LCD TV is a good brand

.
don't watch their demo discs.
and don't listen to the salesperson.
just take an ordinary DVD, whose picture you are most familiar with is better than.
you can know whose one is better, and what your eyes see is true.
your eyes are mainly in three aspects: clarity.
color, sound and clarity: see whether the edges and corners of small words appear on the screen are clear or not; See whether the overall feeling of the screen is transparent, whether it is "clean", whether there will be a layer of gray fog; Look at the number of snowflakes in the black scene on the screen; See if the lines in some directions are smooth, whether there are burrs and serrations.
.
with my five or six years of experience in shopping malls.
this is the most simple and effective way.
.
I also collected some professional experience in purchasing machines! If you are satisfied, please give me extra points<
.
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. However, it's better 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 The resolution is a very important index of LCD TV.
however, we should not blindly think that the larger the resolution, the better. LCD TV generally has the best resolution,It is also called maximum resolution, under which the LCD TV can display 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, 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. These interfaces directly affect your "investment protection", so they are very important.
at present, the best interface standard for LCD TV is HDMI, The 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 a huge bandwidth for digital signal transmission. In the future, disc players, computers, home cinemas and other devices will actively use this interface, which can be used to connect with these devices and achieve the best results.
if you buy a TV.
don't want to regret it in a few months, So it's best to buy LCD TV with HDMI interface.
at present.
most models of LCD TV of Sony, TCL, Philips, Panasonic and other brands are equipped with such interface, 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. Therefore, when consumers buy, they can't see them, You must 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,
.
.
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 human eyes and display screen is larger 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,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 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 will be 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 level to see the detail performance in the dark, As long as you feel appropriate.
.
.
8. Don't be careless about power consumption.
.
finally.
you 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, And it is 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 Bodian b03-p Series LCD TV is less than 1.5W, which can be called a low power consumption product.
