The LED factory has actively cut into the niche market, and there is a progress in Longda biometrics

In order to get rid of the red sea of lighting backlighting and so on, the LED factory has actively cut into the niche market, in which "biometric identification" has become a trend. Longda sights 2D and 3D sensing, and the infrared light module can be used to monitor the camera, the pen, and even the UAV. The recent cooperation with the customer's smart doorbell can deliver images in real time, and visitors to the door of the family can be seen thousands of miles away.

IPhone X launched 3D face recognition last year, although there is no LED factory in the supply chain, but crystal and billions of light are actively seeking relevant orders. Among them, Longda has quietly invested in "biometrics" outside the mobile phone, such as the monitoring camera of the intelligent building, which provides the infrared light module, installed in the mall, can identify the face and body, and display the age and sex of the consumer on the screen.

Longda said biometric identification is a potential market, widely used, from mobile phones, car radar, industrial automation to UAVs, and the role of LED vendors is indispensable.

For example, the 3D sensor of the mobile phone has two red spots in the camera lens, which is the VCSEL (vertical resonant cavity laser) module for the wavelength of 800-900 nanometers. The light points are hit on the face and turn to the quantized value, then the system is used to judge whether it is the owner of the cell phone.

VCSEL, regardless of the resonant cavity structure at the bottom of the semiconductor or the chip end, is similar to that of LED, and the platform factory with epitaxial technology is easy to cross.

Biometrics is also used in intelligent buildings. In the near future, Longda and customers have launched "smart doorbell" and built three high-power infrared light modules in the night or dark environment, and can also take visitors' images. The owner of the house through the mobile phone App, even in Europe on a business trip, the door bell can see the visitor who is.

Longda has also developed a new biometric scheme with a large number of power plants to deliver Microsoft certification. Microsoft's Windows Hello supports three identification of face, fingerprints, and iris, so the infrared light module of the pen must be within 75-100 cm distance, taking into account the projection of different angles. Longda has the advantage of vertical integration, which is designed by itself from chip, board, lens and so on. The final module is smaller and more efficient.

It is reported that Longda March revenue of 920 million yuan (NTD, the same below), the monthly increase of 21.5%. The first quarter revenue was 2 billion 650 million yuan, and the quarterly decrease was 1.9%. Although biometrics is full of imagination, it now accounts for only about 5% of its revenue. This year, the capital expenditure was about 2 billion yuan, half of the new factories in mainland China and half of the new enterprises, including VCSEL. The legal person thinks, VCSEL will be in the second half of this year small volume trial production, the first quarter will make a significant contribution to revenue in the first quarter of next year.
