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,
In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds . If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance.
Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology like IPS. Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades ...
