HORIZONTAL SIZA AUTOMATIC CONVERSION CIRCUIT IN DISPLAY APPARATUS

摘要

Multi-corresponding horizontal frequency When operation is displayed for all signals with horizontal frequency of 31.5KHz and 15.75KHz, it detects for each frequency and then can automatically control the horizontal size for the frequency, that is, the constant size regardless of frequency. As an image display device, it can be used as a horizontal deflection circuit that supports not only the current TV video signal but also all video signals corresponding to 31.5KHz such as computer signal (VGA) and game machine.
