The difference between soft and hard IPS screen screen
IPS technology (In-Plane Switching, flat conversions) is a Hitachi LCD screen technology, launched in 2001, commonly known as "Super TFT." IPS camp led by Hitachi together, LGD, HannStar Caijing and other manufacturers.
Greatest characteristics of this technology are its poles are on the same side, and unlike other models of LCD electrode is in the upper and lower sides, stereo arrangement. Electrodes on the same plane, no matter what state the liquid crystal molecules are always parallel to the screen, it will reduce the aperture ratio, reduced the rate of transmission, so IPS applications will require more light in the LCD TV, and to a certain extent, power consumption is also bigger.
Another drawback is more serious problem of Leaky, black pure enough, less contrast than PVA, must therefore rely on optical film's compensation in order to achieve a better black.
Advantage is the high viewing angle IPS screen, access to fast, accurate color. Compared with other types of screen, IPS screen screen is "hard", gently draw pattern deformation is not prone to water, it is also a hard screen said.
