Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spatial-multiplexed stereo-display technologies reduce display resolution, as they require different image information for each eye, limiting the ability to achieve high-resolution 3D images.
Innovation Solution
A display device with a liquid crystal lens that alternately forms different lens units by driving adjacent electrodes at different time periods, synchronized with the display panel, to enable full resolution stereo image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spatial-multiplexed stereo-display technology is applied using column lens or parallax barrier, then stereo image display is achieved, but display resolution is reduced
Solution Approach 1:
The liquid crystal lens alternates between different lens unit configurations at different time periods. During a first time period, first lens units are formed to guide light from odd display units. During a second time period, second lens units are formed to guide light from even display units. This periodic switching enables full-resolution stereo display by temporally separating the viewing paths for left and right eyes.
Solution Approach 2:
The liquid crystal lens dynamically reconfigures its lens units based on driving electrode activation. By selectively driving adjacent driving electrodes at different time periods, the lens transitions between different optical states, creating first lens units aligned with odd display units and second lens units aligned with even display units, thereby achieving temporal multiplexing without spatial resolution loss.
2Manufacturing precision
If adjacent driving electrodes are driven at different time periods, then full resolution stereo image is achieved, but switching frequency requirement increases
Solution Approach 1:
The system employs periodic switching of adjacent driving electrodes at different time periods within each frame. Odd driving electrodes are activated during a first time period to form first lens units, while even driving electrodes are activated during a second time period to form second lens units. This periodic alternation achieves full-resolution stereo display while maintaining manageable switching frequency requirements through temporal division.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for full resolution stereo image display by ensuring that each display unit can emit light towards different directions at different time periods, maintaining the total image resolution equivalent to the display panel, even in stereo mode, with switching frequencies greater than or equal to 120 Hz.

AI summary
A display device including a liquid crystal lens and a display panel is provided. The liquid crystal lens is disposed above the display panel and includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first and the second substrates, driving electrodes located between the first substrate and the liquid crystal layer and arranged in a pitch, and an opposite electrode layer located between the second substrate and the liquid crystal layer. The display panel has display units arrange in the pitch. In a 3D display mode, two adjacent driving electrodes in the liquid crystal lens are respectively driven at a first time period and a second time period. The liquid crystal lens and the display panel are switched synchronically so that each display unit respectively displays images with different parallax at the first and the second time periods.
