Is LCD TV and computer screen the same? Please specify?

LCD TV can be divided into TV types. The structure of LCD TV screen is to clamp the LCD body with two special glasses, and adjust the imaging through 8-bit driving circuit and efficient backlight system. Its characteristics can also be reflected by the characteristics of ordinary LCD. Like ordinary TV, it integrates the accessories related to the receiving TV system (its function is similar to the TV card in the LCD PC host). Another feature of it is that the LCD TV produced now can also be used as a PC display.

it integrates the relevant accessories of receiving TV system (its function is similar to the TV card in the LCD PC host). It also has one feature, which is the LCD TV produced now, It can also be used as the display of a PC.

and LCD PC.
that is, the computer host + LCD display, in which the host has a TV card, so you can watch TV (even if the LCD PC does not have TV function, you can add a TV card like this, about 200 yuan).
so it seems that it is "not very cost-effective" to buy LCD TV, Because LCD PC can provide more "computer" functions.





although their terminal displays are all made of LCD panel.
this is why we think they are almost the same.
but the difference lies in them.
the performance of LCD panel used by ordinary PC is not high.
for example, the brightness is generally low About 300 lumens (if the LCD PC is less than 4000 yuan, its LCD display parameters are lower, about 200 lumens), while the LCD panel used by the general manufacturers of LCD TV is more than 400 lumens, and the slightly better ones use 500 lumens, which is basically no big difference compared with the effect of ordinary TV; Secondly, the contrast is the same. LCD TV 500:1 is common, while LCD PC 400:1

     Brightness and contrast are two hard indicators that everyone can see.
however, there are some hidden problems, which are also very important differences between them.
because the two design directions are different.
even if LCD panels with similar performance are used, their optimization circuits will be different, The most obvious thing is that LCD TV will invest a large amount of optimization scheme for imaging, and try to "use soft circuit" method to improve the clarity, because we all have the feeling that when we watch TV on 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, tiny and unclear images will cause "image blur" in the visual sense. Therefore, in order to obtain good imaging effect, we have to work hard on the imaging circuit.
for example, in view of the "residual shadow" problem of LCD, some manufacturers use some "interval" to fill in the third-party pigment to weaken the "residual shadow" phenomenon, Because every time the LCD image changes, like the image before it, it is in the "stop" state. Even if the reaction time is 12ms, it also has a "trace" of staying. Theoretically, it can't be seen by human eyes, but in the fierce war scene, However, this technology has been criticized to some extent, which also has an impact on the service life of LCD.
in addition,
in terms of image color, LCD TVs also use a variety of "filters", Its function is to optimize the TV signal, which is also applied 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.
