These aberrations are still present on the Galaxy S23 Ultra, visible at medium brightness and increasing in severity for lower brightness levels. ![]() This is often seen as a ghosting trail when swiping around a black background, sometimes called "purple-" or "black smear." The advent of high-refresh-rate OLEDs significantly reduced its intensity, but not entirely. When displaying true black, OLEDs on smartphones have typically had slow response times when transitioning through dark gray. What's different here is in pixel design, as Apple's blue subpixels drop steeper in luminance at an angle so that the optical drive between the three subpixels is more equivalent when displaying white. The Samsung Galaxy S23 Ultra, on the other hand, still takes on a cool tint when viewed at moderate angles. With the iPhone 14 Pro, its viewing angles have been significantly improved, and there's almost zero color shift in all the models I've seen. May vary per unit.īeyond those technicalities, there are other minor visual differences I could point out between the Galaxy S23 Ultra and the iPhone 14 Pro OLED panels. Samsung's latest model still shows a slight blue tint when viewed at an angle. This could be due to a shortage of supply, or perhaps they're currently exclusive to Apple's process. My interpretation is that the Galaxy S23 Ultra is using a red and green material stack that's newer than the iPhone 14 Pro's, but older blue materials. What this means is that each OLED belonging to the three phones is an independent set of luminescent materials, so they can't be categorized with the usual generational identifiers (like Samsung Display's "M11" or "M12"). Lastly, the iPhone 14 Pro shares the same old red emitter as the Galaxy S22+, while the S23 Ultra uses a different set with a slightly lower wavelength. The green emitter of the Galaxy S23 Ultra shares the same peak wavelength as the iPhone 14 Pro, but the former is broader, which means it doesn't get as saturated as the iPhone, but it should be a bit more efficient. Although it's difficult to tell from the chart scale, the iPhone 14 Pro's blue emitter is slightly different from the other two phones, being a tiny bit narrower and lower in peak wavelength. It houses a screen that has Samsung Display's newest generation of OLED, with peak brightness values up to 30% greater than the Galaxy S22 Ultra and S23 Ultra. So, here are the 2 methods to turn on or off grayscale mode on Galaxy phones.Things get a bit more interesting when considering the iPhone 14 Pro spectrum. When you use it during the day, it can help you stay focused on your work or other important aspects of your life, reducing the temptation to constantly check your phone. This means your phone’s battery will last longer, and you won’t have to charge it as often.Īlso, by turning all your videos to greyscale, you might find it easier to resist the urge to stay glued to your phone late into the night and actually get some much-needed sleep. Secondly, it’s a real game-changer for those with vision issues like color blindness, making phone usage more comfortable for them.įurthermore, when you switch on greyscale mode on a phone that has an OLED screen, it can actually save a lot of battery power. Firstly, it helps people use their phones less, which is good for our eyes and overall well-being. ![]() This handy feature has become quite popular because it serves multiple purposes. Meanwhile, over the past few years, more and more modern smartphones have started to offer a greyscale or monochrome mode. Do you want to know how to turn on or off the monochrome or grayscale mode on your Galaxy phones? This post will show you 2 different ways to enable and disable monochrome mode on Samsung Galaxy phones running One UI 5.1 based on Android 13.
