Diode array monochromatic projection imaging device

The invention relates to a diode array monochromatic projection imaging device which comprises a diode integrated circuit board, a light emitting diode, a connecting line, a driving control board, and an optical lens group. According to the diode integrated circuit board, a plurality of light emitting diodes are integrated into a PCB, and an M*N array is formed. The driving control board is used for decoding a picture to be projected, the binary value of each point of the array is obtained, and the on and off states of the light emitting diode corresponding to each point is controlled according to a value. The light emitting diode array transmits display picture information to the optical lens group, and the imaging is carried out in an imaging surface. By using the structure of the invention, the picture displayed on the diode integrated circuit board is subjected to the integrated imaging of the lens group, and the imaging precision can be improved significantly. 本发明涉及种二极管阵列单色投影成像装置，包括二极管集成电路板、发光二极管、连接线、驱动控
