Huawei has launched the MateBook Pro S in China, a laptop featuring a specialized "Smart Shield" screen designed to block side-viewers. The device operates on the Linux-based HarmonyOS and utilizes a custom ARM-based processor.
The two-layer pixel design of the Smart Shield Privacy Screen
The core innovation of the Huawei MateBook Pro S is its 3.1K-resolution OLED display, which incorporates a "Smart Shield" system. According to the report,this technology utilizes a two-layer pixel design where a second set of pixels activates specifically when the privacy mode is engaged. This ensures that the screen remains visible to the user directly in front of the device while appearing dim or entirely black to those viewing from a steep angle.
Users have two ways to trigger this privacy state. The Huawei MateBook Pro S can use its integrated webcam to detect the presence of onlookers and prompt the user via a popup, or the user can simply flick a physical switch to toggle the mode. While third-party plastic privacy fliters exist, the report notes that Huawei's integrated solution aims to provide a more seamless experience, though it may result in reduced brightness and clarity when active.
A 1,600-nit HDR display and an 8,000 yuan price tag
Beyond its privacy capabilities, the Huawei MateBook Pro S boasts high-end visual specifications, including a peak brightness of 1,600 nits in HDR mode. This level of luminance is designed for high-fidelity content consumption, although the source suggests that this peak brightess likely drops significantly once the Smart Shield privacy mode is enabled.
The device is currently positioned as a premium offering in the Chinese market, with a retail price of approximately 8,000 Chinese yuan, which converts to roughly $1,185. This pricing places the MateBook Pro S in direct competition with other high-end professional ultrabooks, though its unique hardware features distinguish it from standard OLED laptops.
From Samsung subways to Starbucks spreadsheets
The move toward integrated privacy screens reflects a broader trend in mobile hardware to combat "visual hacking" in public spaces. As the source reported, similar privacy features have appeared in Samsung's top-end smartphones, primarily serving to prevent strangers in crowded environments, such as subway cars, from viewing a user's screen.
However, the application of this technology to a laptop like the Huawei MateBook Pro S is arguably more critical. Professionals working in airports, cafes , or shared workspaces often handle sensitive spreadsheets and passwords that are far more vulnerable on a large laptop screen than on a handheld device. By integrating this into the hardware, Huawei is addressing a persistent pain point for remote workers who find traditional adhesive filters cumbersome or visually degrading.
The Kirin XE90 chip and the HarmonyOS barrier
Despite the appaling hardware, the Huawei MateBook Pro S remains inaccessible to most global consumers due to its internal architecture. The laptop is powered by the HiSilicon Kirin XE90, a 9-core, 14-thread ARM-based chip. Because it runs on the Linux-based HarmonyOS rather than Windows, the device lacks the software ecosystem required for most Western enterprise users.
This creates several open questions regarding the device's actual utility. It remains unclear how the Kirin XE90 performs under heavy professional workloads compared to x86 processors from Intel or AMD. Furthermore, the source does not specify the exact percentage of brightness loss when the privacy screen is active, leaving users to wonder if the display remains usable in bright outdoor environments while in privacy mode.
