TI reveals new, teensy projector chip

BERLIN–Gadgets such as cameras, portable game consoles, and mobile phones that have tiny digital projectors are still a relative rarity, but Texas Instruments hopes a new chip will help change that.

The company unveiled a new DLP Pico chip for such devices here at the IFA electronics show, a model called the nHD that’s about the size of a raisin. It can be used to project images with a resolution of 640×360 pixels, TI said.

The new model features a better contrast ratio of 1000:1 for darker blacks, a richer color gamut, and lower power consumption, according to TI.

Pico DLP customers include Dell and Samsung. DLP technology is also available in more conventional projectors, but its flagship use is in digital cinema. DLP cinema chips are used in 19,000 digital movie screens, 10,000 of them capable of showing 3D movies and 117 of them used for the larger-format IMAX.
