An on-screen display controller or on-screen display circuit (OSDC or OSD Controller) or just OSD is a digital circuit that provides the functionality needed to create on-screen displays - i.e. a circuit that allows text and low-level graphics to be superimposed onto a TV screen (on top of normal video signal). OSD circuitry is found as discrete chips, built-into some microcontrollers, and most recently incorporated into the main graphics processor. Sometimes discrete chips also incorporate other features such as picture-in-picture (PiP) along with OSD.
