X와 Y전극을 구비하고 박막 기술에 의해 구성된 화면 표시기 특히 2차원 교류 전계발광 표시기를 구동하는 방법에 있어서 전체 구동전압의 절반보다 더 낮은 변조전압이 사용되고, 선택전압이 X 전극중 한개의 전극에 가해지고 다른 Y 전극은 입력이 없으며, X 전극의 대부분이 입력이 없는 동안 변조펄스가 Y 전극에 가해지는 방법에 가해지는 방법에 의하여 선택펄스와 변조펄스의 위상을 변경함으로써 표시기의 구동전압의 양의 펄스와 음의 펄스 모두 변조 전압으로 인가되는 것을 특징으로 하는 화면표시기 특히 교류 전계발광 표시기를 구동하는 방법.In a method of driving a screen display, particularly a two-dimensional AC electroluminescent display, having X and Y electrodes and constructed by thin film technology, a modulation voltage lower than half of the total driving voltage is used, and the selection voltage is applied to one of the X electrodes. The amount of driving voltage of the indicator is changed by changing the phase of the selection pulse and the modulation pulse by the method in which the modulation pulse is applied to the Y electrode while the other Y electrode has no input and most of the X electrode has no input. A method for driving an on-screen display, in particular an AC electroluminescent display, wherein both pulses and negative pulses are applied at a modulating voltage. 제1항에 있어서 변조펄스는 직류성분이 발생되지 않도록 연속적인 양 및 음의 구동펄스의 정부의 대칭적으로 위치됨을 특징으로 하는 방법.2. A method according to claim 1, wherein the modulation pulses are symmetrically positioned of the positive and negative driving pulses so that no direct current component is generated. 제1항 또는 제2항에 있어서 구동 전압의 극성이 충전 지기의 중앙에서 적어도 대략적으로 역전됨을 특징으로 하는 방법.The method of claim 1 or 2, wherein the polarity of the drive voltage is at least approximately reversed at the center of the charge base. 제1항 내지 제3항중 어느 한항에 있어서 연사길이 변조가 사용됨을 특징으로 하는 방법.4. Method according to any one of the preceding claims, characterized in that continuous length modulation is used. 제1항 내지 제4항중 어느 한항에 있어서 전폭변조가 사용됨을 특징으로 하는 방법.The method according to claim 1, wherein full width modulation is used. 제1항 내지 제5항중 어느 한항에 있어서 펄스폭 변조가 사용됨을 특징으로 하는 방법.6.
