Laser LEDs helping pico projectors to enter mainstream

Though not very successful, Pico projectors are still hoping for a big comeback in smart phones as well as other portable computing systems. If Pico projector was accepted way of display in mobiles, the laptop should have been just a CPU integrated keyboard with built-in projector and a touch pad. Market has seen smart phones, camcorders with pico projectors, but they are not so successful, at that cost, and due to not so impressive performance of pico projectors and also due to advancement in LCD panels both in technology as well as cost. One of the culprit in the failure of Pico projector was LEDs which were used as light source. They were not reliable, resulting in higher failure rate. The expensive and not so high picture quality producing LED-based pico-projectors could not compete with constantly falling in cost, as well as resolution improving LCD panels. But the Pico projectors are getting renewed now due to the use of lasers instead of LEDs as light source. The MEMS based micro-mirror chips are also now available in small sizes and support Full-HD and feature interfaces such as HDMI. Full HD projectors are now designed for applications such as digital signage, mobile/portable projectors, screenless TVs, control panels, interactive displays, and wearables such as head-mounted displays (HMD). Recently Lenovo has launched a smart phone with laser Pico projector...
