原标题：基于TOSHIBA TC358779XBG的雷射微投影机方案

　　雷射微投影机方案让您只要直接插上有TYPE-C的手机，不用安装任何APP就可以放大手机输出的影像与孩子或同事观看照片、影片与简报。在户外露营也可以利用手机播放影片与照片，拉近彼此距离。

　　轻薄小巧是雷射微投影方案最与众不同的地方，高度9.5mm颠覆了传统投影笨重的形象。投影没有距离限制在关灯状况下2米可达100吋，可以在任何地方皆能保持清晰投影，让您不必受限于只能找投影幕。

　　Overview

　　The HDMI-RX to MIPI DSI-TX is a bridge device that converts HDMI® stream to MIPI® DSI while providing de-interlacing and auto-scaling features.

　　TC358779XBG share the same 80-pin package as that of TC358749XBG.
