IPS technology principle:
IPS is the abbreviation of In-Plane Switching in English. The English meaning is in-plane switching hard screen technology, commonly known as "hard screen". It is the most advanced LCD panel technology in the world. Like wearing glasses. Generally, more mainstream mobile phones will use IPS screens, which have excellent display effects, so it has become one of the major selling points of many mobile phones.
IPS (In-Plane Switching) hard screen technology is currently the most advanced LCD panel technology in the world.
Among the companies that own this technology and realize mass production, South Korea's LG Display is the largest company with a leading technical level. The 7.5-generation production line of LG Display has achieved mass production in January 2006, with a monthly production capacity of 150K; the cutting technology is mature, and the yield rate is extremely high, reaching 95%.
"IPS screen technology principle"
Panel is the core of LCD TV, and the quality of panel determines more than 60% of the quality of LCD TV.
Compared with other panel technologies (such as TN panel and VA panel), the special feature of IPS hard screen is that it does not pre-orient the liquid crystal molecules into a light-transmitting mode, but orients them into an opaque mode. The electrodes with the orientation direction of the molecules perpendicular to each other determine that the higher the voltage, the more molecules are twisted, thus achieving precise control of the light. It only controls one deflection angle of the IPS liquid crystal panel, and the number of deflection molecules can be close to the direct ratio of the voltage, so that the level control of the panel is easier to realize.
In order to expand the viewing angle, the basic module of the liquid crystal molecules is V-shaped, and the liquid crystal molecules are perpendicular to the panel, and the light is easily controlled inside the panel, so there is less light leakage. In motion, it performs better and achieves better contrast.
Environmental protection and energy saving
IPS hard screen technology is the most advanced liquid crystal display technology in the world, and it is also another major breakthrough in energy-saving technology. Compared with the VA soft screen, the power consumption of the IPS hard screen is further reduced, and it is more energy-saving and more environmentally friendly than the latter. IPS hard screen technology creatively arranges the liquid crystal molecules horizontally, reduces the thickness of the liquid crystal layer, and thus changes the light transmittance of the liquid crystal screen. In addition, the IPS hard screen adopts bipolar drive technology, which increases the pixel aperture ratio by 25%. Due to the increased light transmittance, the application of IPS hard screen on LCD TV can reduce the power of backlight, so as to achieve the effect of energy saving and power saving. At the same time, as durable consumer goods, IPS hard-screen LCD TVs have a theoretical service life of more than 70,000 hours, exceeding soft-screen LCD TVs.
Large viewing angle, suitable for the whole family to share
Traditional soft-screen LCD TVs, when viewed from the side, will experience color shifting, resulting in blurred images. Since the IPS hard screen has a unique molecular horizontal conversion structure, the viewing angle of 178 degrees can be achieved up and down, left and right, and the color expressiveness of any angle is not compromised, almost reaching the limit of liquid crystal display technology, basically eliminating visual problems. The "dead corner". At the same time, there will be no color drift like a soft screen, and a clear picture can be seen from the side. It is understood that the Metro Line 5, which is currently in operation in Beijing to welcome the Olympic Games, uses almost all LCD TVs with IPS hard-screen technology.
Accurate color restores the real picture
As a global leader in liquid crystal display technology, LG Display's IPS hard screen technology is unanimously favored by professionals. On the world's top liquid crystal displays, such as EIZO, NEC, APPLE and other professional display products, all use IPS LCD panel with hard screen technology to meet the strict color requirements of professionals in design, printing, aerospace and other industries.
Design and printing are the industries that have the most demanding requirements on color, and have extremely high requirements on color saturation and reproduction accuracy. IPS hard screen is currently the most accurate technology for color reproduction in display technology. It has a very high contrast, and the pure black level is clearer. Therefore, professionals in the design field generally believe that IPS hard screen LCD effectively reduces the design. The error from the final sample produced. In addition, modern medicine is increasingly dependent on scientific testing, and the ideal black contrast effect of IPS hard screen is helpful to improve the speed and accuracy of diagnosis. Relatively speaking, the IPS panel has better consistency and more details, which is suitable for ultra-high grayscale and fine display requirements.
"How to identify IPS hard screen"
1. Lightly touch the LCD screen, if there is no watermark, it can be confirmed as an IPS hard screen; if there is a watermark, it can be confirmed as a soft screen.
2. You can use a magnifying glass to compare the shape of liquid crystal molecules. If the fish scales of all pixels face to the left, it is an IPS hard screen.
There are two types of IPS LCD panel monitors. The main difference is in the response time. The response time is the only place where the IPS panel is not as good as the TN panel. At present, the ordinary IPS LCD panel has reached the 5ms standard, basically playing games and watching movies. This demand is no different from that of TN panels. TN panels can better achieve 2ms, but 5ms is compared to 2ms in games and movies. As long as users are not demanding, it will not affect much. In terms of relative price, IPS must be It is slightly higher than the TN panel, but the difference is not big, and it is better than the TN panel in terms of angle and color. For home use, you can buy an ordinary IPS panel display. It is recommended to choose between 22 inches and 24 inches.
