IPS (In-Plane Switching) technology is a liquid crystal panel technology introduced by Hitachi in 2001, commonly known as "Super TFT."
What is the meaning of the IPS screen? The advantages of the IPS screen are high viewing angle, fast response, and accurate color reproduction. It is a high-end product in the LCD panel. And compared to the PVA panel, the LCD TV with IPS screen can achieve 780 lines of dynamic resolution. In terms of static definition, HD can still be achieved according to the 720-line HD standard. The panel technology enhances the dynamic display effect of the LCD TV, and can obtain better picture quality when watching sports programs such as sports events and action movies. Compared with other types of panels, the IPS panel is not easy to appear water-like deformation by hand, so it has a hard screen. When you look at the screen carefully, if you see a fish-scale pixel with a direction to the left, plus a hard screen, you can be sure that it is an IPS screen.
In general, the IPS screen is a screen that uses IPS technology. Compared with the normal display screen, it has a clearer and more detailed dynamic display effect, and the visual effect is more outstanding. Therefore, when we select the LCD display or the smartphone screen, The IPS screen will perform even better. Because of this, the general IPS screen LCD monitor or smart phone will become a big selling point often mentioned by merchants.
IPS screen advantagesAs the most advanced LCD panel technology, many flagship mobile phones or some brands of LCD monitors today use IPS screens, such as Samsung Note4, iPhone6 ​​and other well-known models, all using the top IPS panel screen. What are the advantages of the IPS screen? Listed below.
Large viewing angle
The viewing angle of the IPS screen panel can reach 178 degrees, and the degree of color change produced when viewed from the front and at different angles becomes the color distortion rate, and the obtained value is almost indistinguishable from the naked eye. It means that the effect of viewing the picture from the front or the side is the same.
True color
This is also a comprehensive display of the characteristics of the IPS screen color pillow. Due to the color flip and brightness conversion of the IPS screen, you can see the high-quality pictures with vivid colors and saturated naturalness from any angle.
Excellent dynamic quality
The IPS screen screen can display dynamic high-definition images, especially suitable for moving image reproduction, without image sticking and smearing. It is a good carrier for watching digital high-definition video and fast moving pictures, such as games and competition game box action movies.
Energy saving and environmental protection
The IPS screen technology also has a major breakthrough in the end of nuclear power, and the power consumption of the IPS screen is further reduced, which is more energy-saving and environmentally friendly. Moreover, since the liquid crystal molecules are arranged more reasonably, the thickness of the liquid crystal layer is reduced, thereby changing the transmittance of the liquid crystal panel, enhancing the display effect, and also making the display panel thinner and more power-saving.
Accurate color
IPS screen technology is favored by professionals to meet the more demanding requirements of color in the design, printing, aerospace and other industries.
IPS screen shortcomingsThere are advantages and disadvantages, and what are the disadvantages of the iPS screen?
Since the IPS screen adopts the arrangement of the horizontal liquid crystal molecules, the viewing angle is increased while the penetration of the light is reduced. In order to better display the bright color, the illuminance of the backlight is increased, so the light leakage phenomenon is extremely common in the IPS screen. As the screen increases, the problem of large-area edge leakage has been a criticism of IPS.
Because the IPS screen can't improve the penetration and improve the backlight, it also loses its high contrast competitive advantage. The static contrast ratio of the general IPS is between 2000:1 and 3000:1. The static contrast of the AV screen can easily reach 5000:1, so the contrast is not high, which is also a disadvantage.
How to choose the PS screen?Not all IPS screens are the best, IPS screen panels are also good or bad, there are four main types, namely AH-IPS, E-IPS, S-IPS, H-IPS, P-IPS.
In the field of displays, the most commonly used display for thousands of dollars is the worst E-IPS, which is the casted IPS panel, and the color is slightly better than TN. AH-IPS is a new concept nowadays. It can be equated with the worst E-IPS. Basically, according to many official statements, AH-IPS is slightly better than E-IPS, but it is almost the same.
To put it simply, we can understand this, P-IPS "H-IPS" S-IPS "E-IPS," and H-IPS is a relatively high-priced product, and the performance of S-IPS is very good. Not bad, the price is relatively moderate, it is recommended to choose.
