Some LCD TVs of the two big brands, Sony and Samsung, use Taiwan's garbage screen. Taiwan screen is very fragile and pretentious. We should take care of them carefully. Sometimes we can't watch sports games. Now IPS hard screen LCD TV is very popular.
Some styles of LCD TVs of Sony and Samsung have adopted Taiwan's garbage screens.

From the Internet often see LCD TV Taiwan screen is rubbish, are cheating!

Taiwan's screens are very fragile.
be careful.
sometimes watching sports games is delayed.
now IPS hard screen LCD TVs are very popular.
there are also some good quality!! 1
experts suggest buying LCD TV and choosing hard screen panel. Relevant experts from China Consumer Association point out that when buying flat-panel TV, we must consider the display screen, core components, operation mode and other important indicators comprehensively to choose a TV with high cost performance.
for LCD TV, LCD panel is the most critical component, accounting for more than 2 / 3 of the total cost, Consumers should pay enough attention to this. Manufacturers have their own words for hard screen and soft screen, which makes consumers confused.
some people point out that the difference between hard screen and soft screen only lies in whether a layer of high hardness external screen is added to the LCD screen. The hard screen will affect the image quality under the condition of thermal expansion and cold contraction, and the light transmission performance is not good, It will also affect the color effect of the screen.
the soft screen is very delicate.
it is easy to be scratched, and so on.
these statements are not scientific and accurate.
to choose a good LCD TV.
a good LCD panel, we must first understand the scientific principle, relevant parameters and current mainstream technology of LCD panel.
the key technology of LCD panel: 1 The wide viewing angle is small.
when viewing from a larger angle, the picture will lose color, and the contrast and color performance are very poor. This kind of LCD TV is not suitable for home use, so the major manufacturers are constantly improving the wide viewing angle technology.
at present, LG's iPS technology uses the two-way tilt of liquid crystal molecules to greatly shorten the response time.
changing the orientation of liquid crystal molecules makes the viewing angle wider.
this paper introduces the development of LG's iPS technologyAlthough these technologies mainly focus on improving the visual angle.
the reduction of response time, the performance of color and the improvement of contrast are also included in these technologies.
2 One of the disadvantages of the early LCD panel with fast response is that the response time is too long.
this will cause the phenomenon of dragging shadow on the screen when playing moving pictures, which was a problem that seriously hindered the development of LCD TV in the past. However, with the development of LCD display technology, the response time becomes shorter and shorter, and the current mainstream LCD panel has reached 8 ms.
3 LCD panel aspect ratio consumers buy LCD TVs for higher picture quality on the one hand.
on the other hand, it is also to meet the needs of playing high-definition digital TVs in the future.
at present, the aspect ratio of most LCD TVs in the market is 16:9.
it should be noted that some LCD TVs use screens from earlier production lines, The screen ratio is not 16:9, but 15:9, and the physical resolution of this kind of LCD TV is 1280x768.
the screen ratio is not much different from 16:9 to 15:9.
however, the future digital TV signal will use 16:9 signal, and the picture of this kind of LCD TV will be flattened or cut off when playing digital TV, Consumers should also be careful.
hard screen is more secure when they buy it.
only the IPS hard screen produced by LG is 42 inch, while the panels of other panel suppliers are generally 40 inch screens of earlier production lines, which need further improvement.
in terms of image display stability.
hard screen performs better. When the S-IPS hard screen is squeezed or touched normally, its screen display will not be affected, Because a protective layer with thermal conductivity is added on the front surface of the display screen, the light transmission performance and heat dissipation performance of the display screen are improved,At the same time, it also ensures the stability of the image quality display.
the viewing angle of the screen.
the hard screen has a slight advantage.
although the viewing angle of the mainstream LCD panel on the market now has reached 170 degrees.
the experiment shows that the S-IPS hard screen developed by LG can reach 178 degrees super wide viewing angle up and down / left and right, which can truly reproduce the wonderful picture from any angle, It further solves the problem that the viewing angle range is relatively small and the picture is slightly distorted when viewed from the side.
