After having invested a large number of televisions and our smartphones, the OLED display is invited in the Asus ZenBook 13. Unlike LCD screens which combine liquid crystal cells backlit by LEDs, Oled panels (for Organic Light-Emitting Diode) are self-emitting and therefore do not need an external device to illuminate them. screen pixels (Full LED backlight, Edge LED, Mini-LED, etc.). This screen technology is based on a simple principle: organic light-emitting diodes consist of a superposition of several organic semiconductor layers between two electrodes, one of which (at least) is transparent. When current flows, they can display 1.07 billion shades and pure blacks (corresponding to the extinction of a pixel). Finally, each pixel of an OLED panel is made up of three sub-pixels allowing precise control of brightness and tint.
Minimum thickness and infinite contrast
The first advantage of OLED is the absence of backlighting (diodes producing their own light). As a result, much thinner screens (2mm) and extra wide viewing angles are obtained. Furthermore, removing the backlight results in significant energy savings. Asus ZenBooks achieve 20 hours of video playback on a small footprint battery. For their part, LCDs, with their backlighting system, do not offer a uniform distribution of light, which forces the viewer to be in front of the screen in order to have the best possible image.
Second advantage, the OLED has an almost infinite contrast with deep blacks. To render this color, the pixel is simply turned off. Another related advantage is that they offer faithful colors even in low light. In the case of LCDs, this is attenuation, a bit like looking at a candle flame through sunglasses.
Third advantage, OLED screens break records in terms of response time (time it takes for a black pixel to go white or vice versa), the Asus ZenBook 13 never exceeds 0.2 milliseconds. For comparison, LCDs are between 0.8 and 10 milliseconds.
Finally, OLED screens protect themselves from marking due to the prolonged display of a still image. When the screen has been inactive for 30 minutes, the system Asus OLED Care Automatically launches a kind of screen saver to protect and extend the life of the panel.
Exceptional colors for the pros …
The Asus Zenbook 13 OLEDs have obtained various certifications that guarantee rich, vivid and faithful hues in all circumstances. Pantone certification (a company specializing in color charts and colorimetry, a true benchmark in the world of printing and graphic designers) guarantees that the colors displayed are identical to those of reality. Model makers, designers and individuals will be able to retouch their photos on Zenbook 13 OLED without any unpleasant surprises. Combined with software like Lightroom or Photoshop, ZenBook OLED displays transcend a photo library by helping correct chromatic aberrations or exposure issues. In addition, the HDR coverage rate of these OLED panels reaches 70%, while the LCD competition struggles to exceed 46%.
Professional and amateur videographers will be happy to learn that the Zenbook OLED panel offers unprecedented color spaces on an ultraportable. Their scores reach 100% of DCI-P3, the digital cinema color gamut, and 133% of sRGB, the default color space offered for digital devices. In addition, editing is more precise and setting special effects is easier, thanks to the ZenBook 13 OLED’s record response time (0.2 milliseconds). Particularly wide color spaces that will also benefit image hunters.
… And the general public!
As curious as it may seem, office uses are also favored thanks to reduced eye fatigue. This is because OLED displays emit up to 70% less blue light than their LCD counterparts. The scrolling and manipulation of text on the screen also benefit from great fluidity. The ZenBook 13s indeed have exceptional display precision in real time thanks to the 6,220,800 self-illuminated sub-pixels of their OLED panel.
OLED technology also benefits computer entertainment. Viewing movies stored on the Zenbook 13 hard drive or via Internet streaming services such as Netflix or OCS takes advantage of the improvements mentioned above, in particular to benefit from a better contrast and thus better discern the details in the dark zones of the videos. Video game aficionados will rediscover their favorite titles with faithful colors and blur-free animations, respecting the work of development studios. Gamers will appreciate even more the total absence of latency during the games. If there is latency, it will be more to be found on the side of the quality of their Internet connection or the power of their graphics card.
