SED1341

CMOS VIDEO – LCD INTERFACE (VLI)

■ DESCRIPTION

The SED1341 is a VLI (video-LCD interface) for converting previously separated video signals, intended for

a CRT display, into signals compatible with dot-matrix liquid-crystal displays (LCDs). When sync and data

separators are added, composite video signals can also be processed. Using the SED1341, a compact LCD

monitor can replace a monochrome CRT display without including additional software or hardware.

The frame-buffer memory controlled by the VLI accurately matches the high-frequency video signals to the

low-frequencyoperationoftheLCDunit.Ascreenalignmentfunctionfortheadjustmentofthedisplayposition

makes it easy to implement an LCD module that is compatible with CRT display.

the SED1341 to interface LCDs with the video outputs of a variety of personal computers (PCs).
