The television manufacturers are now using the latest technologies to create advanced systems, so you will find many different options on the market. The many choices can make it difficult for you to find the best TV. However, all is not last as the following article will tell you about two types of TVs. After reading this, you should be able to tell the difference between an LCD and LED TV.
When you are not familiar with the latest TV technologies, you will find it difficult to choose between LED and LCD televisions. Even though the two sets use the Liquid Crystal Display technology, you will notice a key difference in the LED as it uses the Light Emitting Diodes and the regular LCD uses the fluorescent lamps.
LED TVs have flat screens as well. These televisions have two types of backlighting, the Full Array and the Edge. Full-Array lighting has many rows of light emitting diodes at the back of the screen surface to give more control over brightness and dimming as you could switch the diodes on and off. The Edge lighting uses diodes which are arranged on the screen’s exterior edges for the light to spread across.
LCD TVs have flat panels with two layers of combined polarized glass. One layer has the liquid crystals which block or pass the light to show images. The crystals don’t produce light of their own as it will come from the fluorescent lamps at the back of the screen. These are arranged inside a grid with millions of shutters opening and closing to release and capture the light to produce images. Every shutter pairs with a colored filter that can produce a sub-pixel. These sub-pixels are very tiny and they unite to produce one pixel. This is displayed on the screen as one speck of color. Aside from the fact that LCDs create top-quality images, they can be very thin and will occupy less space.
In addition, the Edge-lit LCDs are usually thinner and lighter than the Full Array since the lighting source occupies less space. The full-array TVs are heavier and thicker, but you could dim one part of the LED panel and leave the other bright to improve contrast and blacks in images.
Finally, one more obvious difference between an LCD and LED TV is that the latter is more expensive. Ultimately, the choice is yours as each type has its own benefits and drawbacks.
