IPS technical principle:
IPS is the abbreviation of in plane switching in English, which means plane conversion hard screen technology, commonly known as "hard screen". It is the most advanced LCD panel technology in the world. Hard screen is a film with a layer of resin attached to the surface, just like people wearing glasses. Generally, mainstream mobile phones will use IPS screen with excellent display effect, so it has also become one of the major selling points of many mobile phones.
IPS (in plane switching) hard screen technology is the most advanced LCD panel technology in the world.
Among the companies with this technology and mass production, LG display company in South Korea is the largest and the technical level is in a leading position. LG display's generation 7.5 production line has achieved mass production in January 2006, with a monthly capacity of 150k; The cutting technology is mature and the yield is very high, reaching 95%.
"Technical principle of IPS screen"
Panel is the core of LCD TV. 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 orient the liquid crystal molecules into the light transmission mode in advance, but into the non light transmission mode. 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 components will be twisted, so as to realize the accurate control of light. It only controls one deflection angle of IPS liquid crystal panel Degree, and the number of deflection molecules can be close to positive proportion to the voltage, so that the hierarchical control of the panel is easier to realize.
In order to expand the viewing angle, the basic module of liquid crystal molecules is V-shaped, and the liquid crystal molecules are perpendicular to the panel, so the light is easy to be controlled inside the panel, so the light leakage is less. In the moving picture, it can perform better and achieve better contrast.
Environmental protection and power saving
IPS hard screen technology is the most advanced LCD technology in the world, and it is also another major breakthrough in energy-saving technology. Compared with VA soft screen, the power consumption of IPS hard screen is further reduced, which is more energy-saving and environmental friendly than the latter. IPS hard screen technology creatively arranges liquid crystal molecules horizontally, reduces the thickness of liquid crystal layer, and changes the light transmittance of liquid crystal screen. In addition, the IPS hard screen adopts bipolar driving technology to increase the pixel opening rate by 25%. Due to the increased light transmittance, the application of IPS hard screen in 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 a durable consumer goods, the theoretical service life of IPS hard screen LCD TV is more than 70000 hours, which exceeds that of soft screen LCD TV.
Large viewing angle, suitable for family sharing

Traditional soft screen LCD TV, when viewed from the side, will have color drift, resulting in blurred picture. Because the IPS hard screen has a unique molecular level conversion structure, it can reach a visual angle of 178 degrees up, down, left and right. The color expressiveness of any angle is not discounted, which almost reaches the limit of liquid crystal display technology and basically eliminates the visual "dead corner". At the same time, there will be no color drift like the soft screen, and a clear picture can be seen from the side. It is understood that at present, the subway line 5 opened in Beijing to welcome the Olympic Games adopts almost all LCD TVs with IPS hard screen technology.
Color accurately restore the real picture
As a leading manufacturer in the field of global LCD technology, LG display's IPS hard screen technology is unanimously favored by professionals. On the world's top LCD products, such as Eizo, NEC, apple and other professional display products, the LCD panel with IPS hard screen technology is used in one color to meet the stringent requirements of professionals in design, printing, aerospace and other industries for color.
Design and printing are the industries with the most stringent requirements for color, and they require very high color saturation and restoration accuracy. IPS hard screen is the most accurate technology for color restoration in the current display technology, with very high contrast and clearer pure black level. Therefore, professionals in the design field generally believe that iPS hard screen LCD effectively reduces the error between the design and the final sample. In addition, modern medicine relies more and more 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, IPS panel has better consistency and more details, which is suitable for ultra-high gray and fine display requirements.
"How to identify IPS hard screen"
1. Touch the LCD screen gently. If there is no water mark, it can be confirmed as IPS hard screen; If water marks appear, it can be confirmed as soft screen.
2. You can use a magnifying glass to compare the liquid crystal molecular shape diagram. The IPS hard screen is when the full pixel fish scale direction is to the left.
There are two kinds of displays for IPS LCD panel. The main difference is that the response time is the only place where IPS panel is inferior to TN panel. At present, ordinary IPS LCD panels have reached the standard of 5ms. Basically, the demand for playing games and watching movies is no different from TN panel. TN panel can reach 2ms, However, 5ms vs. 2ms has little impact on games and movies as long as it is not for demanding users. In terms of relative price, IPS is certainly a little higher than TN panel, but the gap is small. However, it is better than TN panel in terms of angle and color. For home use, it is OK to buy an ordinary IPS panel display. It is recommended to choose between 22 inches and 24 inches.
