There are 3 types of LED TVs

There are 3 types of LED TVs:

* Edge Lit Screens: These have LED lights placed around the rim of the screen. This is done using a special type of diffusion panel which spreads light evenly behind the screen. It is also the most common type of LED screen, and is the thinnest of the three.
* Dynamic RGB LED Lights: These are positioned behind the screen instead and allow dimming to occur in locally specific areas of darkness on the screen.,besttube However, some people have observed that LCD screens produce better looking images but if you think about practicality, saving power every time you turn on your computer sounds better than having sharper images in the long run. This allows the TV to present better black and white levels at pretty high dynamic contrast ratios. The only disadvantage of this is that small bright objects with dark backgrounds are shown in less detail.,ledbright LED technology can be found at a lot of gadgets these days and these have become trendy gifts that people give to their loved ones during special occasions.
* Full Array of LED Lights:These are arranged behind the screen but cannot be dimmed or brightened individually. This type of screen has a lot of advantages as these TVs save more power, have better brightness and contrast, as well as better response time and colour reproduction.,inflatable life jackets One thing to remember which can be considered when using any type of bulb is "Do not look directly at the light", the light that a LED bulb gives off is an intense low light so it can be very dangerous for your eyes if you look directly at it. This is definitely the best of the lot, but TVs using this technology are generally more expensive.
