The Research of Micro-Display was presented. The Micro-Display, as the main part, supported the 1280×1024 high definition to display the color text and picture,with the 12^x optical zoom system before the OLED display chip plan. The Micro-Display eyesight can been changed to meet different demands with handle machine, and supported the digital vedio input with changing the picture parameters by serial communication. All the part were sealed to protecte the optical electricl part from musty. By the test, the performances meet the techniqure demand, and it has the advantage that the volume and weigh are small, and the exit pupile distance is appropriate to display with little aberration,and suitable for the sigle solider launch device application.
