Abstract
The present disclosure provides an optical lens module. By assembling a first lens barrel, an optical folding element and a second lens barrel, the optical lens module can be miniaturized, image quality of the optical lens module in a compact assembly space can be increased, and the size of a light passage opening of a display panel module can be reduced so as to increase consistency of a display area.
