Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices can only perform one function, such as three-dimensional display or anti-peep display, and lack the ability to switch between multiple functions like two-dimensional plane, three-dimensional stereoscopic, and anti-peep displays simultaneously.
Innovation Solution
A display system comprising at least two layers of liquid crystal cells on a light-emitting side of the display device, with a controller device to control the positions and widths of light-transmitting and light-shielding regions in each layer, allowing for switching between various display modes by adjusting electrical signals applied to the liquid crystal cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device is designed to perform a single function (three-dimensional display or anti-peep display), then the device structure can be simplified and manufactured easily, but the device lacks versatility and cannot switch between multiple display modes
Solution Approach 1:
The display device segments the liquid crystal display into multiple independent layers (at least two layers), where each layer can be independently controlled to form light-transmitting regions and light-shielding regions. This segmentation allows each layer to contribute differently to the overall display mode, enabling versatile functionality while maintaining manageable complexity through modular design
Solution Approach 2:
The patent implements multi-functionality by designing the liquid crystal display system to perform multiple display modes (two-dimensional plane display, three-dimensional stereoscopic display, and anti-peep display) using the same physical structure. The controller device switches between modes by adjusting the electrical signals applied to different liquid crystal layers, allowing one device to serve multiple purposes without requiring separate hardware for each function
2Adaptability or versatility
If multiple layers of liquid crystal cells are added to enable multi-functionality, then the display system can switch between different display modes, but the device complexity and structural difficulty increase
Solution Approach 1:
By dividing the display into multiple separable liquid crystal layers with independent electrode structures, the patent makes the complex multi-layer system manufacturable through standardized modular assembly processes. Each layer can be manufactured and tested independently before being assembled into the final multi-layer configuration
Solution Approach 2:
The patent combines multiple liquid crystal layers with identical or similar structures into a single integrated display system. The layers are arranged in sequence along the light path and controlled by a unified controller device, allowing the system to achieve multi-functionality through the combination of simple, repeatable structural units rather than through complex individual components

Function Achieved in This Case
Enables the display system to seamlessly switch between multiple display modes, including two-dimensional plane, three-dimensional stereoscopic, and anti-peep displays, catering to diverse application requirements by controlling the exit angle and arrangement of light regions.
Implementation Method 1
the driving electrode is configured to be applied with an electrical signal to control the liquid crystal layer corresponding to the driving electrode to switch between a light-transmitting state and an opaque state
Implementation Method 2
the liquid crystal layer is a polymer liquid crystal layer including a black dye; the polymer liquid crystal layer including the black dye is in the light-transmitting state in a situation of being applied without an electric field, and is in the opaque state in a situation of being applied with an electric field
