墨水屏设备的日子，这下真的「好起来」了。
6 月初，海信墨水屏在小红书放出了下一代「海信墨水屏手机」A10 的预热海报，并在 7 月份陆续更新了不少产品细节。虽然根据海信的产品节奏，海信墨水屏 A10 正式发售要到 8 月底。但光是海信现阶段公布的消息，就已经勾起了不少墨水屏爱好者的情绪。
按照海信的预热，这款墨水屏手机以一个极为巧妙的方式，解决了墨水屏手机色彩表现差、刷新率低的问题：在手机背面设计了一个专门的磁吸彩色 LCD 屏幕。
图片来源：小红书虽然雷科技暂时还没拿到海信墨水屏 A10，而且海信墨水屏小红书账号上的宣传图也有着浓烈的 AI 味，但就目前的观察来看，这个磁吸 LCD 屏幕的设计，确实解决了长久以来墨水屏体验和 LCD 体验难以兼得的问题。而站在行业角度来看，在 2026 年，数码爱好者们也早已把「手机副屏」玩出了花。
给手机加「墨水屏」副屏日益流行
雷科技在小红书上搜了一圈，发现现在流行的磁吸墨水屏，多少都带点「手工作业」的味道。
有人买现成的 Android 墨水屏，背面贴一个磁吸环，再套上 3D 打印外壳；动手能力强一些的，会给电子价签加上蓝牙主控和电池，从零开始打造自己的墨水背屏。也有些墨水屏阅读器品牌亲自下场，推出了可以独立运行的电子墨水背屏。但看多几条帖子就会发现，大家似乎也没打算让它做太多事，更多的还是用来提供「情绪价值」：
墨水屏换完画面后几乎不耗电，阳光下也看得清，上传照片后正好可以当作赛博「拍立得」。当然了，也有一些品牌会继续挖掘这些墨水屏的「实用性」，比如阅星曈 X4 就把电子墨水屏阅读器做到了 4.26 英寸的超小体积，让用户能以「更方便」「更护眼」的方式看小说。
从配置上看，阅星曈 X4 的硬件配置可以说相当简陋。但就是这样一款「简陋」的墨水屏产品，在电商平台上也一度卖到断货。不可否认，「卖到断货」和阅星曈 X4 本身的备货量也有一定关系，但从另一个角度讲，这类产品的爆火，其实也标志着我们使用墨水屏产品的方式已经发生了改变。
而最近火起来的 AI Agent，恰好又给它安排了一件新差事。
副屏能成手机 Agent 的新载体吗？
前段时间，雷科技体验了来自 OPPO 的「电子吧唧」OPPO Bubble。当时，我对 OPPO Bubble 给出了「功能有限，但前途无量」的评价，指出 OPPO Bubble 这类产品现阶段只能依靠 IP 展示、自拍取景等场景吸引用户。
对于一块需要单独购买的配件来说，能不能体现出「每天高强度使用」的场景和价值，其实比屏幕参数更重要。但就当时的体验来说，较为有限的功能让 OPPO Bubble 难以成为一款高频使用的智能硬件。对于一款需要独立充电的产品（OPPO Bubble 无法通过磁吸反向充电）来说，「低频使用」几乎注定了其「吃灰」的结局。
也正因如此，雷科技认为，功耗更低的电子墨水屏，更适合以背屏的形态成为与智能手机搭配的 AI 交互副屏。
随着 AI Agent 在智能手机赛道全面铺开，手机 AI 的交互也将从现在的「快速交互」慢慢转变为「后台等待」：用户向 Agent 提出任务，Agent 在手机后台干活，三五分钟之后才能看到结果。
很显然，用户没有必要在前台盯着 Agent 干活，只要有个屏幕能显示状态和结果就行。而这恰好就是功耗较低、强调「状态」而不是「动态」显示的 E-ink 屏幕最擅长的事情。
这么一来，墨水屏刷新慢的问题也得以解决：AI Agent 的运行状态原本就不需要每秒更新，几十秒甚至几分钟刷新一次也不是问题；而墨水屏幕只在刷新时耗电，等待时几乎就是零功耗（除了蓝牙通讯模块）。相比需要高频充电的智能眼镜，一块能连续用上几周的磁吸墨水屏，也更符合「吸上就不管」的使用习惯。
也正因如此，在雷科技看来，墨水屏和 AI Agent 这对「跨时代」的组合，堪称「天造地设」。
「无屏 AI」？
其实屏幕反而更重要了
不可否认的是，这两年也有不少 AI 硬件开始走向「无屏」。在「无屏 AI」时代，专门配备一块为 AI 服务的墨水屏，看起来有些反直觉。但雷科技认为，所谓的「无屏 AI」时代，并不意味着屏幕会消失。
在 AI Agent 爆发之前，屏幕既要显示内容，也要承担设备交互的任务；到了 AI Agent 时代，用户把需求说清楚，后面的操作就可以交给 Agent。至于它调用了哪些 App、在多少个页面之间跳转，大多数时候我们并不关心。这种交互方式的改变，确实在一定程度上减少了我们通过屏幕完成「输入」的场景。
但「无屏」的 AI 依旧需要一个显示工作状态的输出设备，在 X 上，不少用户甚至开始用智能音箱或「AI 红绿灯」来提示 AI 的工作进度和状况。但就交互体验而言，语音不适合持续播报任务进度；震动和提示灯只能告诉用户「有变化」，说不清到底发生了什么。
换句话说，即使来到了 AI Agent 时代，屏幕作为视觉交互的核心渠道，其信息输出效率依然无可替代。
因此，无屏 AI 硬件越多，屏幕反而越有可能从设备本体中被拆出来，变成可以在不同场景间移动的独立显示设备。手机负责下达任务和查看完整结果，眼镜、耳机负责随时唤醒 AI Agent，磁吸墨水屏则统一显示 Agent 的运行状态。这种分工，在我看来才是 AI Agent 时代各智能设备最合理的联动模式。
从这个角度看，海信 A10 把 LCD 从墨水屏手机的机身中独立出来，数码爱好者把 E-ink 吸回普通手机背面，两种看似「互相矛盾」的做法，其实都证明了同一个观点：我们对屏幕的需求没有消失，只是屏幕需要显示什么发生了变化。
只能说，即使失去了 Kindle 这个领路人，中国的墨水屏行业，依旧能找到属于自己的路。

