This new DMD has no higher density, therefor no smaller mirrors and therefor is not to enable native 4K DMD DLP projector. As I initally read the announcement to read that TI had doubled the 3310's diagonal to the standard 0.65"-0.67". As that would double the width and height, quadrupling the surface area. lading me to conject: This might spell the advance of 'True 4K' at more affordable end-user prices. As now start to be announced for the 0.67" 4.15 million mirror DMD plus optical pixel shift TI branded XPR Technology.

The news seems to be an integrated shifting mechanism on the DMD itself.

Of course these pico sized DMDs till now have been (severely) limited in brightness, due to heat concerns and other design issues like etendue.

As brands and developers have been eagerly awaiting a solution that will allow them to create smaller form factor products integrating 1080p projection displays, Texas Instruments announced its DLP Pico 0.33-inch full-HD chipset. Consisting of the DLP3310 digital micromirror device (DMD) and DLPC3437 controller, this is the industry's smallest 1080p display chip solution with the highest brightness capabilities in the 0.3-inch imager class. This latest DLP offering continues TI's commitment to enabling smaller form factors, superior image quality and high system efficiency for customers designing and integrating pico displays. For more information, visit www.ti.com/dlp3310.

With the 0.33-inch chipset, developers can create a myriad of compact, portable display applications, such as mobile smart TVs, battery-operated pico projectors, smart home projection displays, signage and industrial solutions.

Key features and benefits of the 0.33-inch full-HD chipset:

Small form factor 1080p: The fast switching speed of the DMD enables each mirror to display two distinct and unique pixels on screen during every frame. This DLP solution delivers 1080p resolution to the screen along with the industry's highest brightness capability for its size class, enabling a powerful new combination for developers of compact display products.

The pitch is the same as the DLP660TE DMD (5.4 – Micron Micromirror Pitch), so the density is the same, so the pixel array can not be 1920x1080, so it must add a shifting mechanism. Intriguing how the DMD will do this itself, no more seperate optical actuator required?

Add it uses a diagionally orientated mirror array, that in the past made it hard to establish the nominal spatial resolution.

Crisp images and video: Proven DLP technology delivers high color fidelity (up to 16M colors) for vibrant, beautiful images.
Power efficiency: This latest DLP chipset offers efficiency to meet the growing demand of battery powered devices adding display capability
TI collaborates with the most extensive ecosystem of pico optical engine manufacturers in the industry. This offers developers a path to production-ready optical engines, which helps reduce design time and gets customers' innovative products to market faster. Manufacturers planning to offer an optical module utilizing DLP3310 include Shenzhen Anhua Optoelectronics Technology Co. Ltd, Coretronic Corporation, DigitalOptics Co. Ltd, Ongine Technology, Young Optics, Inc. and others.

The 0.33-inch full-HD chipset and the associated components1 will be available in 2H17.

The key words are 'on the screen'

3310: "Displays Full-HD 1920 × 1080 Pixels on the Screen"

Resolution 1080p (1920 x 1080)   
Array Size (Pixels) 1920 x 1080 (pixels on screen)

660TE: "Displays 4K Ultra High Definition (UHD) 3840 x 2160 Pixels on the Screen"

Resolution 4K UHD (3840x2160)   
Array Size (Pixels) 2716x1528 

So what is the array size for the 3310? TI is being unclear on this. For the 660TE TI is clearly listing the mirror array size, not so for the 3310. But pitch is pitch, so comparing the datasheets, both DMDs have the same 5.4 Micron Micromirror Pitch, so the same density.So the 3310 does not have 1920x1080. fully functional mirrors, plus an border of partial functional mirrors set to off to create a clear edge for the light hitting the DMD. But not so for the 3310.

The same density would mean it has about one fourth of the 4.15 million mirrors of the 660TE, not 1080P. So no direct route to 0.67" native 4K DMDs.
