ABSTRACT:
A projector with a flexible sheet to reduce electromagnetic interference (EMI). The projector has an upper case, a lower case, an optical engine and at least a flexible sheet. The upper case is electrically grounded and connected to the lower case. The optical engine is disposed in the lower case and located between the upper case and the lower case. The flexible sheet is fixed on the optical engine and contacts the upper case to release the noise to ground and reduce the electromagnetic interference (EMI) from the optical engine.
