IPS panel has fast response speed and accurate color reproduction

The biggest feature of the IPS panel is that its two electrodes are on the same surface, unlike other liquid crystal mode electrodes, which are arranged on the upper and lower sides in a three-dimensional arrangement. Since the electrodes are on the same plane, the liquid crystal molecules are always parallel to the screen regardless of the state, which will reduce the aperture ratio and reduce the light transmittance. Therefore, the application of IPS to LCD TVs will require more backlights. In addition, there is a S-IPS panel that is an improved type of IPS

The advantages of IPS panels are high viewing angle, fast response speed, accurate color reproduction, and low price. However, the disadvantage is that the light leakage problem is more serious, and the black purity is not enough, which is slightly worse than PVA. Therefore, it is necessary to rely on the compensation of the optical film to achieve a better black. IPS panels are mainly produced by LG-Philips. Compared with other types of panels, the screen of an IPS panel is more "hard", and it is not prone to water pattern deformation with a light stroke of the hand, so it is also known as a hard screen. When you look at the screen carefully, if you see fish-scale pixels facing left, plus a hard screen, then you can be sure that it is an IPS panel.
