Abstract:
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 2a, a mirror device drive circuit 2b for controlling the driving of the micromirrors of second DMD 50, a mirror device drive circuit 2c for controlling the driving of the micromirrors of second DMD 70, a CPU 2d that controls computations and the entire system based on a control program, a ROM 2e that contains the control program of CPU 2d and so forth in a predefined area, and a RAM 2f for containing data read from ROM 2e and so forth and computation results required for the computation process of CPU 2d.
