LCD TV is very different from LCD display. Many people think that there is no difference between LCD TV and LCD monitor, but it is not.
LCD TV and LCD display are very different.
many people think that LCD TV and LCD display are no different.
in fact, they are not.

The difference between LCD TV and LCD

imaging processing and color computer enthusiasts all know.
although LCD display has the advantages of high brightness and no radiation compared with flat panel display, it will appear the phenomenon of slow image movement when playing computer games In contrast, LCD TV will not appear similar phenomenon.
generally.
TV signal is composed of sound, sound and sound Brightness and color composition.
these three groups of numbers are processed inside the TV.
we can enjoy the realistic picture and sound.
even if we use LCD panels with similar performance.
there will be differences in their signal optimization. The most obvious thing is that LCD TV will invest a large amount of optimization scheme in imaging, because everyone has this feeling, When we watch TV on the LCD, because the area is small, we have to watch it at a distance of less than one meter or even less than half a meter. In that case, the image is tiny and unclear, which will cause "image blur" in the visual sense. Therefore, we need to obtain good imaging effect, We still have to work hard on imaging processing.
the reason why LCD TV can eliminate the dullness phenomenon is that the LCD TV adopts powerful and larger capacity digital processing circuit.
for example, Toshiba TV's newly launched "digital new brain" LCD chip recently.
it continues Toshiba's all digital advanced processing technology, The original TV signal processing mode is changed, and YC separation circuit and color decoding circuit are integrated into a full digital signal transmission and processing large-scale integrated circuit, which not only reduces the sound noise, but also truly restores the original appearance of the imagePeople who like to watch movies on DVD may have encountered such a problem.
the DVD system is different from the TV system, sometimes it will produce chroma data noise.
Toshiba has been prepared for this for a long time.
digital tracking noise reduction technology can remove the noise and spots produced in the compression process of DVD format image, and improve the image clarity of DVD movie, At the same time, it can correct the color information that cannot be corrected in the DVD player, so as to restore the color information more accurately and improve the image quality of the DVD movie.
at the same time, the three-dimensional dynamic surround sound can make the sound range wider.
in addition,
in terms of image color, LCD TV also adopts various "filters", whose function is to optimize the TV signal, This is also used in ordinary TV.
all of these are generally not used in ordinary LCD, which is a big difference between the imaging effect of LCD PC and LCD TV.
brightness and contrast of early LCD due to inherent limitations.
there are visual angle, response time, image quality, etc In fact, among the technical performance indicators of LCD TV, the most important ones that affect consumers' visual perception are brightness, contrast, resolution and viewing angle, The brightness is an important index to evaluate the image quality of LCD TV.
the brightness of ordinary LCD panel is generally about 300 lumens.
the LCD panel used in LCD TV is generally above 400 lumens, and the better ones, such as Toshiba TV, can reach 500 lumens; Secondly, the contrast is the same. LCD TV 500:1 is a common thing, while LCD PC is only about 400:1.
nowadays.
Toshiba's dynamic optimization system technology can make the contrast of display screen as high as 800:1.
Toshiba's dynamic optimization system technology can make the contrast of display screen as high as 800:1In addition, the LCD TV on the market usually measures the brightness of the whole picture averagely in the process of processing pictures.
sometimes there are residual shadows, impure black scale, and poor color saturation. Toshiba's digital new brain technology reanalyzes the picture with a square diagram to detect the light and dark distribution, Then, the strong optimization mode is used to adjust the light and shade level of each picture to solve the defect of residual shadow.
then, the oblique direction correction technology of digital animation is used to correct each pixel of the picture.
the defect of impure black scale is changed to make the color full.
If an LCD TV has the application of these technologies.
it is used to watch sports events, It is a very good choice.
with the continuous emergence of new flat-panel TV technology and the continuous expansion of LCD TV screen.
the difference between LCD TV and LCD will be greater and greater.
in the competition of color TV industry,
price is no longer the main means of competition.
according to Toshiba's prediction.
technological breakthrough will be another important reason for the price reduction in the future market.
in the future, the price of LCD TV is not the main means of competition With the breakthrough of LCD technology barriers one by one.
the progress of technology makes the increasingly mature LCD technology radiate greater vitality. The advantages of health and environmental protection make large screen LCD TV another choice for people.
I believe that one day.
people will no longer mistake LCD for LCD TV, There will be endless debates about which technology can represent the development of LCD TV in the future.
