Short-focus technology not only fits the practical needs of small-sized units, but also increases the flexibility of projection. Last year's hottest projection products were none other than laser TVs equipped with ultra-short technology. Coupled with the laser light source brightness, color, long life and other advantages, the laser television allows projection to replace TV full of confidence. Although all conditions of laser television are good, it is very difficult for consumers to accept the high price.
