Stereoscopic Display Resolution via Temporal Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereoscopic image display devices using patterned retarders suffer from reduced brightness, smaller viewing angles, and lower resolution for 3D images compared to traditional 2D displays, due to the alternating display of left and right eye images at half the resolution of the display panel.
Innovation Solution
A stereoscopic image display device and driving method that includes a display panel with a patterned retarder and polarization glasses, where left eye image data is displayed on odd-numbered lines during one frame period and right eye image data is displayed on even-numbered lines, with compensation image data generated from previous frames to increase resolution by interpolating data between lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If left and right eye images are displayed alternately on odd and even numbered lines using a patterned retarder, then stereoscopic 3D images can be implemented with good polarization characteristics, but the resolution is reduced by 50% compared to the display panel resolution
Solution Approach 1:
The patent applies preliminary action by generating compensation image data in advance based on previously input image data. The compensation data for lines where no image data is input is created before the display frame, using temporal information from previous frames to fill in the missing spatial information, thereby maintaining full resolution without requiring additional hardware.
2Reliability
If patterned retarder is used to transmit polarization light rays for left and right eye images, then crosstalk is reduced and image quality is improved, but brightness for 2D images is reduced
Solution Approach 1:
The patent implements periodic action by alternating the function of each display line between 3D mode and 2D mode in successive frame periods. Odd numbered lines display 3D image data in one frame and 2D compensation data in the next frame, while even numbered lines do the opposite. This temporal multiplexing allows the patterned retarder to serve both 3D and 2D functions, improving perceived brightness for 2D content while maintaining 3D capabilities.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach effectively increases the resolution of 3D images displayed on the device by interpolating data between lines, enhancing the viewing experience by maintaining higher resolution and brightness while maintaining good up and down viewing angles.
Implementation Method 1
a patterned retarder including first retarders transmitting a first polarization light from odd numbered display lines of the display panel and second retarders transmitting a second polarization light from even numbered display lines

AI summary
Embodiments of this document provide a stereoscopic image display device and a driving method capable of preventing the reduction in resolution when 3D images are displayed on a stereoscopic image display device including a patterned retarder. According to an exemplary embodiment, in odd numbered display lines of a display panel, left eye image data input during an N-th (where N is a positive integer) frame period is displayed during the N-th frame period, and left eye compensation image data generated based on the data input during the N-th frame period is displayed during a (N+1)-th frame period, and in even numbered display lines of the display panel, right eye compensation image data generated based on data input during a (N−1)-th frame period is displayed during the N-th frame period, and right eye image data input during the (N+1)-th frame period is displayed during the (N+1)-th frame period.
