Anti-peeping Backlight Divergence Angle Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-peeping display devices lack the ability to switch between normal and anti-peeping modes according to user needs, as they only operate in a fixed anti-peeping mode.
Innovation Solution
A display device with an anti-peeping backlight module and a regulator that adjusts the divergence angle of the backlight to switch between normal and anti-peeping modes, allowing the display to operate in either divergent or anti-peeping light states based on user requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed anti-peeping mode is used with polarizers on the display device and glasses, then privacy protection is achieved for operators wearing glasses, but the display mode cannot be switched according to user needs
Solution Approach 1:
The patent applies the dynamics principle by making the anti-peeping function switchable between ON and OFF states through a regulator that controls the backlight module. This allows the display device to dynamically adjust its operating mode based on user needs, transforming a static anti-peeping implementation into a dynamic system that can adapt between different display modes while maintaining reliable anti-peeping protection when activated.
2Ease of operation
If the regulator increases the divergence angle of backlight to obtain divergent light, then normal display mode is achieved, but anti-peeping protection is lost
Solution Approach 1:
The regulator dynamically adjusts the divergence angle of the backlight, switching between a first divergence angle for normal display mode and a second divergence angle for anti-peeping mode. This dynamic control allows the system to alternate between providing broad display visibility and implementing focused anti-peeping protection, resolving the contradiction between normal accessibility and privacy protection.
Solution Approach 2:
The patent changes the divergence angle parameter of the backlight to switch between operating modes. By adjusting this optical parameter, the system transitions between normal display mode (first divergence angle) and anti-peeping mode (second divergence angle), enabling the display to adapt its light distribution characteristics based on operational requirements.
3Object-affected harmful factors
If the regulator maintains the divergence angle of backlight to obtain anti-peeping light, then privacy protection is achieved, but normal display mode is lost
Solution Approach 1:
The system uses dynamic switching of the regulator to alternate between maintaining a second divergence angle for anti-peeping protection and a first divergence angle for normal display. This allows the display device to provide peeping prevention when needed while restoring full display accessibility when the anti-peeping function is deactivated.
