How to choose large screen ultra thin LCD TV?

in the past, the rear projection products were often large, thick and bulky.
but now they are different.
not long ago.
TCL launched the "dream" series DLP flat panel light display rear projection, One of the dlp61v6 is only 17.4cm thick.
If a 60 inch TV is only a little more than 17cm thick.
it's not too much to call it a flat-panel TV! The principle of DLP light display TV is to reflect light through millions of small mirrors embedded on a chip the size of a fingernail and project it onto the screen to form an image.
these small mirrors can be tilted in an electrostatic manner independently Closed.
it can open and close more than 5000 times a second.
so this technology is also known as digital micromirror technology.
because of its imaging principle.
this kind of rear projection TV has the advantages of high brightness, high definition, pure digital, long life, low energy consumption, low calorific value, etc.




although LG, Skyworth Samsung and other manufacturers have DLP rear projection products.
but TCL is the first one to achieve such thickness.
tcldlp61v6 adopts the third generation DMD chip.
its service life is up to 50 years, ten times that of LCD, The UHP bulb of high-performance Philips has a service life of 10000 hours.
although it has a 61 inch large screen.
due to the advanced optical design of TCL Thomson company, its thickness is only 1 / 3 of that of ordinary DLP rear projection TV, and its body thickness is only 17.4cm, which is the thinnest rear projection TV in the world.
the whole machine weight with pendant is less than 59kgTcldlp61v6 is lighter than ordinary 34 inch color TV.
tcldlp61v6 can be completely installed on the wall.
therefore, it is called "rear projection that can be suspended."



in terms of performance.
tcldlp61v6 adopts the optics and machinery of American FTV company, and the projection screen is from Japanese Cola company, These two technologies enable TCL's DLP flat panel optical display rear projection to have 16.7 million true colors (24 bits), 1024 gray levels (10 bits), high contrast close to 1000:1, and high chroma bandwidth of 15MHz -, This product has been listed in Beijing.
if you need a large flat panel TV with a size of more than 61 inches at home.
and you don't want to spend a lot of money, this product is more suitable, Its price is more than 70000 yuan.




led by plasma pressure array LCD

in fact, LCD TV has the highest definition and other indicators in flat panel TV, However, in the second half of this year, the price of LCD and plasma TV has dropped again and again, and the current price is very cheap, And there won't be a big price reduction before the Spring Festival.
here's what you should pay attention to in selecting this kind of TV.



at present, Hisense is the best domestic brand in this kind of TV.
Konka, Skyworth, TCL are also good.
compared with imported brands.
these domestic products have good price performance and good quality.
the price of these domestic products is very good


Let's take Hisense's products as an example.
the real Top Digital HD supports 1080p signal display.
there is a dedicated digital channel, and the LCD is no exception.
the backlight determines the brightness.
Hisense uses cold cathode fluorescent lamps, which are thinner, with high luminous efficiency, low current, high brightness and long service life (more than 50000 hours) All 32 inch products are 16 lamp tubes.
double prism plate is used.
the light source can be doubled, the brightness can reach 500 nits, and the contrast can reach 600 ∶ 1.
in addition, pay attention to the energy-saving mode of LCD TV.
for example, Hisense tlm-32772619 uses EEFL cold cathode fluorescent tube as the backlight source.
energy saving mode is also set in the menu, which can effectively reduce the brightness of backlight source, The real-time protection and life extension of backlight source can effectively reduce power consumption and save 40% of electricity, which is especially suitable for the environment with low light at night.
note.
the energy-saving mode here is to reduce the brightness of backlight instead of simply dimming the brightness.
the response time is shorter.
Hisense 3277, 2619 and 2020 are only 16ms, In addition,
the horizontal and vertical vision should be more than 170 degrees.
the color should be more than 16.7 million colors.
it is better to have a relatively hard protective screen.
when you purchase, you can tap the screen with your hand to see whether there is a protective screen.
in terms of resolution, it is better to reach 1280 × 1024.
in this way, it can be used as a professional computer display.



it should be noted that.
in this way, it can be used as a professional computer displayFor a 15 inch LCD screen, the cost difference between the special screen and the ordinary screen is more than 1000 yuan.
in order to reduce the cost.
on the low-end LCD TV, It has become a secret shortcut in the industry to change the special screen into ordinary screen.
so when you buy, you'd better recognize the relatively large and reliable brand.
