Cathode output scaling |
摘要 |
<p>The present invention relates a method and system for scaling the output of an electron gun in a cathode ray tube. The system comprises an electron gun located in the cathode ray tube and a memory configured to store an offset value representative of a difference between a maximum output level and an unadjusted output level of the electron gun. The system further comprises a processor coupled to the memory. The processor generates a first signal representative of an input voltage corresponding to the unadjusted output level of the electron gun, and the processor generates an offset signal representative of the offset. A summing circuit is coupled between the processor and the electron gun, which combines the first and the offset signals to provide a scaled signal. The electron gun receives the scaled signal and generates an optimized output based on the scaled signal. The scaling technique may also be applied to a second and a third electron guns. <IMAGE></p> |
