Small And Medium Size LCD Screen--IP Principle Of Full-view Screen Technology
Sep 12, 2018
IPS technology principle:
IPS is the abbreviation of English In-Plane Switching. The English meaning is flat conversion hard screen technology, commonly known as "hard screen". It is the most advanced liquid crystal panel technology in the world. The hard screen is a film with a resin attached to the surface. Wear the same glasses. Generally, the mainstream mobile phones will adopt the IPS screen, and the display effect is excellent, so it has become one of the major selling points of many mobile phones.
IPS (In-Plane Switching) is the most advanced LCD panel technology in the world.
Among the companies that own this technology and achieve mass production, South Korea's LG Display is the largest and the technology is at the leading position. LG Display's 7.5-generation production line has been mass-produced in January 2006 with a monthly production capacity of 150K. The cutting technology is mature and the yield is extremely high, reaching 95%.
"IPS screen technology principle"
The panel is the core of the LCD TV, and the quality of the panel determines the quality of the LCD TV by more than 60%.
Compared with other panel technologies (such as TN panel and VA panel), the IPS hard screen is special in that the liquid crystal molecules are not oriented in a transparent mode, but are oriented in an opaque mode. The electrode whose orientation direction is perpendicular determines 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 approximately proportional to the voltage, making the layer level control of the panel easier to implement.
In order to enlarge 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 that light leakage is less. In motion pictures, it performs better and achieves better contrast.
Environmental protection and power saving
IPS hard screen technology is the world's most advanced liquid crystal display technology, and is another major breakthrough in energy-saving technology. Compared with the VA soft screen, the power consumption of the IPS hard screen is further reduced, which is more energy efficient and environmentally friendly than the latter. The IPS hard screen technology creatively aligns the liquid crystal molecules horizontally, reducing the thickness of the liquid crystal layer, thereby changing the light transmittance of the liquid crystal panel. In addition, the IPS hard screen uses bipolar drive technology to increase the pixel aperture ratio by 25%. Due to the increased light transmittance, the IPS hard screen application can reduce the power of the backlight on the LCD TV, thereby achieving the effect of energy saving. At the same time, as a durable consumer goods, IPS hard-screen LCD TV theoretical life is more than 70,000 hours, beyond the soft-screen LCD TV.
Large viewing angle for the whole family
The traditional soft-screen LCD TV, when viewed from the side, will cause color drift, resulting in blurred images. Because IPS hard screen has a unique molecular level conversion structure, it can reach a viewing angle of 178 degrees from top to bottom and left and right. The color expression at any angle is not compromised, almost reaching the limit of liquid crystal display technology, basically eliminating visually. The "dead angle". At the same time, there is 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 open to the Olympics in Beijing, uses almost all LCD TVs with IPS hard-screen technology.
Accurate color, restore real picture
As a global leader in liquid crystal display technology, LG Display's IPS hard-screen technology has been favored by professionals. In the world's top LCD monitors, such as EIZO, NEC, APPLE and other professional display products, IPS is used. Hard-screen technology LCD panels to meet the demanding requirements of color in the design, printing, aerospace and other industries.
Design and printing are the most demanding industries in color, and are extremely demanding in terms of color saturation and reduction accuracy. IPS hard screen is the most accurate technology for color reproduction in current display technology. It has very high contrast and pure black level. Therefore, professionals in the design field generally believe that IPS hard-screen LCD monitors effectively reduce the design. The error between the sample and the last sample. In addition, modern medicine relies more and more on scientific testing, and the ideal black contrast effect of IPS hard screen helps to improve the speed and accuracy of diagnosis. Relatively speaking, the IPS panel has better consistency and more details, and is suitable for ultra-high grayscale fine display requirements.
"How to identify IPS hard screen"
1. Touch the LCD screen. If there is no water ripple, it can be confirmed as IPS hard screen. If water ripple occurs, it can be confirmed as soft screen.
2, can use a magnifying glass, contrast liquid crystal molecular shape map, the full pixel fish scale direction to the left is IPS hard screen.
The display of IPS LCD panel is divided into two types. The main difference is that in response time, the response time is the only place where the IPS panel is not as good as the TN panel. At present, the common IPS LCD panel has reached the standard of 5ms, basically playing games and watching movies. This demand is no different from the TN panel. The TN panel can achieve 2ms better time, but 5ms vs. 2ms in games and movies, as long as it is not required to be more demanding users, the relative price IPS is definitely It is slightly higher than the TN panel, but the difference is not big, but the angle and color are better than the TN panel. If you buy a normal IPS panel display, you can choose between 22 inches and 24 inches.
