New Patent Allows Virtual Reality Helmet to Prevent Screen Damage from Sunlight

A recently published patent by HUAWEI TECHNOLOGIES CO., titled "Control Method for Wearable Device, and Electronic Device" (patent number: US20240134148A1), introduces an innovative solution for preventing damage to the screen of a virtual reality (VR) helmet caused by sunlight. This breakthrough addresses a critical issue faced by VR users and offers a game-changing solution.

The problem at hand is that when a VR helmet is not being worn, the optical lens in the device is exposed to the environment. Ambient light, particularly focused near the human eyes, enters the optical imaging module and reaches the screen after passing through the lens group. This concentration of light energy at the screen can lead to impairment, or even total failure, of the display. Conventional solutions involve the addition of a polarization device to reduce the intensity of ambient light focused on the screen. However, this approach often leads to a reduction in display brightness and requires high assembly precision.

The newly patented method offers a unique control mechanism for wearable gadgets, specifically VR helmets, that overcomes these challenges. A wearable gadget equipped with this technology can detect its wearing status and increase the diopter of the optical lens group when it is in the unworn state. By doing so, the wearable gadget increases the size of the light spot formed by focusing ambient light on the screen through the lens. This disperses the energy of the light, effectively preventing screen damage from sunlight.

One of the remarkable advantages of this solution is that it does not require any structural modifications to existing wearable gadgets. The gadget controlling the VR helmet adjusts the diopter to its maximum, ensuring that light is dispersed on the screen to its fullest extent, thus protecting it from harmful sunburn. Furthermore, the gadget intelligently enables the sunscreen mode only when it determines, within a specified duration, that the wearable gadget remains in the unworn state. This dynamic decision-making reduces power consumption by avoiding frequent enabling and disabling of the sunscreen mode.

The successful implementation of this patented technology would revolutionize the VR experience. Users would no longer have to worry about sunlight damaging their VR helmet screens. They can enjoy immersive virtual worlds without any compromise in display brightness or quality. Whether it is exploring virtual landscapes, gaming, or engaging in virtual training, this breakthrough ensures that users can fully embrace the virtual reality without any concerns about screen damage caused by sunlight.

While this patent showcases significant promise, it is important to note that being a patent does not guarantee its appearance in the market. Industrial applications, technical limitations, or other factors could impact the commercial availability of this innovation.

In conclusion, Huawei's groundbreaking patent offers a compelling solution to prevent screen damage in VR helmets caused by sunlight. With this innovation, the future of VR looks brighter and more immersive, allowing users to explore captivating virtual environments without compromising the visual experience.
