Imaging processing and color
computer enthusiasts all know that although LCD has the advantages of high brightness and no radiation compared with flat panel display, when playing computer games, it will appear the phenomenon of slow image movement and "tailing" of high-speed images.
in contrast.

What's the difference between LCD TV and ordinary LCD?

LCD TV will not appear similar phenomenon.
generally.
TV signal is composed of sound, color and color 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 dullness phenomenon is that 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 has been changed, and YC separation circuit and color decoding circuit have been integrated into a large-scale integrated circuit for all digital signal transmission and processing, which not only reduces the sound noise, but also truly restores the original appearance of the image.

people who like to watch movies on DVD may have encountered such problems.
the standard of DVD is different from that of TV, Sometimes, chroma data noise will be produced.
in this paper, the color data noise is analyzedToshiba has long been prepared for this.
the whole process digital tracking noise reduction technology of DVD can remove the noise and spots generated 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, To 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 uses various "filters", which are used to optimize the TV signal, which is also used in ordinary TV.
all these are generally not used in ordinary LCD, This is a big difference between the imaging effect of LCD PC and LCD TV.

brightness and contrast
due to the inherent limitations of early LCD displays, there are three major obstacles, namely, visual angle, response time and manufacturing cost.
in fact, among the technical performance indicators of LCD TV, the biggest impact on consumers' visual experience is brightness, contrast, color Resolution and viewing angle, and 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 generally used in LCD TV is more than 400 lumens, and some good ones, such as Toshiba TV, can reach 500 lumens; Secondly, the contrast is also 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.
this paper introduces the principle of dynamic optimization system technologySometimes there will be a shadow, when the impact of Huai Jun, the impact of the North China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China Sea, the South China τ I'm very happy to meet you. I'm very happy to meet you. I'm very happy to meet you. I'm very happy to meet you У Wang You's surname is Wu Ji τ It's hard to choose between the two? Br/> 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 bigger and bigger.
and 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.
with the breakthrough of LCD technology barriers one by one.
technological progress will make the increasingly mature LCD technology radiate greater vitality, health and competitiveness The advantages of environmental protection make large screen LCD TV another choice.
I believe that one day people will not mistake LCD TV for LCD TV, The resolution of LCD TV screen is usually 1366x768 or 1920x1080.
LCD TV only supports 640x480 / 60Hz, 800x600 / 60Hz and 1024x768 / 60Hz; Ordinary computer LCD is usually 1024x7681440x900 and so on, with a variety of display formats and refresh rate the brightness of computer LCD is less than 300nit
3) The response time of LCD TV screen is less than 8 ms; However, the response time of computer LCD is longer.

4) the image quality is different.
using LCD TV as computer display.
the signal will be processed by contrast, chroma and noise reduction; However, the computer LCD will not do these processes.
