Projection type display apparatus
2013
The present invention relates to a projection type display apparatus that can realize a wide-width color reproduction. The color separating and composing prism used by the projection type display apparatus includes: a first prism that has a first two color coated surface which can resolve and reflect a first light from illumination light as well as make the first light incidents toward a display element of a first reflection; a second prism that has a second two color coated surface which can resolve and reflect a second flight from illumination light as well as make a second light incidents toward the display element of a second reflection; a third prism that can make a third light and a forth light pass and incident toward the display element of a third reflection. In addition, the synchronizing controls includes a light control mechanism that can make the third light and the forth light shining in the way of time division and the actions that control the display element of the third reflection in synchronization with the shining of the third light and the forth light.
