LCD, LED, Or OLED: Which Is Best For You?


Digital Screen

When it comes to digital screen technology, three labels come to our minds. These are LCD, LED, and OLED. These three technologies are widespread in use today.

Each of them offers unique features that make them advantageous in various applications. But how do these three differ from one another?

What makes one or the other the most preferred screen for advertising, graphic design, or video sharing?

To help you understand which one works best for a particular application and is most suitable for your needs, we provide you with essential information about LCD, LED, and OLED.


1. Definition Of Terms


A. What Is An LCD Display?


4k LCD vs LED
LCD Display

A liquid-crystal display (LCD) is a flat panel digital display or other EOM optical device that uses liquid crystals and polarizers in its primary operation.

The images will produce when the polarization of linearly polarized lights rotate. The liquid crystals used in LCDs make it possible.

LCDs do not emit their lights directly. Instead, they use a reflector, a backlight, to produce colorful or monochromatic images.

In other words, liquid-crystal displays are not capable of producing their lights. They use fluorescent lamps as backlit that shines through the glass screen, illuminating the crystals.

LCD is the first monitor technology that allowed digital displays to be thinner than the cathode ray tube technology. LCDs have become well-known because of the existence of flat-screen display monitors.

Many of the LCDs are still in the active phase as of today. LCDs are widely used in computer monitors, televisions, aircraft cockpit displays, projectors, and other digital signages. LCDs are also commonly found in portable digital electronics like mobile phones, digital camcorders, digital clocks, watches, and calculators.


B. What Is An LED Display?


LED Display Lamp

Light-emitting diodes display is also a flat panel display that uses multiple LEDs as its light source. It is named after the backlighting technology used to make it the light-emitting diodes.

The development of LED panel screens is in conjunction with an LCD screen/monitor. The LED display also features liquid crystals that block and pass light, though not a fluorescent lamp. Instead, it uses extra small lights called LEDs as its light source.

There are two backlighting methods used in LED screens. One is full-array backlighting, where LEDs are situated evenly across the entire screen panel; the other is Edge Lighting, where LEDs are placed only on the screen edges.

LED displays have been around for over 50 years already, but what makes LEDs popular is when the white LEDs are developed. LEDs became a preferred alternative as a source of light on screens and at home in general.

They are now widely used in different signages, advertising screens, public vehicles, even decorative lights for stage lighting, etc.

The LED display can produce sufficiently bright light that is detectable even if you put your screen outdoors under direct sunlight.


C. What Is An OLED Display?


An organic light-emitting diode or organic LED is a flat panel light-emitting technology that does not need a backlit because it produces visible light.

OLED Technology

The OLED screen has thin films of organic compounds placed between two conductors inside the screen. When the flow of electric charges goes through those emissive electroluminescent film layers, they emit light.

Because of the carbon-based organic plastic materials used for OLED screens,  OLED screens can now be thinner and lightweight but still produce bright light.

Nowadays, OLED technology creates digital screens in electronic devices such as computer monitors, tv screens, cell phone screens, game consoles monitors, etc.

The OLED technology has two (2) varieties: The RGB OLED and The White OLED. The former uses red, green, blue pixels that produce white light when electric charges go through it. White OLED uses white light that goes across a color filter. As a result, it creates different colors visible on the screen.

Most OLED screens can also be made transparent and flexible. Transparent OLEDs are used in smartphones with fingerprint scanners, and flexible OLEDs are utilized in foldable mobile devices.

OLEDs are considered the modern digital display technology of today.


2. Technology


A. How Does LCD Technology Work?
Micro LED vs OLED
LCD Display

The LCD screen has millions of tiny blocks of picture elements called pixels. These pixels have red, green, and blue colors, which switch on and off rapidly to make a moving colored picture. The liquid crystals cause the switching of pixels.

A light source shines towards the screen behind each light crystal display (LCD). And in front of this, millions of pixels with polarizing glass filters are placed. Another glass filter is placed next to it at 90 degrees. A liquid crystal can be twisted and untwisted between these two filters electronically.

The liquid crystal rotates the light 90 degrees to move through the filters when switched off. This will make the pixels to be bright. On the other hand, it will not twist the light to get blocked by the second polarizer when switched on. This makes the pixel look dark.

These pixels can be switched on and off multiple times within a second. That resulted in the moving picture you can see on the screen.


B. How Does LED Technology Work?


LCD vs LED Display
LED Display Module

The LED screens work by emitting light in red, green, and blue colors directly from the screen display’s surface.

LED displays can produce display images and pictures, but they can also general illumination.

The light is created via electroluminescence in the semiconductor materials found in LED screens.

When an electric current passes through a light-emitting material, the electric current’s electrons fill up the electron holes. When an electron passes through liquid crystals, the electron fills the electron holes, resulting in photons’ emission, otherwise known as light.

Three light configurations are applied in LED screens: the direct-lit, edge-lit, and full array.

Direct-lit uses the least number of light-emitting diodes. The LEDs are more extensive and cannot be operated individually. It is ideal for more comprehensive and cheaper LED displays.

In edge-lit LED screens, the LEDs are placed only at the edges of your screen. This type of configuration is commonly used in LED TVs.

Complete array configuration has LEDs equally distributed within the screen to produce more consistent and dynamic colors.


C. How Does OLED Technology Work?


OLED Screen

The OLED display is made up of carbon-based conductor materials. When electric charges are applied to these materials, they produce light.

