摘要

A projection display device adopting two digital display panels, by which the maximum brightness, which is the same as that in a exemplary case of adopting three digital display panels, is obtained by using only two digital display panels, is provided. Accordingly, R'/G'/B'/W data obtained by converting R/G/B data using a predetermined algorithm for a four-color sequence system is displayed via an optical engine having two digital display panels, with the same brightness as that when data is displayed using three digital display panels. Hence, the structure of the optical engine can be simplified, and a convergence adjusting point can be reduced.
