Screen.
first of all, let's look at the screen.
the screen of LCD TV can account for 60-70% of the total cost, which is directly related to the cost of LCD TV.

How to choose LCD TV brand

at present, the seventh generation LCD panel production line of upstream suppliers has been established.
a leap has been achieved in both cost and performance, Consumers can give priority to TV products with new panels when they buy them.
take the s-lcd factory jointly owned by Sony and Samsung, which is the first to establish the seventh generation LCD panel production line, as an example.
its production line has been able to produce 60000 substrates per month, and each substrate can cut 8 40 inch or 6 42 inch LCD screens, that is to say, it can support the monthly production of 480000 40 inch LCD TVs, Greatly reduce the cost of the screen, the new screen resolution up to 1366 × In addition,
the physical resolution of the screen is an important indicator to measure whether a TV reaches the high-definition level, and the physical resolution of the high-definition TV should reach at least 1280 × In August 2005, CCTV required dozens of domestic and foreign TV manufacturers to send their flat-panel TV products to the national authoritative testing agency, digital TV product quality testing laboratory for HD testing.
in the test results officially released in September, LCD TV basically passed, but most plasma TV failed, So when we buy LCD TV, we don't have to worry about the physical resolution.

backlight.
different from plasma screen.
LCD screen itself doesn't emit light, and the light we see comes from the backlight system at the back of the screen.
As we all know,
color is not the strong point of LCD TV. This is because the color range of the cold cathode backlight system currently used in LCD TV is only 75% of that of CRT TV, so the new technology of backlight system is worth paying attention to when purchasing. For example, Sony's newly developed and exclusively applied cold cathode backlight system with wide color gamut on its V Series LCD TV, The color range of this new type of backlight has been increased by 30%, and its color performance is almost the same as that of CRT TV.

video / audio processing chip.
the image performance of a LCD TV depends not only on the screen, but also on the internal integrated circuit video / audio processing chip, which is between the signal receiving end and the display end, It is responsible for non-destructive processing and signal optimization, especially for high-definition signal processing, which can test the strength of manufacturers. Although this part of components does not account for a large proportion of the whole machine cost, it needs to have deep technical accumulation and manufacturing knowledge in audio-visual field, Therefore, chips of well-known brands can give us more confidence.
.
.
life span.
this is the most important issue we pay attention to except for audio-visual effects.
at present, the nominal life span of flat-panel TVs is about 60000 hours, but the meaning is quite different: 60000 hours of plasma TV is the life span of the screen. After the life span, the screen, which accounts for 70% of the TV cost, will be scrapped and can only be replaced with a new one, Moreover, its pixels will gradually deteriorate with the use, affecting the image quality; The LCD TV screen does not have the problem of service life. 60000 hours refers to the service life of the backlight. As long as the quality of the TV itself is excellent and the backlight is replaced after the service life, it can get the same effect as the new TV. Although the new generation of flat panel TV has been launched for a relatively short time and the service life of the whole machine has not been verified, from the past experience,A CRT TV can be used for more than ten years. Japanese brands such as Sony and Hitachi should not disappoint people, while domestic and Korean brands can only be tested by time.

finally, don't ignore the problem of compatibility.
nowadays, the function of LCD TV is not only to watch TV programs and movie CDs, but also to be used as a computer, TV, TV, TV, etc Digital cameras, digital cameras and other digital devices display terminal, so rich interface is very important.
at present, all LCD TVs are equipped with composite video terminal, s terminal, component input terminal and other traditional interfaces.
when purchasing, it is necessary to pay attention to the VGA interface which can be connected to the computer, The HDMI high-definition digital multimedia interface can leave us more room for expansion.

finally, we should remind that.
intuitive feeling is an important basis to measure the TV effect. To understand the actual effect of a TV, we should not only read the shopping guide and evaluation articles, but also go to the store to verify it with our own eyes and ears, Feel the excellent performance of those real high-quality LCD TVs in definition, detail, layering, color, motion picture and sound effect.
Skyworth is not bad.
.
LCD color TV has just made a big price reduction. Take Skyworth as an example.
the 37 Inch six color LCD is now less than 8000 yuan, The price of other brands, such as Xiahua, is similar.
for the quality,
the current LCD TV technology is relatively mature. Generally speaking, the quality of each brand is almost the same, and there is no need to consider too much.
as for the after-sales service,
all brands are similar, and the shopping malls may be different, For example, Sanlian has a life-long warranty. You can learn about it in many ways.
in this article, we will introduce the life-long warranty of SanlianIn addition,
shopping malls sometimes make some service commitments with manufacturers, such as extending the three guarantees time. You can pay attention to it..
