10.1 Application Information

The DLP9000 DMD is controlled by two DLPC900 controllers. This chipset offers two modes of operation. The first is video mode where the video source is displayed on the DMD. The second is Pattern mode, where the patterns are pre-stored in flash memory and then streamed to the DMD. The allowed DMD pattern rate depends on which mode and bit-depth is selected.

The DLP9000X DMD is controlled by the DLPC910 controller, where the DLPC910 is configured by the program content in the DLPR910. This chipset offers streaming 1-bit binary patterns to the DMD at speeds greater than 61 Gigabits per second (Gbps). The patterns are streamed from an customer designed processor into the DLPC910 LVDS input data interface.

Both the DLP9000 and the DLP9000X provide solutions for many varied applications including structured light,
3-D printing, video projection, and high speed lithography. The DMD is a spatial light modulator, which reflects incoming light from an illumination source to one of two directions, with the primary direction being into a projection or collection optic. Each application is derived primarily from the optical architecture of the system and the format of the data being used.

10.2 Typical Applications

10.2.1 Typical Application using DLP9000

A typical embedded system application using two DLPC900 controllers and a DLP9000 DMD is shown in Figure 17. In this configuration, the DLPC900 controller supports a 24-bit parallel RGB input, typical of LCD interfaces, from an external source or processor. The 24-bit parallel data must be split between a left half and a right half, each half between the two controllers. The external processor must format each half to consist of 1280x1600 plus any horizontal and vertical blanking at half the pixel clock rate. This system configuration supports still and motion video as well as sequential pattern modes. For more information, refer to the DLPC900 digital controller data sheet listed under Related Documentation.

10.2.2 Typical Application Using DLP9000X

Direct-write digital imaging is regularly used in high-end lithography printing. This mask-less technology offers a continuous run of printing by changing the digitally created patterns without stopping the imaging head. Figure 18 shows a system where a DLPC910 digital controller is coupled with the DLP9000X DMD. This system offers an ideal back-end imager that takes in digital images at 2560 x 1600 in resolution to achieve speeds of more than 61 Gbps. For more information, refer to the DLPC910 digital controller data sheet listed under Related Documentation.
