Title: Cathode-ray tube display device
Inventor: NISHIDA RIYOUZOU
IPC: H04N3/28
Filed: 1980-05-27
Abstract: PURPOSE:To increase the brightness of a cathode-ray tube by dividing and allotting a TV signal to an electron gun, which uses many cold electron discharging bodies in an array, through connected delay circuits and gates successively, and by scanning for a specific period. CONSTITUTION:A video signal (a) sent from an image pickup tube P is amplified A and sent to signal delay circuits D1-D3 to obtain signals (a')-(a''') delayed by one-quarter of a scanning period T respectively. Therefore, the signals delayed successively by one-quarter of the scanning period T are inputted to gate circuits G1-G4. Synchronizing with a vertical synchronizing signal (b) sent from a synchronizing signal generator S, a control signal generator C sends triangular pulses with time width T/4 to the circuits G1-G4. The signal (b), on the other hand, is inputted to a deflecting coil TC to be synchronized with the field of the image pickup tube P. Thus, an output obtained by dividing equally the period of the signal (a) by four is obtained from the circuits G1-G4 and applied to control electrodes 51-54 of a cathode-ray tube B. The cathode-ray tube B is therefore scanned four times in every field period to increase its brightness.

In this case, a transistor array 6 is kept off and resistances 31-3n set at the front of an earth resistance 8 are reduced in that order. Thus the input of a NOT gate 7 is set at a high level. Therefore a point C is set at level '0' and a microprocessor 5 receives an interruption signal. The processor 5 detects an interruption and starts to turn on and off the array 6. At the same time, the processor 5 performs the trouble processing according to a program and turning of a light emitting element continuously while the array 6 is kept on to display the trouble.
