Advantages of OLED screens compared to conventional screens

One of its benefits is that the emission of blue light is considerably reduced, thus minimizing the negative effects it generates.

In the world of technology, constant evolution seeks to improve our digital experiences. One of the most notable advances in the last decade has been the introduction of OLED displays . These screens have revolutionized the way we interact with visual information on our electronic devices.

Conventional displays, such as LED-backlit or fluorescent LCDs, emit significant amounts of blue light. This can interfere with the production of melatonin, the hormone that regulates sleep, and make it difficult to fall asleep. However, OLED displays address this issue by emitting significantly less blue light, in part due to their ability to turn off individual pixels.

What is blue light?

Blue light from monitors refers to the high-energy visible light emitted by the screens of electronic devices, such as computers, tablets, and smartphones. This blue light has short wavelengths and a higher amount of energy compared to other wavelengths of visible light.

Although it plays an important role in regulating our circadian rhythm and keeping us alert during the day, excessive exposure, especially before sleep, can have negative effects on our health.

OLED screens, a solution to mitigate these adverse effects

One of the most notable features of OLED displays is their ability to turn off individual pixels completely. Unlike conventional displays, which require constant backlighting, OLEDs can control the light emitted by each pixel independently. This is why they emit significantly less blue light compared to LED or fluorescent backlit LCD screens.

When an OLED pixel displays black, it turns off, meaning it emits no light, including blue light. Therefore, OLED displays have the advantage of reducing blue light emission in situations where the pixels are displaying black areas. This capability also translates to more vibrant and accurate colors. Since each pixel can emit its own light, colors are represented more sharply and true to life.

Likewise, some blue light is always emitted and to address this, ASUS Lumina OLED displays , which we can find on laptops like the Zenbook S13 OLED , offer blue light reduction modes or color temperature adjustments that allow users to Users further reduce the amount of blue light emitted, especially in low-light environments or at night, to minimize eye fatigue and sleep disruption. In addition, they have the TÜV Rheinland seal, which certifies that they emit 70% less blue light and that they are free of flicker or blinking, a rise and fall of intermittent light that we barely notice, but which is very tiring to the eyes.

As this technology continues to evolve and be integrated into a variety of devices, OLED displays have become the preferred choice for those seeking a more immersive, enjoyable and healthy viewing experience.
