The Future Of Pico Projectors

摘要

Computers of the 1960s (Fig. 1) were large, slow, and power hungry. However, the introduction of the integrated circuit (IC) changed all that. Displays, though, have not seen similar progress: Today's low-power displays have small, low-resolution images, such as cell-phone displays, while high-information-content displays such as LCD TVs are large and power hungry. But, as we are just beginning to see, the combination of new high-brightness LEDs with IC-based micro-display imagers (Fig. 2) in pico projectors may launch displays on a trajectory matching that followed by IC-based computers.
