Pay attention to the purchase of LCD TV
When purchasing LCD TV, you should pay attention to.

Which brand of LCD TV is the best?

.
1. Pay attention to whether the display size is complete.
.
at present, the mainstream sizes of LCD TV are basically 27 inches, 32 inches and 37 inches.
these have been able to meet the viewing needs of living room and bedroom, but here we should remind that the best thing is to buy brands with rich product lines, for the simple reason, The products of these brands basically use the "sixth generation" LCD panel production line, and only the products offline from these production lines can truly meet the requirements of HDTV.
at present.
the product sizes of mainstream brands mostly include 42, 37, 32 and 27 inches.
.
.
2 See clearly the resolution.
.
resolution is a very important indicator of LCD TV.
however, 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, under which the 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,For example, when watching a football match, if the response time is not good, there will be drag shadows on the screen, which will affect the viewing effect.
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 enjoying TV programs.
of course.
the smaller the index, the better. For example, Samsung lcd40r51b and TCL lcd42b66 have reached the response speed of 8ms, It's no problem to watch TV. Even if you play extremely popular games, it's no less than a professional computer monitor.
.
.
4. The 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, which directly affect your "investment protection", Therefore, it is very important.
at present, the best interface standard for LCD TV is HDMI, which 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 required for digital signal transmission. In the future, disc players, computers, home cinemas and other devices will become more and more popular, If you don't want to regret it in a few months, you'd better choose LCD TV with HDMI interface.
at present.
most LCD TVs of Sony, TCL, Philips, Panasonic and other brands are equipped with this interface, And has passed the HDMI organization's certification, when consumers purchase, they can rest assured.
.
.
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 consumers must carefully observe the screen when they buy.
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 black Check the integrity of the blue color dots.
if you find that there are more bad points than the national standard in the process of inspection,
do not buy.
.
.
6. The viewing angle should be larger.
.
when watching LCD TV.
there is also a problem of viewing angle, that is, when the viewing angle of people's eyes and display screen is larger than a certain angle, The bigger 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, The viewing angle of TCL LCD TV series is even close to 180 degrees.
.
.
7. Brightness and contrast can't just look at numbers.
.
when people are looking at the screen,
they all hope that the higher the brightness and contrast, the better. Of course, the picture is more beautiful, The better the detail performance.
many manufacturers grasp this psychology of consumers.
the parameter values of nominal brightness and contrast.
in fact.
products with brightness of 500 lumens and contrast of 600:1 or more can fully meet the viewing needs. The best way is to feel it by yourself, such as adjusting the contrast to the lowest,The power consumption of LCD TV must be paid attention to.
although the power consumption of LCD TV is very low compared with ordinary CRT display devices,
the author also wants to remind consumers that the power consumption directly affects the service life of the display, It is not only a waste of electricity, but also easy to accelerate 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.
