The best phones with built in projector on the market 2020 Overview

Functionality has long been a prerequisite for the successful competition of any modern consumer electronics. Therefore, companies are constantly expanding it with smart options and innovative technologies. Gaming smartphones and camera phones perfectly exemplify this trend. Rapid advancement of laser LEDs opened up new possibilities for projector developers who began to actively use them as light sources. Miniature size, long life (20,000-30,000 hours vs 6,000 for traditional lamps), and low heat generation allowed engineers to develop mini projectors. The latter factor has become especially important, allowing companies to abandon powerful fans for cooling traditional UHP (Ultra High Efficiency) mercury lamps. As a result, the modern market offers a huge number of different mini-, pico- and pocket ultra-portable projectors. Of course, phone developers have not missed new opportunities by developing phones with a built-in projector. In particular, at CES 2009 Samsung introduced the first smartphone W7900 with a projector. Subsequently, the company developed Galaxy Beam 1 (15 ANSI lumens at 640 x 360) in 2012 and Beam 2 (20 ANSI lumens at 800 x 480) in 2014. Over the next few years, Sony offered the Sony MP-CL1, CL1A and MP-CD1 with this option. Unfortunately, low image quality due to low brightness has become a decisive factor in limiting their popularity. Read the full article

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
