Why are smart projectors so expensive? Where is the price expensive?

Smart projectors are expensive on DMD chips. This chip is a patented chip developed and produced by an American company called Texas Instruments. Only their family can do it, which is a complete monopoly, accounting for nearly 50% of the cost of the projector, and the rest is the optical machine and light source. Therefore, in the field of projectors, there is a saying that "the bottom is big enough to crush people", which means that the larger the chip size, the higher the cost and the better the projection quality. For example, the newx7d of Big Eye Orange is equipped with a 0.47-inch DMD chip, and the projection resolution reaches the original resolution of 1080P, so it has become the well-deserved king of intelligent projectors in the price range of 3,000 yuan. Others, such as Nut O 1S and Petain's latest U 1, are only 0.23 inches, and the picture quality is much better than newx7d.
