How LED TV’s Differs from LCD

Before knowing the difference between the LED and LCD TV’s, it is very important to know how they work.

What Is An LCD?

LCD is an abbreviation for Liquid Crystal Display, LCD is a tube based technology facilitate a high definition picture with a very thin screen, and had derived as the empathic high definition technology. Apart from the Television LCD also enable mobile, tablets and computers systems. Liquid Crystal Display uses either a passive matrix or an active matrix display grid. An active matrix has a transistor located at each pixel intersection, requiring less control luminance of a pixel. LCD comes into 2 segmentation – IPS (In-Plane Switching) and TFT (Thin Film Transistor). TFT is characterized as an active matrix LCDs, which means that they can cumulatively retain pixels on the screen while also addressing other pixels using the minimum amount of the energy. On the other hand, IPS technology is an improvement on traditional TFT display module in the sense that it has the same basic structure. IPS technology is more stable & quicker, wide viewing angles and high transmittance as a comparison of TFT. Nowadays, LCD TVs available in the market in different variance and sizes like 50 inch, 55 inch, 65 inch, 32-inch ultra HD TV and much more sizes.

What Is An LED?

The term LED, stands for Light Emitting Diode, we can say an LED is an improved version of LCD TV as it uses the LEDs to backlight the display rather than the cold fluorescent lights. Edge lighting and local dimming is the two main features within the LED for backlighting. Edge lighting is most common within LEDs, in the beginning, it had some problems with inconsistent screen lighting patchy colors but the significant improvement in edge-lighting is now a favored technology. On the other hand, local dimming varies the backlight in the different part of the screen to give richer, darker blacks and brighter whites required. LEDs are also available in the resolution of 55 inches LED TV, 50-inch smart LED TV, 65 inches LED TV and much more.   

LED VS. LCD

The only major difference between the LED and LCD is the system of the backlighting between these two televisions, not the chips that produce the image content. There are 3 forms of backlighting in LCD – CCFL Backlighting, Full Array and LED edge lighting. TV manufacturers make a big deal out of LED because the sets that use the technology are usually more energy efficient than CCFL (Cold Cathode fluorescent lamps ) LED TVs. Since both LED and LCD uses the LCD technology, you’re probably the wonder what the different these two technologies. Nowadays, all LCD TVs uses LED lights and are colloquially considered LED TVs.
