并非所有120Hz智能手机显示器都是平等的 - 这就是为什么

90Hz and 120Hz panels are the latest trend in the smartphone world but don’t be fooled by the marketing taglines. Not every 120Hz phone offers the same显示质量, features, and certainly not the same电池寿命。There’s a lot that goes into a great display besides just the frame rate on the spec sheet.

For starters, we’ve already seen phones sporting high refresh displays disable these modes out of the box or hamper their implementation for the sake of battery life.我在看着你谷歌和三星。There are also questions to answer about the quality of 120Hz displays that are quickly making their way to the mid-range tier.Are they really comparable to those offered by flagship handsets?

我们在下面的文章中介绍了出色的现代智能手机显示器中的一些内容OnePlus 8 Pro‘s industry-leading display. However, there’s much more to the story and a lot of hype to kill and myths to debunk surrounding the 120Hz display trend.

120Hz不是质量保证

虽然90Hz和120Hz显示器从某些应用程序和用户界面（UI）的元素（UI）的元素看起来更顺畅，但高刷新率本身并不是显示质量的迹象。颜色准确性，伽马校正和白平衡都与刷新率无关，并且对大多数内容的外观产生了更大的影响。虽然120Hz看起来更光滑，但图片和视频仍然可以在校准较差的显示屏上看起来过于饱和或不饱和。

With this in mind, individual display models from different manufacturers all look quite different, even though they may have the same refresh rate. For example, cheaper displays are more likely to have noticeable issues and poor color calibration. Be cautious of affordable phones boasting high refresh rate panels as they could be attempting to distract from other issues. On the flip side, flagship tier phone displays can go above and beyond the factory color calibration, as OnePlus showcased with the 8 Pro. This is why it’s still worth paying attention to traditional display quality metrics and not just the refresh rate.

传统的60Hz显示器至少在颜色准确性方面看起来仍然比120Hz面板更好。将60Hz旗舰板与便宜的120Hz显示器进行比较时，尤其如此。总体质量绝对比稍微流畅的感觉用户界面更重要。此外，仅仅因为显示屏具有90或120Hz功能并不意味着大多数应用程序和内容实际上都充分利用它。

Apps, content, and bob体育提现Android matter

不仅显示各种设备之间的质量，而且高刷新率内容的可用性也可能有所不同。如果毕竟从未使用，那么拥有带有120Hz显示屏的手机没有什么意义，因此这是必不可少的。

应用程序或游戏的帧速率不仅取决于基础硬件，还取决于应用程序编码为渲染和Android的方式的方式。bob体育提现Google has published insights在刷新率上显示与Android上的内容一起工作的程度。bob体育提现值得注意的第一点是，帧速率受到Android编舞家控制的渲染时间的限制。bob体育提现120Hz显示器仅在GPU绘制帧的框架之间仅具有8.3ms。某些应用程序和游戏以显示屏的V-Sync刷新速率渲染，因此它们可以以全帧速率运行。但是，其他人只是花费太长的时间来渲染或具有较慢的更新速度的自定义渲染管道，因此它们根本无法达到120Hz。取而代之的是，游戏可能会持续到90、60、45甚至30fps。

这里的关键要点是，仅仅是因为手机具有120Hz显示屏，这实际上并不意味着所有应用程序都以120Hz运行。具有更大处理能力的手机更有可能达到延迟较低的高帧速率目标，尽管某些应用程序甚至可能针对特定平台进行了优化。

通过一次使用多个应用程序和UI元素，这种情况更加复杂。Google指出，120Hz显示器非常适合查看24、30、45和60fps的内容，而无需审查，因为这些速率很容易被120分开。在120Hz显示屏上播放24fps视频，避免了3：2下拉algorithm required by a 60Hz display, for example. However, conflicts can occur between software, such as a low frame rate video and high frame rate UI. At which point bob体育提现Android has to step in and pick a frame rate, which can result in judder and/or a fallback to the standard 60Hz.

有一个新的setFramerate APIbob体育提现Android 11that helps to find the optimal frame rate for multiple apps running at once. However, current devices have to make do with a preference setting that can lead to conflicts. Ultimately, applications and games can influence the refresh rate but the final decision is made by the platform. Expect next year’s bob体育提现Android 11 phones to handle mixed refresh rate content better than current models.

总体而言，每个应用程序都不太可能达到非常高的帧速率。取而代之的是，Anbob体育提现droid动态切换帧速率以最佳匹配您当前使用的应用程序。但是，即使这可能取决于制造商的实施。

Display processors are a differentiator

If that wasn’t convoluted enough, devices can also add in their own display processing layer to upscale or remove judder outside of the standard bob体育提现Android framework.Processing power is important here, as some effects can be energy-intensive.Dedicated display processors (DPU) can run these tasks more efficiently.这是正确的，yet another processor在您的智能手机内！

Qualcomm’s Snapdragon processorsinclude display and visual processors as part of its Adreno GPU pipeline.These handle video decoding as well as graphics rendering, and the application processor can also run additional display processing software.例如，Pixelworks, a company specializing in display enhancement technology, leverages the Snapdragon 865 to run its Soft Iris calibration and features like tone-mapping and SDR to HDR on the OnePlus 8 series.Other SoCs have their own display processing units as well, but mid-range and lower-end chips don’t have the hardware to run higher-end features efficiently.例如，Snapdragon 765G仅支持120Hz至FHD+，而865可以在QHD+分辨率下管理144Hz。

Complex display features run more efficiently on dedicated processors. These include Pixelworks’ Iris5 and Arm’sMali-D77或者D71，尽管这些提供了不同的功能。例如，IRIS 5能够进行MEMC视频帧速率升级和删除。即使该应用程序本地以较低的帧速率运行，因此，即使该应用程序运行较低，因此进行缩放和插值视频，游戏和其他应用程序也可以帮助提高平滑度。高级显示处理器不仅带来新功能，而且还可以改善能源消耗，这是渴望渴望的120Hz展示的非常重要的考虑因素。

额外的功能和处理选项可以帮助将标准的高刷新率显示到更加一致，平滑的体验。包括高端显示处理器还可以帮助您进行功耗，从而使您始终保持120Hz模式。这是一个隐藏的区别，但重要的是。

并非所有的120Hz显示器都相等

High frame rate displays are certainly nice to have, but there’s much more to overall display quality than just the hertz. Standard display quality metrics still apply and a 90 or 120Hz label doesn’t automatically mean great colors or gamma. That said, 120Hz panels can certainly look excellent, especially if the phone has the software and processing power for enhanced calibration and tone mapping features.

It’s also worth researching what, if any, high refresh rate and other display features ship with a device. A dedicated processor powering enhanced features can be the difference between smoother content and all-day battery life, and a sub-par 120Hz experience. Not forgetting that newer apps and bob体育提现Android 11 will help increase the range of scenarios where high refresh rates are enabled.

这就是为什么所有120Hz智能手机都不相同的原因。
