Title: Anode voltage adjusting circuit for cathode ray tube
Inventor: NAKAGAWA MITSUHISA
IPC: H04N3/26
Filed: 1989-04-17
Abstract: PURPOSE:To prevent the fluctuation of a focus point by superposing an output of an adjusting circuit of a differential constitution to a low voltage side terminal for an anode voltage of a secondary side winding. CONSTITUTION:When a power supply voltage +B supplied to a primary side of a fly-back transformer 12 generates an error against a reference voltage value, an anode voltage supplied to a CRT 10 generates an error against a voltage value which is set in the beginning. Therefore, in the case a focus adjustment of the CRT 10 comes off from a set state in the beginning and becomes incorrect, the power supply voltage dependency of resolution is eliminated by canceling an error portion generated in the anode voltage by the influence of an error portion of the power supply voltage +B supplied to the primary side. In such a way, the anode voltage adjusted in the beginning is always in a correct state and an optimum focus point of the CRT 10 can be obtained easily.
