The biggest feature of the IPS panel is that its two poles are on the same surface, unlike the other liquid crystal mode electrodes are arranged on the upper and lower sides. This technology optimizes the arrangement of liquid crystal molecules and adopts a horizontal arrangement. When the external pressure is encountered, the molecular structure is slightly depressed downward, but the overall molecules are also horizontal. When encountering external forces, the hard-wired liquid crystal molecular structure is much more robust and stable than the soft screen! Therefore, the image distortion and the color of the screen are not generated, and the screen effect can be protected to the utmost extent without being damaged. There is also an S-IPS panel that is an improved version of IPS.
IPS materialTechnically speaking, the LCD panel contains two fairly fine sodium-free glass materials called Substrates with a layer of liquid crystal in between. When the light beam passes through the liquid crystal layer, the liquid crystal itself will stand or twist in an irregular shape, thereby blocking or allowing the light beam to pass smoothly. Most liquid crystals are organic complexes composed of long rod-shaped molecules. In the natural state, the long axes of these rod-shaped molecules are substantially parallel. The liquid crystal is poured into a well-machined slotted plane, and the liquid crystal molecules are arranged along the groove, so if the grooves are very parallel, the molecules are also completely parallel. Liquid crystal is an intermediate substance between a crystalline state and a liquid state. It combines certain characteristics of liquids and crystals and exhibits some unique properties.
There is such a saying that the so-called hard screen is to add a layer of transparent resin material protective film on the surface of the LCD screen. The protective film makes the hard screen have a certain rigidity, and it is lightly rubbed with fingers, and there is no obvious shadow or other water ripple phenomenon on the panel.
In fact, the reason why the hard screen is hard (ie, touching the waterless pattern) is not to attach a resin protective film on the outside of the liquid crystal screen, but is determined by the molecular structure of the liquid crystal screen. The hard-screen technology innovatively adopts a horizontally arranged liquid crystal molecular structure, and when subjected to external pressure, the molecular recovery speed of the hard screen is 10 times faster than that of the vertically aligned molecules. Therefore, it can be kept as it is when touched. Not only that, when shaking and bumping, the hard-screen LCD will not have the problem of jitter and residual image, and the display effect will not change.
The structure of the hard screen and the soft screen are different, and the hard screen liquid crystal molecules are horizontally arranged, so that water ripple does not occur when pressed. The image is more stable, the color is real, and the viewing angle is wide. The soft screen liquid crystal molecules are vertically arranged, so water ripple will occur when pressed.
The advantages of IPS hard screen in terms of dynamic resolution, accurate color reproduction, and viewing angle. First of all, compared with the traditional soft-screen liquid crystal, the IPS hard-screen has a stable liquid crystal molecular arrangement structure, and the response speed is faster, so that it has superior expressiveness in dynamic definition. The hard screen also completely eliminates the blurring and water-grain diffusion phenomenon of the soft-screen LCD screen when it is subjected to external pressure and shaking. When the speed-speed picture is played, the image sticking and smearing are eliminated, so that the moment is in motion. The aerospace, automotive, and subway industries have adopted IPS hard screens to achieve image quality without loss. It is reported that the newly opened Beijing Metro Line 5 and bus car TVs have adopted IPS hard-screen LCD.
The reason for achieving the above significant advantages is that IPS (ln-Plane Switching) technology innovatively uses a horizontal rotating molecular arrangement, so the molecular reduction power is stronger than that of the vertically aligned soft-screen liquid crystal technology, and the liquid crystal panel is also More stable and sturdy. Not only that, IPS hard screen technology also makes the viewing angle of the top, bottom, left and right greatly extended, close to 180 degrees, can see the quality of the image without any discount in any side angle, for multi-angle observation and display for aerospace, medical, etc. The field is a rare tool.
In fact, not only in the professional field, but also in the field of home appliances closely related to consumer life, IPS hard-screen LCD is widely used due to its unique advantages. Influenced by experts, mass consumers are increasingly inclined to IPS hard screen when purchasing LCD TVs.
We know that buying LCD TVs requires buying HD. But the vast majority of HDTVs promoted in the market refer to the clarity of still pictures. And when we watch TV and play games, most of the time we watch dynamic pictures. However, some of the previous soft-screen LCDs have a flaw in displaying the dynamic picture effect, and residual images and smear appear. This has also been criticized by consumers. Therefore, to satisfy the consumers, the response time of the LCD TV is required to be short, and the smear and afterimage of the dynamic display are effectively controlled. And this is the strength of IPS hard screen.
