LCD Operation in A Nutshell
The operation of TN, VA and IPS-LCDs can be summarized as follows:
- a well aligned LC configuration is deformed by an applied electric field,
- this deformation changes the orientation of the local LC optical axis with respect to the direction of light propagation through the LC layer,
- this change of orientation changes the polarization state of the light propagating through the LC layer,
- this change of the polarization state is converted into a change of intensity by dichroic absorption, usually by external dichroic polarizers.
