Dynamic Light Path Structure for Full Screen Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display designs face challenges in achieving a full screen display due to non-display regions, such as those occupied by light receiving modules, which hinder the utilization of these areas for image information display.
Innovation Solution
A display device with a second display region and a light path structure that switches between states to either allow light to pass through to the light receiving module or reflect light to the light transmissive region, enabling the light transmissive region to display image information and thus achieving full screen display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light receiving module is placed under the non-display region to collect external light, then the light receiving function is achieved, but the non-display region cannot be used for image information display and full screen display is difficult to realize
Solution Approach 1:
The patent applies the dynamics principle by making the light path structure movable between two positions. When the light path structure is in the first position, it allows light to pass through to the light receiving module. When moved to the second position, it blocks the light path and allows the light transmissive region to display image information. This dynamic reconfiguration enables the system to adapt between light receiving and display functions, effectively resolving the contradiction between maintaining light receiving capability and maximizing display area.
Solution Approach 2:
The patent introduces a temporal dimension by switching between different operational states. The light path structure alternates between transmitting light to the sensor and blocking to enable display, effectively adding a time-based dimension to the spatial arrangement. This allows the same physical space to serve dual purposes at different times, resolving the area conflict.
2Area of stationary object
If the light transmissive region is used for image display to achieve full screen display, then the screen share ratio is improved, but the light receiving module cannot receive external light through the opening
Solution Approach 1:
The light path structure is designed to be dynamically adjustable between two states: a first state where it transmits light to the light receiving module, and a second state where it blocks the light path to enable image display in the light transmissive region. This dynamic switching mechanism allows the system to alternate between light receiving and display functions, ensuring that maximizing display area does not permanently sacrifice light receiving capability.
3Adaptability or versatility
If a conventional design with non-display region is used, then the light receiving module can be placed there, but the screen share ratio is reduced and large black frame is required
Solution Approach 1:
The light transmissive region is designed to serve dual functions: it can transmit light to the light receiving module when needed, and it can display image information when the light path is blocked. This multi-functionality eliminates the need for a separate non-display region, allowing the entire screen area to be utilized for display purposes while maintaining light receiving capability through temporal switching.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a high screen share ratio by effectively utilizing the light transmissive region for image display, eliminating the need for a large black frame and enhancing the overall visual effect of the full screen display.
Implementation Method 1
a semi-reflective and semi-transparent structure and a reflective structure are configured on a path of the light path structure, and a reflective surface of the reflective structure faces toward the semi-reflective and semi-transparent structure; the semi-reflective and semi-transparent structure comprises a light transmissive surface and a reflective surface configured opposite to each other; when the second display region is in the second state, the reflective surface is flipped by 180 degrees with respect to a position of the light receiving module in the first state, and faces the light transmissive region and the second display region; the reflective surface reflects the light emitted from the second display region to the light transmissive region
Implementation Method 2
when the second display region is in the first state, the light transmissive surface of the semi-reflective and semi-transparent structure faces the light transmissive region, and the reflective surface of the semi-reflective and semi-transparent structure and the reflective structure function together, and the light passing through the light transmissive surface reaches the light receiving module
