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 LCD displays||Letter and digits only||LCDproc||Display with 20x4 characters|
|Graphic LCD displays||black and white only||GraphLCD||Display with 240x128 pixels|
|Colored TFT displays||Plugin in early beta state||GraphTFT|
Graphic LCD displays are relatively expensive. Therefore some people use the PSone LCD for purposes other than intended.
LCDs are working on the basis of liquid crystals in contrast to VFDs (Vacuum Fluorescent Display) which are working with fluorescent gases and have a greater contrast.
