Abstract
The present invention relates to a multi-frequency display system and method for providing sharpness enhancement. The system comprises a sharpness enhancement circuit that is configured to receive a first and a second input video signal, where the first input video signal operates at a first frequency, and the second input video signal operates at a second frequency. The system further comprises a controller circuit coupled to the sharpness enhancement circuit, that is configured to generate a first sharpness enhancement signal corresponding to the first frequency and a second sharpness enhancement signal corresponding to the second frequency. The sharpness enhancement circuit generates a first control signal in response to the first input video signal and the first enhancement signal, and the sharpness enhancement circuit generates a second control signal based on the second input video signal and the second enhancement signal. An electron gun coupled to the sharpness enhancement circuit is configured to provide an first image having a predetermined sharpness level at the first frequency based on the first control signal. The electron gun also provides a second image having the predetermined sharpness level at the second frequency based on the second control signal.
