LED VS LCD technology
Presence time LCD and LED are popular technologies for
displaying texts and images. LCD and LED are extensively used in display
screens in various electronic devices such as TVs, computers, laptops,
smartphones, etc. There are many differences between LCD and LED displays. One
of the significant differences is that LCD uses liquid crystal and cold cathode
fluorescent lamps to produce images on the screen. On the other side, LED uses
a PN junction diode which emits light when the current passes through it that
is used as a backlight in the display.
In this article, we will explain the differences between LED
and LCD.
LED:
LED stands for light-emitting diode. LED is a type of LCD that accompanies the advancement of technology. A semiconductor light source emits light when current flows through it. It uses an array of light-emitting diodes as pixels for displaying images. It comprises two sheets of polarising material with a liquid crystal solution between them.

LEDs are usually found in smartphones, televisions, computer monitors, and instrument panels, and use a liquid crystal display panel to control where the light is displayed on your screen.
LCD:
LCD stands for liquid crystal display. A liquid crystal display or LCD combines the solid state of matter and the liquid state to produce a display effect. It uses liquid crystals for the formation of a visible image. The LCDs are super-thin technology displays
This technology is used in laptops, digital clocks, watches,
digital cameras, etc.
Significant differences are given below:
✅ Backlight:
Backlight is an essential difference between LED and LCD
technology. These two use backlight to provide an image on the screen.
👉 The LED monitor uses light-emitting diodes, which are tiny
lights. The LED backlight comes in two ways full array backlight and edge
lighting.
👉 While an LCD monitor uses CCFL (Cold Cathode Fluorescent
lamps) for backlight, these fluorescent lights are evenly placed behind the
screen to deliver consistent lighting across the display.
✅ Screen
Thickness:
👉The LED display uses flaunt and thinner screens with sharper
edges; however, LCD uses the two-layer display technology to add bulk. Hence,
LED screens are thinner than LCD screens, as they do not require a separate
backlight.
✅ Brightness:
Brightness is a crucial difference between LCD and LED
displays. Comparing this technology to the parameter of brightness, an LED
display stands out as a winner. This is because it uses an individual dimming
and backlighting system, which, compared to LCD, makes your projection more
defined, authentic, and closer to reality.
✅ Picture
quality:
👉 LED delivers good picture quality in comparison to LCD. It tends to have better contrast and deeper blacks than LCD screens.
👉 Whereas LCD
also provides good picture quality but less than LED.
✅ Response Time:
👉 LED displays have a faster response time than LCD displays, which means that they can display fast-moving images more smoothly and with less motion blur.
👉 LCD display have not faster then LED.
✅ Refresh Rate:
👉 LED displays typically have a higher refresh rate than LCD displays, which means that they can display more frames per second and reduce motion blur even further.
👉 Lcd display have lower refresh rate then Led.
✅ Viewing
angles:
👉 LED displays do not behave like LCDs. The LCD screen can be
difficult to view from certain angles, as the display may appear washed out or
distorted.
👉 LED displays have no limitations in viewing angles because
they have a broader viewing angle.
In comparison to LCD screens, LED displays are noted to have
better viewing angles.
✅ Power
Consumption:
👉 LEDs are more energy efficient because these models use
Light Emitting Diode (LED) for backlighting. These consume less power than cold
cathode fluorescent lamps (CCFL) used in traditional LCD televisions. Power
savings are typically 20-30%.
✅ Contrast/Black
Levels:
👉 When it comes to contrast ratio, LED screens come out on top. Covering dark regions of the image on the screen and allowing the audience to view every aspect of the image without being frustrated is a great idea. In comparison to LCD screens, LED displays have higher contrast.
👉 The LCDs cannot
create black areas on the screen, resulting in a loss in image quality.
✅ Mercury
Presence:
👉 Mercury is used for the production of LCDs. This is the
reason LCDs are not environmentally friendly.
👉 Whereas LEDs do not require mercury for their production.
They are environmentally friendly.
✅ Sizes:
The best part about an LED display is that it can perfectly
fit your space. You can buy LCDs ranging between 13 to 57 inches in size and
LEDs up to 90 inches, based on the available space.
✅ Color Gamut:
👉 LED displays generally have a wider color gamut than LCD displays, which means that they can produce more vivid and accurate colors. This is especially true for OLED (Organic Light Emitting Diode) displays, which are a type of LED display that uses organic materials to produce light and can achieve even better color accuracy than traditional LED displays.
✅ Price:
👉 LED displays are more expensive than LCDs. However, this is
only true when the purchase price is considered.
👉 When considering factors such as lifespan and maintenance,
an LED display is cheaper than an LCD in the long run.
Which is best LCD or LED?
LED
and LCD are the latest technologies, but LED has various advantages over LCD,
making it better.
