随着投影技术的发展,投影系统已被广泛应用于工业和消费电子领域,为了适应市场对其微型化、高清画面和低功耗的要求,设计以德州仪器的DLP2010芯片组为核心,以FPGA为前端控制器,通过I2C和并行视频图像信号对0.2 in(1 in=25.4 mm)DLP芯片组进行控制及图像的投影显示。该设计可使整个设备体积微型化、能耗低、投影图像清晰,适合穿戴式微投影场景的使用。

With the development of projection technology,projection system is widely used in industrial and consumer electronics fields.In order to meet market requirements for its miniaturization,high definition and low power consumption of the device,the design is based on TI's DLP 2010 chipset,and FPGA is the front-end controller.With the I2C and parallel image signal,the 0.2 inch DLP chipset is controlled and projects the image.The design of entire system makes the device miniature and energy efficiency and could project clear image.Thus,it is suitable for the use of wearable micro-projection scenarios.
