Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional displays, such as lenticular lens and parallax barrier types, require costly and inconvenient alignment procedures, increasing manufacturing costs and reducing transmittance in two-dimensional mode, while also lacking the ability to switch between two-dimensional and three-dimensional display modes discretionarily.
Innovation Solution
A two-dimensional/three-dimensional switchable display module and device that incorporates an optical module and a revising circuit, allowing for the adjustment of light paths and relative positions between the optical module and the display panel, enabling seamless switching between 2D and 3D modes without the need for precise alignment, using a flexible optical module that can be detachably mounted and comprising a barrier plate or lenticular lens array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lenticular lens or parallax barrier is fixed on the display panel, then three dimensional display effect is achieved, but manufacturing cost increases due to specific alignment procedure
Solution Approach 1:
The optical module is made movable relative to the display panel through a movable connection structure, allowing dynamic adjustment of the optical module's position and angle. This eliminates the need for precise fixed alignment during manufacturing, reducing manufacturing costs while maintaining 3D display effectiveness.
Solution Approach 2:
The display system is divided into separate functional modules: the display panel and the optical module. The optical module can be independently adjusted and positioned relative to the display panel, allowing for easier manufacturing and assembly without requiring precise alignment between components.
2Reliability
If lenticular lens or parallax barrier is fixed on the display panel, then three dimensional display effect is achieved, but transmittance is reduced seriously in two dimension mode
Solution Approach 1:
The optical module is made movable to allow users to dynamically switch between 3D and 2D display modes. When in 2D mode, the optical module can be positioned to minimize light blocking, maximizing transmittance. When in 3D mode, the optical module is positioned to achieve the desired stereoscopic effect.
Solution Approach 2:
The optical module serves multiple functions: it can be positioned to enable 3D display effect when needed, and repositioned to minimize interference with light transmission when 2D display is required. This multi-functionality allows the system to adapt to different display modes without compromising performance in either mode.
3Reliability
If lenticular lens or parallax barrier is fixed on the display panel, then three dimensional display effect is achieved, but user cannot switch between two dimensional and three dimensional display modes discretionarily
Solution Approach 1:
The movable connection structure enables the optical module to be dynamically repositioned between different display modes. Users can discretionarily switch between 2D and 3D modes by adjusting the optical module's position, providing adaptability and versatility that fixed structures cannot achieve.

AI summary
A two dimensional/three dimensional (2D/3D) switchable display module, comprising a display panel, an optical module and a revising circuit is disclosed. The display panel has an active area. The optical module is disposed on the active area for changing a light path of a light emitting from the active area. A relative position information is between a position of the optical module and a position of the display panel. The revising circuit is used for providing a revising information based on the relative position information. The display panel receives the revising information and outputs an image corresponding to the optical module for displaying a three dimensional image.
