The main differences between LCD and LED TVs

September 11, 2019

Technically , LCD and LED TVs are almost identical products , the difference is that LED TVs use liquid crystal molecules that are placed on the screen (Liquid Crystal Display) to produce a sharper and more accurate image.

It is thin, has polarized glass, and blocks light from outside to enhance the image coming in. LED technology has significantly reduced the cost of its predecessor, both of which have their strengths and weaknesses, which we will discuss with you.

What is the difference between LCD and LED TVs?

The main difference between LCD and LED TVs is how they generate light behind the screen. Like the original TV technology, LCD TVs use a highly-efficient fluorescent lamp behind the screen to generate light that illuminates the pixels on the screen.

In contrast, LED TVs do not have such a tube, they have micro-lamps of many diodes, which allows for more control over the illuminated screen.

Due to their small size, such lamps can be placed both behind the screen and at the edges to obtain an even sharper and more accurate image.

Image quality

The sharpness of a TV image is directly related to the refresh rate of the screen, the number of times the image changes per second. Instead of seeing a moving image on the screen, we see frames on TVs that give us the illusion of a moving object, and LED TVs allow us to get a higher quality, clearer, updated image than their LCD predecessors.

Also, as we know, all televisions emit 100Hz radiation, which we cannot see, but it affects the human body, organs, vision, and psyche.

It is primarily manifested by a feeling of fatigue and eye pain after watching TV for a long time. LED screens have an image flicker frequency of 480 HZ, which is absolutely safe and has no negative impact on humans, and the image quality is also better.

LED lighting control

LED TVs allow for greater control over brightness and contrast, because the way the diodes are built can quickly control the brightness and contrast of the light, giving us sharper blacks and whites.

LED lights can be individually dimmed and brightened, while on LCD TVs this is only done by dimming or blocking part of the screen.

Energy efficiency

LED TVs are much more economical than LCD, the reason for this is that they can turn off the lamps when needed (for example, when the image is black), and in addition, diode lamps are already considered the most economical, and this one consists of such lamps.

If energy efficiency is an important factor for you, then an LED TV is the best solution here too, as it consumes about 40% less electricity than an LCD.

Considering all the above factors, the result is that LED TV is a much more modern technology than LCD, which has a much better quality screen, is economical, radiation-safe, thinner, but also more expensive.

LCD TVs still remain firmly on the market and the demand for them is not decreasing due to the price. It should also be noted that the quality of their screens has improved recently, but the price has not increased.
