DlLP470TP 0.47 4k uhd dmd (PICO)

The Chinese 4K UST market has seen explosive growth since the beginning of the year, with many more products, especially in the low end segment using the TI .47 XPR chipset, due to be released in the coming months. Many of them make incredible brightness claims without providing any accurate specifications to substantiate the claims. One particular piece of information lacking is the type of chipset used.

But now we may have a clue. The attached was taken from a write up of one of these products claiming 2500 lumens. But according to TI, the pico chipset is meant for low power devices and has limited brightness capacity. So how is this possible? Or is it?

Anyone with inside knowledge care to share?

Here's official specs taken from a soon to be released model claiming 3000 lumens, although it remains unclear whether the higher output rating is achieved by using a colour wheel with a white segment at the expense of colouur accuracy.

3000 lumens may be at the high end of the brightness scale in the CONSUMER segment but is not considered high brightness in the greater projector market. Consider conference/classroom projectors or large venue projectors where lumen ratings can easily reach 5 figures.

And, yes, every one of the higher brightness 4K home models (747, UHD51ALV, TK800M) use a white segment in their color wheels to extract extra lumens. This almost always comes at the expense of color accuracy/saturation vs an RGBRGB model.

What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...

I forgot to mention, the pico DMD is practically identical to the existing .47” DMD with the exception of a smaller die (smaller footprint and less heat dissipation). The pico isn’t new— it’s been listed on the TI site for well over a year now.

if only the outside world knew how many NEW pj's are coming out locally they'll be blown away & some of them have really good quality, that's why a few guys here took the brave leap to order those locally available even though menus are in chinese. Almost most internet content vendor has released their own versions like jd, dangbei, tencent but some are mostly ODM either from appo or inovel that's why most look similar.

find something similar here?

so TI will be milking the 0.47 even more in the XPR arena. is it even possible to have a 0.47DMD @ TRUE 4K or a bigger chip is a must?

check out this 60K Lumens pj from appotronics, not sure what DMD its using
