发明名称 PROJECTION-TYPE DISPLAY APPARATUS AND CONTROL METHOD FOR PROJECTION-TYPE DISPLAY APPARATUS AS WELL AS CONTROL PROGRAM FOR PROJECTION-TYPE DISPLAY APPARATUS
摘要 Exemplary embodiments provide a projection-type display apparatus, which can address or realize a reduction in weight and size, a reduction in power consumption, and a reduction in noise, and address or realize a reduction in price, and a control method for the projection-type display apparatus, as well as a control program for the projection-type display apparatus. The projection-type display apparatus includes a solid-state light source that emits light, a mirror device that controls an emitting direction of the incident light to thereby subject the incident light to temporal modulation, and a projecting device that projects the modulated light.
