    • A drive circuit of an LCD is disclosed, by which no image signal having a voltage level over the dynamic range of the video amplifier, and thus erroneous operation of the video amplifier is prevented, thereby supplying normal image signals to the LCD. The drive circuit comprises a clip circuit for clipping the amplitude range of the voltage of a picture signal input from an input terminal; a polarity inversion circuit for receiving the picture signal whose amplitude range was clipped by the clip circuit, and for converting the picture signal so that an inverted signal and a non-inverted signal are alternately assigned to each dot; and a video amplifier for amplifying the voltage level of the converted picture signal by a predetermined amplification degree.
    • 公开了一种LCD的驱动电路,通过该驱动电路不会影响具有超过视频放大器的动态范围的电压电平,从而防止视频放大器的错误操作,从而向LCD提供正常图像信号。 驱动电路包括用于限制从输入端子输入的图像信号的电压的幅度范围的限幅电路; 极性反转电路,用于接收由幅度电路限幅的幅度范围的图像信号,并将图像信号转换为每个点交替分配反相信号和非反相信号; 以及用于将经转换的图像信号的电压电平放大预定放大度的视频放大器。

    • In an image displaying field where there is a tendency which will increase the data to be handled in accordance with the high integration of a display device, a CRT controller according to the present invention improves the superposed display and the responsiveness of the display and drawing operations by dividing a unit clock into a predetermined number to function with high speed and a multifunction display. When image data are to be inputted to or outputted from a refresh memory corresponding to a display frame, the memory content and the display address are assigned at a ratio of 1:n to effect the processings in parallel. As a result, the time period utilized by the display cycle of the prior art can be assigned to the drawing operation so that the processing can be speeded up while making it easier than the prior art to effect the superposed display of letters, symbols and drawings. The resultant effect is that it is unnecessary to increase the number of refresh memories corresponding to the displayed frame and that the external parts can be simplified to contribute to the improvement in the reliability.
    • 在根据显示装置的高集成度存在将增加要处理的数据的趋势的图像显示领域中,根据本发明的CRT控制器改进了叠加显示和显示和绘图操作的响应性 通过将单位时钟分割成预定数量以高速功能和多功能显示。 当图像数据要被输入到与显示帧相对应的刷新存储器中时,以1:n的比例分配存储器内容和显示地址以并行地进行处理。 结果,可以将现有技术的显示循环所使用的时间段分配给绘制操作,使得可以加速处理,同时使现有技术更容易实现字母,符号和图纸的叠加显示 。 所产生的效果是不需要增加对应于所显示的帧的刷新存储器的数量,并且可以简化外部部件以有助于提高可靠性。
