Apparatus and method for display synchronisation and display using such apparatus

摘要

The synchronizing signal (I) causes the advance of a counter (22) at the speed of a rapid clock (Fr,20) and an enlarged synchronizing signal (IA) is sent to the display until a comparator (26) detects equality with a keyboard input (23) stored in a memory (25). The enlarged synchronizing signal alters the release timing of line signals received and stored in the display such that sampling of the signal levels is accurate
