Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current naked-eye 3D display products are limited to front-side viewing and suffer from interference from strong ambient light, which affects the display effect due to the transmission of light through the transflective plate.
Innovation Solution
A display device comprising two display panels and an intermediate panel that can switch between transparent, non-transparent, and transflective states, allowing for enhanced 3D image stereo effect and reduced ambient light interference, with the intermediate panel being an electrochromic or liquid crystal panel that adjusts its state via an electric field to control light transmission and reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transflective plate is used in the display device, then the display can be viewed from the front side with good contrast, but ambient light transmits through the plate and interferes with the displayed images
Solution Approach 1:
The intermediate panel is designed to dynamically change its light transmission properties between transparent and non-transparent states based on ambient light conditions. This dynamic adjustment allows the system to adapt to different lighting environments, blocking ambient light when necessary while maintaining display visibility.
Solution Approach 2:
The patent changes the optical parameters of the intermediate panel by switching between transparent and non-transparent states. This parameter change allows the panel to control light transmission characteristics, thereby reducing ambient light interference while maintaining front-side viewing capability.
2Object-affected harmful factors
If the intermediate panel is set to non-transparent state to block ambient light, then ambient light interference is reduced, but the 3D image stereo effect is diminished
Solution Approach 1:
The system dynamically switches the intermediate panel between transparent and non-transparent states based on real-time ambient light detection. When ambient light is low, the panel remains transparent to preserve 3D stereo effect. When ambient light is high, the panel switches to non-transparent state to block interference, thus adapting optimally to different lighting conditions.
Solution Approach 2:
The display device incorporates ambient light detection capability and uses this feedback to automatically adjust the intermediate panel's transparency state. This closed-loop control ensures the panel is in the optimal state for current lighting conditions, balancing ambient light rejection with 3D image quality.
3Device complexity
If the display device is designed for front-side viewing only, then the structure is simple, but the viewing angle is limited and user versatility is reduced
Solution Approach 1:
The intermediate panel serves multiple functions: it acts as a beam splitter for front-side 3D display, a light blocking element for ambient light rejection, and enables dual-sided viewing capability. This multi-functionality allows a single component to address multiple requirements without significantly increasing overall system complexity.
Solution Approach 2:
The display device dynamically adjusts its viewing mode by changing the intermediate panel's transparency state. In transparent state, it enables dual-sided viewing for collaborative scenarios. In non-transparent state, it provides optimized front-side viewing with ambient light blocking, thus adapting to different usage scenarios.

AI summary
A display device, an operating method thereof, and a display system are provided. The display device includes a first display panel (100), a second display panel (200) and an intermediate panel (300); wherein the intermediate panel (300) has a transparent state and a non-transparent state, the intermediate panel (300) includes a first side (303) and a second side (304) which are disposed opposite to each other, and a first surface (301) and a second surface (302), which are transflective and disposed opposite to each other, the first display panel (100) is connected to the first side (303) of the intermediate panel (300) and the second display panel (200) is connected to the second side (304) of the intermediate panel (300). When the intermediate panel is in the transparent state, the two display panels cooperate with each other, so as to enhance the 3D effect and suspension effect of a display image of the display device. When the intermediate panel (300) is in the non-transparent state, the two display panels can be independently controlled and the influence of ambient light and the like on the display device can be reduced.
