Optical module and processing method thereof

The invention discloses an optical module and a processing method thereof, and the processing method comprises the following steps: providing a module main body and a plurality of optical microstructures, transferring and installing each optical microstructure to a corresponding target position on the module main body according to a preset angle, and obtaining a first optical module prototype; detecting and correcting the inclination angles of the plurality of optical microstructures on the first optical module prototype in the Z-axis direction to obtain a second optical module prototype; and carrying out brightness index detection and correction on the plurality of optical microstructures on the second optical module prototype to obtain a target optical module. According to the technical scheme, the optical display effect of the optical module can be ensured, and alignment deviation between the optical microstructures and module pixels due to the fact that the optical module obtained through processing is af