The days of e-paper devices are truly “looking up” now.
In early June, Hisense e-paper released a teaser poster for the next-generation “Hisense e-paper phone,” the A10, on Xiaohongshu, followed by updates on product details throughout July. Although the full release is expected at the end of August according to Hisense’s schedule, the information already shared by Hisense has sparked excitement among e-paper enthusiasts.
As teased by Hisense, this e-paper phone features a clever design to overcome common issues such as poor color reproduction and low refresh rates: a magnetic LCD screen is attached to the back of the device.

While Lei Tech has not yet received the Hisense A10 for testing, and the promotional images on Hisense’s Xiaohongshu account show clear signs of AI-assisted rendering, the concept of a magnetic LCD screen successfully addresses the long-standing trade-off between e-paper’s simplicity and LCD’s versatility. From an industry perspective, 2026 marks a year where tech enthusiasts have become adept at integrating “secondary screens” into their phones.
The Rise of Magnetic E-Paper Backscreens
A quick search on Xiaohongshu reveals that the current trend in magnetic e-paper accessories is heavily driven by DIY modifications.
People are buying off-the-shelf Android e-readers, adding magnetic rings to the back, and fitting them into 3D-printed cases. More tech-savvy users are taking it a step further by adding Bluetooth controllers and batteries to electronic price tags, effectively building their own custom e-paper backscreens from scratch. Even some established e-reader brands are entering the market with standalone e-paper backscreens. However, the most common use case seems to be providing “emotional value” rather than strict utility — users love turning these screens into digital photo albums that are viewable in direct sunlight.

