What is the difference between ips touch screen and capacitive touch screen ?

Capacitive touch screen is the name of design for the touch screen. In fact, IPS is not a material, on the contrary, It is a technical name. Its essence is super TFT. In another word, IPS screen is also a kind of TFT screen.

But which one is better ? without a doubt, the screen using IPS technology is much better. The IPS screen alters the arrangement of TFT liquid crystal molecules (the liquid crystal molecules of ordinary TFTs are arranged horizontally, and the liquid crystal molecules of IPS are vertically arranged), so that it can deliver you a larger viewing angle, and the water ripple( also known as the hard screen) is not apparently to be observed when pressed.

Besides, IPS technology also features preferable color reproduction and high verisimilitude.
