Abstract
A COB module of an optical mouse has a controller circuit and optical components of the optical mouse integrated thereon, so as to improve the problem with conventional optical mice that light path shifting tends to occur and improve the imaging definition. By disposing a button and wheel mechanism independently outside the COB module, the optical mouse has significantly improved flexibility in design, lower cost related to design alteration, and relaxed requirements on alignment and correction during production.
