Dynamic Visual Angle Adjustment Panel for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile display devices face challenges in adjusting visual angles to accommodate both private viewing and sharing requirements, as anti-peeping films are cumbersome and damage the screen when repeatedly applied and removed.
Innovation Solution
A display device with a visual angle adjustment panel, comprising alternating transmissive and opaque regions controlled by a control device, allowing users to switch between large and small visual angles by receiving specific instructions, thereby enabling seamless transitions between normal and anti-peeping display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an anti-peeping film is mounted on the display device to reduce the visual angle, then privacy protection is improved, but the device complexity and ease of operation deteriorate due to repeated film application and removal
Solution Approach 1:
The patent applies the dynamics principle by making the visual angle adjustment panel switchable between different states. The panel can dynamically change its light-shielding properties based on control signals, allowing automatic transition between privacy protection mode and normal display mode without manual film application or removal. This resolves the contradiction by eliminating the need for repeated manual operations while maintaining privacy protection when needed.
2Adaptability or versatility
If an anti-peeping film is repeatedly torn down and pasted to meet different visual angle requirements, then adaptability is improved, but the screen damage and user experience deteriorate
Solution Approach 1:
The visual angle adjustment panel is designed as a dynamic component that can switch between different light-shielding states through control signals. This eliminates the need to repeatedly apply and remove physical films, thereby preventing screen damage from adhesive residue while maintaining the ability to adapt between privacy protection and normal display modes.
Solution Approach 2:
The patent replaces the mechanical system of physically applying and removing anti-peeping films with an electronic control system. The control device sends instructions to the visual angle adjustment panel, which automatically adjusts its light-shielding properties through electrical signals, eliminating mechanical contact and adhesive-related screen damage while preserving adaptability.
3Reliability
If the visual angle is reduced using light-shielding strips, then privacy protection is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent merges the visual angle adjustment panel with the display device structure, integrating the light-shielding functionality into the existing display system. The panel is positioned at the edge of the display and controlled by the device's existing control mechanisms, thereby achieving privacy protection without adding significant structural complexity or requiring separate independent components.
