As we await the launch of the OnePlus 9 Series, I’d like to talk to you today about our next generation of display technology, soon to make its debut on our newest ultra-premium flagship OnePlus 9 Pro. A DisplayMate A+ rating, QHD+ resolution, 10-bit color depth with a billion colors, HDR10+ certification and Automatic Color Temperature Adjustment – these are the kinds of things you’ve come to expect from our displays. This time, we believe we’ve delivered on all that and more.

​

In 2016, when most players in the industry were still using LCD panels, we became one of the first to make the switch to OLED panels on the OnePlus 3. Then, in 2019, we launched the OnePlus 7 Pro featuring a 90Hz Fluid Display with QHD+ resolution, inspiring others to follow suit and begin an era of high refresh rate displays.

On the OnePlus 9 Pro, we engineered Fluid Display 2.0, introducing a new generation of advanced mobile displays by integrating LTPO backplane technology and revolutionary touch response technology.

A new generation in display technology

It is challenging for phones to maintain both a high resolution and high refresh rate at the same time without impacting battery life. At OnePlus, we have worked hard to continuously improve the viewing experience of OLED panels while extending battery life. Now, with the OnePlus 9 Pro, we’ve switched to a revolutionary display technology that can do just that.

With LTPO (Low-Temperature Polycrystalline Oxide) technology, a special backplane designed to reduce power consumption despite a higher refresh rate, we believe the OnePlus 9 Pro will offer the best of both worlds. A key breakthrough in display technology, LTPO dynamically adapts the refresh rate from 120Hz all the way down to 1Hz – lower than anyone in the industry – based on your content. The display intelligently and effectively scales power requirements resulting in power consumption being significantly reduced at lower refresh rates.

​

How it works
LTPO combines LTPS and Oxide TFTs (in this case IGZO – Indium Gallium Zinc Oxide). With LTPO, the switching circuits use the LTPS side while the driving TFTs use the IGZO material effectively solving the power leakage issue of LTPS OLEDs while keeping all the positives intact. Combined with special display enhancements and an adaptive refresh rate, the OnePlus 9 Pro’s display now uses up to 50% less power while continuously delivering a super smooth 120 Hz viewing experience when needed.


120 Hz just got smarter

By leveraging the technology of LTPO, we were able to achieve this breakthrough in display technology with the OnePlus 9 Pro with Smart 120 Hz. The technology automatically switches to the most appropriate refresh rate according to the operation being performed on the display – from as low as 1 Hz for operations like viewing photos to as high as 120 Hz for intense gaming and video. The OnePlus 9 Pro is the first phone to achieve an adaptive refresh rate from 120Hz all the way down to 1Hz. That means that, for static content, the display can refresh as low as only once per second, thus greatly reducing power consumption.

​

Up to 6X faster syncing speed

But, LTPO is just the half of it. The OnePlus 9 Pro’s display brings a new level of touch response to gaming with up to 6x faster syncing speed between the display and the processor. This reduces the latency in games by 25-30ms, meaning your gaming controls are noticeably more responsive than other devices.

How it works
Every time you touch a smartphone display, the phone runs through a series of processes in order to render a response on the display itself. On the OnePlus 9 Pro, we were able to significantly streamline this process through Hyper Touch, shortening the display response time. According to our internal tests, when playing games with Hyper Touch support, the OnePlus 9 Pro feels noticeably more responsive than other 120Hz displays.

That means when you’re battling in certain games, the OnePlus 9 Pro’s display gives you better reaction times for an edge over your competition. For example, when engaging in intense firefight in PUBG MOBILE, the OnePlus 9 Pro will be able to bring up that rifle scope slightly quicker compared to other smartphones giving you that window of opportunity to outgun your opponents. Right out of the box, Hyper Touch will support League of Legends, Call of Duty Mobile, PUBG and Brawl Stars, and gradually come to include other titles in the future.

We've been working hard over the past few generations of OnePlus flagships to give you a fast and smooth display experience. Now, the OnePlus 9 Pro Fluid Display 2.0 takes smoothness beyond anything you’ve experienced before.
