The reflective display element includes a reflective display surface. The prism device includes first and second prisms. The first prism includes first, second and third surfaces. The second prism includes fourth, fifth and sixth surfaces. A stray light beam is incident into the first prism, passes through the third surface and then exits the first prism, then the stray light beam is incident into the second prism through the fourth surface, and then the stray light beam is reflected by the fifth surface and then exits the second prism. The light absorbing element is disposed on a transmission path of the stray light beam exiting the second prism. A projection device including the imaging module is also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projection device and imaging module having light absorbing element thereof","description":"An imaging module includes a reflective display element, a prism device and a light absorbing element.
