Yes, the building owner is right. The LCD TV with good picture quality has little irritation to the eyes. It can relieve eyesight fatigue. I watched a LCD TV that day, and I felt that compared with other TV pictures, it was quite excellent. It is a LED backlight LCD TV with IPS hard screen panel. The hard screen panel seems to be high-end technology to achieve perfect picture quality.

What kind of LCD TV is good?

I watched an LCD TV that day.
I feel that compared with other TV pictures, it is still excellent.
it is an LED backlight LCD TV with IPS hard panel.
the hard panel seems to be high-end technology, To achieve the perfect picture quality.

to choose LCD TV depends on your own needs.
it mainly depends on the size, screen and brand of TV to choose your own TV.
the size is mainly determined according to the viewing distance (that is, the distance from sofa to TV: 1.7m-25 inches.
2m-32 inches, 2.4m-37 inches, 2.5m-40 inches, 2.7m-42 inches, 3m-46-47 inches, 3.3m-52 inches, 3.5m-55 inch (37 Inch is the lowest cost performance, 40 inch can be considered) screen: (soft and hard screen)     Hard screen is a popular concept in recent years. From the technical point of view, there is no substantive breakthrough, but it is still used by sales promotion staff to "attract" consumers.
in this paper, we introduce the concept of hard screen   The so-called hard screen.
is a product that adds a layer of transparent resin material with high hardness to protect the outer film on the LCD screen.
this process was initially promoted by Hitachi and other Japanese manufacturers.
later, LG greatly improved it, and formed a unique S-IPS hard screen technology.
at present.
the main representative manufacturers of hard screen are LG Philips, LG, Toshiba, LG The LCD TVs of Hitachi and other manufacturers mostly use hard screens.
TN, PVA, MVA and other panels belong to soft screens.
the main representative manufacturers are Samsung and sharp.
the hard screen only adds a layer of protective film on the LCD panel.
the LCD TVs of Hitachi and other manufacturers mainly use hard screensIt can't change the basic physical properties of the LCD panel.
in the same situation.
using the same signal source to watch two different LCD TVs, if the picture quality is obviously different, the key problem should be the level of the LCD panel and the performance of the core driver, not the software and hardware of the screen.
therefore.
the reasonable explanation of the hard screen and the soft screen only depends on the production process characteristics of the manufacturer, In fact, the hard screen and the soft screen are equally fragile, so they are afraid to touch sharp objects and can't bear the impact of gravity.
.
in the case of screen material   Although the hard screen has a layer of protective film.
it seems that the safety of the hard screen is slightly higher than that of the soft screen, the process requirements of the hard screen are very high. If the light transmission performance of the protective film is not good enough, the color effect of the screen will be directly affected.
if the control of the pasting process of the outer film of the screen is not strict enough.
if the technical specifications are not met, the imaging distortion may be caused in use, However,
the physical properties of hard screen and soft screen are the same, as long as there is no gravity impact or sharp objects, they are not easy to be damaged.
experts in the home appliance industry believe that.
both hard screen and soft screen have the same physical properties, It is impossible to determine the quality of LCD TV products, and it should not be the only standard for consumers to choose and choose  .
  So.
although there are some differences between hard screen and soft screen in manufacturing process, there is no difference in performance.
the former has high wear resistance but easy reflection.
the latter has low wear resistance but no reflection.
the theory of good hard screen and poor soft screen is completely falseBrand: it's not convenient to talk more about brand.
If LZ budget is enough, choose joint venture, if budget is not enough, choose domestic.
PS: some LCD TVs have a frequency doubling technology.
this technology can effectively solve the problem of LCD tailing, So frequency doubling technology is also a very important technical index.
