What does OHP mean?
OverHead Projector (OHP) is a device that is used to display images on to a wall or screen by means of an overhead mirror. The images or contents which need to be projected are first made on a transparent flexible material, typically cellulose acetate. The transparent sheet is often called OHP sheet, which is placed on the OHP to display the contents on the sheet.
