How to distinguish IPS hard screen, soft screen and glass screen?

Distinguish between hard and soft screens.

The traditional LCD screen is a "soft screen", and as long as you touch it, there will be blur and water ripple diffusion, which will affect the picture quality. The LCD panel with the "hard screen" process can reduce the pressure interference from the outside world and effectively protect the screen. Therefore, the "hard screen" is more durable than the "soft screen" and also has more advantages in the cleaning of the display.

In the store,The panels of LCD TVs look similar,How to distinguish whether it is a hard screen or a soft screen? In fact, the method is very simple, just use your finger to gently slide on the LCD screen, if there are obvious water marks in the place where your finger slides, it is a "soft screen". On the contrary, if there are no water marks, or the water marks are not obvious, then it proves that this is a "hard screen" panel.

Detects whether the screen is trailing.

Compared with plasma, the picture tailing phenomenon is a major disadvantage of LCD TVs. When buying an LCD TV, you should choose one with less tailing. You can look at the TV screen from multiple angles, such as choosing the angle to face the screen, then offset some angles, and stand at the same level as the TV screen to see if you can see the image.

Identify dead pixels and bright spots.

When buying, you should also identify whether the LCD TV has dead points and bright spots. The easiest way to do this is to make the screen completely black and see if there are any bright spots in the pure black. Then make the screen completely white and see if there are any black dots.

Finally, change to red, green, and blue to check the integrity of the color dots. If you find that there are too many dead pixels during the inspection, do not buy them.

Fingers touch the screen, and if there is no water streak, it can be confirmed that it is a hard screen, and the glass screen will be reflective, but the hard screen does not!

To put it simply, it is a look at two models and three certifications. The so-called look is to look at the molecular arrangement structure of the LCD TV screen, and the real IPS hard screen is arranged with a greater than number; The second touch is to touch the soft and hard of the screen, if you touch it with your hand, there are obvious water lines, it is a soft screen, and if the water lines are not obvious, it is a hard screen; Three certification is to let the shopping mall guide write on the invoice whether it is a hard screen, if it is a real IPS hard screen, he dares to write, if it is not her, then dare not write, the best verification of the glass is not the glass.

IPS screen advantages.

The dynamic picture is clear and super stable.

IPS screen technology is currently the world's most advanced liquid crystal technology. Compared with the traditional screen LCD, the hard-screen LCD with IPS screen technology responds faster and presents a smoother moving picture. It has the following advantages:

1. Dynamic picture, no afterimage of the image.

IPS hard screen.

2. Dynamic picture, uniform response speed.

IPS hard screen.

3. Dynamic picture, no color offset.

In order to detect the dynamic clarity of the hard screen,In the authoritative test"Dynamic image response time"Gray scale comparison,In60Hz picture,IPSThe dynamic response speed of the LCD screen is faster than that of the ordinary screen LCD,IPSThe LCD TV shows a balanced scatter in each gray scale"Dynamic response time。 When reaching the top speed of 120Hz, the dynamic response speed of the hard screen is still faster than that of the soft screen, that is to say, in the **rapid picture, the IPS screen can still perform the dynamic picture effect well.

Wide viewing angles. Traditional soft-screen LCD TVs, when from the side**, will have color drift, resulting in blurred pictures. As the IPS hard screen has a unique score.

The sub-horizontal conversion structure, therefore, the viewing angle can reach 178 degrees up and down, and the color expression of any angle is not discounted, almost reaching the limit of liquid crystal display technology, basically eliminating the visual "dead angle". At the same time, there will be no color drift like a soft screen, and a clear picture can also be seen from the side of the auspicious digging surface.

Solid screen. There is no afterimage and no water ripple when touched, and the physical structure of the IPS hard screen is stable, and there will be no inevitable afterimage and flickering on the ordinary screen when touched. The molecular arrangement of the IPS hard screen is horizontal, so the molecular structure sinks slightly downward when touched, but the overall molecule is still horizontal, and the ordinary screen with the vertical arrangement of the molecules is seriously subsident when touched, and the structure is unstable, after touching the screen, the IPS hard screen has about 10 times faster recovery speed than the ordinary screen soft screen.

Professional color. IPS hard screen is comparable to the color grading ability of color experts, which can truly present images, and is widely used in professional fields such as TV stations, and is highly sought after by professionals.

Universal screen. With the development of liquid crystal products, various LCD products currently appear on the market, such as TVs, monitors, mobile phones, etc., which use IPS hard screen panels, and the color effect can reach the same field.

Size advantage. Due to the difference between IPS screen and VA screen in the panel cutting process, generally speaking, the specifications of IPS screen in the mainstream size are 42 inches and 47 inches, while the VA screen is cut with 40 inch and 46 inch specifications, the diagonal length of the 42-inch IPS screen is, and the diagonal length of the 40-inch VA screen is, the 42-inch IPS screen is 12% larger than the 40-inch VA screen. It's roughly the size of a 12-inch laptop screen.

IPS is a more professional display, which is worth considering.

At present, the viewing angle of soft-screen LCD TVs on the market can only reach about 170 degrees, while IPS hard screen technology improves the horizontal and vertical viewing angles of LCD TVs to 178 degrees, almost reaching the level of flat right-angle TVs. Therefore, the limitations of the effective display area of the soft-screen LCD TV can only be suitable in the middle**,IPS hard screen technology LCD will not be distorted even on the side**picture。

In addition,Through careful observation, it will be found that intuitivelyIPSThe clarity of hard-screen LCD TV is significantly better than that of soft screen。 IPS hard screen technology LCD TV in the first moving picture, the image is smooth and clear, more stable than the traditional soft screen. The expert explains it this way:

IPS hard screen technology can react faster when displaying dynamic images, which can effectively reduce motion blur and restore colors realistically. Due to the limitations of liquid crystal molecules, the soft screen cannot better improve the grayscale response time compared with IPS, and the image distortion is easy to occur when the moving picture is expressed. This is also the reason why many consumers give priority to IPS hard screen technology LCD TVs.

Personally, I think it's more practical to buy a hard screen monitor, and what my cousin bought is the IPS hard screen monitor you said. The screen of this monitor is very sturdy, and there will be no water streaks when pressed with your fingers, and the picture is very stable, which I think is very practical for such a monitor. Recommended for you, you can learn about this kind of display when you have time, this monitor is very popular now!

IPS screen: It is the LCD surface spike technology launched by Hitachi in 2001.

Principle: The liquid crystal molecule is oriented in advance to become a light-transmitting mode, but the orientation becomes an opaque mode, the amount of light transmission is determined by the electrode perpendicular to the direction of the liquid crystal molecule orientation, the higher the voltage, the more molecules are torsioned, so as to achieve accurate leakage guessing control of light.

The differences between IPS hard screen and VA soft screen are:

1. Touch the LCD screen, if there is no water ripple, it is an IPS hard screen; If there is a water streak, it can be confirmed that it is a VA soft screen.

2. Use a magnifying glass to compare the shape of the liquid crystal molecule, and the all-pixel fish scale direction is facing left, which is the IPS hard screen.

3. The power consumption of the IPS hard screen is lower than that of the VA soft screen.
