Philips recently announced the PicoPix Max, a premium and relatively large but still portable Android-powered pico projector that features a Full-HD native image, 800 lumens and a battery life of up to 3 hours. Our friend Charbax posted a nice video showing a prototype device, and Philips says on the video that it already sold over 5,000 such projects on IndieGogo!
TrendForce says that smartphone companies are developing 3D sensing capabilities following Apple's iPhone X launch (with its 3D sensor). The company estimates that the market for mobile 3D sensing by infrared laser projectors will grow from $246 million in 2017 to $1.95 billion by 2020.
Current solutions for mobile 3D sensing include structured light and time of flight (ToF). The iPhone X uses structured light with a 30,000 dot IR projector. Time of flight developers include STMicroelectronics, Google/Infineon/PMD and MicroVision.
