What is OSD?

An on-screen display (OSD) is a control panel on a computer monitor or television

screen that allows you to select viewing options and/or adjust components of the

display, such as brightness, contrast, and horizontal and vertical positioning.

On a computer monitor, an on-screen display is usually activated by buttons on

the bottom of the monitor. As an example, one button may bring up a display of the 

brightness and contrast levels, which may be adjusted by pressing the monitor's up

or down arrow buttons.

On a television screen, an on-screen display can usually be activated either through

buttons on the television set itself or through the remote control. Television on-screen

displays are becoming increasingly complex and interactive. In addition to the visual

calibration options, the on-screen display may allow you to view program information,

search for programs, or put certain channels under parental control.

Now, OSD is used in most RC professional drones, China Topwin has professional
