In the past, Huawei has published the Patent Wall on the company’s official website. It revealed 729 patents, preserved for various devices including 5G, Wi-Fi, operating systems, cameras, smart cars, and future technologies.
Still, the company is continually adding new patents for various devices and technologies. On 30 March, Huawei has published a new patent for Graphene Field Effect Transistor with the publication number CN110323266B in China.
The patent document describes that graphene field-effect transistor is related to semiconductor technologies. This will helps to inflame the device’s output resistance so that the switching ratio can be increased for a better radiofrequency.
The graphene field-effect transistor consisted of three-terminal or electrodes:
- A primary and secondary gate electrode that acts as the controller
- The first and second gate dielectric layer
- Source or channel layer and drain electrodes
Furthermore, the source layer’s components include AB stacked double-layer graphene or AB stacked multi-layer graphene followed by the primary and secondary gate electrode placed on the opposite side face of the layer.
The first gate electrode contains a plurality of first sub-electrodes and first connecting sub-electrodes arranged at the intervals and extending direction of the first sub-electrodes. The first and the second sub-electrode are used for the vertical electric field perpendicular to the channel layer.
The distance between the source electrode and the drain electrode crosses the projections of the first connecting sub-electrode, and the channel layer on the substrate does not overlap.
To be mentioned, semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits. Such devices have found in wide application because of their compactness, reliability, power efficiency, and low cost.
Aside from this, Huawei has recently registered a new Car key trademark which could bring new functionality for the smart cars. At the same time, the company has published a new patent for the navigation method. This innovation will help to find car parking spaces.
Huawei to bring new VR head mounted technology: Patent
Huawei is working on new a new VR technology, it’ll add more advanced devices to the company’s collection. In this line, the company has released a new patent, which recently gets the approval of the Chinese Intellectual Property Database. It’ll be a lightweight VR head unit and will release the pressure while wearing the device.
As per the information, Huawei applied for a patent entitled “a head-mounted display and virtual reality system” back in March 2019. Now, it has passed the examination phase and the company has published it with the publication number CN111694152B in China on 14 September 2021.
The patent abstract shows, the described head-mounted display will make the users interact with virtual reality. Furthermore, during the time wearing the head unit users won’t feel much pressure and can enjoy the work with more comfort.
Huawei VR Technology Patent Description:
The application describes that the device will have a main head unit module, two magnetic arrangements, and integrated technologies. Furthermore, the first magnet won’t be dependent on the head unit body. Meanwhile, the second magnet structure will be used for opposite forces.
Thus, this magnetic arrangement will provide the head modules a skyward magnetic force. The technology will be in the virtual reality applications that will provide less pressure.
In June 2021 Huawei Headheld and HeadPositioner (VR) have passed Bluetooth SIG certification with model numbers Par-CG013 and Par-CG012 respectively. Both models will work on Bluetooth 5.0. However, the company hasn’t revealed any further information yet.
Huawei Rollable phone meets Gestures navigation, Nice
In the past, we’ve seen a number of new Huawei patents and designs about rollable phones. Compared to the foldable design, the rollable phone extends outwards from within a regular phone size.
However, new patents continue to appear. In the latest edition, LetsGoDigital has found a new rollable phone design that was filed in February 2020 at World Intellectual Property Organization (WIPO). The patent is titled ‘An apparatus and a method for a controllable foldable display with haptic and sound effect’. The 38-page documentation was approved and released on September 2, 2021.
Huawei Rollable Phone with Gestures:
Aside from its design, the new patent has new hand gestures called Freehand Gesture Control. To conduct such controls, a virtual slider is shown on the screen.
The extended display will be accompanied by haptic feedback (screen vibration) and a sound effect. The advantage of this display extension sound compensates for the noise generated during the rolling process.
Not only that, there are plenty of hand movements that users can make to enjoy a seamless gestures movement across this futuristic device. These includes:
- Swipe above to roll in or out
- A movement to the right to unroll or left to retract

Manage Roll Speed:
The gestures are so advanced, they could even allow users to manage the speed of the rollout and roll back-in process detected by the use of the finger count and is detected by a motion sensor or a camera module. This is quite interesting and is surely futuristic to see that happen.
Realistic Concept Video:
Huawei Mate Rollable appears to be a normal smartphone at first sight. But it has the ability to expand into tablet-like big screen size. Unlike the foldable, the rollable smartphone can increase or decrease the area of its display by rolling in and out.
The phone’s front design looks identical to any regular smartphone, yet it can expand to a large tablet at an instance. Unlike a foldable device, the Rollable phone can expand outwards by taking a limited space. Through this mechanism, a 6.5-inch panel can expand to an 11-inch screen.

Huawei publishes multi-screen interactive patent for smart cars
Huawei has shared a new patent multi-screen interactive technology for smart cars. It was applied back on the 26th of April this year and has published with the publication number CN113330395A in China.
The patent entitled “a method, device, terminal equipment, and vehicle for multi-screen interaction” revolves around smart car technology. The method described in the patent uses a high-definition camera and specific gestures to derive multi-screen interaction.
As per the described approach, at first, the camera analyses a pre-defined specific gesture and captures the command. Afterward, the carried content represents on the first display screen in sub-images alongside other sub-images on the screen.
With this projection on the first screen and derived information, the users can easily presume the movement direction of subsequent gestures. After that, the same procedure is followed for the second screen and controls the sub-images presenting on the first display screen.
Thus, the display screen moves according to the gestures. But when the distance between the gestures and system reaches out of range, the sub-images shift on the second display screen and carries out the multi-screen interactive function.
Last week, Huawei published a vehicle braking patent that contains a power recovery control method according to the state of charge of the battery. It’ll help in taking a more precise decision regarding turning on/off the battery recovery so the users won’t have to face a sudden battery back out.
