Abstract
A single chip display system processor in a CRT (Cathode Ray Tube) based display is disclosed, including a display system controller, a horizontal processor, a vertical processor, and optionally, the on screen display (OSD) processor. The horizontal processor, a vertical processor, and the on screen display (OSD) processor are under control by the display system controller. This single chip display system processor also controls some elements of the CRT based display, such as power horizontal deflection circuit, power vertical deflection circuit, video processor, the power video circuit, power supply for the electronics and CRT, and the user front panel. The display system processor encompasses a phase lock loop (PLL) circuit within the horizontal processor that compares incoming horizontal signal with the feedback signal from power horizontal deflection circuit for the purpose of synchronizing incoming video signals to display stable image in the CRT based display system.
