Rapid Improvement of laser LEDs has allowed engineers to use them as light sources for projectors. As a result, the market filled with various ultra-portable pocket projectors. Consumers were enthusiastic about the new product, stimulating the further development of this trend. Today the list of leaders includes AAXA, Miroir, Optoma, Anker, APEMAN. But, of course, this list is far from complete. For example, RIF6 introduced only one, but unprecedentedly popular RIF6 CUBE mini projector, with a size and weight of only 2 inches and 0.36 lbs (136 g). The success of mini projectors in the consumer market has provoked several companies to develop projector smartphones. From 2008 to 2017, Samsung and Sony introduced several of these models. But their very low brightness and resolution could not provide acceptable quality. The development of micro-electrical mechanical system (MEMS) technology by the American MicroVision company gave a powerful new impetus to the development of this direction. In 2018, Blackview and Wireless Mobi Solution, Inc. (WMS) presented Blackview Max 1 and Moviphone (Voga-V) smartphones with an integrated laser projector and MEMS technology. Many experts predicted the success of this direction. But today comparison of buying phone + mini projector vs projector phone provides the radical advantage to purchasing two separate devices in terms of value for money. Read the full article

Laser LEDs has allowed engineers to use them as light sources for projectors. Powerful lamp-based projectors provide high brightness, but require a powerful fan and a large internal volume to cool the lamp. In addition, the fan operation is accompanied by a fairly high noise level up to 70 dB and even higher. The brightness of LED projectors is much lower, but they do not heat up and do not require cooling. This allowed companies to develop miniature projectors. As a result, the first ultra-portable pocket projectors hit the market. Consumers were enthusiastic about the new product. Of course, the companies responded adequately to the high demand by actively developing new mini projectors. Today the list of leaders includes AAXA, Miroir, Optoma, Anker, APEMAN. But, of course, this list is far from complete. For example, RIF6 introduced only one, but unprecedentedly popular RIF6 CUBE mini projector, with a size and weight of only 2 inches and 0.36 lbs (136 g). As a result, the market today offers an abundant range of excellent ultra-portable projectors including, for example, AAXA P7, LG PH30N, etc. Almost all modern mini-projectors use DLP (Digital Light Processing) chip from the American Texas Instruments company. Of course, this technology has some key features that affect the specs of portable models. Specs 1. Dimensions and weight For marketing reasons, some companies sometimes position models weighing a few pounds or more as mini. Read the full article
