在以前，大屏平板的定位总是被人们质疑，原因嘛，自然是相比笔记本电脑便携性并没有太大的提升，同时生产力也跟不上。而如今，在华为这样的品牌的努力之下，随着HarmonyOS 3的赋能，不管是小尺寸平板还是12.6英寸的大屏平板，也拥有了媲美PC级的办公能力，大屏平板的市场瞬间被打开了。如今，华为再接再厉，在发布会上又带来了全新的旗舰新品：华为MatePad Pro 12.6英寸，那么这款平板实际表现如何，今天我们就来看一下。

轻薄外观，质感机身

说实话，在我刚拿到开箱的瞬间，就被这款平板的轻薄所震撼到了。在一款屏幕尺寸达到12.6英寸的设备上还能感受到6.5mm的机身厚度，那种轻薄质感确实非常舒服。

我手里的这个是曜金黑配色，采用了创新的玻纤光学镀转印膜凝霜工艺设计。它在不同光线下的金属光泽还会出现微妙流转，我个人感觉是很舒服的设计，让原本沉闷的黑色变得灵动了起来。而且还有一个好处，就是避免了后盖沾指纹的情况出现。

另外，华为还推出了一个白色款，用的是素皮材质，喜欢素皮温润质感的可以选择。

高清巨屏，细腻显示

来到正面，这款高素质的12.6英寸巨屏冲击力也不小。这是一块OLED原色全面屏，这次的屏幕刷新率也提到了120Hz，整个使用观感会更加丝滑流畅。不止如此，这块屏幕的边框控制也是不错的，在12.6这个尺寸上实现了90%的屏占比，而且还是四边等宽。

在屏幕的显示素质上，华为尤为重视。这块屏幕拥有2560x1600高分辨率，高像素密度高达240 PPI，同时还有10.7亿色显示和P3广色域。采用硬件低蓝光技术，支持1440Hz 高频PWM调光，通过了德国莱茵Full-care Display3.0的所有测试要求。而且为了避免用户在使用不同设备的时候画面出现色差，华为还实现了跨设备呈现一致色彩显示，所以不管是用华为电脑、平板还是手机，看到的都是一致的真实色彩。

还有一个比较有意思的功能，之前在手机上非常火的AOD熄屏显示，也被加入到平板上，个人感觉还挺好玩。

足够大的屏幕加上素质够好的显示效果，真的让我忍不住用它来看电影刷视频。直接外放的话，音质表现也很顶，因为它用的还是八扬声器设计，配合华为专有的低频增强算法，效果更是拉满。所以即使是有音频创作需求，用这款平板也能满足你。

（如今华为视频的媒体内容也非常丰富）

PC应用引擎，高效办公

硬件堆叠得再强，没有好用的系统优化其实体验也会是一塌糊涂。所以华为尤为重视软件生态建设，这款华为MatePad Pro 12.6 英寸所搭载的是全新的鸿蒙3系统，不仅是可以实现和其他鸿蒙设备的高效互联互通，更重要的是华为推出了PC应用引擎技术，可以在HarmonyOS平板上实现PC应用的原生体验。而这在12.6英寸这样的大尺寸上，又能够有这更好的发挥。我这里体验了PC级的WPS，真的和电脑上用起来非常像。

移动端的WPS的最大痛点就在于无法与PC窗口一样展示多窗口，无法快速在多窗口之间切换，无法自由调整窗口的大小，这对于办公效率的影响非常大。而华为就发现了这一痛点，PC级WPS就可以自由开启多窗口，还能实现WPS表格的数据、图表、公式等功能，WPS演示的视图、对象等功能，放开了平板设备的生产力限制。如果外接了键鼠设备，那使用起来会更加得心应手，几乎和PC上无异。

说真的，我的日常移动办公需求主要就是文字处理。就目前的使用情况来看，华为MatePad Pro 12.6 英寸对于我这样的轻度办公需求已经基本满足了。出门带个平板确实要比笔记本更轻松，况且不办公的情况下还能很方便地刷剧看电影，惬意。

搭配手写笔，轻松创作

平板是触控设备，所以还有一个很大的优势，可以搭配手写笔使用。这次华为也推出了全新的HUAWEI M-Pencil（第二代）雪域白，在华为Pencil Engine的赋能下，拥有报点预测、手写套件、双击切换、一笔成型4大能力。手写笔日常可以直接吸附在平板侧边，方便收纳的同时，也可以进行充电。

为了让体验更完美，华为甚至还推出自研的华为笔记应用。在工作和生活中，记录起来更加得心应手，同时编辑功能也很强大，甚至支持利用套索工具图文混选，可以进行选中图文的移动、旋转、复制。

对于有绘画/设计需求的用户来说，华为MatePad Pro 12.6搭配全新的HUAWEI M-Pencil（第二代）雪域白更是好用。可以使用画世界Pro、Zen Brush 3等软件进行创作，书写起来相当顺滑流畅。而且华为还实现了“跨应用取色”，这大大提升了使用便利性。我作为一个绘画小白，尝试了用画世界Pro来作画，发现确实好用。里面的仿生画笔真的让人有一种真实手绘的感觉，而且填充颜色、撤回重做、扭曲调色啥的都方便。

华为平板集大成者，移动办公新选择

作为如今华为最顶级的一款平板设备，华为MatePad Pro 12.6英寸的确是让生产力再度提升。强大的硬件配置配合HarmonyOS 3的赋能，软件生态更为完善；PC级的办公体验也让移动办公能力实现了跨越；HUAWEI M-Pencil（第二代）雪域白配合华为自研的华为笔记应用，日常记录也变得方便快捷。而且搭配画世界Pro这样的软件之后，更是能爆发惊人的创作力。

当然，10050mAh超大电池甚至还有无线快充加持，续航也不会有烦恼。至于超级终端、平行视界、远程PC这些鸿蒙设备中最「基础」的功能，也为整体体验保驾护航。所以如果你需要一台屏幕够大、显示够优秀且生产力强大的平板，那它或许是iPad Pro之外的另一种选择。可以说，华为用创新和技术，重新定义了平板电脑的移动办公体验，也真真正正满足了不同人群的全场景办公和创作的需求。