There are, of course, brands looking to maximize the practicality of these devices. For example, the Yueshuitong X4 utilizes an ultra-compact 4.26-inch form factor to promote e-book reading as a more convenient and eye-friendly alternative to scrolling on a smartphone.
Despite its relatively modest hardware specifications, the Yueshuitong X4 has proven to be a popular item, selling out in online stores. While the limited stock availability likely played a role in this, the success of the product signifies a shift in how we perceive and use e-paper devices — they are no longer just dedicated readers, but versatile display interfaces. This shift is further accelerated by the recent boom in AI Agent technology.
Can Backscreens Become the New Interface for AI Agents?
Having recently reviewed OPPO’s “electronic bobblehead,” the OPPO Bubble, I concluded that the device, while charming, has limited functionality but great potential. Currently, the OPPO Bubble relies heavily on displaying animated IP characters and acting as a selfie viewfinder to attract users.
For a standalone accessory, the key to success lies in demonstrating high-frequency, daily use scenarios. However, the current feature set of the OPPO Bubble fails to justify the need for a separate charging cable and frequent use. Consequently, it is likely to suffer the fate of many gadgets — being left unused and collecting dust.

This is where e-paper shines. With its extremely low power consumption, an e-paper screen can be magnetically attached to the back of a phone and left there indefinitely. It is the ideal candidate to serve as the visual output for AI Agents.
As AI Agents become more integrated into our daily lives, the interaction model will shift from “immediate feedback” to “background processing.” Users will send requests to the agent and receive notifications minutes later when the task is complete.
Naturally, a user doesn’t want to stare at an empty loading screen while waiting for an analysis to finish. An e-paper backscreen is perfect for this: it can display the status of the task (e.g., “Analyzing report…” or a progress bar) without draining the battery or requiring constant attention. Unlike smartwatches or glasses, which require frequent charging, a low-power e-paper display can last for weeks on a single charge.
Thus, the combination of e-paper and AI Agents is a match made in tech heaven.
The Rise of “Screenless AI” and the Rebirth of Screens
While there is a strong trend towards “screenless” AI interfaces, suggesting that screens themselves are becoming obsolete, I believe this is a misinterpretation of the data.
Before the era of AI Agents, screens were multifunctional: they displayed content and served as the primary interface for user input (touchscreens). With AI Agents, the input method has changed — users speak or type a command, and the agent does the rest. We no longer need to visually track the agent opening apps or jumping between windows.
That said, the output remains critical. Even if devices are “screenless,” some visual indicator of the AI’s status is required. Currently, we see this in the form of simple LEDs or smartphone notifications. However, these mediums lack the richness necessary to convey complex information. Consequently, screens are not disappearing; they are being redistributed.

In a future-proof design, the main phone screen would be used for complex data visualization (reading the full report), while a detachable e-paper backscreen would handle the “status board” (showing the agent is processing the request). This modular approach allows users to tailor their setup based on their specific needs — a concept perfectly illustrated by the user-friendly magnetic attachments seen in the images above.
In conclusion, as the e-reader market matures, the future of e-paper lies not in replacing smartphones, but in enhancing them as a dedicated output device for the AI-powered future.
Before AI Agents exploded, screens had to display content and handle device interaction. Now, in the AI Agent era, users just state their needs—the rest is handled by the Agent. We don’t care which apps are called or how many pages are jumped; we just want results. This change reduces the need for constant screen input, but doesn’t eliminate the screen’s role entirely.
Even without a screen, AI systems still need to communicate status. Some users on X are using smart speakers or “AI traffic lights” to signal progress. But voice isn’t good for detailed updates, and lights/vibrations only signal change rather than explain what happened. So visual feedback remains critical.
Screens are irreplaceable for efficient information output. In AI Agent mode, the screen may serve more as a readout of success/failure or data visualization than as an input tool. But it’s still essential.

As AI agents become more capable, we’ll see more devices without screens—but that makes the *existing* screens more valuable. Imagine your phone controls the Agent, your glasses trigger it, and a magnetic e-ink display shows its status. This modular approach makes sense.
Hisense A10 split LCD from e-ink, while hobbyists attach e-ink to smartphones—both show we’re not giving up on screens, just reshaping their function. We don’t need them for typing, but we do for understanding results.
Without Kindle leading the way, Chinese e-ink companies are finding new niches. The future isn’t no-screen, but multi-functional, context-aware displays that bridge the gap between raw data and user understanding.
