Here is the translated and reformatted article in English without HTML tags: --- In 2019, Only a Few Manufacturers Continued to Launch 3D Sensing Smartphones Xiaomi has gradually released information about its new smartphone, Xiaomi 9, and has started generating hype. The triple-camera system and ultra-high pixel camera will be the main selling points of Xiaomi 9. However, it does not continue the 3D sensing design of its predecessor, and Xiaomi has stated that the benefits of the TOF solution are currently not significant enough to urgently adopt 3D sensing. On the other hand, Honor, which just launched its V20 smartphone equipped with a TOF solution at the end of 2018, holds a different view on this matter. The difference between Xiaomi and Honor is more about their perspectives on 3D sensing modules than the TOF solution itself. Although the iPhone led the way in introducing 3D sensing, causing many brands to follow suit by launching phones with 3D sensing features, these manufacturers also weighed the benefits that 3D sensing functions could bring. From a cost perspective alone, the 3D sensing module costs at least about , and additional space is needed to accommodate the module, which affects the design of a full-screen display. This puts a significant burden on smartphone products. In terms of benefits, biometric functions can be replaced by fingerprint recognition and other solutions, and AR functionality is still underdeveloped. Therefore, companies like Xiaomi have naturally chosen to focus on the technology without consistently adopting it. Other manufacturers, considering the future potential of AR functionality, have released 3D sensing smartphones to create an environment suitable for AR application development, aiming for a competitive advantage in the AR industry in the future. In other words, these manufacturers see the development potential of 3D sensing and are willing to invest at this stage. However, it can be expected that only a few manufacturers will adopt this strategy, leading to a decrease in the popularity of 3D sensing in 2019. Only a few companies like Apple and Huawei will continue to release related products, and the penetration rate of 3D sensing will slow down. Most of the penetration rate will come from iPhone products, and it is estimated to only reach 12.3% in 2019. 3D Sensing Penetration Rate and Market Value in Smartphones from 2016 to 2020 Source: Topology Research Institute TOF Lens Modules Won't Become the Market Focus Until 2020 Regarding the 3D sensing solutions adopted by manufacturers, there are two options: structured light and TOF. However, since facial recognition functionality can be replaced by other features like fingerprint recognition, and due to technical barriers and patent restrictions, manufacturers other than Apple are less willing to attempt structured light. Instead, they are choosing TOF solutions, which is why TOF solutions have gradually gained more attention. Since TOF solutions are not suitable for close-range 3D sensing and can be interfered with by light reflection, they are mainly focused on AR applications and gesture control functions. As a result, manufacturers will not rapidly adopt TOF-based 3D sensing before the application content matures. Even Apple, which has been the most active in the development of 3D sensing, will wait until 2020 to equip its iPhones with TOF camera modules. This is partly to wait for better-performing sensing components and partly because Apple needs more time to lay out its plans in the AR industry. Therefore, in 2019, smartphone manufacturers will focus more on multi-lens setups, high-pixel cameras, under-display fingerprint recognition, and foldable designs. While TOF solutions may attract attention, they will not become the primary focus of smartphone products in 2019. It will only be at the end of 2019 when manufacturers start looking for new topics, and with the 2020 iPhone expected to adopt TOF-based 3D sensing, that TOF lens modules will heat up in discussion and penetration rates will rise to 20%.
