Title: Image display device
Inventor: TANIGUCHI HIROSHIGE
IPC: H01J31/12
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a good image which disperses the noise generated by the rising/trailing current changes of pulse width modulation(PWM) waveforms and superimposed on an analog video signal and has inconspicuous noise by providing a circuit generating pulses having different rising positions or trailing positions. SOLUTION: The rising position of a PWM waveform is determined based on the comparison result between the count output of a PWM counter 51 and the digital video signal input by a comparator 52, and the trailing position of the PWM waveform is determined by the leading edge of the PWM period pulse generated by a PWM period pulse generation section 50. Load data switching pulses are generated by a load data switching pulse generation section 61, and the load data of the horizontal counter of the pulse generation section 50 are changed at every horizontal scanning period. The noise generated by the rising/trailing current changes of PWM waveforms is dispersed at optional positions during the horizontal scanning period, and the noise can be reduced.

Title: Analog counter circuit
Inventor: KOIZUMI YUJI
IPC: H03K23/46
Filed: 1988-02-04
Abstract: PURPOSE:To count lots of pulses with a few circuit components and to easily vary the count by forming the analog counter circuit through the connection of a voltage conversion circuit and a voltage comparator. CONSTITUTION:With an input terminal kept at L level to keep the counter in the ON state, when a clock phi1 changes from H to L and a clock phi2 changes from L to H, a potential of a connecting point between a source and a gate of a MOS transistor(TR) M1 rises, the drain potential is decreased, the TR M1 is turned off, a TR M0 turns on, and the charge is charged in a capacitor C1 from the power supply V1. If the level of the clocks phi1, phi2 changes opposite, the TRs MO:M2 are turned off and the TR M1 is turned on to charge a capacitor C2 by the charge of the C1. The electric charge is transferred one after another through the repetition of the processing above to charge up a capacitor C7, resulting in increasing the noninverting input level of a voltage comparator A. When the level reaches a reference voltage V2 or over, the comparator A is operative and its output level changes from L to H. As a result, TRs M7-M13 are turned on, the electric charge charged in the capacitors C1-C7 is discharged, the level of the output terminal of the comparator A changes from H to L thereby enabling itself to count clocks.
