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