This is a guide to the world of TV technology and also a guide to buying a television, which we will not go into too many details louis philippe and principles of work, but we will concentrate on the advantages louis philippe of each technology for the end user.
Technological developments television a few years ago is faster than ever; Every year we witness at least one new concept, that is - if we are to believe marketers - essential even for viewing logs.
This is a guide to the world of TV technology and also a guide to buying a television, which we will not go into too many details and principles of work, but we will concentrate on the advantages of each technology for the end user.
To repeat: LED TVs do not exist - they are "normal" LCD devices with unusual brightness of the screen. Instead CCFL fluorescent lamps use LEDs. But that does not mean they are not interesting contrast. Consume less power, enabling a wider range of colors (RGB LED illumination), and significantly better contrast - but it also depends on the type of deployment.
We distinguish cheaper EDGE LED (LEDs placed around the edges of the TV), and "real" Direct LED, where the diodes placed behind the LCD matrix. EDGE LED TVs are primarily super slim Sony and Samsung devices louis philippe operate with a thickness of 9.9 mm and above, which is thinner than most of the paintings with frame (!).
But besides less power consumption compared to conventional LCD TVs - about 40%, that their advantages over the CCFL devices louis philippe stop. Moreover EDGE LED TVs have problems louis philippe with homogeneity of the image, ie. Halation that irritate.
Plasma televisions have specific drawbacks. Plasma louis philippe can burn; Do you keep the Playstation running over the weekend, will permanently damage it. But this is rare in normal use hinders retention of images, ie. Brief stay static frames. For example, when viewing the movie with the logo of the program and switch to another program, the logo will still be a while (weakly) visible.
Panasonic plasmas are the most resistant to zapržavanje images and retention. Samsung and LG plasmas are quite susceptible to retention, which can irritate. Plasma has a darker image, especially in bright scenes: a large white area on the plasma always looks gray.
Plasma televisions have a perfect viewing angles, while LCD televisions pale watching them askance. The values that manufacturers declare are funny - forget them. Specifically, it looks at the whole family plasma TV from the couch, everyone will see the same picture quality.
With LCD and LED LCD TVs, best picture will see the person right in front of the TV. One place next to it is also OK, two seats away but are problematic. People on the edge of the couch, facing an angle greater than thirty louis philippe degrees to the TV, they will see a gray black color and generally a faded picture.
[Box type = "info"] LCD televisions have the best picture you are sitting right in front of them. Who sits on the edge of the sofa will look more or less faint image - how much depends on the quality and technology of LCD TVs. [/ Box]
Response time shows us how good television when displaying moving scenes. LCD technology is still weak on this point, but it is visible only in the cheapest class of devices which have a 100 Hz processor. From the middle class and above differences are minimal, and only a few will notice that the LCD somewhat sluggish. louis philippe Beaches with 600 Hz subfield drive the fastest televisions on the market.
After setting the screen, LED LCD and LCD televisions classic diagonal 42 "spend from 50 to 100 W, while the plasma of the same size consume from 150 to 200W (older panels). In addition, all plasma is more or less quietly buzzing when the picture is bright, and the principle of work.
Consumption depends louis philippe on the plasma display: brighter movies swallow multiple streams of dark, where the action is happening at night. louis philippe However, despite the improved fuel economy (up to 2 years ago plasmas are spending up to 500 W) difference in consumption compared to LCD is great.
[Box type = "info"] Transferred to rate: Does watching TV five hours a day, saving 42 "LCD in the year to spend about 103 (Orange tariffs), louis philippe while a comparable louis philippe plasma swallow around 200. [/ Box]
Display color depends from the TV to the TV considerably higher than on technology. A great advantage is that the TV THX certification for picture quality: it means that his color and contrast optimal default setting.
Until recently, plasmas have better blacks, but today the technology tie. Cheaper plasmas have very bad (faint) image viewing them per day with plenty of light. In this case, the LCD is a better choice because of the greater brightness of the image, but some models still have a bad view of black at night. We can summarize by class: Cheap TVs - Plasma beats per night, per day The LCD much better choice. The middle class - the LCD is still better by day, by night, mild advantage plasmas. High Class - LCD is still better by day, by night, even better Direct LED TVs.
