1, IPS hard screen: LCD panel technology introduced by Hitachi 200 1
2.LGD IPS hard screen: refers to IPS panel, which is the LCD panel technology introduced by LG.
Second, the characteristics are different.
1, IPS hard screen: IPS hard screen LCD TV can display dynamic HD pictures excellently, which is especially suitable for the reproduction of moving pictures. It is an ideal carrier for watching digital HD pictures, especially fast moving pictures, such as competitions, racing games and action movies.
2.LGD IPS hard screen: no afterimage and no watermark when touched. The physical structure of IPS hard screen is stable, and there will be no inevitable afterimage and flicker on the ordinary screen when touching.
Third, the arrangement of liquid crystal molecules is different
1, IPS hard screen: liquid crystal molecules are oriented in opaque mode instead of light transmission mode in advance. The amount of light transmission is determined by the electrode perpendicular to the orientation direction of liquid crystal molecules. The higher the voltage, the more molecules twist, thus achieving accurate control of light.
2.LGD IPS hard screen: The molecular arrangement of IPS screen is horizontal. When subjected to external pressure, the molecular structure sinks slightly downward, but the whole molecule is still horizontal. However, the vertical arrangement of ordinary screen liquid crystals is seriously sunken, showing an inverted figure of eight.
