摘要

In a projection-type display device 1, a display control device 2 that controls a first DMD 50 and a second DMD 70 is composed by comprising an interface circuit 2 a, a mirror device drive circuit 2 b for controlling the driving of the micromirrors of second DMD 50, a mirror device drive circuit 2 c for controlling the driving of the micromirrors of second DMD 70, a CPU 2 d that controls computations and the entire system based on a control program, a ROM 2 e that contains the control program of CPU 2 d and so forth in a predefined area, and a RAM 2 f for containing data read from ROM 2 e and so forth and computation results required for the computation process of CPU 2 d.
