Oppo recently held the OPPO INNO DAY 2019 event, where the smartphone maker showcased its Under-Screen Camera (USC) technology for smartphones.

With a focus on removing the notch on smarphones from 2018 since the launch of OPPO Find X, OPPO engineers have been obsessed with giving the optimal, full-screen experience on a smartphone. Displayed to media for the second time (first at Shanghai MWC), the Under-Screen Camera technology provides users with a complete view, an immersive screen and an integrated body. It also enables users to see and capture the entire screen, take photos, use face unlock and make video calls.

As OPPO’s latest under-screen display solution, USC features a customized camera module that captures more light; zoning control is employed on the screen, together with “highly-transparent” material that enhances transmittance of light through the screen.

Besides, through OPPO’s customized algorithm, haze removal algorithm and white balance algorithm, USC can enable complete photography experience and support features like smart beauty mode and photo filers in the future.

At the event, Oppo also showcased the forthcoming OPPO AR Glass, the OPPO 5G CPE and a smart watch.

The VOOC Flash Charging Zone was featuring various versions of Oppo's proprietary charging technology, some commercially available and some forthcoming.

This included 65W SuperVOOC 2.0 Flash Charge which is commercially available in OPPO Reno Ace. This is able to fully charge a 4,000mAh battery in 30 minutes. Charging for just 5 minutes is enough for 2 hours of gaming.

The display featured VOOC 3.0 and upgraded VOOC 4.0, SuperVOOC (as featured on OPPO Find X), and a more recent innovation, the currently unreleased 30W Wireless VOOC Flash Charge. 30W Wireless VOOC provides wireless charging at the speed of wired VOOC flash charging. Within 80 minutes, this flash charger is able to fully charge a 4,000mAh battery.

The 5G Ecosystem Zone showcased OPPO's main announcement, the OPPO 5G CPE. 5G CPE is a brand new connection hub for scenarios such as the smart home and smart office, turning the 5G network into a high-speed Wi-Fi signal. It provides 5G network connectivity for multiple intelligent gadgets and a variety of IoT devices.

Connected to a 5G CPE, OPPO's self-built IoT open platform enables users to interact with smart home devices through Breeno and other interfaces, providing the comfort and convenience of future smart homes.

OPPO AR Glass, OPPO's first AR Smart Glasses provide a new interactive experience through mixed reality applications.

The standalone AR Glasses combine advanced technologies such as TOF depth sensor and SLAM algorithm to enable 3D environment sensing and 3D reconstruction. The full-color high-definition display is made possible by diffractive waveguide technology; the user interface, which comprises gesture recognition and voice recognition, results in an interactive user experience.
