for consumers,
it is not as easy and casual as ordinary furniture after all when they buy LCD TVs, I hope consumers can take this opportunity to buy genuine products.
.
.
1. Pay attention to whether the display size is complete.
.
at present, the mainstream sizes of LCD TVs are basically 27 inches, 32 inches and 37 inches.
these have been able to meet the viewing needs of living rooms and bedrooms, but here we should remind that it is better to buy brands with rich product lines, The reason is very simple. The products of these brands basically adopt the "sixth generation" LCD panel production line, and only the products off the production line can the LCD screen really meet the requirements of HDTV.
this paper introduces the development of HDTV in ChinaAt present.
the product sizes of mainstream brands mostly include 42, 37, 32, 27 inches and other specifications.
.
.
2. See clearly the resolution size.
.
resolution is a very important indicator of LCD TV.
but we should not blindly think that the larger the resolution, the better. LCD TV generally has the best resolution, also known as the maximum resolution, LCD TV can show the best image.
at present, the resolution of LCD TV is mainly 800 × 600、1024 × 768、1366 × 768、1920 × 1080.
the author suggests that the current purchase of LCD TV should be at least 1024 × 768, which can meet the minimum requirements of HD video.
at present.
the resolution of mainstream brands on the market has reached this level, and the resolution of sharp, Sony and TCL's main models is even higher.
.
.
3 Observe the response time carefully.
.
response time (reflection time) is another very important technical parameter of LCD TV.
due to the limitation of imaging principle, the display response time of LCD TV is too long, which is easy to appear dynamic residual image in the image. For example, when watching football match, if the response time is not good, the image will be dragged, At present, for LCD TV, the response time of 16ms can meet the visual requirements of the naked eye, and there is no problem in appreciating TV programs.
of course, the smaller the index, the better. For example, Samsung lcd40r51b and TCL lcd42b66 have reached the response speed of 8ms, so it's no problem to watch TV, even if you play extremely popular games,No less than professional computer monitor.
.
.
4. Interface is very important.
.
when purchasing.
don't just look at the surface, but also look at the interfaces on the back of the TV. These interfaces directly affect your "investment protection", so they are very important.
at present, the best interface standard for LCD TV is HDMI, This interface is the only digital interface that can transmit audio and video signals at the same time. It can not only simplify the connection and reduce the burden of connection, but also provide huge bandwidth for digital signal transmission. In the future, disc players, computers, home cinemas and other devices will actively use this interface to connect with these devices, You can get the best effect.
if you buy a TV.
you don't want to regret it in a few months, so you'd better choose LCD TV with HDMI interface.
at present.
most LCD TV models of Sony, TCL, Philips, Panasonic and other brands are equipped with such interfaces, and have passed the certification of HDMI organization, so consumers can rest assured when they buy.
.
5 Look at the screen carefully.
pay attention to the bad points.
.
generally, LCD screen will appear more or less "bright spots". "
" bright spots "are hard to detect if you don't look at them carefully, so when consumers buy them, Make sure to observe the screen carefully.
the easiest way is to make the screen black.
see if there are bright spots in a piece of pure black.
then make the screen white.
see if there are black spots.
finally, change it to red, green and blue to check the integrity of the color spots.
if you find that there are more bad spots than the national standard in the process of inspection,
don't buy it.
if there are more bad spots than the national standard
.
6. The viewing angle should be large.
.
when watching LCD TV.
there is also a problem of viewing angle, that is, when the viewing angle of human eyes and the display screen is greater than a certain angle, it may cause the picture display is not clear, the reflection is too large, and the picture can not be seen clearly.
therefore,
the larger the viewing angle is, The more favorable it is to watch TV pictures from all angles.
at present.
the industry recognized viewing angle is 160 degrees to 170 degrees up and down and left and right, which can ensure the viewing needs of most occasions.
at present.
the viewing angle of most brands is about 170 degrees, while the viewing angle of TCL LCD TV series is even close to 180 degrees.
.
.
7. Brightness Contrast can't just look at numbers.
.
when people look at the screen,
they all hope that the higher the brightness and contrast are, the better the picture will be, and the better the detail performance will be.
many manufacturers seize this psychology of consumers.
the parameter values of nominal brightness and contrast.
in fact,
the brightness is 500 lumens, Products with a contrast ratio of more than 600:1 can fully meet the viewing needs. The best way is to feel it by yourself, such as adjusting the contrast to the lowest level and looking at the performance of details in the dark, as long as you feel appropriate.
.
.
8 Don't be careless about the power consumption.
.
finally.
we must pay attention to the power consumption of LCD TV.
although the power consumption of LCD is very low compared with ordinary CRT display devices.
the author still reminds consumers that the power consumption directly affects the service life of the display,The power consumption is high, which not only wastes electricity, but also accelerates the aging of the display lamp. After a long time, the display will turn yellow and dark.
therefore,
try to choose energy-saving products with low power consumption.
for example,
the standby power consumption of TCL b03-p Series LCD TV is less than 1.5W, It can be called a low-power product.
.
.
conclusion:
.
in a word.
when consumers buy LCD TV, they must know more and ask more.
as the saying goes.
it doesn't take much effort to sharpen the knife, they need to know enough knowledge and information, and then they can shop in the numerous products, You can always find what you like.
