Abstract

The device comprises a projection display module is coupled to the control IC for the data projection. The projection display module includes three liquid crystal panels that perform image displays in red, green, and blue, respectively; light emitting sources are employed and positioned in correspondence with the liquid crystal panels, respectively. A prism is used for each display color combination, wherein the liquid crystal panels and the light emitting sources are positioned on the light-incidence side of the side surfaces of the prism. A projection lens is provided on the light emission side of the prism.
