description The invention discloses double-path laser projection equipment, which comprises a double-laser group, a double-optical-path channel, a double-DMD imaging chip, a double-channel laser lens and a signal control and processing module. Common laser projection or projection equipment completes picture display through a single DMD, and due to the fact that the DMD bears temperature and is limited by the technology, high-pixel and high-brightness display under a large screen cannot be completed. According to the double-path laser projection equipment provided by the invention, video and image signals are divided into a left half part and a right half part through an FPGA/DSP or other CPUs, the left half part and the right half part are respectively sent to a DLP1 chip and a DLP2 chip, the two chips respectively control two DMDs to complete image imaging of the left half part and the right half part, and images of the left half part and the right half part are transmitted in a double-channel lens and are synthesized