The most simplistic way to make OLED work is by placing an emissive electroluminescent layer between the cathode and the anode materials. The cathode releases the electrons, and the anode removes them.

We can drive the OLED screen displays with passive-matrix and active-matrix control schemes. A Passive-matrix control scheme only allows sequential control in LED display, meaning one by one.

The active-matrix control scheme contrarily uses a film transistor that gives you direct access to individual pixels, allowing you to switch on or off each pixel.

Unlike LCDs, OLED only uses one glass panel because it does not need a fluorescent lamp or backlight like an LCD. This makes OLED screens thinner and has deeper black color since each LED is individually lit.

Modern OLEDs are even bi-layers—many new ways to construct OLED screens in today’s advanced digital technology use various layer configurations.


3. Differences Of LCD, LED, And OLED


A. Brightness


LCD vs LED Projector
Indoor LED Display

The LED display offers the best brightness level when it comes to brightness level.

LED uses self-light-emitting diodes that give LED screens a high brightness level. On the other hand, LCD uses CCFL technology that only uses a backlight. It does not produce its light. LCDs can also make ample brightness for digital display, but they cannot level with LED screens’ brightness.

OLED can also offer a decent level of screen brightness. Because OLED has the most blackness level (essential for displaying high-quality images), it contrasts dark spots and shines on the screen.

Unfortunately, you cannot keep your OLED screen at its max brightness level because it will result in a reduced lifespan.

It means that if you are only considering which screen can deliver a high brightness level for continued use without affecting the screen’s performance, the LED screen is the best among the three.

Ranking: 1. LED; 2. OLED; 3. LCD


B. Color Quality/Brightness


LED vs LCD Which Is Better
Display Brightness

Like you, one of the qualities users look for in the digital screen is its ability to deliver excellent color performance. Creative visual display with impressive graphic effects and animations will only be as effective as it should when played using a screen that can produce high-quality colors.

With this consideration, your choice must lean towards the OLED display. The more advanced technology used in OLED allows better color portrayal.

The OLED screen can offer a high-definition resolution, especially in dark rooms. Because it has a more profound black quality that gives it a higher ratio contrast, it provides your visual display extra depth.

However, the LED screen offers better color brightness, richer tone, and better color accuracy. Because of the LED screen’s improved RGB light technology, you can also have a high-quality display with well-saturated colors.

Again, since LCDs do not have their light source, we cannot compare the color quality to LED-powered displays.

If you search for an electronic display screen that you can rely on for its high-definition resolution, you can choose LED or OLED.

Ranking: 1. OLED 2. LED. 3. LCD


C. Contrast Ratio

The OLED offers the highest contrast. When you turn off your OLED screen or go black, no light is produced by its pixels. That is the darkest a digital screen can go. That also means that you can have an infinite contrast ratio with OLED.

The LED screens come second in this list. The LED screen also offers a good contrast ratio. It gives a high enough contrast ratio to display high-quality images. This screen is also an excellent choice if you seek a screen with good contrast.

LCD is third on the list. Since LCD screens are highly dependent on the backlight, you may notice that the black portions of images displayed are not black because the separate backlight reflects through the screen surface. This is most evident when you place the screen in a dark room.

Ranking: 1. OLED; 2. LED; 3. LCD


D. Viewing Angle

LED Wide Viewing Angle

Viewing angles is another essential aspect of digital screen displays because the audiences view a digital display not always parallel to their faces but from various angles.

OLED vs. LED. For this one, OLED offers a better viewing angle. The main reason is that OLED technology is thinner, and its pixels are closer to the surface. You can view OLED digital screens from an extreme viewing angle with no screen luminance degradation.

LED vs. LCD. We can say that LCD has the worst viewing angle; LCD generally has a lower viewing angle. If you notice that your monitor or screen looks shadowy from some angles, that can mean that it uses a nematic panel- an LCD panel that offers a low viewing angle.

Overall, the viewing angle category shows that OLED and LED have a more significant advantage.

Ranking: 1. OLED; 2. LED; 3. LCD


E. Price Point


Mini LED vs OLED
LCD Screen

LCD vs. LED display. Affordability-wise, you can expect that an LCD screen display is less expensive than an LED display. LCD TV or LCD screens are cheaper because of the technology used to manufacture them. LCD screens are thicker and use an older version of lighting technology than the one used in an LED display.

LED vs. OLED. Typically, the more advanced the technology is, the higher its price market. That analogy is perfectly applicable for mini led vs. OLED display price comparison. Since OLED utilizes newer technology, you can expect that it is also more expensive.

For OLED vs. LED vs. LCD screens, it is apparent that you can purchase the LCD screen at a cheaper price point.

Ranking: 1. LCD; 2. LED; 3. OLED


F. Performance/Lifespan


LED vs LCD Screen

To know which is better, LED vs. LCD, use the first five differences as your basis for performance. Those aspects typically constitute a screen performance.

When it comes to lifespan, LED displays can have a longer lifespan.

This is mainly because LED bulbs can last longer than any fluorescent lamp.

The LEDs may remain running for more or less (10) years, while fluorescent lamps can only last for less than five (5) years.

Both the LED and the OLED screens use LEDs. Since screens have been around for a long time, it has already proven their ability to last longer and be a reliable digital screen that serves various purposes.

While the OLED is still considered new technology, it has yet to prove that it can have a longer lifespan.

For this category, the LED screen is the most preferred option.

Ranking: 1. LED; 2. OLED; 3. LCD
