Soft screen or hard screen for TV? Understand this article and bid farewell to the "great injustice"

When buying TV, soft screen and hard screen are two common screen choices. LCD TV Whether IPS hard screen is better or VA soft screen is better, the network has been unable to distinguish between high and low, and some businesses will also use this as a topic to fool consumers. Today, I will give you a comprehensive science popularization about whether LCD TV is a soft screen or a hard screen, and how to distinguish between them.

First, let's understand the basic knowledge of LCD screen. Like the monitor, the LCD screen also plays an important role in TV. According to the manufacturer's public information and industry authorities, the LCD screen, that is, the LCD panel, plays a very important role in the overall cost, not the weight, but the cost. That is to say, the cost of LCD panel accounts for about 60% of the cost of a LCD TV. From this point, we can see the importance of LCD panel.

So, what are the technical characteristics of hard screen and soft screen, and which is better?

First of all, IPS hard screen and VA soft screen are two mainstream LCD display types, which are different in structure, performance and use. The question whether IPS hard screen is better or VA soft screen is better needs to be analyzed from the basic characteristics of LCD screen. So here, we still need to understand what are the technical characteristics of hard screen and soft screen, whether they are on the same running line, and whether soft screen will really be defeated by hard screen?

IPS hard screen features:

1. There is no water ripple. The liquid crystal molecules are arranged horizontally, and there is no water mark when pressing on the screen, so the image is stable.
2. Large viewing angle. IPS panel provides a wide viewing angle, with a visual angle of 178 degrees, and no color distortion.
3. It has fast response time. The response time is fast, and the ghosting and trailing phenomenon of high-speed moving pictures will not be particularly serious.
4. High contrast. At the same time, the white balance treatment can be strengthened, and the pure white effect is better.
5. Low power consumption design. Low power is relatively lower, and it is more energy-saving in use.

After introducing the features of the hard screen, let's take a look at the features of the soft screen.

VA soft screen features:

1. The color of the picture is bright. VA soft screen has high light transmittance and bright colors, and many manufacturers have adopted improved wide color gamut technology to highlight the display effect.
2. The picture details are more abundant. The VA soft screen adopts the "half pixel" display mode, which can accurately calculate the RGB three primary color distribution and imaging effect, and the image details are more expressive.
3. Fast response speed and wide viewing angle. VA soft screen liquid crystal molecules are arranged in vertical direction, and inclined angle switching, greatly improving the response speed and visual angle range.
4. Low heat and power consumption. VA soft screen has high light transmittance, so it does not need a strong backlight, so its heat dissipation is low and its power consumption is relatively small.

In fact, generally speaking, the hard screen can be understood as that a layer of hard transparent resin material is added in front of the LCD screen to protect the outer film, which does not change the basic characteristics of the LCD panel in terms of physical properties. Therefore, the quality of the screen display effect is determined by the LCD panel manufacturing process and technology, and has nothing to do with soft and hard screens. At the beginning of the development of hard screen, it was promoted by Hitachi and other Japanese manufacturers. Later, LG of South Korea improved it and formed the S-IPS hard screen technology with many selling points. At present, the main representative manufacturers of hard screens are LG and others, while the manufacturers represented by Samsung are mainly VA soft screens.

In fact, based on rational analysis, IPS hard screen and VA soft screen have their own characteristics and are aimed at different user groups. Therefore, there is no difference between a soft screen and a hard screen. Even if two products of the same model of a soft screen or a hard screen TV in the same factory batch have slight differences in picture quality.

So far, there has been no "soft" or "hard" statement among the many standards of LCD quality available at home and abroad, and no authoritative organization has ever made a comparison between hard and soft screens. Moreover, nowadays, both domestic brands and joint venture brands are relatively mature in technology. Therefore, it can be said that the hard screen and the soft screen are just different from the later processing of the LCD panel, and there is no fundamental difference between the advantages and disadvantages.

For the majority of family users, the role of LCD TV is to play TV programs, and the image quality is what consumers should pay attention to. Therefore, let's talk about the image quality of soft screen and hard screen products again. If you use the same signal source on the same occasion to watch two LCD TVs that use hard screen and soft screen respectively, if the image quality is obviously different, then the most critical problem is actually the level of LCD panel and the core configuration of the image quality chip, It should not be the difference between hard screen and soft screen that causes the difference in image quality. Therefore, it is not scientific to judge TV by soft screen and hard screen alone.
