Fremont, Calif. - Optoma introduced Thursday the PK120 pico-class video projector based on Texas Instruments' new nHD digital micro-mirror device for micro DLP light engines.
The nHD DLP chipset is said to offer higher resolution (16:9, 640 by 360 pixels). The "palm-sized" projector weighs 5 ounces and outputs 18 lumens of brightness from its LED illumination source.
Other improvements include a new file viewer that delivers direct playback of MS Office and PDF files, movies and photos.
It incorporates 2GB of internal memory and has a microSD card slot, allowing for memory expansion up to 32GB.
The PK120 is available now from major retailers at a price of $249.
"The technology and feature set included in the PK120 push it right to the head of its class," said Jon Grodem, Optoma's product and marketing senior director. "It's not only more powerful and versatile, but it's also easier to use."
The new projector is said to deliver improved clarity on text or other black content by creating a smoother image than seen in other pixels.
To improve the PK120's audio capabilities, Optoma has integrated two 0.5-watt speakers into the projector, plus an audio-out port for connecting to external speakers.
A cable adapter is standard with the PK120 for easy connections to PCs and laptops, and other cables are available for connecting to iPods, smartphones, digital cameras or other devices with video output.
Grodem said Optoma also developed a more intuitive user interface for the PK120, supporting PC-free viewing of Office documents. It also adds navigation features, such as zoom and scroll.
Another new pico feature is a dedicated power plug for faster battery recharging.
The PK120 plays common picture and video formats along with office documents directly from files stored internally or on MicroSD cards inserted into the onboard slot.
Supported video formats include H.264 (AVI, MOV, MP4, 3GP); MPEG-4 (AVI, MOV, 3GP, WMV); M-JPEG (AVI, MOV); and Xvid (AVI, WMV). Supported picture formats include JPEG and BMP.
The PK120 measures 4.6 inches long by 2.4 inches wide by 0.8 inches thick. The newly improved LED lamp system is capable of producing up to a 2,000:1 high contrast ratio and enough brightness for users to project images up to 70 inches (diagonal).
The PK120 is powered by an included rechargeable, lithium-ion battery, with up to 90 minutes of run time per charge.
