Display Panel Segmentation for 3D Viewing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The viewing angle of 3D polarized display devices is reduced due to the decreasing width of black matrices, and existing methods to increase it either compromise yield and reliability or introduce moire patterns.
Innovation Solution
A display panel design with display pixels arranged in an array and black matrices, where the width of the first display area is smaller than the interval between black matrices, and additional display areas with independent luminance control, along with phase delay layers and filters, to enhance the viewing angle without introducing additional patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the width of black matrices is decreased to increase display area, then the display area is increased, but the viewing angle is reduced
Solution Approach 1:
The display area is segmented into first display areas (for images) and second display areas (for light emission only), with black matrices strategically positioned between them. This segmentation allows the second display areas to compensate for viewing angle limitations by emitting light that fills in angular gaps, thereby maintaining wide viewing angles even as black matrix width is reduced.
Solution Approach 2:
The patent introduces a temporal dimension by alternately driving first and second display areas to display different images (left-eye and right-eye views for 3D display). This time-based multiplexing allows the system to maintain wide viewing angles through sequential activation of different display regions, effectively adding a time dimension to the spatial arrangement.
2Adaptability or versatility
If existing methods are used to increase viewing angle, then the viewing angle is improved, but yield and reliability are compromised
Solution Approach 1:
Different regions of the display are assigned different functions: first display areas are optimized for image display with appropriate black matrix spacing, while second display areas are optimized for light emission to enhance viewing angle. This local differentiation allows each region to perform its specific function optimally without compromising overall reliability or requiring complex global adjustments that would reduce yield.
3Adaptability or versatility
If existing methods are used to increase viewing angle, then the viewing angle is improved, but moire patterns are introduced
Solution Approach 1:
The patent extracts the light emission function from the traditional uniform display structure and isolates it in second display areas that are driven independently. By separating the image display function (first display areas) from the light emission function (second display areas), the system avoids the interference patterns and moire effects that arise from attempting to modify the entire display structure uniformly.
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 design increases the viewing angle of 3D polarized display devices while maintaining reliability and avoiding moire patterns, allowing for a more ideal 3D image experience.
Implementation Method 1
the phase delay layer comprises first phase delay units and second phase delay units alternately arranged in the first direction; light phase delay by the first phase delay units differs from light phase delay by the second phase delay units by (2n−1) π
Implementation Method 2
3D (three-dimensional) polarized display technology is widely used in current 3D display devices and systems
Implementation Method 3
a light transmission spectrum of the second filters does not overlap with a light transmission spectrum of the first filters
Data Source
AI summary
A display panel and a driving method for the same, and a display device are disclosed. The display panel includes a plurality of display pixels arranged in a first array and black matrixes. Each display pixel includes a first display area; and each black matrix is disposed between two adjacent first display areas. A width of the first display area in a first direction on an array arrangement plane of the first array is smaller than an interval in the first direction between two black matrixes which are adjacent in the first direction.
