Solution Overview
Problem
Existing LCD display devices have a fixed and monotonous angle of view, limiting their applicability to various application scenarios and user experiences.
Innovation Solution
An LCD display device with a switchable angle of view is achieved by adjusting the electric field through two grating lines, signal lines, and pixel components, where display drivers and conductive pixel films are electrically connected, allowing for switching between narrow-angle and wide-angle modes by controlling the voltage applied to the drivers and the orientation of liquid crystal molecules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed angle of view is used in LCD display, then the device structure is simple and manufacturing is easy, but the adaptability to different application scenarios is poor
Solution Approach 1:
The patent implements a switchable angle of view by dynamically changing the electric field distribution through multiple display drivers. The liquid crystal display can switch between a first angle of view and a second angle of view by activating different combinations of display drivers, transforming a static display into a dynamic one that adapts to different viewing requirements.
Solution Approach 2:
The pixel region is divided into multiple pixel units, each with its own display driver and conductive pixel films. This segmentation allows independent control of different regions, enabling the display to present different angle of view characteristics in different areas simultaneously or to switch between different viewing modes.
2Adaptability or versatility
If multiple display drivers are added to achieve switchable angle of view, then the adaptability improves, but the device complexity increases
Solution Approach 1:
Multiple display drivers are embedded within the grating lines structure, and multiple conductive pixel films are arranged in a staggered configuration. By merging the control functionality into the existing grating line infrastructure and combining multiple pixel films in a space-efficient staggered layout, the patent reduces the overall device complexity while maintaining the switchable angle of view capability.
Solution Approach 2:
The display drivers and conductive pixel films serve multiple functions: they control the liquid crystal orientation for angle of view switching, maintain the pixel structure integrity, and enable different viewing modes. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall device complexity.
3Area of moving object
If conductive pixel films are arranged in a staggered manner, then the space utilization improves and edge electric field uniformity increases, but the manufacturing precision requirements increase
Solution Approach 1:
The conductive pixel films are arranged in an asymmetric staggered pattern rather than a symmetric aligned configuration. This asymmetric arrangement optimizes the space utilization and improves edge electric field uniformity by creating a more distributed electric field pattern, though it does require higher manufacturing precision to achieve proper alignment.
