polarization display systems are used to achieve three-dimensional image display, then stereoscopic effect is provided, but display resolution is reduced by half compared to conventional two-dimensional displays
Solution Approach 1:
The display panel is divided into multiple sub-pixels within each pixel unit, specifically implementing a 2x2 arrangement of sub-pixels (R1, G1, B1, R2, G2, B2) that can be independently controlled. This segmentation allows the system to provide both high-resolution two-dimensional display (using all sub-pixels) and three-dimensional display (directing specific sub-pixels to left and right eyes) without sacrificing resolution
Solution Approach 2:
The patent introduces a temporal dimension by alternating between left-eye and right-eye image frames at different time points. The display controller switches the polarization state of each sub-pixel between frames, enabling the human visual system to perceive three-dimensional depth through temporal multiplexing while maintaining spatial resolution
2Measurement precision
If high-resolution display systems are developed to improve display resolution, then resolution is improved, but system cost increases enormously
Solution Approach 1:
Instead of manufacturing a single high-resolution display panel, the patent segments one pixel into multiple lower-cost sub-pixels (2x2 arrangement). This allows the system to achieve equivalent or higher effective resolution through clever optical control and pixel arrangement rather than through expensive high-density manufacturing
Solution Approach 2:
The display panel with segmented sub-pixels serves multiple functions: it can display high-resolution two-dimensional images by utilizing all sub-pixels, provide stereoscopic three-dimensional display by directing specific sub-pixels to different eyes, and support various polarization modes. This multi-functionality eliminates the need for separate high-resolution and three-dimensional display systems, reducing overall cost
3Adaptability or versatility
If conventional three-dimensional display systems are used, then stereoscopic effect is achieved, but the system is limited to only two view points reducing utilization
Solution Approach 1:
The patent implements dynamic control of polarization states for each sub-pixel through a display controller that can independently adjust the polarization direction of different sub-pixels. This dynamic control allows the system to flexibly configure multiple view points by directing different sub-pixel groups to different viewing angles, transforming a static two-viewpoint system into a dynamic multi-viewpoint system without proportionally increasing hardware complexity

AI summary
Disclosed is a display system capable of providing two and three-dimensional images. The display system comprises display means; a first polarizer located at a distance from a front surface of the display means; a display panel provided to a front of the first polarizer and regulating a polarization direction of light having passed through the first polarizer; and a second polarizer located at a distance from a front surface of the display panel, wherein each pixel of the second polarizer has a size of dividing a unit pixel of the display panel into two parts and two polarization states of each pixel are orthogonal to each other. By applying the structure, it is possible to manufacture a display system having a resolution increased by two times, as compared to a conventional display system. Accordingly, when developing a high resolution image display system requiring enormous development costs, it is possible to manufacture it using the two types of display systems. As a result, it is possible to inexpensively manufacture a high resolution and high definition display system. Further, it is possible to provide a three-dimensional image without decreasing the resolution of the display system, and to provide the multi-view points twice as many as the conventional multi-view points, without decreasing the unit view point resolution of the three-dimensional image.
