Switching (plane conversion) technology is a LCD panel technology introduced by Hitachi on 200 1, commonly known as "super"
Tft. The ips camp headed by Hitachi has gathered a number of manufacturers such as lg- Philips, Hanyu Caijing, idtech (a joint venture between Chi Mei Electronics and ibm in Japan), but there are not many models that can be seen in the market. The biggest feature of ips panel is that its two poles are on the same plane, unlike other liquid crystal mode electrodes which are arranged vertically. Because the electrodes are on the same plane, liquid crystal molecules are parallel to the screen in any state, which will reduce the aperture ratio and light transmittance, so ips is applied to lcd.
Television needs more backlight. There is also an s-ips panel, which belongs to the improved ips.
The advantages of ips panel are high viewing angle, fast response, accurate color reproduction and low price. However, the disadvantage is that the light leakage problem is serious, and the purity of black is not enough, which is slightly worse than pva. It is necessary to rely on the compensation of optical film to achieve better black. At present, ips panels are mainly produced by lg- Philips. Compared with other types of panels, the screen of ips panel is more "hard", and it is not easy to be deformed by water lines when swiping by hand, so it is also called hard screen. When you look at the screen carefully, if you see a fish-scale pixel to the left, plus a hard screen, then you can be sure that it is an ips panel.
