Why are there no new projector phones in 2020?
In a highly competitive environment, the success of any electronic device on the market directly depends on its functionality. Therefore, all modern household appliances, including refrigerators, robot vacuum cleaners, washing machines, coffee machines, etc, support a wide range of different smart functions. This trend manifests itself most clearly in the segment of high-tech smartphones. For example, camera phones and gaming smartphones have been successfully competing in the market for a long time. The improvement of laser LEDs has allowed engineers to actively use them as light sources for projectors. Of course, companies did not miss the opportunity to expand the functionality of phones with this option. As a result, at CES 2009 Samsung introduced the first W7900 smartphone with projector. Subsequently, the company introduced Galaxy Beam 1 (15 ANSI lm at 640 x 360 resolution) in 2012, and Beam 2 (20 ANSI lm at 800 x 480 resolution) in 2014. Unfortunately, their very low brightness and resolution could not provide acceptable quality. The development of micro-electrical mechanical system (MEMS) technology has given a powerful impetus to this direction. As known, laser scanning technology for projection and 3D sensing was developed by the American MicroVision company. This technology uses scanning mirrors of MEMS, red, green, blue, and infrared lasers, optics and electronics to project or capture images. Read the full article
