Displays are mostly used to display channel information, as shown briefly on the OSD after channel switching.
There are basically three display types
|Type||Remark||Needed VDR plugin||Bild|
|Alphanumeric LC-Displays||Letter and digits only||LCDproc||Display with 20x4 characters|
|Graphic LC-Displays||black and white only||GraphLCD||Display mit 240x128 Pixeln|
|Colored TFT-Displays||Plugin in early beta state||GraphTFT|
The graphic LC-Displays are relatively expensive. Therefore some people use the PSone LCD for purposes other than intended.
LCDs are working on the basis of liquid crytals in contrast to VFDs (Vacuum Fluorescent Display) which are working with fluorescent gases and have a greater contrast.
