Display Panel Segmented Pixel Units for Stereoscopic 3D
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies, such as color cast, polarized, and shutter displays, face issues like chromatic aberration, reduced image resolution, and high technical difficulties and costs, particularly in achieving effective stereoscopic display.
Innovation Solution
A display panel with a pixel array comprising first-type and second-type pixel units, where the drive circuit provides signals for simultaneous or staggered display modes to achieve high-definition, stereoscopic, and power-efficient 3D display without alternate high-frequency compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If color cast display method is used to achieve stereoscopic display, then 3D display effect is provided, but chromatic aberration occurs and image sharpness deteriorates
Solution Approach 1:
The pixel array is divided into first-type pixel units and second-type pixel units that are spatially separated. First-type pixel units display left-eye pictures while second-type pixel units display right-eye pictures simultaneously, eliminating the need for color filtering and avoiding chromatic aberration while maintaining image sharpness
2Adaptability or versatility
If polarized display method is used to achieve stereoscopic display, then 3D display effect is provided, but image resolution is reduced
Solution Approach 1:
The display panel uses spatial segmentation of pixel units rather than polarized filtering. Each pixel type (first-type or second-type) contributes fully to the displayed image, maintaining full resolution while providing stereoscopic effect through sequential or simultaneous display to different eyes
3Adaptability or versatility
If shutter display method is used to achieve stereoscopic display, then 3D display effect is provided, but technical difficulties and costs increase
Solution Approach 1:
The display panel dynamically switches between different display modes (first display mode for simultaneous display, second display mode for sequential stereoscopic display, third display mode for power saving). This dynamic adaptability provides stereoscopic functionality without requiring complex external shutter mechanisms, reducing technical complexity and cost
4Measurement precision
If all pixel units display simultaneously to achieve high definition, then image resolution is improved, but power consumption increases
Solution Approach 1:
In the third display mode, the pixel array alternates between displaying and not displaying. First-type pixel units display during first time periods while second-type pixel units remain off, and vice versa during other time periods. This periodic action maintains high definition when needed while significantly reducing power consumption during normal operation

AI summary
Provided are a display panel, a display device and a display method of the display panel. The display panel includes a pixel array, where the pixel array includes a plurality of pixel groups and each of the plurality of pixels group includes first-type pixel units and second-type pixel units; and a drive circuit configured to provide a drive signal for the pixel array. A display mode of the display panel includes a high-definition display mode in which within one-frame time, the first-type pixel units and the second-type pixel units collectively display a same to-be-displayed picture; a stereoscopic display mode in which the first-type pixel units display a user's left-eye picture within first time and the second-type pixel units display a user's right-eye picture within second time; and a power saving display mode in which the first-type pixel units display a picture and the second-type pixel units do not perform displaying.
