Hitachi unveils its first LED projector

Hitachi’s Digital Media Division previewed its first LED projector. The new projector employs Hitachi’s newly developed LED optics platform featuring an exclusive crystal-based engine with HLD (High Lumen Density) technology to achieve more than 3,000 lumens brightness and approximately 20,000 hours of expected operating hours without any lamp exchange.

In addition to lower total costs of ownership, Hitachi believes that the new model will offer a significant leap forward in image quality. The company is positioning its LED platform as the core SSL solution for sub 5,000 lumens categories, and plans to rollout multiple models with the LED optics platform beginning in Q1/2016. The company believes LED is a more suitable choice of Solid State Lighting technology because LED is a more common and reliable technology to be used in daily life.

“In creating our first LED projector our goal was to produce something truly different – and better – than previously existing LED technology,” said Mike Morin, Strategic Sales Development Manager. At the core of the projector is the newly developed crystal-based engine with HLD technology. HLD utilises blue LEDs that illuminate into a crystal rod, where the blue light is changed to green and discharged from the rod. This light source operates in tandem with a high-brightness red LED and a high-brightness blue LED with Hitachi’s original high efficient illumination optical system to achieve over 3,000 lumens brightness and a 20,000:1 contrast ratio.

Because of the purity and intensity of the green light from the crystal rod, the RGB colour space is significantly larger especially in the blue and green regions, resulting in far more accurate and lifelike colour reproduction. In addition, thanks to the rapid refresh rate of the HLD design (about ten times faster than the refresh rate of lamp based technology), the convergence of the three LEDs is said to be much better than previous designs, yielding exceptional image sharpness and clarity.
