Dual Micro-Lens 3D Display Maintaining Full Pixel Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D display apparatuses using lenticular lenses reduce the actual resolution by half due to the need to alternate pixels for left-eye and right-eye signals, resulting in a lower display resolution in 3D mode compared to 2D mode.
Innovation Solution
A display apparatus with a polarization converting unit, a first micro-lens layer, and a second micro-lens layer, where the lenticular lenses are arranged in a specific configuration to maintain the same refractive direction for both left-eye and right-eye signals, allowing all pixels to contribute to image formation in both 2D and 3D modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lenticular lenses are used for 3D display, then 3D display capability is achieved, but the actual resolution is reduced to half of the pixel array resolution
Solution Approach 1:
The invention divides the pixel array into multiple groups (e.g., odd and even pixel groups) that can be independently controlled to display different eye signals. By segmenting the pixel usage, all pixels can contribute to 3D display without the 50% loss inherent in conventional alternating pixel methods, thereby maintaining full resolution while achieving 3D capability.
Solution Approach 2:
The invention introduces a new dimension of control by implementing different scanning or selection patterns for different pixel groups within the same frame period. This allows simultaneous utilization of all pixels for 3D display by varying the temporal dimension of signal assignment, rather than being constrained to spatial alternation that halves the resolution.
2Manufacturing precision
If all pixels are used to display left-eye and right-eye signals simultaneously, then full resolution is maintained, but the conventional alternating pixel method cannot be applied
Solution Approach 1:
The invention employs periodic scanning or selection actions where different pixel groups are activated in a systematic repeating pattern within each frame period. This periodic control mechanism allows all pixels to be utilized for 3D display while maintaining manageable control complexity through regular, predictable timing patterns rather than complex arbitrary control.
Solution Approach 2:
The invention implements dynamic control where the active pixel groups change over time within the frame period. By dynamically assigning different pixel groups to display left-eye or right-eye signals at different time intervals, the system achieves full pixel utilization while the dynamic nature of the control simplifies the overall system architecture compared to static alternating methods.
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 maintains the full resolution of the display panel in both 2D and 3D modes by ensuring that all pixels can display signals effectively, without reducing the resolution in 3D mode, as both left-eye and right-eye signals are refracted and directed to the user's eyes efficiently.
Implementation Method 1
the left-eye signals L are refracted and the transmission direction of the left-eye signals L is changed since a refractive index of the lenticular lenses 120 is different from a refractive index of an external medium
Implementation Method 2
The polarization converting unit is disposed on the display panel

AI summary
A display apparatus includes a display panel, a polarization converting unit, a first micro-lens layer and a second micro-lens layer. The polarization converting unit is disposed on the display panel. The first micro-lens layer is disposed on the polarization converting unit and includes a plurality of first lenticular lenses parallel with and adjacent to each other. A first adjacent edge is formed between each two adjacent first lenticular lenses. The second micro-lens layer is disposed on the first micro-lens layer and includes a plurality of second lenticular lenses parallel with and adjacent to each other. A second adjacent edge is formed between each two adjacent second lenticular lenses. The first and second lenticular lenses are extended in a same direction and have a same width. There is an interval between an axis center line of each second lenticular lens and an axis center line of each first lenticular lens.
