When you connect this Pico Projector to DVD player, colors of the video remains vibrant and closely match the source but when we connect this projector with iPhone, it projects better quality colors than what my iPhone actually does. If you are using Pico Projectors you have to keep your expectations lower at the brightness but the color output is simply outstanding in their case. You can connect this projector with laptop and can emphasize the color and the picture qualities deliver by the Pico Projector.

The main aim of Optoma is to make a high quality Pico Projector that proves to be ideal for showing photos and videos from any devices that has got video output. Pico PK-101 Projector has a resolution of 640 x 480 and it uses LED light source that has an estimated life of 20,000 hours. It contains a fully charged battery that can give 70 minutes of display in high-brightness mode. This Pico Projector comes with a USB power adapter, tripod charger, two batteries, USB cable, 2.5-3.5 mm jack able with volume control and one AV cable.

The best feature of Pico Projector is its vibrant color. Projected image seems to get brighter due to the color saturation in photos and videos. This projector is wallet sized and can be paired with any portable device like cell phone. Together the can make a mobile presentation system. This projector can show your slideshow in the same way as shown by Aiptek Pocket Camera T10 using portable media player or mobile phone. PK 101 does not have an audio output so you have to connect some audio source such as speakers in order to make your projector audible. There is no messing up around connection as there is only one video input in Pico Projectors.

There are many companies that are developing and manufacturing Pico Projectors Some of them are LCoS, Laser-Beam-Steering and DLP. Let’s discuss them in brief.

DLP( Digital Light Processing)- Idea behind creating DLP is to use tiny mirrors that direct the light. Every mirror controls amount of light received by each pixel of the target picture. It uses color wheel between light source and the mirror in order to get perfect color. Color wheel and mirror splits the light in primary colors i.e. red, blue, green and each mirror controls light beam so as to deliver perfect picture as output.

LCOS(Liquid Crystal on Silicon): This projector uses small LCD display to control amount of light that each pixel can get. It uses two basic designs to get colors. One is Color-Filter LCOS that uses 3 subpixels and another is Field-Sequential-Color that uses a faster LCD so you can split image into 3 primary colors and can refresh LCD 3 times

Laser Beam Steering: This projector is a bit different as it creates the image one pixel at a time by using different laser beam. Here you start with three basic colors which are combined and guided using mirrors. You can not notice pixel-by-pixel design if you are scanning the image fast enough.

Basically there are 4 types of projectors. First is stand alone projectors that receive the input using cable and you can not view any image unless you use another device to stream video signal. Next is USB Projector that uses USB for data and power. They are the smallest projectors as they do not contain battery. Third is Media Player projector that includes memory card and can play file directly from the memory card. The last one is Embedded Projector that is embedded inside mobile phone, camera, laptop etc.

“The NP41 and NP61 projectors provide the powerful features required by mobile users while remaining lightweight and cost-effective,” said Rich McPherson, Product Manager at NEC Display Solutions. “Their automatic features deliver the technological innovation expected of NEC products, delivering bright and brilliant images.”

The BrilliantColor technology has 6-segment color wheel and increases the brightness and color saturation significantly, while the AutoSense synchronizes the projectors with the computer signals intuitively, featuring one-touch optimization.
With the ECO Mode technology the lamp life increases up to 40% reaching 3500 hours of operation.

The Digital Light Processing technology used by NEC DLP projectors is a technology using reflective surface made up of thousands of tiny mirrors representing pixels, instead of the 3 LCD glass panels for red, green and blue image components used by LCD projectors. Benefits of DLP projector technology include small construction for mobile use, higher contrast video with deeper black levels, higher contrast ratio, reduced pixels visibility from a specific distance.

NEC NP61 and NEC NP41 will come out next month and in September respectively, with a 2-year warranty, and will be available at $1,399 and $999.

The new products from Sony bring new quality definition for the entry-level projectors’ market.
Sony’s new E-series projectors use the BrightEra 3-LCD technology that offers the unparalleled picture quality, higher brightness and an increased panel life.

Each of the new products brings new features to this industry. The VPL-EX50 is Sony’s first 2500 ANSI lumen model under 3kg weight category and the VPL-EW5 is the first native 1280×800 WXGA projector made by Sony. More than that, the EW5 is HD ready and by using the 1280×800 resolution means it’s clearly designed for following the laptops’ widescreen video sources. With a standby power consume less than 3 watts, VPL-EW5 becomes the lowest power consumption projector in its class.

Among the interfaces incorporated by the E-Series I would mention a second RGB input for connection with more than one computer for VPL-EX50 and the RS232C to control the external device (used by all those three new projectors).
Setting up these projectors becomes an easy job for every user with the “Quick Start” and “Off&Go” technology.

The most affordable projector from Sony’s E-Series is the SVGA VPL-ES5 that offers brightness to 2000 Lumens at a SVGA 800×600 resolution. Even though this product doesn’t take advantage of the BrightEra 3-LCD technology, the low-price could make it a good seller on the projectors’ market.

The E-Series address to business and education projector market and offering the BrightEra 3-LCD technology to consumers could be a smart move made by Sony in this entry-level business.

If you didn’t know about this, just as I wasn’t aware of it, Explay is a company from Israel, and their tiny projector, called Oio and categorized by its creator as a “nano projector”, is a device that may be incorporated in various mobile phones and cameras, as well as laptops and other devices, in the years to come.

Basically, the Oio employs a hybrid laser, combined with a LED light source, to project images on a certain surface. It is battery-operated, child safe, and future products incorporating it will be able to project screen sizes starting at 7 inches, up to 30 inches.

For now, this is more of a prototype than a finished product, but I am sure we’ll get to see it more and more often, in the second half of this year. A PMP with built-in projector, anyone?…

With the same looks and weight, the Optoma EP7155 comes with 2500 Lumens brightness, just like the EP1691, but its Native XGA (1024 x 768) resolution is a bit lower than the EP1691’s WXGA+ (1680 x 1050).

Unfortunately, I wasn’t able to find anything about the pricing, so you should check availability and pricing for your area by visiting the official site, here.
