So, you were just thinking that you have got a branded Television having latest technology and the term “LED” just came out of nowhere that changed the trend in televisions, isn’t it? Most of the televisions today use this technology that has made the consumers enjoy more clarity and detailed picture quality than before.
LCD is a kind of panel. It actually makes colours, but doesn’t produce light. It is where all the pixels reside. On the other hand, LED is backlight behind that LCD panel. Without backlight, we can’t see LCD’s picture.
Televisions that use series of LEDs (Light Emitting Diodes) are termed as LED TVs. It uses it in order to backlight LCD panel. Let us explore more about both of these technologies viz. LED and LCD and know how different features of televisions are affected by it!
The overall process by which the light from LEDs that are positioned on edges of screen gets projected across back of LCD screen as contrary to directly behind it is called edge lighting. While this works well, it may result in bands or blocks of lighter pixels in or around the areas that are meant to be dark. Due to this, local dimming of the edge-lit televisions may sometimes result into some kind of murkiness in the dark areas as compared to fully arrayed LED TVs.
QLED and OLED
Once you will start exploring more about LED TVs, newer acronyms will likely pop up that may confuse you at first. The two that you are likely to find first are QLED and OLED. While both of them just sound similar, they two are different.
OLED (Organic Light Emitting Diode) displays use panel of the pixel sized organic compounds which responds to the electricity. It allows deep contrast ratios as well as better accuracy in picture. You will find OLED displays on high end LED TVs.
On the other hand, QLED TVs come with upgraded illumination technology that is more efficient than their counterparts. It implies brighter and better colour and grey scale and improves HDR (High Dynamic Range).
If you desire for the one having best picture quality among LED TVs, you will require high end model having full array backlighting along with local dimming. Individuals LED zones can be brightened or dimmed independently that makes it more flexible and suitable according to the preference and taste of an individual.
So, LED TVs have more advanced technology and better picture quality that can obviously cost you more. However, it is all up to the buyer to find out the one that can best suit their individual needs.
