摘要： A matrix panel display apparatus includes plural signal lines and plural scanning lines intersecting each other and, near each intersection point, a picture element including a picture element electrode, a counter electrode, a display medium disposed between the picture element electrode and the counter electrode, and a transistor for applying image signals from the signal line to the picture element electrode. The transistor is controlled in response to scanning signals received on a scanning line. An auxiliary signal generating circuit generates auxiliary signals for increasing effective voltages of the image signals and applies the auxiliary signals to the picture elements while each of the transistors is in a non-conducting state and each of the picture elements is not selected. Preferably, the auxiliary signal generating circuit applies the auxiliary signals to the picture elements during a predetermined period in which all of the transistors are in the non-conducting state and none of the picture elements is selected.

摘要： To reduce a change in an electric current flowing through a cold cathode discharge lamp caused by a change in power source voltage. There is provided a cold cathode discharge lamp lighting circuit, in which a secondary high voltage of a transformer 13 is changed by controlling an oscillating period of a ROYER oscillating circuit 12 by a duty ratio of a PWM signal, to thereby control an amount of the electric current flowing through a cold cathode discharge lamp 11. In this lighting circuit, a resistor Rx is additionally connected between an inversion input terminal of a comparator X4 for generating the PWM signal and a power source, and a power source voltage divided by resistors Rx and R20 is inputted to the inversion input terminal. Thus, when the power source voltage is changed in an increase direction, an oscillating voltage is increased and the electric current flowing through the cold cathode discharge lamp begins to increase. However, since a voltage inputted to the comparator X4 through the resistor Rx is increased, an H (high voltage) period of the PWM signal is shortened and the oscillating period of the ROYER oscillating circuit is shortened, so that the electric current flowing through the cold cathode discharge lamp is reduced. The change in the electric current caused by the change in the power source voltage is reduced by this operation in a reverse direction.
摘要翻译：为了减少由电源电压变化引起的流过冷阴极放电灯的电流的变化。提供了一种冷阴极放电灯点亮电路，其中变压器13的次级高压通过控制ROYER振荡电路12的振荡周期通过PWM信号的占空比来改变，从而控制流过冷阴极放电灯11的电流。在该点亮电路中，电阻器Rx另外连接在用于产生PWM信号的比较器X4的反相输入端和电源之间，以及由电阻Rx分压的电源电压并且R20被输入到反相输入端子。因此，当电源电压沿增加方向改变时，振荡电压增加，并且流过冷阴极放电灯的电流开始增加。然而，由于通过电阻器Rx输入到比较器X4的电压增加，PWM信号的H（高电压）周期被缩短，并且ROYER振荡电路的振荡周期缩短，使得流过冷阴极放电灯减少。通过在相反方向的该操作来减小由电源电压的变化引起的电流的变化。