What are the advantages of IPS compared to ordinary screens?Compared with the ordinary TN screen, IPS has several outstanding advantages mainly in the perspective and providing richer color performance, and the color scale performance will be excellent.
To put it simply, the conventional LCD technology used in the past has two obvious problems. One is that the viewing angle is small, and the color is severely discolored from the side; the other is that the dynamic image smear delay is obvious.
The IPS (In-Plane Switching) technology solves these two problems. The LCD wide viewing angle technology developed by E Li in 1996, and the LG Display company in South Korea has the largest scale and the leading position in technology. Compared with the traditional liquid crystal, the IPS hard screen has a stable liquid crystal molecular arrangement structure, and the response speed is faster, so that it has superior expressiveness in dynamic definition. The hard screen also completely eliminates the blurring and water-grain diffusion phenomenon of the traditional liquid crystal display when it is subjected to external pressure and shaking, and the image sticking and smearing are eliminated when playing the extreme speed picture. Therefore, the moment is in the state of motion. The aerospace, automotive, and subway industries have adopted IPS hard screens to achieve image quality without loss.
Of course, with the gradual maturity of production technology, IPS hard screen is no longer a high-end product at a high level. At present, IPS screen has been widely used in civilian fields such as high-definition LCD TVs, high-definition large-screen mobile phones, and so on. hope it helps you
quick response
The IPS hard screen technology changes the arrangement of liquid crystal molecular particles, and adopts horizontal conversion technology to make the reaction speed of the liquid crystal screen faster and more stable. When dealing with continuous dynamic pictures, one of the great advantages of horizontal conversion is to speed up the deflection speed of liquid crystal molecules, which is reflected in the fast response speed of IPS hard screen, which makes the motion track of the image more delicate and clear, and solves the problem. The problem of image smearing and jitter.
When consumers enjoy high-speed motion pictures for a long time, the IPS hard screen can ensure clear, smooth and real effects, and the eye irritation is significantly reduced, which is in full compliance with health appeals.
Large viewing angle
The IPS hard screen panel has a viewing angle of 178 degrees. The degree of color change produced when viewed from the front and viewed from different angles is called the color distortion rate. The results show that the value obtained by the IPS hard screen is almost indistinguishable from the naked eye, which 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 IPS hard-screen color fidelity features. The excellent color reversal and brightness conversion of the IPS hard screen allows you to enjoy the vivid, saturated and natural ideal picture from any angle.
Excellent picture
IPS hard-screen LCD TVs are excellent for dynamic HD images, especially for moving image reproduction, without image sticking and smearing. They are ideal for watching digital HD images, especially fast moving images such as games, racing games and action movies. Carrier.
Due to the unique horizontal molecular structure of the IPS hard screen, it is very stable when it is touchless, and it is very stable, so it is very suitable for TV and public display devices with touch function.
Touch waterless
Through the understanding of the advantages of IPS screen, we can think of it. It is estimated that Jobs saw the IPS screen adopting hard screen technology, which is suitable as a touch screen; when the angle of view is wide, when many people watch movies or play gravity sensing games such as racing cars, The advantages are obvious; and the response speed is fast, the color reproduction is true, and so on, the IPS is selected as the display screen of the product.
Environmental protection and power saving
IPS hard screen technology is another major breakthrough in energy-saving technology. IPS hard screen power consumption is further reduced, more energy efficient and more environmentally friendly. 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.
Accurate color
IPS hard-screen technology is favored by professionals 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 has a very high contrast ratio, and the black level is clearer. Therefore, professionals in the design field generally believe that the IPS hard-screen liquid crystal display 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 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.
Size advantage
In terms of the size of the LCD screen, IPS also has an obvious advantage over the old LCD screen. For example, the 42-inch and 40-inch panels on the market, the 42-inch LCD TV with hard-screen technology is 67.58 square inches larger than the 40-inch area of ​​the old LCD screen. This is not just a 2-inch literal difference, but a whole More than a laptop. The 42-inch screen can display the full picture of the digital TV, so consumers can enjoy the larger picture. The 40-inch screen is slightly inferior, and the small part of the corner is still not displayed, and the restored picture is defective.
