Is LCD TV better with a soft screen or a hard screen?

Compared with the VA screen, which is commonly known as the "soft screen", S-IPS is better in terms of image display stability. The reason is that the S-IPS hard screen has a stable and solid LCD structure, the image quality is stable, and there is no water ripple when squeezed, while the VA screen will have a large afterimage phenomenon when touched; Second, the S-IPS hard screen responds extremely fast and fast, and the moving picture is smoother, due to the motion blur effect, the VA screen will have large-scale image distortion and color changes. Third, the S-IPS hard screen has an ultra-high contrast ratio, and the pure black level is clearer.

Unlike VA screens, IPS screens have negligible white balance variation in each gray scale. At low gray scales, the unstable performance of the voltage value leads to uneven brightness.

Of course, it's a hard screen, not to mention the wide angle of view, the radiation is still small, and the picture definition is also high.

I think the hard screen is good. Its motion graphics are very responsive. Low power consumption. Low radiation.

The hard screen of LCD TV is better than the soft screen, and the main differences are in the following points:

1. Physical differences.

The molecular arrangement structure of the IPS hard screen is horizontally arranged, while the molecular arrangement structure of the VA soft screen is vertically arranged. When encountering external forces, the solidity and stability of the molecular structure of the hard screen LCD are far better than those of the soft screen. The surface of the soft screen is relatively soft, and there will be water ripples when touched lightly by hand, while the surface of the hard screen is hard, and there is basically no such phenomenon when touched by hand.

2. Service life.

The service life of the IPS hard screen is generally 70,000 hours, while the service life of the VA soft screen is 60,000 hours (both screens are theoretical design life). In terms of service life, the service life of the hard screen is 10,000 hours higher than that of the soft screen. In today's purchase, people generally choose TVs with a long service life, so the hard screen is better than the soft screen.

3. Picture quality presentation.

The hard screen is a transparent protective shell with a layer of resin material added to the LCD panel, and the soft screen is also called"VA screen", refers to the LCD panel without a protective shell, and its obvious feature is to poke the TV screen with a finger, and the image will appear obvious"Water ripples"(will disappear automatically). The main difference between a hard screen and a soft screen is whether a transparent protective case is installed, although it has little impact on the image quality of the two, but there is a difference.

4. Performance differences.

In contrast, the IPS hard screen is more protective of the screen due to the addition of a protective case, while the VA soft screen has stronger heat dissipation performance. It is worth mentioning that due to the maturity of production technology, the production technology of soft and hard screens has been perfected, and problems such as light leakage (hard screen) and color distortion (soft screen) have been solved.

LCD TV soft and hard screen selection:

1.There is no superiority or disadvantage between soft and hard screens.

Although there is a certain difference between the hard screen and the soft screen in the production process, there is no absolute superiority or inferiority in performance, and the statement that the hard screen must be better than the soft screen is wrong. The light leakage contrast of the hard screen is poor, and the color of the soft screen is distorted from the side, but the manufacturers of the hard screen and the soft screen have gradually improved their shortcomings.

2.TV production line with soft and hard screens.

The physical properties of both hard and soft screens are the same, as long as they are not impacted by gravity or carved with sharp objects, they are not easy to damage. Whether it is a hard screen or a soft screen, it is impossible to determine the quality of LCD TV products, and it should not become the only criterion for consumers to choose and choose. In fact, whether it is a soft screen or a hard screen, it will be broken and damaged when it encounters a sharp impact.

Pros & cons: Advantages of a hard screen:

The advantages are high viewing angle, fast direction and accurate color reproduction. Compared with other types of screens, the screen of the IPS screen is relatively "hard", and it is not easy to deform with water patterns when you swipe it lightly by hand, so it is also known as a hard screen.

Advantages of soft screen: good color performance, strong sense of hierarchy, and heat dissipation in place.

Disadvantages of hard screen: poor heat dissipation, easy reflection, and poor color depth of field.

Disadvantages of soft screen: distortion to touch, and unsatisfactory high-speed motion pictures.

The hard screen is relatively faster than the soft screen, but the light leakage phenomenon is more serious, the soft screen has high brightness, but it has a tail than the hard screen, there is no absolute good, if you want a better effect, buy plasma. Plasma does not sell well is not because the technology is not good, but because the technology is monopolized, and it cannot be developed, just like the Chinese character input method of the year, the Wubi input method is not the fastest, and the reason why it is popular is because there is no charge. Now Changhong has not invested more than 60 billion yuan to build a plasma screen production line?

Don't be confused by some concepts,The key is to look at the screen produced by **,If it is a comparison between Taiwan's soft screen and an imported hard screen,It must be a hard screen,If it is a comparison between Taiwan's hard screen and an imported soft screen,It must be a soft screen,Buy an LCD TV and look at the chip and backlight。 No matter how good the screen is, it only plays a display role, there is no good chip processing, it can't display a good image, the chip must be good, and you have to look at the backlight, the backlight on the market is roughly divided into two kinds, one is cold cathode, and the other is LED. The cold cathode backlight consumes a lot of power, the brightness is uneven, the color is not good, it can only reach 72% under the N standard, the service life is short, the power consumption of the LED backlight is 54% lower than the traditional cold cathode, the light is uniform, the color can reach 105% under the N standard, the service life is long, and the response speed is fast.

