POLARIZER AND ARRAY, POLARIZATION-CONTROLLABLE METHOD AND APPARATUS, AND ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18167142 titled 'POLARIZER AND ARRAY, POLARIZATION-CONTROLLABLE METHOD AND APPARATUS, AND ELECTRONIC DEVICE

Simplified Explanation

The patent application describes a polarizer that includes multiple types of polarization units, each consisting of two liquid crystal cells laminated together. The liquid crystal cells have alignment films connected to electrode layers that can apply an external voltage to the liquid crystal layer. The first and second liquid crystal cells of each polarization unit can be controlled separately as "connected" or "disconnected", and the alignment films of the first liquid crystal cells have different orientations between the multiple types of polarization units. When one liquid crystal cell is in an on state, the emergent light of the polarization unit is polarized light in one direction.

  • The polarizer includes multiple types of polarization units, each consisting of two liquid crystal cells laminated together.
  • The liquid crystal cells have alignment films connected to electrode layers that can apply an external voltage to the liquid crystal layer.
  • The first and second liquid crystal cells of each polarization unit can be controlled separately as "connected" or "disconnected".
  • The alignment films of the first liquid crystal cells have different orientations between the multiple types of polarization units.
  • When one liquid crystal cell is in an on state, the emergent light of the polarization unit is polarized light in one direction.

Potential Applications

  • Display devices such as LCD screens
  • Optical filters
  • Polarization control in optical systems

Problems Solved

  • Provides a method for controlling the polarization of light using liquid crystal cells
  • Allows for separate control of different polarization units
  • Offers flexibility in adjusting the orientation of alignment films

Benefits

  • Enhanced control over the polarization of light
  • Improved performance of display devices and optical systems
  • Increased versatility in designing and implementing polarization-controllable systems.


Original Abstract Submitted

A polarizer, a polarizer array, a polarization-controllable method and apparatus, and an electronic device are disclosed. The polarizer includes multiple types of polarization units, each polarization unit includes a first liquid crystal cell and a second liquid crystal cell that are laminated, each liquid crystal cell includes a liquid crystal layer and an alignment film, and the alignment film is connected to an electrode layer configured to apply an external voltage to the liquid crystal layer. The first liquid crystal cell and the second liquid crystal cell of each polarization unit may be separately controlled as “connected” or “disconnected”, and orientations of alignment films of first liquid crystal cells between all the multiple types of polarization units are different. In a same polarization unit, when one liquid crystal cell is in an on state, emergent light of the polarization unit is polarized light in one polarization direction.
