Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display apparatus uses only a two-dimensional display mode, then the structure is simple and manufacturing cost is low, but the display functions are limited
Solution Approach 1:
The light-transmitting module is designed to perform multiple functions: in the first state it allows light to pass through for 2D display, and in the second state it forms lens and grating layers for 3D display. This multi-functionality enables a single component to replace what would traditionally require separate 2D and 3D display systems, thereby enriching display functions while controlling structural complexity
Solution Approach 2:
The light-transmitting module employs electrically controlled material layers that can dynamically change their light-transmitting state based on applied voltages. By switching between different voltage states, the module transitions between 2D and 3D display modes, enabling the display apparatus to adapt its functionality in real-time without physical reconfiguration
2Adaptability or versatility
If separate 2D and 3D display systems are used, then display functions are comprehensive, but manufacturing cost increases
Solution Approach 1:
The patent merges the 2D and 3D display capabilities into a single integrated system. The light-transmitting module combines the functions of what would traditionally be separate 2D display and 3D optical elements (lens layers and grating layers) into one component that can switch between modes, thereby reducing manufacturing costs while maintaining comprehensive display functions
Solution Approach 2:
The light-transmitting module serves as a universal component that can operate in both 2D and 3D display modes. By designing this single module to perform multiple functions, the patent eliminates the need for separate 2D and 3D display systems, reducing overall manufacturing cost while maintaining display function versatility
3Adaptability or versatility
If a light-transmitting module forms lens and grating layers for 3D display, then naked-eye three-dimensional image display is enabled, but the light-transmitting state changes from the first state
Solution Approach 1:
The light-transmitting state of the module is controlled by changing electrical parameters (voltage) applied to the electrically controlled material layers. By adjusting voltage levels, the module transitions between the first light-transmitting state (for 2D display) and the second light-transmitting state (for 3D display with lens and grating layers), enabling mode switching through simple parameter changes rather than complex mechanical adjustments

Function Achieved in This Case
Enables the display apparatus to enrich its functions by displaying both two-dimensional and naked-eye three-dimensional images, improving display capabilities and reducing manufacturing costs through shared substrates and optimized lens and grating layer configurations.
Implementation Method 1
a lens layer and a grating layer that are arranged in a direction close to or away from the display module are formed on the light-transmitting module
Implementation Method 2
a lens layer and a grating layer that are arranged in a direction close to or away from the display module are formed on the light-transmitting module

AI summary
A display control method and an apparatus are provided. The display apparatus includes a controller, a display module, and a light-transmitting module. The controller is configured to: in a two-dimensional display mode, control the display module to display a first two-dimensional image, and control the light-transmitting module to be in a first light-transmitting state, so that the display apparatus displays the first two-dimensional image; and in a three-dimensional display mode, control the display module to display a second two-dimensional image, and control the light-transmitting module to be in a second light-transmitting state, so that the display apparatus displays a naked-eye three-dimensional image. The first light-transmitting state is different from the second light-transmitting state; and in the second light-transmitting state, a lens layer and a grating layer are formed on the light-transmitting module.
