What are the differences between the LCD and LED monitors we
frequently hear?
When buying a new TV or monitor, having an idea about the
technology in it can be very useful in terms of getting value for your money.
We have explained the difference between LCD and LED below.
What is an LCD Monitor?
Liquid Crystal Display (LCD) is one of the basic
technologies used in monitors and TVs with a long history. As LCDs became
affordable, they replaced CRT (tube) screens that contain hazardous chemicals.
The LCD has a panel of liquid crystal molecules. Molecules
can take various shapes with the help of electric current, block light or allow
it to pass. A light source is located on the back of the LCD TV or monitors and
illuminates these crystals.
LCDs have red, green, and blue subpixels within each pixel
to produce colors. The transistors inside the screen control the direction of
the light coming out of the pixel so that the light passes through the red,
green or blue filter.
What is LED Monitor?
Light-emitting diodes (LEDs) are small semiconductors that
emit visible light when electricity passes over them. LEDs are generally longer
lasting and efficient than lighting on the LCD. However, let's say that LED is
a type of LCD. Backlight on the LCD is produced by CCFL tubes, and LED is
produced by a series of LEDs. LEDs offer higher efficiency because they can
control the light better.
LCD and LED Comparison
LED displays actually have to be presented as "LED
backlit LCD monitors" but this does not allow creating a new type of
product, both a little long and marketing. However, there are some differences
between the two. In general, it will be enough to keep these two items in mind.
- LED monitors are liquid crystal displays illuminated by LEDs.
- LCD monitors are liquid crystal displays illuminated by fluorescent lamps.
In addition, LED and LCD monitors may have special functions
for actors, cinema enthusiasts and designers.
LED Monitor Types
There are some types of LED monitors. The most common types
include Edge-Lit LED, Full-Array LED, RGB LED, OLED and QLED. While each pixel
produces its own light on OLED displays, QLED (Quantum Dot LED) displays can
offer 90 percent better color accuracy than regular LED displays. This
technology used by Samsung has little to do with "quantum", but it
can offer very good color saturation and contrast.
