| Interfacing with an analog LCD screen and blanking |

Hello, For a project of mine i need to generate a video display . I know how this works on CRT screens and i'm running the signal through VGA. However , i thought about those older LCD screens that accept a vga input and that accept a regular analog signal . Being more compact , these displays are ideal for me. My question is this : CRT's rely on blanking to move the beam around without drawing to the display . The extra time spent blanked is overscan. But LCD's don't have a beam . what happens when a CRT would usually blank ? Does the LCD simply abstract it , or are any modifications required to the signal? |

Panels of all kinds are still scanned and still have blanking intervals (porches). |
