摘要： PURPOSE:To prevent deterioration in the image quality due to ununiformed shape of picture elements by controlling a drive voltage applied to a line cathode being a beam source generating an electron beam and giving corresponding adjustment data to a memory so as to eliminate the dispersion in a beam spot to be caused. CONSTITUTION:A counter 102a uses a clock 101a being a vertical synchronizing signal as an initializing signal and counts number of clocks 101b being 11H periodic signals till another clock 101a is received again. Then a counter 102b counts number of horizontal synchronizing signal clocks 101c by using the clock 101b as an initializing signal. A memory 103 receiving the count by the counter 102a as a high-order address and the count by the counter 102b as a low-order address provides an output of an adjustment value corresponding to a scanning line. The adjustment value is given to a D/A converter 104, from which an analog signal is given to an amplifier 105 and then the voltage of the analog signal is amplified to a degree to control a drive voltage of the line cathode. Thus, a vertical diameter of a beam spot is controlled by giving the adjustment address data to the memory.

A reset means for detecting the abnormal pulse between the circuit 3 and the Braun tube 1, and resetting the display device is arranged. Then the delay time of the circuit 3 is made longer than the reset time of the display device. Thus, the abnormal pulse from the Braun tube 1 can be made to reach the circuit parts 2 after a reset operation is completed, so that the circuit malfunction is prevented and also the deterioration and the destruction of the parts due to the superimposition of an abnormal voltage or the abnormal pulse on an operation voltage are prevented.
