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.

The difference between LCD and night crystal TV

many people think that LCD TV and LCD display are no different.
in fact, they are not.
.
.
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, However, when playing computer games, there will be slow image movement and "tailing" of high-speed images.
in contrast.
LCD TV will not have similar phenomenon.
generally.
TV signals are composed of sound, sound and video 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 have to work hard on imaging processing.
.
.
the reason why LCD TV can eliminate the phenomenon of dullness is that the LCD TV adopts a powerful and larger capacity digital processing circuit.
for example, Toshiba TV's newly launched "digital new brain" LCD chip recently 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,It not only reduces the sound noise, but also restores the original image.
.
.
people who like to watch movies on DVD may have encountered such a problem.
the DVD system is different from the TV system, and sometimes produces chroma data noise.
Toshiba has been prepared for this, The whole process digital tracking noise reduction technology of DVD can remove the noise and spots produced in the compression process of the format image of DVD disc, improve the image clarity of DVD movie, and correct the color information that cannot be corrected in DVD player, so that the color information can be restored more accurately, Improve the picture quality of DVD movies.
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.
.
due to the inherent limitations of the early LCD.
there are visual angle, response time, brightness and contrast 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 more than 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 the display screen as high as 800:1.
and now the LCD TV on the market usually measures the brightness of the whole picture 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 rectangular diagram to detect the light and shade distribution, and then uses the powerful optimization mode to adjust the light and shade level of each picture to solve the defect of residual shadow.
then uses the oblique direction correction technology of digital animation to correct each pixel of the picture.
to change the defect of impure black scale, Let the color plump.
If an LCD TV has the application of these technologies.
to watch sports events, It's 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 more and more big.
in the competition of color TV industry,
price is not 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 Reasons.
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 screen for LCD TV, There will be endless debates about which technology can represent the development of LCD TV in the future.

LCD TV can be connected to a computer as a display.
LCD TV can be connected to a computer as a display
the display accuracy of LCD TV is not as good as that of LCD TV.
.
LCD TV can be used as LCD TV
