Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with multiple display screens are limited to arranging them on different surfaces or areas, lacking the ability to display multiple contents simultaneously on the same display window, which restricts achieving various display effects.
Innovation Solution
A display module with at least two layers of display screens, where one display unit has a higher transmittance than a specific transmittance, allowing the second display unit's light to transmit through, enabling both to display different contents in the same window, along with sensing units to detect operations and adjust display information accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display screens are arranged on different surfaces or areas, then the display function is provided, but the display effects are limited and cannot achieve multiple contents simultaneously on the same window
Solution Approach 1:
The patent transitions from arranging display screens in horizontal planes (different surfaces or areas) to stacking them vertically in the depth dimension. Multiple display screens are positioned at different depths along the light transmission direction, enabling multiple contents to be displayed simultaneously on the same window surface through optical layering, thus achieving enhanced display effects without increasing spatial footprint.
Solution Approach 2:
The patent implements a nested structure where multiple display screens are stacked one behind another along the light transmission direction. The first display screen is positioned closer to the viewer, while the second display screen is positioned behind it, creating a layered nested arrangement that allows both displays to be visible through the same window area, thereby achieving multiple display effects.
2Adaptability or versatility
If display screens are stacked with different transmittances, then multiple contents can be displayed in the same window, but the light transmission and visibility may be affected
Solution Approach 1:
The patent applies different transmittance properties to different display screens based on their specific functions and positions. The first display screen has a first transmittance optimized for its position closer to the viewer, while the second display screen has a second transmittance optimized for its position behind the first screen. This localized optimization of transmittance ensures that each screen performs its display function effectively while maintaining overall system performance.
Solution Approach 2:
The patent changes the transmittance parameter of different display screens to achieve optimal light transmission and display quality. By carefully selecting and adjusting the transmittance values of the first and second display screens, the system enables multiple contents to be displayed simultaneously while maintaining adequate light transmission and visibility for the viewer.
3Ease of operation
If sensing units are added to detect operations, then touch-sensitive functionality is maintained, but the device complexity increases
Solution Approach 1:
The patent designs the sensing units to serve multiple functions: they detect touch operations on the first display screen, and through the optical transmission properties of the stacked structure, enable detection of operations on the second display screen as well. This universal sensing capability allows a single sensing unit configuration to provide touch-sensitive functionality for multiple display screens, reducing the need for separate sensing units for each screen.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables multiple display effects by allowing different contents to be displayed on stacked display units in varying frequencies, brightness, and contrast, while maintaining touch-sensitive functionality, even with a single sensing component, allowing responsive operations based on user interactions.
Implementation Method 1
the first display unit has a first transmittance, and the first transmittance is higher than a specific transmittance; a first light reflected by the second display unit or a second light generated by the second display unit is able to transmit through the first display unit

AI summary
The present invention provides a display module, an electronic device and a display control method. The display module may comprise: a first display unit disposed in a first area, configured to display first image information, wherein the first display unit has a first transmittance, and the first transmittance is higher than a specific transmittance; a second display unit disposed in a second area, configured to display second image information, wherein a first light reflected by the second display unit or a second light generated by the second display unit is able to transmit through the first display unit. By using the display module, a user can see the second image information presented by the second display unit while watching the first image information presented by the first display unit. A different display effect may be presented by combining the first display unit and the second display unit.
