Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D displays with phase retardation films reduce brightness and viewing angle range when displaying 2D images due to the need for a black matrix to prevent incorrect image presentation, increasing hardware costs.
Innovation Solution
A 3D display with a phase retardation film where all regions have the same transmittance, eliminating the need for a black matrix, and using first and second retardation regions with different phase retardations to achieve high brightness and wide viewing angles for both 2D and 3D image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a black matrix is disposed between the two types of phase retardation regions to prevent incorrect image presentation, then the reliability of 3D image display is improved, but the brightness and viewing angle range are greatly reduced
Solution Approach 1:
The invention extracts and removes the black matrix component from the display structure. By eliminating this light-blocking element, the patent achieves both high brightness and correct 3D image presentation without requiring the traditional black matrix solution.
Solution Approach 2:
The invention applies different phase retardation properties to different regions of the phase retardation film. The first and second phase retardation regions have different retardation characteristics that are specifically tailored to guide light from different pixel types to the correct viewing direction, replacing the need for uniform black matrix blocking.
2Reliability
If a black matrix is disposed between the two types of phase retardation regions to prevent incorrect image presentation, then the reliability of 3D image display is improved, but the hardware cost is increased
Solution Approach 1:
The invention extracts and removes the black matrix component from the display structure. By eliminating this light-blocking element, the patent achieves both high brightness and correct 3D image presentation without requiring the traditional black matrix solution.
Solution Approach 2:
The phase retardation film serves multiple functions: it guides light from first pixel regions through the first phase retardation region, guides light from second pixel regions through the second phase retardation region, and simultaneously enables both 3D and 2D display modes. This multi-functionality replaces the need for separate black matrix components.
3Adaptability or versatility
If a phase retardation film with different phase retardation regions is used to enable 3D display, then the adaptability for displaying both 2D and 3D images is improved, but the brightness and viewing angle range are reduced
Solution Approach 1:
The invention applies different phase retardation properties to different regions of the phase retardation film. The first and second phase retardation regions have different retardation characteristics that are specifically tailored to guide light from different pixel types to the correct viewing direction, replacing the need for uniform black matrix blocking.
Solution Approach 2:
The invention enables dynamic switching between 2D and 3D display modes by controlling the activation state of different pixel regions. When displaying 3D images, both first and second pixel regions are activated with their respective phase retardation regions. When displaying 2D images, the system can selectively activate only the first pixel regions, dynamically adapting the display function.
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 high brightness and wide viewing angles during 2D image display while enabling 3D image presentation without reducing image quality or increasing hardware costs.
Implementation Method 1
a phase retardation film with two types of phase retardation regions is attached to a display panel such that the light provided by the pixel regions for displaying a left-eye image and the light provided by the pixel regions for displaying a right-eye image have different polarization states
Implementation Method 2
The polarizer may be disposed on an external surface of the color filter substrate, and the phase retardation film may be disposed on the polarizer
