Galaxy S10 screen deep dive: Dynamic AMOLED, HDR10+, explained Samsung says its new phone screen is the best it's ever made. We parse the tech that makes it possible. ļæ¼ BYĀ DAVID KATZMAIER FEBRUARY 23, 2019 9:30 PM PST LEER EN ESPAƑOL ļæ¼James Martin/CNET The Samsung Galaxy S10Ā has an in-screen fingerprint reader, wireless charging of other devices, three cameras and an actual headphone jack. But its biggest feature is something its owners will be staring into every day: the screen.Ā  Samsung's engineers didn't neglect the new phone's display. All four varieties -- theĀ Galaxy S10,Ā Galaxy S10 Plus,Ā Galaxy S10EĀ andĀ Galaxy S10 5G-- have different-sized versions of "the most beautiful display that the Galaxy family has ever seen," according to Samsung. And in 2019 it busts outĀ more screen tech buzzwordsĀ than ever, each more arcane than the last.

Here's a cheat sheet with Samsung's latest such words use on the S10, and what they mean. I've listed them in order from most- to least-important, as determined by my reading ofĀ Samsung's display deep-dive. Dynamic AMOLED:Ā Samsung's previousĀ phonesĀ used theĀ marketing termĀ Super AMOLED, and so far it's unclear exactly why they switched to Dynamic -- beyond the fact that it figures into HDR and Dynamic tone mapping (see below), and it sounds cool. AMOLED is a real thing though. It stands for active-matrix organic light-emitting diode, and is one of two screen types used in phones today -- the other is LCD (just about every OLED phone screen is active matrix, so just ignore the "AM"). By most measures of image qualityĀ OLED is better than LCD, in part because it can achieve an absolute shade of black, which improvesĀ contrast. Forget "Dynamic" and "AM" then: the OLED nature of the S10's screen will, as always, be the most important contributor to its image quality.Ā Just like with TVs. ļæ¼ 50 PHOTOS Galaxy S10, S10 Plus, S10E: Every camera lens and curve 1,200 nits peak luminance:Ā Nits are aĀ measure of light output, and 1,200 of them is hella bright. High-end LCDĀ TVsĀ can exceed that amount, but even OLED TVs can't. I'm betting Samsung achieves that number for short periods in a tiny portion of the screen, but even so, I expect the S10 to be the brightest OLED phone yet -- which should help not only with HDR video, but more importantly in a phone, visibility in bright sunlight. Samsung's newer OLED phone screens have also been very good at dealing with reflections, another major factor in bright-light performance, and I expect the same from the S10. 100 percent mobile color volume in the DCI-P3 color range:Ā This means the phone should have aĀ wide color gamutĀ for more realistic colors. The P3 color gamut is standard forĀ HDR (high dynamic range)Ā and many new TVs come close to covering it -- the closest I've measured is 99 percent onĀ LG'sĀ OLED models. 100 percent color volume refers to covering that gamut at every brightness level, something I don't even measure in TVs. In my visual tests differences in color volume have only been visible in the most extreme colors. Paired with a "0.4 Just Noticeable Color Difference (JNCD) score," inĀ DisplayMate'sĀ tests, I expect the S10's colors to be extremely accurate and realistic in the best screen mode(s). Blue-light emission of 7 percent:Excessive blue light from screensĀ can keep you awakeĀ -- by signaling the brain to stop producing melatonin -- andĀ may even contribute to blindnessaccording to one report (here's our explainer).

Yes, for example, the Glory 30 Pro used an OLED screen and launched the OLED e-book mode. In this mode, the display of the screen turned into a black and white effect similar to the ink screen of an e-book. Combined with the color temperature optimization and automatic brightness curve adjustment, the screen in the e-book mode displayed a simulation effect like paper and ink, which could effectively reduce visual fatigue. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Arduino has had success in agricultural applications. Farmers have used it to monitor soil moisture. By inserting moisture sensors connected to Arduino into the soil, they can get real - time data. This helps them decide when to water the plants, leading to more efficient water usage and better crop yields.

The LCD TV could be used to watch the TV station's content for free through the Digital Television Terrestrial Broadcasting (DTL). The LCD TV came with a terrestrial wave reception function, so it only needed an external antenna to watch free TV programs. This method was suitable for LCD televisions after 2015. In addition, you can also watch free TV programs by installing live TV programs or using specific TV applications. These applications provided live and on-demand functions, and could be installed on smart televisions for free. The specific software name and download method could be obtained through relevant searches.
