Title: Input circuit
Inventor: SEKI SHOHEI
IPC: H03K17/04
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce the difference in delay time of an output signal for rise and fall of an input signal whose level has a wide range. SOLUTION: An input signal Vi having an AC waveform is transmitted to an input node N1 through a coupling capacitor 12. A threshold voltage is given from an inverter 23 to a bias node N2, and the input node N1 is biased through a terminating resistance 21 with respect to DC. A depletion field effect transistor(FET) 31 shows a constant resistance characteristic in the case of the voltage between the drain and the source equal to or lower than the threshold and shows a current saturation characteristic in the case of the voltage between the drain and the source higher than the threshold. Therefore, the current flowing to the input side of an inverter 32 is limited to a certain value even if an input signal Vi is increased, and the delay time of an output signal Vo accompanied with polarity inversion of the input signal Vi is shortened.

Abstract: PURPOSE:To prevent seizure phenomenon by moving the end part of a screen at a prescribed timing when the screen different from a display part in screen size is displayed. CONSTITUTION:The superimposing width of a picture pattern part X is widened, when a blanking pulse BLK1 is outputted from a blanking pulse generation circuit 27, and narrowed, when a blanking pulse BLK2 is outputted. The superimposing width of the picture pattern part X is expanded and contracted depending on that either blanking pulse BLK1 or BLK2 is outputted and right and left end parts are moved by the expansion/contraction of the right and left display widths of the screen 12. Thus, when the changing cycle of the blanking pulse BLK1 and BLK2 is properly set, boundary lines between the screen and side pannels 13 and 14 are not fixed at one point for a long time, at a case when the screen of aspect ratio 4:3 is displayed for a long time. Consequently, the seizure phenomenon is not caused.
