Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD devices require manual adjustment of viewing angles, which is not user-friendly and inefficient, especially when multiple adjustments are needed, and existing automatic solutions are either costly or complex due to the use of cameras and image recognition algorithms.
Innovation Solution
An automatic angle-adjustable display device with wireless sensors and an angle adjustment mechanism that calculates the viewer's position by emitting and receiving wireless signals, allowing the screen to automatically adjust its viewing angle to maintain optimal orientation without distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rotation and tuning of the LCD device is performed, then the viewing angle can be adjusted to eliminate image distortion, but the operation becomes complex and time-consuming
Solution Approach 1:
The system uses wireless sensors to automatically detect viewer position and calculates optimal viewing angles, then autonomously adjusts the screen orientation without requiring manual user input or interaction
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated system using wireless sensing technology and electronic control to detect viewer position and adjust screen angle automatically
2Extent of automation
If camera-based image recognition is used to detect viewer position, then automatic angle adjustment can be achieved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent uses inexpensive wireless transmitting and receiving sensors instead of expensive camera systems, making the automatic adjustment feature more cost-effective and accessible
Solution Approach 2:
The patent extracts only the essential function of viewer position detection from complex camera-based image recognition systems, using simpler wireless signal transmission and reception to achieve the same goal

AI summary
An automatic angle-adjustable display device and an angle-adjustable method are provided. The automatic angle-adjustable display device includes a screen, three wireless transmitting and receiving sensors, an angle adjustment mechanism and a control unit. The wireless transmitting and receiving sensors are respectively disposed at first, second and third positions of the screen. In response to a control signal issued from the control unit, the angle adjustment mechanism is driven to adjust the viewing angle of the screen with respect to the viewer. The angle-adjustable method includes steps of triggering the wireless transmitting and receiving sensors to emit these wireless signals, measuring first, second and third distances between the first, second and third positions of the screen and the viewer according to the reflected wireless signals, and adjusting the viewing angle of the screen with respect to the viewer according to these distance differences.
