OLED vs LCD

OLED or LCD displays will likely be your display type of choice if you're building a display application or determining what kind of TV to buy. When deciding which is best for your specific application, you must take into account the different strengths and drawbacks of OLEDs and LCDs.

Which Display Is Best For Your Application: OLED or LCD?

Uncertain which option will work best for you? Not to worry! We're available to assist you in selecting the ideal display for your undertaking or need. We'll break down the advantages and disadvantages of each display kinds in this post so you can choose the one that's best for you.

Why Are OLED and LCD Displays Different?

The method used to create the images differs between LCDs and OLEDs. Liquid crystals, which are used in LCD displays, turn light into an image. OLED displays produce images by electrically irradiating the organic components inside the display.

Some elements of display technology, including as contrast, brightness, viewing angles, longevity, black levels, picture burn-in, and price, are significantly impacted by these various technological techniques.

Things to take into account when selecting an OLED or an LCD

This choice will be influenced by a variety of factors, including the environment in which your display will be utilized, your budget, the lighting setup, and the required durability.

To choose the best display type for your application, you must consider the advantages and disadvantages of each.

Contrast

The distinction between an image's lightest and darkest areas is referred to as contrast. Images and text will be crisper and easier to read when there is high contrast. It's essential for high-quality graphics and images as well as for making sure that a display's content is clearly apparent.

Most LCD screens come with a built-in backlight by default to make the graphics and images visible. This is the reason why, on an LCD monitor, display, or television, light can still be seen through graphics that are supposed to be black.

OLEDs, in contrast, give a significantly better contrast by regulating each of its individual pixels dynamically. The pixel totally turns off when the color black is used in an image on an OLED display, producing a far better contrast than an LCD.

Brightness

OLEDs and LCDs differ significantly in that LCDs have an LED backlight whereas OLEDs do not. OLED displays often have an edge in terms of individual pixel brightness because each pixel is separately illuminated. Since OLEDs do not rely on a separate backlight source, they may produce more intense brightness at the pixel level. However, LCDs frequently triumph if we take into account the overall brightness of the entire panel. This is so that an overall brighter image may be produced by LCDs' steady backlight, which illuminates the entire display area. Additionally, since the backlight always illuminates the entire display, even if only a few pixels need to be lighted, LCDs may have more "wasted" light.

In conclusion, depending on whether you're comparing the brightness of individual pixels or the brightness of the entire screen, you may determine whether an LCD or an OLED display is brighter. In general, LCDs can have a brighter overall display while OLEDs may have brighter individual pixels.

OLEDs have no backlight because they are self-illuminating. This indicates that LCDs' potent backlights enable them to produce brighter images.

If your display will be used outside or in an area with high ambient light, it should have a high brightness level. If the display will be utilized indoors or in low light conditions, the brightness level is less crucial.

Viewing Directions

Have you ever turned your head to one side of a screen and observed that the visuals started to look washed out or shadowy? The image looks to be worse the further you are from the "front and center" view. This illustrates how viewing angles work: the better the visuals on the screen look when seen from various perspective points, the broader the viewing angle.

When seeing displays that aren't always straight on, a wide viewing angle is crucial. Wide viewing angles enable the images on the screen to maintain consistency and quality regardless of the angle from which the viewer is seeing them.

OLED displays don't have backlights, as we already explained in the previous part. As a result, they have a naturally broader viewing angle since they are much smaller than LCD displays and have pixels that are much closer to the surface of the screen.

From almost any angle, images on OLED displays retain their quality and legibility. The most prevalent kind of LCDs do not.When tilting an LCD or viewing it from different angles, you'll frequently find that images get distorted or lose their hues. However, a lot of LCDs now have technology, notably In-Plane Switching (IPS), to make up for this.

IPS LCDs have viewing angles that are comparable to OLEDs and are substantially brighter than regular LCDs.

Lifespan

Compared to OLEDs, LCDs have been on the market for a longer period of time, therefore more evidence supports their lifespan. The typical lifespan of an LCD has been demonstrated to be 60,000 hours, or 2,500 operating days.

Most LCDs should perform consistently for around 7 years. Although some backlight dimming has been noticed, it has not significantly affected the display's quality.

OLEDs are a more recent technology in the display industry, which makes it more difficult to review them in depth. OLED technology is not only developing quickly, but there hasn't been enough time to fully evaluate their performance.

OLEDs of the present are expected to operate reliably for 100,000 hours with regular maintenance. That equates to 10 years of 10 hours every day.

The susceptibility of OLED to picture burn-in must also be taken into account. If a static image is shown for an excessively long time, the organic material in these displays may permanently leave an afterimage on the screen.

Therefore, the longevity of your OLED may be significantly impacted by how it is utilized. An OLED that displays dynamic, continuously moving images will last longer than one that displays static images for extended periods of time.
