Samsung's Dynamic AMOLED: More Than a Hand Hole


Samsung Galaxy S10 Plus screen and cameras

The new Samsung Galaxy S10 range marks many firsts for the company. One of the most important first is the launch of the company's new AMOLED dynamic display technology. The panel caught our attention with its Infinity-O cut, but the new Galaxy S10 is much larger than you might think.

Before going into some technical details, let's start with an overview of the panel specifications. The screen reaches a new peak in terms of maximum brightness, offering 1,200 nits of twinkling light for the retina. This represents a 13% increase over the Samsung Galaxy S9 and ensures that viewing outdoors, even in direct sunlight, should not be a problem.

The panel also has a deep contrast ratio of 2,000,000: 1 for blacks and detailed highlights. Samsung measures the highest brightness at the lowest possible that a single LED can produce (without turning it off). This is a boon to the panel's HDR10 + reading support, a first for the mobile industry.

Reproduction of bright and vibrant colors

According to Samsung, Dynamic AMOLED offers a range of colors covering 100% of the DCI-P3 color space. In other words, the panel must offer essentially perfect color reproduction for high quality content, such as movies, which increasingly use this wider color space than the sRGB. Samsung displays have been supporting the DCI-P3 for generations, but this time also with Color Volume 100% certification. This same certification had already been awarded to Samsung's QLED TV line.

To do this, Dynamic AMOLED modifies organic materials in OLEDs (Organic Light Emitting Diodes). The improvement in color reproduction does not come from a modification of the subpixel layout. Dynamic AMOLED retains the red, green and blue pixel structure of the pentile used by Samsung for some time.

In addition to helping to produce a wider color gamut, this new OLED material also improves energy consumption. This is especially important for maintaining the expected life of the battery in phones with an even larger screen. Such as the Samsung Galaxy S10 5G 6.7 inches, for example.

If that's not enough, the panel also supports HDR10 + tone mapping to further improve color accuracy. Tone mapping information is included as metadata for images in some HDR10 + files. Where available, the Samsung Galaxy S10 can read this format for even more beautiful colors. The handset can also record this metadata in its own HDR10 + video files.

Less blue light with comfort screen

Eye strain and blue light are becoming increasingly popular in some circles, and Samsung has also made key improvements. Dynamic AMOLED benefits from Comfort Display technology to reduce blue light and is certified by TUV Rheinland.

To do this, the wavelength of the blue light on the screen has been changed from about 450 mm to about 465 mm (depending on a graph). This eliminates the majority of the blue light from the "danger zone" panel between 415 and 455 mm, which is related to eyestrain. As a result, the blue light emission goes from 11.8% in the Galaxy S8 and S9 to only 6.9% in the Galaxy S10. Samsung also says that it does not have a negative impact on the quality of the image.

The Galaxy S10 continues to include a blue light filtering software option to help you relax in the evening. When this option is enabled, 99% of the blue light is removed from the on-screen image. A soft switch can be found in the quick settings menu in the notification area.

The best Samsung mobile panel to date

The Samsung Galaxy Series has always set the bar high for mobile display technology and the Galaxy S10 series continues this trend. Dynamic AMOLED seems to be the company's best display technology to date, and for many reasons other than the punch hole. By the way, sophisticated laser technology has forced Samsung to completely redesign its production line. How about this for an eye for details?

The Galaxy S10's display also hides a number of interesting and essential features. The ultrasonic fingerprint reader is perhaps the big choice, but I bet you have not noticed that the ambient light sensor is also displayed on the screen, next to the Wi-Fi icon? In fact, the phone's proximity sensor and speakerphone are also hidden by the Dynamic AMOLED panel.

The Samsung Galaxy S10 and its Dynamic AMOLED technology have everything you need to be the best mobile screen ever built. Although the foldable smartphone is also on the horizon, the best of Samsung Display could still be coming.
