  • NEC NP-PH3501QL 4K Laser projector

    The NEC NP-PH3501QL is a 4K laser phosphor projector with an internal chiller, allowing for an all in one multi laser solution. The projector utilizes direct Red and Blue lasers. Green is achieved by using a second Blue laser to energize a green phosphor. Typical with all Blue Phosphor projectors, red falls short of the P3 color requirement for cinema projectors. P3 is also the minimal color space requirement for HDR source content. NEC's RB laser solution expands the color gamut well beyond P3 getting it closer to REC2020, the color space for HDR. It also solves any color balance issues common to Blue Phosphor projection. That's not all, the additional RED laser helps the projector to deliver a brighter image. In this case, the NP-PH3501QL delivers up to 40,000 center lumens.
    By using green phosphor for the reproduction of green, laser speckle is reduced and no longer visible giving reason R/B laser is a worthy contender worth consideration even for those looking into RGB laser.
    The NP-PH3501QL is a multipurpose projector which includes 2 HDMI 2.0 inputs which can accept a native 4k signal.





    I tested this input using an OPPO UHD Blu-Ray player and several 4k UHD Blu-ray titles. I experienced no HDCP handshake issues, playback was flawless. well done NEC.
    The NP-PH3501QL surprisingly offers several settings and features dedicated to HDR, far more than any other commercial projector and exceeding many consumer projectors that claim HDR ready.  The projector uses one of several lens options that cover a wide range of throw distances, all very high-quality offerings. Lens shift, up, down, left and right have a very wide range of travel. Lens memory is included allowing for multiple aspect ratios at the push of a button.
    Light output can be reduced through an on-screen setting, this feature is very flexible. I measured "native" contrast at minimal light output 1833:1 and at maximum light output 1809:1. These numbers are typical and fall in-line with all commercial projectors delivering very high light output. In addition to the native contrast, the projector offers a "dynamic contrast" feature. You have a choice for content in motion or static images. This feature uses laser dimming to achieve an increase in contrast up to 7500:1 when engaged.
    You would expect a projector delivering 40,000 lumens of light output to be very noisy. To my surprise measurements came in at a respected 50db at 1 meter and 60db with the chiller engaged.
    Spending time with the NEC PH3501QL, I am now a believer in RB laser technology, it is hard to ignore the benefits that far outweigh standard Blue Phosphor projection. NEC may be the first at this light level implementing RB laser along with an internal chiller for an all in one laser solution. The NP-PH3501QL delivers a very bright, smooth analog image with very satisfying color. A job well done, congrats to NEC.

    It is indeed amazing that the lumens is better than blue laser only projectors. Sofar I have only seen platforms lose lumens when moving from B to R+B lightsource.

    Also that claimed 82%+ of SMPTE Rec.2020 colorspace is great for none RGB laser projectors.

    So, how does that black in the demoreel look so deep but shiny black, with the standard sub 2K:1 on off contrast ratio. The dynamic controls must really do their job. How close to the claimed 30K:1 does it get.

    I just found this picture by NEC in an advertorial in a German trade magazine. Sorry for the poor picture, it is either washed out by flash or this semiflashed picture. The cost comparison between Xenon and R+B laser is with the older NC3541L, but the basic configuration should be the same I guess. Though the people at NEC might have done something speccial to get that higher dynamic on-off contrast.

      The NEC NP-PH3501QL shining onto a approximately five meter screen, at its launch during ISE 2018. The demo was repeated for the 2019 show, with the screen and projector at the second half of the large two story NEC booth. This year the screen edge appeared to have a glass-like sheen, but it was hard to tell what its construction was as it hang up high and the (multilayered?) edge was not lit.

            Digitimes in a brief article on Delta building an 8K ecosystem mentioned the company is developing an RG laser source. Most likely an RB Blue+phosphor source like Appotronics is developing for the small Hisense projector.

            Delta is the ODM/OEM behind the large NEC projectors. Those are assembled by DPI, which itself is owned for at least 42% by Delta.

            Delta uses laser light sources to improve the lifespan of its projectors, and it is also developing RGB laser projectors looking to expand the color gamut.<\q>
