On-screen display
The on-screen display [ ɒnskɹiːn dɪspleɪ ] ( engl. "Display" abbreviated OSD) is an indication that on the current image (for example in a. Television , a computer screen or video goggles ) appears. It is primarily used to display additional information and can also be used to operate a device (e.g. to make settings or to navigate in teletext ; via buttons on the remote controlor on the monitor you can move in the menu). The displaying device does not necessarily have to be the controlled device; for example, user guidance for a connected DVD player can be displayed on the television screen. The OSD is multilingual in modern devices.
Certain text windows controlled by graphic computer applications can also be referred to as OSDs.
advantages
By using part of the high-resolution screen (as opposed to a roughly rasterized display), clearly recognizable pictograms (in color) are available to the OSD . This increases user friendliness and shortens the training period.
The use of OSD technology also saves the installation of other control displays. This can reduce the manufacturing cost.
disadvantage
The OSD always covers part of the actual picture. This can be perceived as annoying, especially if small changes obscure almost the entire picture. Often more than 40% of the entire screen area is covered just for the display of the volume change .
