You will find projectors claiming 1080p resolution at a very wide price range on the market, no matter online or in a walk-in shop. Actually, they should be different due to the different sizes of DMD. So what are the differences between 1080p resolution with 0.23, 0.33, 0.47 DMD?
1. 0.23DMD, 0.33DMD, 0.47DMD chips
Simply put, the different numbers in front of the DMD chip represent different sizes. The chip sizes commonly used in projectors are 0.23 inches, 0.33 inches and 0.47 inches.
The 0.23DMD chip can project 960*540 pixels, and the native resolution is 480p;
The 0.33DMD chip can project 1280*720 pixels, and the native resolution is 720P;
The 0.47DMD chip can project 1920*1080 pixels, and the native resolution is 1080P.
2. 1080p difference between 0.23DMD, 0.33DMD, and 0.47DMD chips
When we buy a projector, we may find that whether it is a 0.23DMD chip, a 0.33DMD chip or a 0.47DMD chip, the resolution of the merchants may be 1080p. Is there any difference between the three? Of course not, we must first know that these three chips of different sizes, as mentioned above, have different native resolutions. So how did the 0.23DMD chip with a native resolution of 480p and a 0.33DMD chip with a native resolution of 720p achieve 1080p?
Here we will first briefly understand the XPR jitter technology of Texas Instruments. XPR dithering technology is to make the chip move by half a pixel, and a frame of picture is divided into multiple projections, using the phenomenon of visual persistence to superimpose. Products using 0.23DMD chips and 0.33DMD chips are added to the TSP optical module, and the number of pixels is doubled through high-speed dithering of the micromirror, and the number of pixels is close to 1080P. This is the 1080p resolution advertised by the merchant.
But the actual imaging pixels are determined by the physical resolution. Therefore, only products using 0.47DMD chips are truly 1080p resolution. Neither the 0.23DMD nor the 0.33DMD chip is close to 1080p in physical quantity, and the displayed picture is not as good as the true 1080p of the 0.47DMD chip in terms of clarity and color.
So when we buy a projector, if we want a true 1080p picture effect, we must look for products that use a 0.47DMD chip, and you can check the projector's parameter table.
That's all there is to the difference between 1080p resolutions of 0.23, 0.33, 0.47 DMD. You may be interested in the relation between chip and resolution, you can click to view. For more information, refer to the Projector forum.