It is recommended that you choose an imported brand. Some domestic brands often exaggerate publicity,Some data are quite good,In fact, generally,Give two examples:1、Connect to the same signal source,1366*768Imported TV with resolution is higher than 1920*1080The definition is higher,You can try,I tried。

2. The 42-inch LCD propaganda of a domestic brand 5500 has a Blu-ray function, and the lowest price of a Blu-ray *** market is estimated to be 4999 yuan. Dare to ask how much its 42-inch LCD costs. In short, pay attention when buying, don't listen to the ** staff flickering.

It's best to take a regular *** dish and try it yourself. Which clear buys that.

Answer: LCD screen is divided into soft screen and hard screen, but this is not literal, but refers to the different arrangement of liquid crystal molecules, the liquid crystal molecules of the soft screen are perpendicular to the screen, and the liquid crystal molecular arrangement of the hard screen is parallel to the screen, so the soft screen will appear water ripples when pressed by hand, and the hard screen is not easy to appear, hence the name soft screen hard screen.

As the saying goes,Nine leaks out of ten hard screens,There is also a special leak,It is said that IPS hard screens generally have light leakage problems,The edges of the screen are at the four corners,There will be a large area of brightness exceeding the average level,Common glory wisdom screen Sony8Series and other hard screen models are common。 This is almost not the case with VA soft screens.

So a soft TV screen will be better than a hard screen.

Whether the TV screen is soft or hard is better, it doesn't really matter much.

Hard screen and soft screen are mainly different in packaging methods.

The main measure of the quality of the TV screen is to see the resolution, refresh rate, color range, viewing angle, etc.

Of course, the advantage of a hard screen is that the surface is not easy to break when it hits.

Look at the big-name brands, Sony, Samsung, Sharp, Toshiba, what screens do they use? LG's hard screen is garbage! The image quality of the soft screen is better than that of the hard screen, and the shortcomings of the soft screen trailing have long been solved by Sony's frame doubling driver technology.

The viewing angle of the soft screen has reached 178 degrees, and the viewing angle of the hard screen is large, who will sit at an angle of 180 degrees from the TV plane to watch the TV?

If you have children, it's still safe with a hard screen, and it doesn't matter if the child is older or not, the soft screen doesn't matter.

Hard screen

The biggest feature is that the two stages are on the same side (the electrodes in ordinary LCD mode are above and below); Because the electrodes are on the same side, the liquid crystal molecules are always parallel to the screen in any state, which greatly reduces the opening rate and reduces the light transmittance. It can be simply understood that a hard screen is to add a hard protective film to the LCD panel to avoid screen injury.

Disadvantages: high power consumption (relatively soft screen), light leakage.

Advantages: accurate color reproduction and high visibility.

Soft screen

Cons: Restricted viewing angles, distortion of side view.

Advantages: energy saving, large viewing angle.

1. First of all, both are liquid crystal physical structures, but the molecular arrangement is different, the hard screen LCD molecules are horizontally arranged, while the soft screen LCD molecules are vertically arranged.

2. The advantage of the hard screen is that it can protect the screen from damage to the greatest extent when the workmanship is up to standard, and there will be no water ripples when touching the screen, which is easy to clean, but the hard screen and the soft screen cannot surpass the fragile physical defects of the LCD screen - the same fear of collision.

3. Secondly, because the biggest feature of the hard screen is that its two poles are on the same surface, no matter what state it is, the liquid crystal molecules are always parallel to the screen, which will reduce the opening rate and light transmittance, so the hard screen needs more backlights when applied to LCD TVs, and to a certain extent, the power consumption is slightly larger.

4. Secondly, the hard screen has the problem of light leakage, and the black purity is not enough, so it must rely on the compensation of the optical film to achieve better black. Once the production process is not good, the outer film and the screen are not tightly pasted, which will affect the heat dissipation of the screen, and repeated thermal expansion and contraction after booting will lead to imaging distortion.

5. Of course, the hard screen also has the advantage of not erasing the old man, that is, due to the unique molecular conversion structure, the hard screen has a large viewing angle, and the response speed of the picture is relatively fast.

Hope it helps.

The screen of LCD TV is divided into hard screen and soft screen,This is the distinction in technology,There is no absolute difference between good and bad performance,There is no difference between good and bad。 Whether you think that the hard screen is good or the soft screen is good, it is incorrect,So you don't need to spend too much time on the soft and hard screen when choosing an LCD TV,You should consider the brand of the TV、After-sales service can content。

Hard screen (IPS) is relative to soft screen, and it is a concept that has been hyped by many manufacturers in recent years. IPS technology is an LCD screen technology launched by Hitachi in 2001, commonly known as "Super TFT". The so-called soft screen is that there will be "ripples" while swiping your finger across the LCD panel, and the more representative ones are Sharp ASV technology, Samsung S-PVA technology and AUO's MVA technology.

At present, there are indeed some so-called hard screens on the market, which use the method of adding harder materials such as glass or resin to the outside of the LCD screen. In fact, the real hard screen panel is the use of advanced S-IPS panel, the liquid crystal molecular arrangement of this panel is essentially different from the "soft screen", at present, only the LCD panel giant LG Electronics has hard screen technology.

The so-called soft screen and hard screen on the market do have a certain truth from the process,If you simply add glass or resin and other hard materials outside the LCD screen,The film and screen bonding process requirements are quite sophisticated,If the technology is not up to par,It is counterproductive。 The soft screen without a protective outer film, as long as consumers pay attention when using it, do not use gravity impact or sharp objects to carve, and it is generally not easy to scratch.
